E5. TANK OVERHEATING:
Cause: The wash-tank temperature exceeded 90°C.
Checks:
1. Check the sensor integrity. Replace if needed.
2. Circuit board failure. Change the circuit board.
E6. TANK DRAINING FAIL.:
Cause: The draining of the wash-tank was not completed within the maximum
foreseen time limit.
Checks:
1. Check if the drain pipe is clogged.
2. Check if the drain pump is working properly.
3. Circuit board failure. Change the circuit board.
E8. TANK SAFETY THERMOSTAT:
Cause: The tank safety thermostat is tripped.
Checks:
1. Reactivate the thermostat.
2. Check the circuit board electrical connection.
3. Circuit board failure. Change the circuit board.
Z4. TANK SENSOR FAILURE:
Cause: The circuit board does not detect the pressure-switch or the pressure-switch
failed.
Checks:
1. Check the electrical connection between circuit board and sensor. Restore the
connection.
2. Pressure-switch failure. Replace if needed.
3. Circuit board failure. Change the circuit board.
Z5. TANK HIGH LEVEL:
Cause: The tank pressure-switch detects an excessively high level of water in the
tank.
Checks:
1. Drain and load again the wash-tank.
2. Pressure-switch failure. Replace if needed.
Z6. TANK LOW LEVEL:
Cause: The tank pressure-switch detects a too low level of water in the tank.
Checks:
1. Drain and load again the tank.
2. Pressure-switch failure. Replace if needed.
