Went on a call today where before I got there felt sure it needed a new drain pump.  Here's the deal:

 

Unit will drain, then stop, then start to drain again, then stop, then drain some more, etc. 

 

Customer says at some point it will give ND error code (No Drain).  Or it may eventually start spinning. 

 

Today while I was there it went through that same scenario, then after it stopped and did nothing for about 2 minutes it started to spin.

 

While draining I looked at the hose while it was sending water down the house drain and the water pressure was very strong.  There doesn't seem to be any problem with the drain. 

 

What part on this unit senses whether there is water in the tub or not?I 'm thinking this may be the problem? Is it different than the pressure switch?  The pressure switch seems to work for filling the washer.    

 

Stumped.  Please help.

 

Thanks.

Shot in the dark, but, I had one of these hateful bastards kind of with the same symptoms...sometimes drain some times not. I took the drain pump loose and found in the inlet hose, a damn quarter....the coin was to big to make it into the pump ,but just the right size to pivot around in the opening... some times on end (great pump flow), sometimes flat (blocking flow completely)....worth a look.

Thanks for the advice but the way it happened while I was there, but of course it worked too, however, it still kept trying to drain and I was there to verify that all of the water had been drained out.  It cycled the drain pump at least 6 or 7 times, took about a 2 minute break, then started spinning.  But liike I said, according to the owner, sometimes it would cycle the pump 6 or 7 times then give the ND code. 

 

When there really is a drain problem, which part tells the control that there is still water in the tub?  Would it be the pressure switch? 

 

Thanks again.

Anyone?  Remember, I was there when it was draining, there was not a drain problem.  When the drain pump came on water was pumped out wide open.  It didn't work properly while I was there.  What part tells the control board there is a drain problem, when there is a drain problem.  When there is a drain problem, how does the control board know it?  It seems to me that the part that tells the control board that there is a drain problem is the part that is bad.  I think it's telling the board there is water in the tub when there isn't. 

 

Thanks.

When it stops draining, is the pump still getting voltage?  If it is, then the pump is failing under load.  Not uncommon in these dinky little drain pumps:  http://www.repaircli...mber=MAH6700AWW
