What to Know About Janome Sewing Machines

In 1925, Yasaku Ose, the man responsible for the round bobbin’s invention, established the enterprise that would become Janome. In 1954, the corporation was renamed. The phrase “Janome,” which refers to the world-famous circular bobbins, is a Japanese term for snake-eye.

Japan’s postwar sewing machine industry took off in 1954, and many of the types you know and love were created at this time.

Over the years, Janome has come up with a slew of groundbreaking sewing machine designs. During 1964, a research and development center was set up expressly for the company’s ongoing pursuit of innovative technology. Memory 7, the world’s first programmable sewing machine, was developed at the research facility.

Today, Janome machines are known for their superior quality and cutting-edge technological capabilities. In the world of professional tailors, seamstresses and designers, Janome is a popular brand.

Thailand and Taiwan are two of Janome’s manufacturing locations. Janome’s unique technology is used extensively in these operations to construct the sewing machines’ minuscule but precise parts.

All of this points to the fact that Janome sewing machines are top-notch. But even the best sewing machines require a little TLC from time to time.

Troubleshooting Janome Sewing Machine: 18 Common Issues

It’s not uncommon to have minor issues while sewing even when you’re using a high-quality Janome sewing machine!

Tips for addressing the 18 most common issues you may experience when using a Janome sewing machine are provided here.

If you just bought a new machine, be sure to verify the warranty. Many of Janome’s machines come with hefty warranties, however you may lose the guarantee if you attempt to remedy specific issues on your own.

Before beginning any repair work, be sure to turn off your sewing machine completely. If you step on the pedal while mending it, you don’t want your fingers under the needle!

1. Not Stitching

Janome sewing machine repairs

If your Janome sewing machine isn’t stitching, there are a number of possible reasons behind it. Follow these procedures to see if you can uncover the source of the problem!

  1. The power cord and foot pedal plugs should be checked. I know that sounds ridiculous, but it’s possible that you just need to reconnect a loose plug or cord!
  2. Did you remember to switch on your computer, as well? I know you’ll roll your eyes, but you’d be amazed how many times you’ll sit down to sew only to discover that you forgot to turn the machine on!.
  3. Have you just wound a bobbin up to show me? The machine must be set to sew, not bobbin wind. If you forget and leave it in bobbin-winding position or bobbin-winding mode on computerized models, it will not stitch and may produce an odd noise.
  4. A thread tangle is most likely to be the cause of a machine that will not turn the handwheel after being turned on. Check see the “jammed thread” section below for help in this situation!

2. Jamming

When a sewing machine becomes stuck, it’s usually because the upper thread has broken. In either case, the tension settings need to be tweaked or the thread may have come loose from its guide.

Using one of these methods can result in a massive tangle of thread on the fabric’s underside. They may call it “bird’s nest” since that’s what it appears like to the untrained eye!

In order to clear the obstruction:

  1. Your sewing machine should be turned off and unplugged. Prop up your cell phone with the flashlight feature activated if you need a light source!
  2. Remove the presser foot from the material.
  3. When the handwheel is moving, elevate the needle.
  4. Snip the thread under the fabric with a pair of small, sharp embroidery scissors until you can slip the fabric out.
  5. Remove any stray threads from the bobbin case by opening it up.
  6. Remove the needle plate with a little screwdriver and check to see if any twisted threads are trapped beneath it. In most cases, your sewing machine will arrive with the necessary screwdriver. The screwdriver that comes with an eyeglass repair kit can be used if you don’t have one of your own.
  7. Re-insert the bobbin and re-throw the higher thread. To properly line the tension discs, lift the presser foot before threading. Make a few test stitches on a scrap of cloth to make sure everything is going as planned!
  8. If you get a new jam right away, you probably need to raise the strain in the cable. Look for more information on how to deal with tension in the next section of this post!

3. Fabric Stuck

Several simple ways exist for unsticking fabric!

  • When you start sewing and realize you haven’t put the presser foot down, it can be a frustrating experience.
  • Resetting your machine may be the only way you can get it back to normal after using it in an unique mode like “darning” or “free motion.” It’s important to make sure everything is back to normal before you begin stitching.
  • You may also need to reset if you previously used a double-needle stitch setting.
  • An upper thread issue may have created a jammed thread beneath the fabric. Refer to the section above to find out how to remove the jam!

4. Thread Tangles

Many thread tangles occur when the upper thread has been misplaced or damaged. Try re-threading the machine after eliminating the tangle.

