ERROR CODES

Communications C E If there is any breakdown in communication between the machine controller and the motor

Errorcontroller, “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.

 

 

 

 

 

 

 

 

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

C A

If a status signal comes back from the motor controller that a current limit has been breached,

 

 

Limit

the unit will return to standby mode and display either “CA” for average current limit trip or

 

 

“CI” for instantaneous current limit trip.

 

 

or

C I

Average current trip occurs if there is a 2 second average of current draw greater than 5.55

 

 

Instantaneous

 

 

Amps at the motor windings.

 

 

Current Limit

 

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.

 

 

 

 

 

 

 

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.

 

 

 

 

 

 

 

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

L S

properly. This error code may also be used if there is a disagreement between the motor

 

 

 

 

The control should flash this error code if it cannot detect the lid switch opening and closing

 

 

 

 

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.
