Possible Causes
Open or shorted NTC sensor, Damaged sensor wiring harness, Sensor dislodged from tank well, Control board input fault
How to Fix / Troubleshooting
Safety first: Disconnect power and allow the tank to cool before touching any sensor or tank fittings.
- Locate the sensor: Find the wash tank temperature probe (NTC) threaded or clipped into the tank wall or well.
- Inspect wiring: Check the harness from the sensor to the control board for cuts, abrasions, or loose connectors. Reseat connectors firmly.
- Check sensor seating: Ensure the sensor is fully inserted into its well and making good thermal contact with the tank. Tighten if loose.
- Replace sensor if faulty: If the sensor is physically damaged or tests open/shorted (qualified users only), replace it with a Hobart-compatible NTC probe.
- Control board check: If a known-good sensor still triggers E11, the control board input may be defective and require professional replacement.
