FIXED MVWB855DC4 Grinding noise at end of cycle.

I have a barely 2 year old Maytag washer that has started to make noise. It seems like it might be a loud grinding noise. The noise appears to happen at the end of cycle when the tub is spinning. Specifically when the tub is supposed to be coming to a stop. Almost like it would be trying to apply a brake but the brake fails (i know these models don't have a specific brake assembly). Normally the spin would slow down pretty quickly and then go do "done" and unlock the lid. When this problem occurs, the spin will still be going pretty fast, goes to "done" and unlocks the lid. So you then can open the lid while the tub is still spinning.

When testing, it seems really light or no load will not reproduce the problem. Its only when its normally loaded or fully loaded (fully loaded per Maytag).

I don't know if this could be the clutch or maybe even the gear case, but when it makes the noise it makes everyone in the house concerned.

Any help in diagnosing this would be greatly appreciated. Here is a link to a video that shows the noise. It was too large to upload here.

Sounds like either a bad transmission bearing or clutch. Also that lid should not unlock until the spin basket stops completely. So you may have 2 problems going on.

First check to see what error code you get, I'm attaching your tech data sheet below. Page 2 ACTIVATING SERVICE DIAGNOSTIC MODE

There are no current codes stored. I just did a light wash and had the problem occur and checked right after it was done.

Update: I believe this is fixed. I tipped the unit back and found that the Motor Bolt (Torx) holding the Motor Cover was extremely loose. I tightened it up and ran a cycle without issue. It even slowed down the tub as expected at the end of the cycle. If it happens again, I will refresh the blue locktite on the bolt and tighten it up again.

Excellent, good find.

Here's your rotor bolt: W10752189

Yes I agree, if it comes loose again apply loctite blue 242 threadlocker and re-tighten that bolt to keep it from loosening up again.

Here it is: Threadlockers from Loctite Products | Threadlocking / Mechanical Gasketing | Loctite Adhesives
