Re: Bobbin Winding issues on 10000 & 550e

Different symptoms, but the same problem. The bobbin winder clutch is sticking, which causes the needle to operate at full speed, and as it slips a bit, a squeal is generated. This has NOTHING WHATEVER to do with circuit boards. It's purely mechanical. To fix it she should pull off the hand wheel (It just snaps on) and disassemble the clutch, taking photos in the process to easy reassembly. Clean and lubricate as needed, then reassemble. That may or may not fix the failure of the winder to stop, but it needs to be done.

Mushy bobbins are due to there not being proper tension in the thread going to the winder. This usually is due to debris building up around the tension spring. DO NOT try to adjust this by turning the screw visible through the hole in the top cover of the machine. That will not fix the problem, but it will create new ones. What needs to happen is that the top cover is removed so the screws holding that cover over the winding path can be removed. Once that cover is off the problem will be easy to fix.
