Hello fellow Quilters! I'm having a strange problem with my brand-new Juki TL-2000Qi and wondering if it has happened to anyone else. For background, I've had this machine for a month (received it for Christmas from my husband) and have used it for about 8 hours total for piecing and quilting. In this time, I've cleaned and oiled it once. I last used it Tuesday night (1/11/22) for about 20 minutes of light piecing and it worked perfectly.
When I turned on my machine yesterday morning, immediately any effort to use the foot pedal in forward sewing motion resulted in engagement of the automatic thread cutter. When it first happened I thought my foot must have slipped and pressed down (backward) on the pedal, but when I tried again it kept happening. The automatic thread cutter engages as expected with the switch on the body of the machine and when pressing down (backward) on the foot pedal, but also when pressing forward on the foot pedal to sew. Of course, this makes sewing impossible. As a note, the automatic thread cutter does not engage when turning the handwheel.
In response, I removed the bobbin case, bottom cover, and throat plate and cleaned everything, inspected for threads, and oiled the machine again in the locations indicated in the user's manual. I unplugged the power cord and foot pedal, turned the machine on and off, and even tried a different outlet. Still, the automatic thread cutter engages with any attempt to sew forward with the foot pedal.
With the throat plate removed, my (mechanical engineer) husband took a look to see what was happening when I pressed down on the pedal. First, he was super impressed with the quality of the parts (go Juki!), but can't see why the thread cutting mechanism would be engaging with forward motion on the pedal. He suspects it's either an electronic issue with the foot pedal itself or related to something being slightly off in the mechanisms deeper in the machine that we can't see.
I can't imagine why/how this happened, as I didn't touch my sewing machine between my last use Tuesday night and the foot pedal issue yesterday morning. I have been sharing glowing reviews with my sewer friends/family about this machine and am beyond disappointed that it's not working properly, especially with only several hours of use in a month.
Has anyone heard of this before? I contacted Juki and am hoping they'll be able to help, as my machine is definitely still under warranty. Thanks in advance for any insight!
