How to Fix Heavy + Delicate blinking Error

1. DISCONNECT POWER. Shut off the circuit breaker for the dishwasher.
2. PULL OUT THE DISHWASHER. Disconnect water and drain lines and pull the unit out from under the counter.
3. TEST THE THERMISTOR. Locate the thermistor (DD32-00005A) in the sump assembly. Disconnect its wires and test its resistance with a multimeter. A reading outside the manufacturer’s specified range indicates it’s faulty and needs replacement. [2]
4. TEST THE HEATING ELEMENT. The heating element (DD47-00060A) is a metal tube at the bottom of the tub. Disconnect its terminals and test for continuity with a multimeter. A reading of ‘OL’ or infinite resistance means the element is burned out.
5. REPLACE FAULTY PARTS. Replace either the thermistor or the heating element based on your test results. The heating element is held by two nuts; undo them and pull the old element out, then install the new one with its rubber seals.
6. REASSEMBLE AND TEST. Reconnect all components and wiring, slide the dishwasher back into place, and restore power to test.