If you’ve never threaded a sewing machine before or if your Janome is a brand new machine, read the threading section in your owner’s manual first. On Janome’s website, you can also discover instructional videos for some of their most popular models.

To thread your Janome sewing machine, you simply follow these simple steps:

  1. Snip the old thread close to the spool and carefully drag it out of the needle by drawing it down and out.
  2. Unwind six to ten inches of stray thread from the spool pin.
  3. The thread path is the next step. When using a Janome machine, the path can be represented numerically. Color-coded threads are offered by others.
  4. After the first thread guide, continue to wrap the thread around itself. Move the thread to the next thread guide left.
  5. The thread take-up level should be visible above the sewing machine body if the needle is positioned correctly. Through that as well, make a loop with the thread.
  6. The needle is now in the path of the thread as it descends. This is where you’ll need to insert your thread after you’ve snagged a last thread guide from the needle.
  7. Last but not least, you can either use an automatic needle threader or manually thread the needle.

Thread tangles can occur if you use the wrong type of thread for the fabric you’re working with. Using thread made from the same sort of fibers as the material is a good idea in general. Silk thread works well with silk, and cotton thread works well with cotton cloth.

Certain types of thread may also be difficult for your sewing machine to manage. Using heavyweight thread or buttonholes might cause sewing machines to get stuck.

5. Broken Needle

Janome repairs

The most common cause of needle failure is incorrect needle selection for the thread or material. When sewing with thicker topstitching thread, for example, you’ll require a particular needle. Always start each new sewing project with a fresh needle, so take a few extra minutes to find the ideal one for the task at hand!

Check out these typical needle fixes:

  • Make sure the needle clamp screw is completely tightened. Because of this, it is possible for the needle to snap when it falls down slightly into the bobbin region.
  • Make sure your needle is the right size and kind for the weight and type of cloth you intend to work with.
  • Presser foot and other attachments are required for some fancy stitching patterns. It’s possible to sew with a broken needle if these aren’t aligned.
  • Allowing the feed dogs to move the fabric beneath the needle is a must while using a sewing machine. In order to keep the needle from snapping, you can rest your palm on the cloth to guide it in the appropriate direction, but you don’t want to press or pull on it! The skewed stitching will also be an issue.

6. Needle Unthreading

Thread difficulties, such as the needle fast unthreading the moment they begin sewing, are common for novice sewers. Fortunately, this issue may be resolved quickly and easily.

  1. Before you begin sewing, make sure to lower the presser foot. Without tension, your thread would have fallen out of position if you forgot and left it up. As soon as the needle started moving, it slid free.
  2. Before you begin stitching, gently pull the bobbin and top threads out to the side by about six inches.
  3. While you’re making the initial few stitches, keep those thread tails tucked between your fingers.

Everything becomes second nature after some time, and you don’t give it a second thought when you start a seam!

7. Needle Threader Issues

Many Janome sewing machines include built-in automatic needle threaders, which are a lifesaver. That is, until they decide to stop working. Trying to poke the thread in the appropriate direction requires squinting at the needle’s tiny eye.

However, it’s a good bet that your threader is fine! Check to see if the needle has been elevated. When the needle does not rise any further, stop turning the handwheel.

If you don’t raise the needle high enough, the needle threader may not revolve or align properly.

8. Bobbin Problems

Janome bobbin problems

In reality, bobbin issues are rare because this mechanism is devoid of slack or ambiguous components, such as the top thread route. There are a few common bobbin issues that you may encounter while using your Janome machine.

Try these remedies if you see bobbin thread peeking out of your stitching:

  • Pull the thread tail from the bobbin. Replacing the bobbin with a new one, raise and lower the needle by turning the handwheel and bringing the bobbin thread up with it is the next step. It’s possible that a simple system reset will resolve the issue!
  • The bobbin is the first thing you should check, so be sure you’re using a genuine Janome bobbin.
  • In some cases, using the improper needle size can cause problems with your bobbin. Make sure the needle fits your sewing machine by looking it up in the manual.
  • A bobbin that has been bent or skewed will not spin properly and may even result in ripped bobbin thread. A simple test is to lay down the bobbin and lean over to examine if its flat sides are resting on the work surface straight.

