Bernina B 435
 

I purchased a Bernina in September, yesterday I went to a class and the machine had to "warm up" for over an hour. Has anyone else had this happen. I use this machine weekly.

I am not sure what you mean by "warming up". I do know that things that are computers they say to let them "warm up" before using them if they have been left in a cold environment.....was it cold where you are? I live were it can get well below zero on cold winter days....my long arm...I have to turn on and it helps to run it a bit without thread just to get it running nice and smooth....she is a bit rough for the first few minutes.....

I have a 770 and a 150 and have not had that happen to either one.

Um, no, that's not alright. The L-print is faulty and needs to be replaced. Bernina warranties their circuit boards for 5 years. You should take care of it ASAP!
