The Most Common Problems with a Machine

For sewing enthusiasts, even professionals, sewing is first and foremost a passion. Spending hours in front of the sewing machine is always a pleasure. But when faced with a malfunction of this tool, this activity then becomes painful. That’s where we learned about the generality of a sewing machine, now let’s move on to the problems that can occur when using it.


Needle Problems

Various complications may occur when you sew. One of the common problems is the needle that breaks easily. It is a headache for the professional sewer because it will waste your time and money. However, there are various reasons that can explain these complications. The needle may be blunt or bent.

To remedy this, you must change it and check its condition frequently, because it must be correctly fitted and adapted to your fabric. It is also likely that the hook is not touching the needle. If so, just position it correctly.

If your machine is out of adjustment, the hook will not rotate properly. The hook’s movement should be coordinated with the rotation of the needle. If the hook touches the needle while it rotates, you might have to contact a specialist.

Mechanical Failures

If your sewing machine is making noises, it may be due to the following two situations: the bobbin is incorrectly placed and needs to be replaced or your hook is low on grease. If they are in the right place and the machine still makes funny noises, your hook may be low on grease. To solve this problem, put a few drops of sewing machine oil on the edge of the hook to eliminate this issue. In order to spread the oil, run the sewing machine idle for a period of time.

When you’re in the middle of a sewing project and suddenly your machine stops, it’s easy to panic. No one likes having their thread break or having a needle break either, but what if it’s not that? It may be that your machine is just sulking, refusing to move forward with its duty. Before you start pulling at the cord, check the plug to see if it’s plugged in. If it is, pull the plug out of the wall and then back in again. It may have been knocked out of the socket by accident. Then check the hook that catches the wire around the end of the cord. Sometimes it gets caught when you’re winding up a bobbin or spool of thread. If you’ve checked both and everything seems to be fine, you need to look at the flywheel release screw.

If you’ve checked all of these things and still can’t figure out what’s wrong, try this: unplug your machine, hold down the brake pedal with your foot, and turn the handwheel towards you (you may need to turn it back towards you once), and then push back on the reel until there is slack in your thread or bobbin. Then plug in your machine again and turn on your power switch. The machine should run now.


Stitch Problems

A machine skipping stitches often shows up when sewing. The most likely cause of this failure may be a dull needle or the wrong needle for the fabric being worked on. To correct this defect, simply replace the needle.

The hook may also be off its regular location. In order to see if this is the case, you need to change the needle and fix it slightly lower and test. If it works, you need to call a technician, because it confirms the problem with the hook.

There is also the discomfort caused by the yarn-making loops. If it is the bottom thread, you must tighten the tension block to raise the thread tension from the spool.

If the top thread is affected, it is likely that the bobbin is incorrectly mounted or its case is loose.

To remedy this, you only have to tighten the bobbin case with a screwdriver.

Some Extra Tips

The last thing most people want to do with their free time is taken apart a sewing machine, but it’s a common problem that the bobbin case breaks, which can be prevented. The Apollo bobbin case (you’ll find this on many cheap machines) is often a weak point. It’s made of plastic and is susceptible to becoming damaged or cracked. Everything on this must be very smooth, without any nicks or cracks. So that the thread (to form knots) can slide (pull) over it without any problems. If the plastic isn’t smooth and cracks, it could break and fall apart. Now you have a sewing machine that doesn’t work at all!

To ensure the correct coil is installed, the coil must be 20.4mm wide and 11.5mm high in the center (it is 11.0mm thick at the very edge, so it is slightly curved).

The bobbin area of a sewing machine is an often overlooked component of the sewing machine. It’s sort of like the engine of a car: you don’t see it unless there is something wrong with it. You should clean it regularly and keep it maintained, though, because if it gets clogged up with thread or lint, or if things start to rust and get stuck in there, your machine will stop working as it should.
