F3 Water Temperature Measurement Exceeds 85 Degrees Celsius

The water temperature is sensed at greater than 85 degrees C / 185 degrees F.

The product will abort the wash program, log the fault, report to the user, and disable the power supply.

Note: The isolation relay will be disabled. Power to the product will need to be disconnected then reconnected for it to become fully functional again.

PRIMARY ACTION

-Check the incoming water temperature is not too hot.

-Check the temperature reading in diagnostics, and if 199, ensure the power connector is properly fitted to the controller and the connector on the heater plate is correctly fitted.

SECONDARY ACTION

-Check the resistance between pins 1 and 2 of the controller power connector is about 10K at approx. 25oC / 77oF ambient room temperature.

-If not (provided the harnesses are ok and the connectors are correctly fitted), replace the heater plate (bad temperature sensor).

TERTIARY ACTION

-Check that the temperature reading in diagnostics is the same as the temperature of the water in the tub. If the tub water temperature is obviously below 85oC / 185oF, replace the controller.
