Service Mode - Error Codes
Loose Belt
• This error code is triggered by feedback from the motor Hall sensor.
• If the control detects excessive motor speed from the Hall sensor either due to a loose belt or tub nut,
this code will be entered into memory.
• The washer will still operate and this code will not be displayed to the consumer.
Blocked Motor
• This error code is triggered by feedback from the motor Hall sensor.
• If the control does not receive pulses from the motor Hall sensor, this code will be entered into memory.
• The washer will enter a pause state and the user can attempt to restart the cycle.
• This code will not be displayed to the consumer.
Filling Timeout
• This error code is triggered by feedback from the pressure switch.
• If the control does not receive a change of pressure from the pressure switch within 3 minutes, this code
will be entered into memory.
• The washer will enter a pause state and the user can attempt to restart the cycle.
• This code will not be displayed to the consumer.
• This can be caused by water valves turned off, pressure switch failure, siphoning or problems with the
pressure switch wiring – hose or tub dome.
Overfl ow
• This error code happens when there is a water level detected that is higher than the expected maximum
fi ll. When this failure is present, the control doesn't respond to the user until the control exits from this
failure due to a normal water level. The water valves are turned off and the drain pump is activated.
• This failure mode is saved in memory but the control doesn't display an alert to the user.
• This can be caused by failure of the water valves (jammed open) or the pressure switch.
Pump Timeout
• This failure happens when the timeout is reached for the drain pump time to reach the minimum water
level, after 4.25 minutes of pumping and the water level minimum is not reached. After a maximum of 3
attempts to resume the cycle, the control goes to Idle State, the control stores this code in memory.
