How to Fix 7-1 Error

1. Disconnect the dishwasher from power.
2. Remove the lower access panels to get to the components under the tub.

4. If the thermostat is good, test the heating element for continuity (should be 10-30 ohms). If the element is open or shorted, replace it.
5. Check wiring between the thermostat, element, and control board for damage. If all components and wiring are good, the control board has a faulty relay and must be replaced.
