WHIRLPOOL FAULT CODES

Whirlpool Calypso Automatic Washer Fault Codes
Failure Code Fault Code Description Solution
PF Power failure "PF" flashes if the washer loses power during a running cycle. The washer does not flash "PF" when it is first plugged in.

Press START to continue the cycle from the moment that power was lost.

OR

Press STOP/CANCEL to clear the display and completely cancel the cycle.
FL Flood condition "FL" flashes if any overfill condition occurs. This condition occurs when excessive water in the tub causes the overfill switch to trip. The control must realize that the trip was due to an overfill condition instead of a suds lock condition in order for "FL" to be displayed.

With an overfill condition, the beeper repeats a warning every 10 seconds with no time out. The pump is cycled in drain mode for 30 seconds on, 30 seconds off until the overfill switch resets or power is discontinued to the unit.

Press STOP/CANCEL to clear the display.
Er Processor reset error This error code is displayed if the control failed to save cycle information during a power failure. This does not generate an error code beep.

Press STOP/CANCEL to clear the display.
LF Long fill If the water fill time exceeds ten minutes, the water valves are turned off and "LF" is flashed.

Press STOP/CANCEL to clear the display.
CE 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 coating 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.
Ld Long drain "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.
CA
or
CI
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 windings.

This may signify problems with the drive motor, thermal protector or motor controller. Overloading the unit may cause this problem.

Press STOP/CANCEL to clear the display.
ob Off balance If the motor controller detects an unrecoverable off-balance condition, the machine controller 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 you to view and redistribute the load.

Press STOP/CANCEL to clear the display.
Sr 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.
Flashing display time Open lid If the lid opens while the unit is in running mode, time remaining will flash in the display.

Close the lid and press START to continue with the cycle.
SL Suds lock The motor controller senses a suds lock condition by analyzing the current draw on the drive motor. If a potential suds lock is detected, the control tries up to 3 times to clean out the unit with a mini-cycle.

"SL" is displayed if suds are detected but the unit is unable to clean out suds. This may indicate a bad pump, an extra heavy load, excessive detergent or excessive suds.

Press STOP/CANCEL to clear the display.
