My Whirlpool Duet Steam Washer, Model # WFW 9500 TW 01 is either stuck on SUD or Error Code F35 is displayed.

It helps to have FULL make and model in such questions, but here are a few ideas

The F35 error code indicates an analog pressure sensor error. The analog pressure sensor is the component that detects water level in the washer tub. This error can usually be cleared but it will occur again if the main control board still detects a problem with the signal from the analog pressure sensor.

Pull out your washer and look on the back for a plastic sleeve with paper in it. Often these papers are materials for the repair person. If you are lucky they are what you need to solve the e51 mystery.

Hello & Welcome to FixYa

F35 error means that there is some sort of issue with the steamer electronic board and analog pressure sensor has gone bad. Check that the hose is firmly attached with the washer and is not blocked. You can also check the water level pressure switch operation. Please get back to me if you have any other questions.

Hi,
You can go to www.whirlpool.com and select Owners Center, then select Manuals and Literature. Put in the model no. and you should find one there. Click HERE for this manual.
Hope this is what you need, Please rate and comment Thank You Joe

F35 is a water level error.
The water level switch (pressure switch) has malfunctioned.

If you remove the top panel, three screws in the back, you will have access to the pressure switch.

With the tub empty, remove the vinyl hose from the switch and blow backwards through the hose to clear any restrictions.

If the fault codes return after doing this, you will likely need to replace the pressure switch.


Also - please be sure to use He soap.

Here's two links on the SUD error on a Whirlpool Duet--pretty common with these newer front load washers--try less soap, try different soap, check the pressure switch.....

I;ve had the same problem (SUD on first fill) and found this most helpful for my WFW9600TW01 Duet washer

I duplicated his actions and it cleared up my SUD/F35 error. I think running the diagnostic test multiple times flushes the sensors/sensing lines to eliminate the problem.

SUD, usually caused by using the wrong type of soap. Your soap should have the letters "HE" on front of box/bottle. SUD can also be a bad drain pump, question is, does it still have water showing in tub?

F35, is a pressure sensor # W10156252, good luck finding it, as Whirlpool has problem keeping these things in stock. They list price at $112.82. Only takes about 20 minutes to change. Research sears.com, select PARTS Direct, enter model number, click on cabinet parts, find analog pressuer switch, see if they have in stock. Or, research the net for someone that does.

Take top of washer lid off, pressure switch is located on top right rear side wall of machine.

Good luck.

HELLO.F35 IS A ERROR CODE WHICH NEEDS THE ASSISTANCE OF A WHILPOOL SERVICE AGENT.THE CONTROL BOARD MIGHT NEED TO BE REPROGRAMED BEFOR YOU CONSIDER REPLACING IT.GOODLUCK.MOHAMED
