you'll need to call someone in on this one,boards are very expensive and like it says it names both the ccu and mcu boards or the motor,if you call say whirlpool they might give you the part but you pay for labor and they will have the boards on the truck,the guy will replace one board at a time to see what one is bad,not like the older machines that you can check the parts with a meter.good luck

F33 error code indicates a pump drive system error.

If the pump ohms out correctly and the harness is secure and working fine, I recommend replacing the CCU (central control unit).

Good luck.

Hi, F70 error code indicates a "heartbeat" communication error between the various electronic boards inside the washer and the consensus seems to be the most likely culprit is the Motor Control Unit (MCU) board which needs to be replaced.

Hi,

The F33 code is a pump failure code. The control unit is not measuring the proper amp draw on the pump during pump out. Remove lower panel and unplug then replug in the pump 2 or 3 times to remove any corrosion. While your down there, take the front of the pump off to check for any blockages.BE SURE TO UNPLUG YOUR WASHER WHILE SERVICING!

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

replace the mother board and you should be ok

Hello there
If after 30 seconds the control does not detect water entering machine, the valves will be turned off and the error code will be displayed.
OR
If the control has turned the water valves on, and after 8 minutes, the flow sensor has detected 10.5 gallons of water passing through it, but has not detected the pressure switch trip, the valves will be turned off, and the error code will flash.

Press PAUSE/CANCEL twice to clear the display.

Possible Causes / Procedure

1. Check for crack or holes in the washer tub and pressure switch hose.
2. Replace components if necessary.

This is a problem I've seen before, or something similar. I think you've got a bad connection on the neutral wire. Either in the plug or at the panel. Have electrician check the neutral wire back to the panel from the plug.

the fault code indicates that your main data cable from the controller to the motor has miss-comunicated: unplug the washer wait about 30 minutes then plug it back in and, let me know if the code clears

The code is for either the MCU (Motor Control Unit ) or the CCU(Microcomputer Machine Control Unit), U probably need to rplace one of them

Good luck

Be very careful on this one. It is a door lock code or main control board. Need more info.