9. Bobbin Tension

The bobbin tension can sometimes need to be adjusted as well, although it is considerably less common than problems with the top thread tension. It’s always a good idea to start by adjusting the upper thread tension to see if it helps. In most cases, you only need to change the bobbin tension if you want to use heavyweight thread or if your machine is over a decade old.

While sewing, you may need to adjust the tension of the bottom thread (bobbin thread) by loosening the bobbin case’s tension screw.

Why do you think this is? If the thread appears wavy or loose, it is likely that the tension needs to be tightened. While a result, you may require less bobbin tension to avoid puckering or even breakage as you sew.

In order to alter the bobbin tension:

  1. Remove the case for the bobbins.
  2. Let go of the bobbin.
  3. Use a Sharpie to mark the position of the bobbin case screw. If you change your mind, you may always go back to the default tension settings.
  4. To turn the screw, grab a teeny, tiny screwdriver. Turn the screw clockwise to increase tension. Counterclockwise rotation eases strain.
  5. You want to turn the screw in tiny increments. After each modification, test and sew a few threads to see if the tension problem has been resolved.

10. Tension Issues

Janome tension problems

When adjusting the screw, be sure to do it in modest increments. Make a few stitches and check to see if the tension is correct after each adjustment.

Here’s the thing: on medium-weight fabrics using basic cotton or polyester thread, you can usually utilize the machine’s preset average tension settings. But if you change the weight of the fabric or the type of thread, you’ll have to play with the tension for a while.

A test on a sample of the cloth you intend to use is the quickest way to precisely set the tension for your specific sewing job.

  1. What do you see? Do the stitches on the bottom of the fabric appear to be unkempt? Try sewing again with a higher tension setting to see if the problem is solved.
  2. You can also experiment with lower tension settings if you notice loose threads on top of the material when you test-sew.
  3. Lowering the tension will help you avoid having seams that are too tight or puckered.

11. Squeaking Noise

If you hear a squeaking noise during stitching, immediately stop! A odd noise in your car isn’t something you want to deal with while driving, would it?

When you sew, you may hear squeaking or peeping noises for one of two reasons. For older metal machines, you may need to lubricate them. Modern machines are sealed and pre-lubricated, so unless your handbook says otherwise, there’s no need to add oil!

You could also get a warning from your computer when something goes wrong. To code on the scream, this squeak or piping sounds usually comes with a cautionary explanation.

12. Grinding Noise

Warning: Stop at once when you hear a high-pitched grinding noise! When the machine is unable to move the cloth because of a thread jam, it makes this sound. When lint and dust accumulate between your machine’s moving parts, this problem frequently emerges.

Cleaning and maintenance are essential for all machines, no matter how modern or high-tech they may be. Please note that comprehensive cleaning instructions unique to your Janome model can be found in your manual.

You may avoid hearing that grinding sounds in the future by following these simple cleaning measures.

  1. Use a lint brush or a clean cosmetics brush to remove any lint from the bobbin region. Make a mess with the bobbin case and bobbin! Under the needle, a lot of lint might accumulate.
  2. Remove the presser foot and needle before carefully cleaning the bobbin area if you have a top-loading bobbin. Replacement of the needle is a good idea during this time. After eight hours of sewing, you should change your needle!).
  3. Remove any lint from the feed dogs by brushing it away carefully.
  4. Try opening the side of the machine to get to and clean the upper thread path. Try clearing the passage of any lint by running a clean thread through it.
  5. Remember to put a cover on the machine when you’re not sewing so it doesn’t get dusty!

13. Broken Thread

For a variety of causes, threads can snap or fray repeatedly. Make your way through this list of solutions in search of the one that works!

  1. Start by rethreading your machine. A test run may reveal whether the problem was caused by a loose thread being snagged on something, so give it another go and see if it fixes it.
  2. Second, check the upper thread’s tension settings. The thread can snap if the tension is too tight.
  3. If so, how many spool caps does your machine have? To avoid the thread being tangled around the spool pin and breaking, you may want to try a different one.
  4. Inspect all of the bobbin’s components (bobbin case, bobbin hook, needle and plate) for signs of wear and tear. Fraying or breaking of the thread is possible if it gets caught in these places.
  5. Find out if the thread you have on the spool pin is of high quality by conducting an internet search for the brand name. It’s best to avoid using cheap thread for long-term sewing projects!

14. Loose Stitching

Loose stitching is almost always the result of improper threading on the sewing machine. The machine can’t exert tension on the thread unless the thread loops through each tiny guide and tension disc precisely. It creates shaky stitches if you don’t put any pressure on it!

