Jane for Model Number KDTE104ESS2 3 year old dishwasher (KDTE104ESS2) suddenly not washing very well (food still left on dishes) and doesn't consistently dry when "heat dry" is selected. Sometimes Detergent pod is left half melted in the dispenser. Sometimes the dishes are hot and dry at end of cycle and sometimes they are still wet. I've tried running hot water prior to wash but this doesn't help. Our hot water is extremely hot at tap. I've tried letting the water run prior to cycle but it doesn't help. I've had one repair tech tell me it needs a new controller and another tell me it needs a new motor. Confusing. Receiving an error code 7-1 but neither tech seems to cares about that. Thank you.
Answer Hello Jane, the code refers to the control board either detecting the heater not heating the water or has disabled the heater circuit for another found problem, a circulating pump problem would cause it also it would explain the poor cleaning. Once the dishwater fills with water the circuiting pump should start, the complete pump/sump assembly is part AP6023350. Read More... Answered by AppliancePartsPros.com | Thursday, June 4, 2020
