Replaced control ran fine 3 times, now it is stopping

Hello
Replace the sump assembly, which contains the heater, ntc sensor, etc. It is likely not sensing a heat rise if one is present. It will stop when this happens.The heater is in the motor, part # 00669135. Also see if you can bring up fault code e24 or e25 control board monitors current between wash motor and drain pump also check the drain flap it is down were the drain hose goes into the sump. had a few we removed the little flapper.