You may also wish to check that your needle and thread are compatible. Consider what kind of thread or material you’ll be using before purchasing a needle.

Finally, you may also need to check your upper tension settings. You can refer to the section on tension issues earlier in this article for help!

15. Tight Stitching

Finally, you may also need to check your upper tension settings. You can refer to the section on tension issues earlier in this article for help!

  1. For good measure, check your top tension settings. The section on tension concerns at the beginning of this essay is a great resource!
  2. Make sure you’re using the correct needle for the material. If you don’t use a ballpoint needle, the knot material may pucker or strain.
  3. Also, be sure to keep an eye on the discussion thread! Stitching can be distorted even if you use the correct type of thread because of its weight. Instead of a heavyweight thread, a lightweight one is required for the thin cloth.
  4. As a result, it is possible to avoid puckered seams by using a stabilizer or interfacing. Slinky or light-weight materials benefit most from this technique.

16. Skipped Stitches

A problem exists if you can notice gaps between stitches on the fabric’s surface when inspecting a seam. Rethreading the machine is a good place to start when you’re having stitching problems. However, if that doesn’t resolve the issue, follow these steps:

  1. If the needle breaks, replace it. In the case of a bent or dull needle, the upper thread may not be able to capture the bobbin thread to form stitches.
  2. Similarly, each sewing project requires a different type of needle. A different type of needle is needed for silky fabric than for canvas or cotton, for example.
  3. Make one more adjustment in the top tension levels and see if that helps. Try a lower number if it doesn’t work. Check to see whether the tension can correct the skipped stitches by repeating this procedure.

17. Stretch Fabric Seams Loose

Uneven or unstable seams are more common with stretch fabric than you’d expect when sewing it, making it a unique challenge.

Preventative measures include:

  • Use a ballpoint pen needle. Stretch needles from high-quality brands are also available.
  • Make sure you follow the manufacturer’s instructions for pre-washing the cloth. To avoid compromising the stretch recovery, you might need to use cold water.
  • Straight stitches should be avoided. Other designs, such as zigzags, will be able to elongate with the material.

18. Computer Warnings

Janome jam

Many of the more contemporary Janome sewing machines come equipped with touchscreens or other types of display screens. Stitch patterns and sewing settings can be entered into these panels. In the event of a malfunction, these screens display error messages or codes.

To find out what to do if your vehicle displays any of these error codes, consult your owner’s manual. It’s possible that the task at hand necessitates the use of a different presser foot. Other times, it may be necessary to have the machine serviced by a specialist.

How to Take Apart a Janome Sewing Machine

When cleaning your Janome sewing machine, you may need to remove the machine’s plastic case. Every model is different, however a little screwdriver is usually required for this technique.

  1. Before you start disassembling anything, take some pictures. Get a small cup or dish to hold any loose screws you may have.
  2. Shut off and unplug the machine if it is still on.
  3. Locate the screws that are keeping the plastic housing in place with a screwdriver. There are usually numerous of these on the bottom and on either side of the machine.
  4. Remove both the bobbin winder screw and the bobbin.
  5. The bobbin and bobbin casing can be removed now.
  6. Remove the needle plate to make it easier to reach the bobbin area and feed the dogs. Remove the needle plate.

How Do I Reset My Janome Sewing Machine?

Depending on the model and make of your Janome sewing machine, there are various alternative ways to reset it.

First, check to see whether you’ve forgotten to turn the machine back on after completing a certain job. To sew, you must reset the machine to sewing mode after winding the bobbin, for example.

Second, many new computerized models allow you to go through a more complicated process. To put the machine into test mode or to reset it, particular codes and patterns must be entered.

For this procedure, you need to consult your Janome manual or the company’s website! As a result, each machine’s results will be unique.

Janome Sewing Machine Repair Manual

You may learn how to do basic maintenance and repairs on your Janome sewing machine by consulting the owner’s manual or repair manual. Don’t worry if you’ve lost your original copy! Most of Janome’s newer machines include manuals that may be downloaded from the company’s websites.

If your computer is an older model, you might be able to find a used hard copy on eBay or Etsy. If you’re looking for a digital copy of a sewing pattern, you may be able to discover one in a sewing discussion group online!

One of the most important things to remember is to use the instructions for your individual Janome device. The instructions that come with each Janome sewing machine are unique since each one is slightly different!
