Sub-Zero & Wolf Error Code E5
Heater error
Common Causes
- 1Heating element failure
- 2Relay fault
- 3Wiring damage
Disconnect power before testing the heating element. The element operates at 240V in some Cove models. Verify voltage rating before measuring.
Step-by-Step Troubleshooting
- 1
Test the Cove heating element resistance — should read approximately 10-15 ohms; infinite reading means the element has burned out
- 2
Check the heating relay on the control board — a failed relay prevents voltage from reaching the element
- 3
Inspect the wiring connections at the heating element terminals for burn marks or loose connections
- 4
Verify the high-limit thermostat has not tripped — it cuts heater power if temperature exceeds safe limits
Pro Diagnostic Tip
Cove dishwashers use a concealed heating element in the sump for safety and aesthetics. Access requires removing the sump assembly — plan for 60-90 minutes of labor for element replacement.
