Called to upscale home regarding above dishwasher.
Found, inlet/drain error and continuously beeping. Ran diagnostic and found the heater relay error and softener sensor error
Heard the hum of the drain pump as it attempted to pump out the dishwasher without pumping out anything and no water was entering the wash cavity.
I know the dishwasher runs a customary initial drain prior to taking in any water. No hum or vibration at the water proof inlet area, I looked at the screens on the water proof and they were A OK. Wash cavity filter screens were clear. Nothing jamming the drain hose.
Replaced the drain pump, water proof system, and heater relay.
Bingo Bango Bongo, all is right.
Respect and thanks always. I used the service manual provided herein as a guide.
