Whirlpool Duet -Sud displays and washer stops

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.

if its a Kenmore model then this message says that the button control board has lost sight of the main control board , but its been my experience that this maybe able to be reset and it may never come back or it will not reset and the control board will need replaced (50/50)


cycling power may reset this

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

Unfortunately F06 E02 is a very bad error. It means you have an interface communication error. That means that the main control board isn't communicating with the front interface control board. You can pull the washer out and remove the 3 screws coming in from the back of the top panel. Next, the top panel will pull straight back, up, and off. Now check all the wire connections between the two control board and make sure they are all secure. If everything looks good, then the interface control board will need to be ordered and replaced.
Here is a link to the part.

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.

although this information is for a different model number it should help you troubleshoot your machine as all Duet models have basically the same internal components

Hi dear.I may have solution for the SUD error.You can give it a go.But I do not know any thing about F35 one
The motor control unit senses a suds lock condition by analyzing the current draw on the drive motor. If “Sud” is displayed a potential suds lock is detected. This may signify a bad pump, an extra heavy load, excessive detergent, or excessive suds.

Potential Causes

• If too much detergent was used, run the unit through a Rinse/ Spin cycle then a Normal cycle without adding any detergent. This should clear the unit of the excess detergent.
• Check the drain hose and make sure it is not plugged or kinked
• Check Wire Harness connections to the Drain Pump, Pressure Switch, and Central Control Unit (CCU)
• Check / Clean Drain Pump Filter of foreign objects
• Check Drain Pump
• Check the Pressure Switch
• Check CCU

Replace failed component.

As it says run couple of rine cycles it should get back to normal.I hope that helps you.Thanks.

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.....

if it is less than one year old call for service it should be covered. if not take the kick panel off and locate the tech sheet it is either in the kick panel or in the cabinet to the right. it will give you a list of error codes find out what it means and let me know thanks

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.
