Whirlpool

Unit is about 5 years old

Will fill with water, not run wash, and drain on all cycles. No error codes

I replaced main control board and all was good for three wash cycles and now the issue is back along with the heating element is on even though the heat put us not pressed or illuminated. Again no fault codes

Could it be a faulty main control board?

That's what it sounds like. What's the part number of the new control and where did you get it?

I have reached out to the company. Did not purchase on EBay or Amazon. Probably won’t hear back until Monday. Thanks for your insight.

Well, I replaced the control board again. It is a certified Whirlpool part. All was good but now the issue has returned….fills with water, dispenses detergent and drains but no wash cycle. No error codes….any idea what else may be going on?

Does the heater come on like in your first post? Check all your connections. Make sure they are on tight. Check for 120 VAC at the wash motor.
