The janome 9450 is one of the most popular computerized sewing machines from Janome loved by many sewing and quilting enthusiasts. With its advanced features like large work area, superior lighting, and hundreds of built-in stitches, it’s easy to see why this model is a favorite.

However, like any complex electronic device, the janome 9450 can sometimes develop issues that affect performance. In this detailed post, we’ll explore the most common janome 9450 problems users face and solutions to diagnose and fix them.

Whether you’re experiencing thread tension problems, needle breaking, bobbin issues, or error messages, this troubleshooting guide will help you get your precious janome 9450 back in working order. Let’s get started!

Needle and Thread Breaking Problems

One of the most frustrating janome 9450 problems is needle and thread constantly breaking while sewing. This can be caused by several factors:

Using the Wrong Needle Type or Size

Using the incorrect needle type or size for your fabric is one of the biggest reasons for frequent needle breaking.

Solution: Always check your janome 9450 manual to determine the proper needle choice for your fabric thickness and type. Using heavy duty needles like denim needles for thick fabrics and smaller, sharp needles for light fabrics can prevent breakage. Also, change your needle frequently to avoid dulling.

Incorrect Thread Tension Setting

If the thread tension is too tight, it will put extra strain on the thread and cause breaks.

Solution: Refer to the tension guide in your janome 9450 manual to check the recommended settings for your thread type and weight. Make gradual tension adjustments and test stitch on fabric scraps until you find the optimal tension that doesn’t break or puckers stitches.

Poor Quality Thread

Cheap, poor quality thread that is unevenly spun or thin can easily break, especially under high tension.

Solution: Invest in high quality thread from reputable brands like Gutterman, Mettler, or Coats & Clark. Quality thread resists breaking and gives your sewing projects a professional finish.

Bobbin Problems

Bobbin issues like incorrect insertion and threading can totally disrupt your janome 9450 sewing. Here are some common bobbin problems and fixes:

Improper Bobbin Insertion

If the bobbin is not inserted correctly in the bobbin case, it can cause tangles, breaks, uneven stitches and more.

Solution: Carefully follow the instructions in your janome 9450 manual for inserting the bobbin and ensuring it is fully seated in the bobbin case before inserting in the machine.

Incorrect Bobbin Winding

An incorrectly wound bobbin with uneven, loose or tight thread can lead to sewing problems.

Solution: When winding bobbins, use the automatic winder on your machine and start with an empty bobbin. Follow all the steps exactly to wind the thread smoothly and evenly around the bobbin for optimal performance.

Dirty or Damaged Bobbin Case

Over time, lint and thread fragments can build up inside the bobbin case. This debris can obstruct the bobbin and disrupt sewing.

Solution: Check the bobbin case in your janome 9450 and clean it regularly using a small brush, compressed air or sewing machine oil. Replace the bobbin case immediately if damage is found.

Thread Tangling and Tension Problems

Frustrating thread tangling and tension inconsistencies when sewing can be caused by:

Knotted, Twisted Thread

If thread unwinds and twists when sewing, it can get easily tangled and stuck.

Solution: Try re-threading the top and bobbin threads to eliminate any knots or twists before starting your project. When sewing, unwind thread from spool slowly and evenly.

Incorrect Thread Tension

Improperly balanced tension settings between the top thread and bobbin can cause messy tangles.

Solution: Check the thread tension recommendations in the janome 9450 manual for your thread type. Make small tension adjustments in both top thread and bobbin case while testing on fabric scraps until optimal smooth feeding is achieved.

Skipping and Missed Stitches

Stitch skipping while sewing can leave gaps in your projects. Here are some potential causes and fixes:

Bent or Dull Needle

Using a needle that is bent or has a dull point can cause it to mis-stitch by missing fabric or catching threads.

Solution: Replace your needle frequently before it becomes worn out. Insert a fresh sharp needle like Schmetz or Organ brand to prevent skipped stitches.

Improper Needle Insertion

If the needle is not fully inserted and secured in the needle clamp, it may move around, causing skipped stitches.

Solution: Use the markings on your janome 9450 needle plate as a guide and push the needle up into the clamp as far as it will go. Securely tighten the needle clamp screw.

Incorrect Thread Tension

When thread tension is too loose, the slack can cause skipped stitches as the thread loops under the fabric.

Solution: Check the janome 9450 manual for proper thread tension settings. Tighten top thread tension gradually while testing on scraps to find optimal tension that avoids skipped stitches.

Power Issues

If your janome 9450 suddenly won’t turn on or power up, there could be a quick fix:

Loose Power Cord Connection

A power cord that has worked loose from the power inlet on the machine or outlet can cut power.

