SOURCE: Error Code F-01

Hi, After about year and half Whirlpool duet sport gave F01 error code. The technician manual is located under the lower front panel. There are three possible reasons for F0: 1) EEPROM ERROOR. Unplug a washer for two minutes. Try running it again. (Did not work for me). 2) MAIN RELAYS ERROR. The tech manual suggests replacing CCU. The following is what I did and it fixed the problem, however. Unplug the washer. Remove the top cover by removing the three screws on the back. The CCU unit is in the right bottom corner if standing in front of the washer – it has a lot of wiring. Plug in the unit. While listening to the CCU start any washing cycle. After pressing START you should hear the relay to click. If it clicks twice, within a less than a second, it has a problem. Unplug the washer. Without disconnecting any wires remove the CCU cage from the washer wall. Stand now on the right hand side of the washer in such way that the CCU cage is under your left hand. Pull the right upper corner of the CCU plastic cage (it has a tab) away from you, slide the cage to the right by about an inch, and pull the entire cage away from you. Now knock on the back side of the cage 4-5 times with a bit of force (watch “Armageddon” movie for more instructions on it). Install the CCU cage back. Plug in the unit. Try some washing cycle again. If it did not help, repeat the procedure. If it did not work again, see the following. 3) PUMP DRIVE ERROR. The tech manual suggests replacing CCU.

F01 - There may be an internal problem with the control, attempt a Hard Reset.

Hard Reset - In some cases the control can be non-functioning or may not accept activation from the control panel. To clear and restart the control follow the these steps:

* Unplug or turn the circuit breaker off for 30 seconds.
* Reconnect the unit to the power source by turning the breaker back on or plugging the unit back into the wall outlet.
* Press the Pause/Cancel/Stop button twice to clear the "PF" in the display.
* Start a short cycle to check the operation of the machine by selecting a cycle and pressing and holding the start button until the machine starts.

The F01 generally indicates a failed electronic machine control board.
This error code can sometimes be caused by a glitch or power surge through the electrical lines.
You may be able to clear this code by unplugging the washer for 5 minutes.
If the code returns after plugging the washer back in, then the electronic machine control board will need to be replaced.

The procedure for accessing and replacing this control board is shown in this image...

Be sure to unplug the washer before accessing internal components.
When you access the control board, I recommend transferring the wires from the old control board to the new replacement control board one connection at a time.
Once you have all of the wires transferred, remove the old control board and mount the new control board in the washer.
Reassemble and test the washer.

The "F01" error code indicates a communication error between the Central Control Unit (CCU) and the EEPROM onboard the CCU.
The "F01" can also be displayed if the onboard "Pump Driver" fails to activate.
Generally in order to correct this failure will require replacing the CCU.
There is no way to test and verify if the control board has failed.
The technical data sheet basically states to replace the CCU.

F21 According to Whirlpool:

"This error code indicates that drain times are longer than expected.
Is the drain hose kinked or clogged?
Make sure the drain hose is not kinked or clogged. Straighten the hose for adequate water flow. Remove any blockage from the drain hose, drainpipe or utility sink. Use the U-shaped drain hose form on the drain hose, and secure the drain hose. See the Installation Instructions for details; find them by entering your model number in the search tool below."
Also
"Are you using HE High Efficiency detergent?
Use only HE High Efficiency detergent. Using non-HE detergent, or more than the manufacturer's recommended amount of detergent, can cause excessive suds. The excess suds will slow or stop the removal of water from the washer.
Concentrated detergents labeled 2x and higher will require a small amount of detergent based on load size. Always follow the manufacturer's recommendations."
