Md. wm2688hnm.
Customer complained of slow drain error code.
Of course when i got there it was working properly.
I noticed the house standpipe seemed to be full of water, so i pulled out the washer drain hose slighty to check if it were draining properly and it seemed to be draining pretty good, so i didnt take apart the pump, or the check the drain hose.
I ran a diagnostic cycle and a regular cycle with clothes in it, and it ran fine both times, no error code, no wet clothes.
Got a call back, its saying the same thing.
So, is this a pump issue? Pressure switch? Computer? Clogged stand pipe? Clogged drain hose? Crazy customer?
Thanks!!!

Supposedly the customers "cleaned" out the drain pipe, not sure what that meant, but when i pulled the drain hose out a bit and could hear it draining, it sounded fine, i even marked the drain hose so the customer knew not to push it further than that, not sure if they paid attention to that though.
Any other ideas?

If that pump filter is gunked up that in the picture above, they probably have an odor problem, too--- or soon will.  May want edumucate them on preventing odor problems:  http://appliantology...p-load-washers/

I think I see my watch in that filter!  Be sure there is enough of an air gap where the drain hose goes into the standpipe.

Filter is super clean! That was my first go to. They said it doesnt happen all the time, so im thinking weird computer thing, or something to do with the standpipe?

Ok, is there a better solution to get rid of the suds? Or just flush it out with fresh water?

I was also thinking about the airgap, when i first got there the drain hose was pushed down far in the standpipe, and i couldnt hear the water draining, but when i pulled out the hose a little i could start hearing it.

Once you've eliminated the suds as a potential issue, if the problem still remains, then this is characteristic of a drain pump failing under load:  http://www.repaircli...umber=WM2688HNM

Finally got back, and sho nuff, the drain pump was bad!

I actually removed the windings from it and separated the impeller from the housing and there was a bunch of scrud inside it!!

Installed new pump, and then the damn thing started to overfill!!!!

Wholly sh!

Blew out a couple pressure hoses and bam, back to normal!

All fixed! Im happy, the customers happy!!

Game Over!!
