ERROR CODE F01
The pump driver fails to activate/One of the main relays is not working properly/
A communication error between the Central Control Unit (CCU) and the EEPROM
onboard the CCU occurred.
Check for loose power outlet. A loose power plug in the wall can create
line noise and issues.
- Check if washer is on a dedicated circuit. Other devices on same circuit
can create line noise and cause this issue.
- Unplug washer or disconnect power.
- Make sure that wire harness connections from the CCU are not broken or with wires
detached, and that connector internal pins are visible.
- Make sure all green wires (ground harness system) are not broken or detached.
- Make sure the two ground switches are pressed correctly by the toe and rear panels.
- Make sure all connectors are fully seated.
- Plug in washer or reconnect power.
- Check for power going to Central Control Unit (CCU) by listening for a click in the
CCU when unit is plugged in washer or when reconnecting power.
If no click is heard, replace the CCU. Here is the part to order.

SOURCE: F-01 ERROR CODE ON WHIRLPOOL
take the front panel off the bottom and the error code manual is inside. Mine says a ccu replacement for the F-01 code. Yours should be on warranty if it is brand new.

First check your washer plug to see if the connections are tightly
screwed. Next check your filter if you haven't for long.
Remove the 3 screws at the bottom of the front panel under the washer door. Your filter door will be light brown. If you find a hose there it is to drain out excess water (water that could not be drained by your pump) After you hv drained unscrew the cap and remove all the junk inside. Have a large plastic bag to catch junk and water. Refit carefully after cleaning out. If not solved, something shd be blocking your pump, check this out
How abt a nice rating for the free help? Thnks

This advice is for Whirlpool Duet and Kenmore Elite model FRONT LOADERS displaying the "F24" Error Code. Some of the error codes on these model washers can be erroneous, however. The first step in troubleshooting any error code is to simply unplug the washer for AT LEAST 30 minutes in an attempt to reset the Central Control Unit (CCU). This is the main "brain" of the washing machine. If the error code reappears following a CCU reset, then you have a genuine problem.
"F24" is an indication of a water temperature sensor (NTC) error, or Heating Circuit failure. Check the Water Temperature Sensor and check connections to the Water Temperature Sensor.
To access, you will have to UNPLUG your washer and remove the lower access panel under the door. The panel comes off by removing the screws under the bottom edge. HINT: If you place a 2 x 4 under the front feet of the washer, it will make access to the screws much easier. If the panel sticks, a tap on the sides will knock it free. The panel will drop down then come off. The sensor (NTC) is located at the base of the wash tub in the front on the heating element. This will be a small square shaped plug between the heating element terminals. Make sure this plug is secure and not loose or unplugged. It is common for the connector plug to come loose due to vibration. If the plug is intact, check the contacts for corrosion. If everything appears as it should, then unplug the wire harness and take a resistance check. Readings will be as follows:
Temperature Meter Reading
32°F (0°C) 35.9 K ohms
86°F (30°C) 9.7 K ohms
104°F (40°C) 6.6 K ohms
122°F (50°C) 4.6 K ohms
140°F (60°C) 3.2 K ohms
158°F (70°C) 2.3 K ohms
203°F (95°C) 1 K ohms
Roughly...around 9K ohms at room temperature if I'm reading the chart correctly. Take readings as listed and also double check the connector to make sure it is not oxidized. Try cleaning the plug and reconnecting to see if the error code goes away. If not, you will probably have to replace the sensor. If the sensor checks good, take a reading across the heating element terminals. It should indicate about 15 ohms.
Lastly, remove the washer top panel by removing the three screws holding the panel in place in the rear. Once the screws are removed, slide the panel back then off. Locate the Central Control Unit (CCU) directly behind the wash tub. Take a resistance check at the Heating Element Solenoid by removing connector 9 from the CCU (this is the second connector from the RIGHT as facing from the front). A reading across test points 1 & 2 should also read 15 ohms.

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.

The F33 error code indicates a pump drive system error. If the pump ohms out correctly & the harness is secure I recommend replacing the CCU (central control unit).
Please see the following image provided for instructions.
Remember to disconnect power to the washer before attempting access.
