Low bobbin thread indicator not working on Pfaff 2044.
Using clear bobbins.
Is there a lamp or sensor that can be replaced?
Have you tried to take out the bobbin case, close the door, and see if the indicator comes on? If the indicator works with no bobbin case, then the machine is working. You may have what we call foggy bobbins. Bobbins that are scratched or cloudy. Make sure you try a new one.Also check for lint blockage in the hook area or the bobbin case. If it still doesn't work, the indicator on the door may have gotten pushed in. That sometimes happens. You should feel the indicator eye protruding out a little bit from the door. You can open the area where the indicator is on the door to push it back out. Sometimes the indicator wire behind the hook gets broken. That would require you do disassemble the freearm cover area. Start with the simple things first.
