I am getting iintermittent F02 long drain error codes. Following direction, I checked the trap, it was clear and the pump input hose did not feel like there was anything in it I replaced the trap and the machine ran fine for a few loads. When it happend again, I noticed that the input hose had collapsed just before the pump /trap inlet. This tells me that the pump is fine, sice it can pull a vaccum and colapse the hose. I have ordered a new tub to pump hose, assuming that the colappsing is due to age. Is there anything else I should look at?

I have checked the trap: clean. Stuck my finger into the pump and I was able to rotate it with relative ease so it is not clogged. The drain hose is not kinked. I have squeezed the tub to pump hose and felt no blockage in the hose. I have ordered a new tub to pump hose because I don't trust it's integerity because of age and being colapsed. The problem is intermittent, so it could be a 'floating' piece of debris in the pressure switch hose. I will blow it out as suggested. Tha machine has not moved since we bought it, and has worked flawsly until recently, so I doubt it is kinked. Thanks for the quick reply and the suggestion of blowing out the hose, rather than a blanket replace switch and hose.

I found the problem! After removing the tub to pump hose and finding nothing it it, I stuck my hand up the tub opening and pulled out a very wet, very chewed up neoprene knee brace that must of gotten inadvertently put in the washer that found it's way overboard and was to big to work it's way down the hose. It partially blocked the hole enough to cause the pump to pull a vacuum and collapse the hose. I replaced the hose and redid all of the clamps with standard hose clamps. Problem solved!
