Hi All,

First time posting. Pulling my hair out on this one.

I have been troubleshooting my dishwasher for months and replaced a couple of items: OWI sensor (performed diagnostic cycle after replacing it) and drain hose (check valve gone). Main problem was dirt and a film left on the dishes. Less of a problem with parts replaced but still not washing like it used to. Last night, ran a diagnostic cycle and then a Pots and Pans cycle with hi-temp and sani rinse with a Finish Cleanser only in the tub. This morning, the Clean LED was on but also the Sanitized LED was blinking. What I am more concerned with though is that I hear the wash pump (verified not to be the drain pump) running in the last half hour to 45 minutes of the cycle and then turns off when the cycle ends with Clean LED. The pump has been doing this since the beginning of my troubleshooting and I can't remember if it was that way when the dishwasher was running trouble free. Doesn't make sense because there is no water in the sump when it runs during this time. Between the pump running and the dishes not coming out as clean, I feel there is still a problem. Note that I have also timed a Normal cycle two days ago with the fill and drain times within spec. Cycle ran with 10 almost clean dishes for a full two hours which is excessive (should have been around 78 minutes, not 120!) per the diagnostic/troubleshooting sheet in the bottom panel. Further, it did a pre-wash, main wash and rinse and that's when the wash pump comes on with no water in the sump and just spins until the cycle ends with Clean LED on. Washing and Sensing LED's are on during the time the pump is on. Near end of cycle, the Sensing LED turns off.

Things I have done and conditions that haven't changed during the life of the dishwasher: water softener, hot water (I will check temperature tonight but never had problem with temperature and five people in the house), taken out both wash and drain pumps from sump, taken out sump, cleaned chopper and sump, pump impellers good and connected to pump shafts, removed control panel with no obvious signs of burned out components, cleaned vent, cleaned all spray arms (no dirt in ports), verified arms turn, water drains no problem, water gets very hot during hi-temp cycle, touching heating element during cycle is too hot to touch (resistance not checked).

I thought the control board might be bad but I can't determine that without replacing it and that is $250 later (I'm in Toronto, Canada area).

I am really hoping someone has an idea of what might be going on. All help is appreciated. Thank you.

What I need to confirm first is whether or not the wash pump should run (dry) in the last half hour to 45 minutes of the cycle? Is this normal?

The answer to this question will likely lead to me replacing the control board but I need to confirm first.

No that is not normal.Sometimes the water valve can let water to come in and work ok for some fills then open up electrically and then when it is suppose fill no water.This is very common just letting you know. Tech sheet below.Part number: WPW10158389

You are magic ohm: the water valve was the problem! I ran a normal cycle and it went through multiple rinse cycles until the end of the cycle and the clean LED lit. I never would have thought the solenoid on the water valve would have faulted out mid cycle like that but it makes sense that it was the problem. Thank you very, very much. If anything changes, I will let you know but you have solved my problem. Many thanks!!

This thread should be STICKY'd IMHO as I couldn't find any answers on the internet regarding the pump spinning at the end of the cycle.
