    I just pulled my MCU - the 471 resistor looked fine & read 469 ohms. It's a bugger to get the MCU out - had to disconnect the wiring harness support that clips to the frame to get the thing out. Now I'm going to check the motor windings.

    I just checked the motor winding from the cable @ the MCU. All 3 checks were 7.1 to 7.3 ohms, so I think we're OK with the motor. I had cleaned the connector at the CCU 2 weeks ago and it worked fine until now. So now I cleaned the connector at the MCU to see if this helps.

    3 pin wire came of the three pin going from the ccu to the mcu. 1-2-3 does it match the bottom or different

Mcu is responsible for the f06 fault code

Posted on Mar 24, 2008

I had a similar problem.

The duet would always return an F06 error on the spin cycle(after about 1 min after doing the drain cycle). the motor would turn during the drain cycle for about 1 second and the other cycles acted somewhat normal.

Heres the solution:

The MCU uses the tachometer of the motor(rpm sensor) during the spin cycle only. It returns F06 because it can't read the rpm's. (for some reason it doesn't use it during normal cycles)

What I found out was that a resistor, believe it or not was bad. A 0.01 cent part to fix a 1000$ machine. (I wonder how much money has been wasted on this problem ;/)

The resistor is the first resistor that enters the mcu board on the tachometer. (I put the mcu back up before I could take a picture)

To find it, trace the circuit from the back side of the board where the tachometer wires come in at(its the 2 lower ones out of the 5 black + green(ground)). One of them will lead to a via(thing that goes to other side of board) which leads to a resistor labeled 471(470 ohms). On mine it looked slightly charred at the top almost like dirt and I didn't think about it but I finally put an ohm meter across it and it read open(should have read something).

After replacing it everything seems to have been working fine. What happened was that the tachometer wasn't being able to be read and hence the spin cycle wasn't able to start.

Replacing the MCU board would have solved it too but at a cost of several hundred(a total rip off specially for a 1 min fix if you have that problem).

Took me several hours to fix it so hopefully this will same a few others time. You can repay me by not buying from whirlpool!

WHIRLPOOL DUET WASHER MODEL #WFW9600TW01 F-35 & F-28 ERROR


The F35 indicates a water level pressure sensor failure. A loose wire harness connection could be causing this problem if there is no water or suds in the tub. I recommend unplugging the washer and removing the top panel. Screws at the very back of the top panel secure it to the washer frame. Remove the screws and then pull the top panel slightly back and then up and off of the washer. The analog water level pressure sensor is shown in the first image below. The second image shows a clear picture of this component. Check the wire harness connection on this sensor. If you find a loose connection, secure the wire harness properly on the component then reassemble and test the washer. If you continue to get the F35 code, then the pressure switch will need to be replaced. I hope this helps.

also for the F-28 issue

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
