We got this unit with our house and it's been fine, occasionally unbalancing, and a few days ago suddenly developed a loud grinding noise during agitation. This seemed to be associated with less or no agitation as well. The unit spins absolutely fine, and drains, no extra noise. I pulled apart the agitator, and found that the washer hub seal nut had disintegrated quite a bit and there was wear on the lower agitator where that pushes on it. But the inner gear teeth on the lower agitator look fine. I ran it with the agitator off and it still grinds, but the agitator seems to move as it should.

I flipped it up and looked at the washer pulley and thrust bearing, but that all seemed okay.

Questions: obviously, what's going on? And specifically, if the washer pumps and spins just fine, it must not be the motor? Is it something further inside? I can provide pics of what I did but I am not sure I've gotten down to the actual issue.

I'm considering doing this myself rather than buying a new washer because these seem to be well-regarded. Any thoughts on this? Shoudl I just replace?

Its possibly the drain pump pulley bearing that has gone bad.

What I do is tilt the washer back and remove the belt from the pulleys, then turn the drain pump pulley by hand and see if it turns smooth both ways, if not you will need a new drain pump, and if it burned the plastic motor pulley you need to replace that too along with a new belt.

The serial number of your washer determines which drain pump your model takes.

If the serial number of your washer starts with 18 or lower, here's the drain pump for your model you can order:
WP35-6465 Drain Pump Assembly


If the serial number of your washer starts with 19 or higher, here's the drain pump for your model you can order:
WP35-6780 Washer Drain Pump Assembly


Let us know what you find.

I'll check this. But would the pump pulley be doing anything when the washer is washing/agitating? The noise happens THEN, but not when the washer is pumping water out. It does that fine.

Yes, on this model the drain pump pulley turns both ways when its agitating it turns one way, then in drain/spin it turns the other way. So that's how it can make the grinding noise while its agitating.:)

Yes, keep us posted.

Ok, did you turn the motor pulley and transmission pulley both ways too? Any grinding on those? If not, then you will need to make a video of this grinding noise you are hearing and upload the video hear so we can hear it too.

Here's the grinding sound:

Here's the washing spinning fine:

I'll get in there and crank things around again. I don't think the motor had any problems turning.

Yes, I heard it. Thanks!

The grinding noise is coming from the transmission.

Here's the transmission for your model:
Transmission 35-6615


You can buy a new Maytag washer for a little more than the cost alone of the transmission.

Jake, thanks so much for your help on this. Not the outcome I was hoping for, in terns of DIY success, but better than spending a bunch of time trying to fix it unsuccessfully.

I didn't say fix it unsuccessfully, It can be fixed successfully if you want to pour over $400 into this machine to fix it.:)

But that doesn't make sense, as you can buy a new machine for $500-$600.
