Possible Causes
Shorted or open auxiliary valve coil, Faulty Hisense diverter motor, Wiring short to ground, Control board driver failure
How to Fix / Troubleshooting
Safety first: Disconnect power before working under the dishwasher.
- 1. Identify controlled component: Refer to the model's wiring diagram (often behind the kick plate) to see which valve or diverter is associated with E20.
- 2. Inspect wiring: Check the harness to the auxiliary valve or diverter for chafing, burns, or loose connectors.
- 3. Test coil/motor: With a multimeter, measure resistance of the valve coil or diverter motor. Replace the Hisense component if open or shorted.
- 4. Control board check: If the component is good but E20 persists, the main PCB output may be damaged and require replacement.
