Found Dishwasher wash element to be shorted to ground. Checked wires down to element, okay, will order parts needed. 1-9-19 Removed faulty wash element and installed new wash element and gasket, also installed new plug above element. Filled machine and ran, tested amp draw on element, okay. Both wash and prewash pumps sound very bad, found them to be going backwards, switched wires so they are going in correct direction, pumps are much quieter now and have more pressure. Found rinse tank element bowed up out of tank, adjusted the best I could - still out a bit, recommend new element. Drain valve for rinse tank is buzzing loudly, also recommended new drain valve. Ran and tested temps, all okay.
