Mother-in law paid appliance repair company to fix this dishwasher. They replaced main circuit board at bottom of dishwasher. Same issue happened again. I looked into this and found some diagnostic steps to follow. After testing I concluded issue pointing to logic board at top of door of dishwasher. Found the part at AppliancePartsPros. Installed the board in about an hour. Note- there are "jumpers" on the logic board that need to be in proper positions based on your model dishwasher, part came with instructions with those settings. Success ! Dishwasher working
