1.) Can anything other than the wash pump cause this? could it be a false alarm? clogged?
2.) is there a service manual available showing the replacement steps for the wash pump?
Hi John. You can take and fill the tub with cold water up to the element level and press cancel or drain. This will flush the motor from suds. Do this over and over until it is clear of any suds. This may flush out dirty , sudsy water from the sensor infra-red area. The e-03 code is the Wash motor or wash motor hall sensor failure. The wash motor is part # [AP4452650]. The sensor is part # [AP3580342]. Check for suds in tub. Check for syphoning or no fill conditions. Check wiring between motor and Main Control Board. If correct, replace wash
motor. If error still exist, replace Main Control Board. Thank You.
