Whirlpool Dishwasher Model WDT780SAEM1 Stops Mid Cycle

[Jpsbgt]

Unit is 5 years old. Starts cycle, fills with water, cycle starts normally but just stops after a few moments. This happens on all settings. Diagnostic shows F6/E4. No leaks are visible. Checked supply line, checked drain line. Unplugged unit to reset but still have same issue. Removed unit from cabinet, tilting it to remove all water. Please advise…Jack

Does it fill with water, and drain properly? 
Very possible that the wash motor is malfunctioning. I’ve run into a slew of these where the wash pump either draws too much current and the control board cuts off power to it, or the pump’s motor ohms open. I’d ohm-out the pump (light blue wires) to start.

Thanks! I have determined that the wash motor pump is bad. I ordered a clone for $59.00 delivered, WP wants $250.00 for the pump which can fail in less then a year, bad design of motor and it’s graphite bearing . Will update the outcome.

Changing wash motor when you have a leak sensor error?

Good luck with that. 
 

You need to determine why leak sensor is being activated(source of leak)

I guess you think you know it all right ? Absolutely no leaks present. Replacement clone wash motor cured the issue. And I even managed to replace just the motor portion of the pump. Most don’t realize that it is not necessary to swap out the entire assembly. $59.00 for the part. Afterwards the F6 E4 code was gone.
