I have a whirlpool duet steam washer model number wfw9500c01 keep getting suds code on display. I clean washer every month with refresh tablets or as indicated. what do i need to do to resolve this?

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.

Hello Maureen Turner,

If your model number came thru with your question... I could have looked it up AGAIN to see if

By far the biggest cause of the "suds" alarm...
is "SOME ONE" is using other than "HE" washing
agents in your HE machine...

Stop it... Read your owners manual.

This can cause serious and expensive repairs.

Troubleshooting the F35 Sud Error Code in the Whirlpool Duet Steam Washer

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.

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.

pressure switch has been a problem with these models

Needs new drain pump. About $140. Will fix F02 / SUD error. Basically the drain pumpm isn't pumping water out. about 5 minutes to replace.

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.

Our new Whirlpool Duet had the same problem after only three months of use. We contacted Whirlpool since the washer is still under warranty. The issue is a "bad pressure switch". The part number is W10156252. Service company replaced the part yesterday, and the washer is working like normal. Whirlpool nor the service company had any explanation why the part would go bad in such a short time. No charge since the washer is under warranty.

WARNING - There must be a shortageWe were initially told that the part was backordered for 2 to 3 weeks. We even tried to obtain the part through other vendors and got the same time frame. Furious with the potential of being without a brand new washer for 3 weeks, we spent many hours on the phone with Whirlpool trying to expedite the part. After some strong encouragement and moving the issue up the chain of customer service, Whirlpool agreed to pull a part from the factory inventory where the washers are built. The only problem is that nobody could tell us when, or if, the new part would be shipped. Suddenly, the part just arrived by FedEx at our house. In all, our washer was inoperable for 1 week. Be persistent. They will tell you over and over there is nothing they can do.

If you negotiate well, Whirlpool will extend your factory warranty for an additional year.
