Bosch Serie 8 front loader, only 2 years old. Yesterday, it started squeaking quietly during the spin cycle - BUT only when spinning CCW. Tried to nip it in the bud…. Emptied the filter - nothing. Removed the rear panel and tensioned the belt - no difference. Also tried some window cleaner on the belt but no difference. Removed the belt altogether and when i hand turn the drum i hear the squeak now in both directions. Any ideas? I tried to remove the nut holding the barrel but to no avail…; perheaps its not a nut? anyways. any help appreciated

Most likely the drain pump. Check for something in it. Here’s how: https://www.youtube.com/watch?v=qqj0lrk1
