I worked on an Electrolux washing machine yesterday. Top load machine, fairly new.
Customer complaint of squealing, at high speed. Turning the drum by hand (from inside the machine) produces no noise. Replace the belt.
Still squealing. Any ideas what to look for? My thought is to take the front panel off, and run it without the front panel. See if it's possible to locate the squeal by ear.
I've Googled and Startpaged, and no hits for that kind of problem.
