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. 25
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 85
F4 Element Has Been On Too Long (About 4 Hours) And Water Has Not Reached Required
Temperature
The element has been on too long (about 3 hours) and the water has not reached the required temperature.
The product will abort the wash program, log the fault and report to the user.
PRIMARY ACTION
- Check that the controller power connector and the heater plate connectors are properly fitted and the harness is
not damaged.
- Check the resistance between pins 1 and 2 of heater plate PCB, and if open circuit, replace the heater plate.
SECONDARY ACTION
- Check the resistance between pins 1 and 2 of the controller power connector is about 10K at approx. 25
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
- Replace the controller.
F5 Lid Motor Current(s) Too High During Start
Lid actuator is jammed up or down.
The product will abort the wash program, log the fault and report to the user.
PRIMARY ACTION
- Check for dishes, cutlery or cups and glasses preventing lid from closing.
- Check the lid actuators in diagnostics.
- Check the yokes are moving freely and are not jammed at the front or the rear (physical inspection).
SECONDARY ACTION
- Replace the lid actuators.
TERTIARY ACTION
- Replace the controller.
C / 185 F, replace the controller.