Solution: Unplug and firmly reinsert the power cord into the machine and wall outlet. Use a heavy duty extension cord if needed to secure the plug.

Faulty Outlet

An outlet that is overloaded or defective won’t provide consistent power.

Solution: Unplug from the suspect outlet and try plugging the machine into a different outlet that is confirmed to be working properly.

Internal Wiring Problems

Damage or defects with the electrical components inside the machine can disrupt power.

Solution: If power issues persist in multiple outlets, the internal wiring of the janome 9450 may need professional evaluation and repair. Contact an authorized Janome repair technician.

Machine Jamming

Mid-project jams that completely stop your sewing are incredibly aggravating. But don’t panic – try these steps:

Improperly Inserted Bobbin

If the bobbin hasn’t been fully inserted into the case or is sitting in the machine at an angle, it can jam up.

Solution: Carefully remove the bobbin case, check the bobbin is securely in place, then reinsert ensuring it is sitting flat and positioned correctly.

Needle or Thread Issues

Bent needles or accumulated lint and thread remnants around key areas can obstruct fabric flow.

Solution: Replace bent needles immediately. Clean around the feed dogs, bobbin case, and shuttle area using a brush, compressed air canister or vacuum to remove built up debris.

Unusual Noises

Hearing concerning new grinding, knocking, or whining noises from your janome 9450 can be worrying. Here are two common causes:

Lack of Lubrication

Insufficient lubrication of internal parts can lead to increased friction, causing loud noises when sewing.

Solution: Apply light sewing machine oil to any parts recommended for oiling in the janome 9450 manual. Follow frequency and quantity guidelines carefully to avoid over-lubrication. High-quality sewing machine oil like Singer or Oil-0-Matic work best.

Issues with Internal Components

Excessive noise can signify a problem with internal parts like belts, gears, motors or driveshaft.

Solution: Strange new noises often require diagnosis and repair by a professional sewing machine technician to determine which part is faulty and needs replacement. Contact Janome support or your local dealer.

Fabric Feeding Problems

Accurate fabric feeding is crucial for professional sewing results. Here are some potential issues:

Disengaged or Clogged Feed Dogs

Feed dogs that sink too low or have trapped lint won’t grip and move fabric.

Solution: Before sewing, ensure the feed dog lever is set to the raised position for fabric engagement. Clean around the feed dogs thoroughly with a brush to remove any lint buildup.

Improperly Installed Presser Foot

A detached or uneven presser foot can allow fabric to shift and distort stitches.

Solution: Check that the presser foot is firmly attached and the center screw is tightened. The foot should sit flat and even on the feed dogs. Adjust foot pressure if needed.

Fabric or Thread Issues

Hard to feed fabrics like vinyl and leather or poor quality, fuzzy threads can impede feeding.

Solution: Trial different needles and presser feet designed for difficult fabrics. Ensure you are using good quality, lint-free thread. Supporting fabric edges with tissue paper can also help.

Computerized Control Issues

The janome 9450’s computerized functions are a huge asset for sewing – when working properly. But technical malfunctions can occur:

Malfunction in Electronic Components

Like any appliance controlled by a computerized motherboard and LCD display, the janome 9450 has internal electronic components that can fail over time and cause operation issues.

Solution: The janome 9450 screen will often show an error code when there is a detected malfunction. Check the troubleshooting section of your instruction manual and follow prompts to identify the problem component and steps to fix it. For serious errors, the machine may need professional diagnosis and servicing to replace damaged parts.

Complete Failure of Computer Functions

In rare cases of full computer failure, no error message will appear and the entire machine will be completely unresponsive.

Solution: No do-it-yourself fix is possible with complete computer failure. The machine will need extensive repair by Janome technicians to determine and replace any damaged electronic components. Contact Janome support immediately for diagnosis.

Preventative Maintenance

While even well-maintained machines encounter problems occasionally, you can help prevent many common janome 9450 issues with regular care:

• Keep machine free of dust and lint buildup by vacuuming the bobbin and feed dog areas often.
• Use compressed air to routinely clean under throat plate and around feed dogs.
• Replace needle every 2-4 projects, or immediately if stitches look defective.
• Ensure you are threading correctly by following diagrams carefully.
• Wind bobbins before each project and check for smooth, uniform winding.
• Use only good quality thread and replace old thread to minimize breaks.
• Schedule adjustment and oiling by a professional every 1-2 years.

With proper use and preventative maintenance, your janome 9450 should provide years of smooth, uninterrupted sewing! But if problems do creep up, use this troubleshooting guide to quickly diagnose and resolve many common issues.
