Issues Fitting Washer Belt
Good afternoon. I've been having problems trying to re-install a belt that came off earlier today. I have looked at the repair help page and numerous youtube videos but I am still having trouble, this might end up being a silly thing that I am just overlooking but I am lost for the time being.
The problem is that the motor shaft and the drum pulley do not align with each other, so when I put the belt on and start rotating the drum pulley the belt will eventually slip off. Now I have checked and the drum pulley seems tight, it does not rattle nor does it move more than what seems like the regular movement necessary for it to spin. I'll attach a couple photos and a video, hopefully that helps. The washing machine brand is a ProLine Logic, I'll also attach an image in case that helps.
Any help will be much appreciated,
Thank you in advance.

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Washer belt slips off due to pulley misalignment
- The problem
- A ProLine Logic washing machine belt had come off and could not be re-fitted successfully. The poster reported that the motor shaft and drum pulley did not line up, so the belt slipped off again when the drum pulley was rotated by hand.
- Likely cause
- The accepted reply said that if the pulleys are genuinely out of line, there is likely a fault with either the motor or drum assembly. Suggested causes were a broken or loose motor fixing arm, drum play from worn bearings, or a worn pulley. It was also noted that on some machines the belt may need to sit further back or forward on the motor pulley if the pulley grooves are deeper than necessary.
- What fixed it
- No confirmed repair was posted. The accepted advice was to check whether the belt position on the motor pulley could be adjusted for alignment, and if the pulleys were truly misaligned, to investigate for a loose or damaged motor mounting, worn bearings or a worn pulley. The exact repair was not confirmed.
- Checks to try
- Checked that the drum pulley seemed tight and did not rattle
- Observed that the motor shaft and drum pulley did not align
- Observed that the belt slipped off when the drum pulley was rotated
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Hello there. Sometimes the grooves on the motor pulley are much deeper than necessary and the belt has to be put on further back or further forward in order to align. But if the pulley grooves are just the width of the drive belt and that won't be relevant. If the pulley and motor are out of line then there must be a problem with one of them. Neither the motor has a broken or loose fixing arm or the drum has playing it due to worn bearings or a worn pulley. I have written about all the possible causes of the washing machine drum drive belt coming off in my article here Drive belt keeps coming off
