Velleman DEM100 Problems and Solutions

some common issues and problems with the Velleman DEM100 and their solutions, as reported by experts:

• The machine doesn't turn on. Make sure that the power cord is plugged in securely to both the machine and the wall outlet. If the machine still doesn't turn on, check the fuse or circuit breaker to make sure that they haven't tripped.
• The machine doesn't sew. Make sure that the needle is inserted correctly and that the thread is threaded through the machine properly. If the machine still doesn't sew, check the tension of the thread.
• The machine skips stitches. Make sure that the needle is the correct size for the fabric you are sewing. If the needle is too large, it can cause the machine to skip stitches. You may also need to adjust the tension of the thread.
• The machine jams. Make sure that you are using the correct type of thread for the fabric you are sewing. If you are using a woven fabric, you should use a woven thread. If you are using a knit fabric, you should use a knit thread. You may also need to adjust the tension of the thread.
• The machine makes a loud noise. This could be a sign of a problem with the motor or the drive belt. If you hear a loud noise, stop using the machine and contact a qualified technician for repairs.

Here are some additional tips to help you avoid problems with your Velleman DEM100:

• Clean the machine regularly. This will help to remove dust and lint that can build up and cause problems.
