Communications
Error
If there is any breakdown in communication between the machine controller and the motor
controller, “CE” flashes and the unit beeps once.
Some common causes of “CE” errors include:
•
Conformal coating on serial communications pins between the machine controller
and motor controller. After disconnecting power to the unit, try scraping this coat-
ing off the pins.
•
Check the resistance values between the serial communications pins with the
connectors in place. Make sure the harness does not have a bad connection.
•
Check the quick disconnect at the motor terminal. The drive motor must be hooked
up properly or a “CE” error will occur.
•
Drive motor thermal protector has opened.
•
Motor controller is not powered or fuse has opened. Replace motor controller.
Press STOP/CANCEL to clear the display.
Off Balance
o b
If the motor controller detects an unrecoverable off-balance condition, the machine control-
ler will shut down and display an “ob” for off balance.
The lid switch must be opened at least once before restarting the cycle, if this condition
occurs. Opening the lid will allow the customer to view and redistribute the load.
Press STOP/CANCEL to clear the display.
Long Drain
L d
“Ld” flashes if it takes longer than 5 minutes to pump out water to a point where the operating
pressure switch resets.
Press STOP/CANCEL to clear the display.
Average Current
Limit
or
Instantaneous
Current Limit
If a status signal comes back from the motor controller that a current limit has been breached,
the unit will return to standby mode and display either “CA” for average current limit trip or
“CI” for instantaneous current limit trip.
Average current trip occurs if there is a 2 second average of current draw greater than 5.55
Amps at the motor windings.
Instantaneous current trip occurs if there is a spike of 26 Amps instantly at the motor wind-
ings.
This may signify problems with the drive motor, thermal protector or motor controller. Over-
loading the unit may cause this problem.
Press STOP/CANCEL to clear the display.
Stuck Relay
S r
“Sr” signifies a failure of the relay in the closed position. With this failure, power to the motor
controller cannot be turned off by the machine controller.
The machine control board may have a bad relay and may need to be replaced. Check pins
1 and 5 of P16 of the machine controller and pins 1 and 2 of P1 of the motor controller. This
should have AC line voltage when the motor controller is powered.
Press STOP/CANCEL to clear the display.
Lid Switch Error
The control should flash this error code if it cannot detect the lid switch opening and closing
properly. This error code may also be used if there is a disagreement between the motor
and machine controllers on the state of the lid switch. The control should not allow the unit
to run in this condition.
This code will also appear if the user presses the START key while the lid is open.
Open the lid or press STOP/CANCEL to clear the display.
