Question about Whirlpool Duet GHW9150P Front Load Washer

I have a Whirlpool Duet washer WFW9500TW. I'm getting SUD followed a short time later by F35. Every time. Every load type. Use 'He' detergents. Always run the cleaning cycle with bleach whenever the indicator light comes on. Help!

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.

What does F35 code mean and what to do?

  • Run an empty cycle without using any detergent. Often the fault code displays when too much detergent is used and the detergent sits in the drainage system. A cycle without any detergent is often enough to clear out the buildup.
  • 2 Pull the drain hose out of the standpipe mounted to the wall behind the washing machine. Complete a visual inspection of the hose for any clogs. If you see any, remove the screw that holds the hose clamp onto the discharge pump and then force water through the drain hose with pressurized water from a garden hose. Reattach the hose and then run an empty cycle to see if the code goes away.

    I have a Whirlpool Duet Washer, washer starts and then stops code F35

    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.

    Whirlpool Duet -Sud displays and washer stops

    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.

    Start a load in my 9150 (barely one year old), and either goes to F35 or to SUD, then F35. Have to shut breaker off to get it to stop! This happens 90% of the time! Serviceman came out and said I needed...

    this washer has a provision to keep rinsing until the oversudsing condition is cleared [SUD] - this is caused by using too much detergent or the wrong kind of detergent - use only HE rated detergent, it is formulated to clean with a minimum of sudsing - why are the clothes tangled? you're overloading

    F35 Sud errors

    OK, you can't use regular Gain detergent in this washer. you will need to use the recommended (HE-High Efficiency) brand. its the only way to avoid the SUDS.
