This indicates that the pressure switch or also called the analog pressure sensor has failed. First you will need to remove the top lid. Usually 2 or 3 screws on the back and the top comes right off. The pressure switch has a clear hose and a clump of wires going to it. Then unplug the hose and blow thru it it should be clear. Check the hose for leaks or obstructions. Also in the back of the washer on the left hand side is a air dome this is where it gets it pressure reading from, make sure it is not obstructed. If all is clear the pressure switch will need to be replaced. For help accessing the pressure switch try this link http://appliancehelponline.com/washerpressureswitch.html also if you need diagrams or illustrations of your particular model.

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.

Whirlpool duet wfw9600ta01 with the common "suds/F35" error code. Yes......we've been using the right soap. suds starts one minute into cycle followed by the F35 code immediately after the suds cycle...


WARNING: THIS WRITE-UP IS COMPLETELY MY OPINION BASED ON MY EXPERIMENTATION WITH THE EQUIPMENT. TRY ANY OF IT AT YOUR OWN RISK. YOU WILL BE SOLELY RESPONSIBLE FOR ALL THE CONSEQUENCES (GOOD OR BAD EITHER WAY) THAT YOU MAY REAP FROM THE MACHINE YOU WORK ON.


I made the biggest mistake of taking the whirpool WFW9600TA01 from US to India - I had been totally frustrated with the SUDS/F35 issue, absolutely as explained in the question above.


I started as a novice but feel very confident to write this solution now. There are several areas that could cause this problem. Fundamentally, as the water fills the tub, the pressure form the pressure switch is sensed. If the value is not in line with what is programmed, you get this error. This deviation in pressure value can be caused by any of the below reasons.


First and foremost thing I would do is remove (disassemble - note very carefully the assembly and the position before disassembling. You will need to reassemble in the exact same way in the exact same position) and clean all the pipes, hoses and connectors


Details:

The problem could occur because of:

1. True suds formation due to wrong soap usage (pretty often the problem) - Solution for this? - use a lot of vinegar and a few "risnse and spin" cycles with out any clothes in the washer


2. The pressure switch could have gone bad. Solution - replace the pressure switch (I would do this the last though)


3. There could be dirt collected at the water inlet. Solution remove the water inlet and clean the cup shaped strainer


4. Your outlet/drain pump (the one that pumps the water out of the washer into the drain) may have worn out, there by not draining out all the water. This will leave residual water impacting the next run. Solution replace the pump assembly


5. There may be particle collection such as coins pens, small pins etc in the darn pump inlet strainer causing the drain pump to not work properly and in turn causing SUDS/F35. Solution - remove the front of the drain pump inlet and remove the particles and restart.


6. There is a conical shaped connector connecting the outlet of the tub to the inlet of the drain pump. At one side of this connector (the broader side connecting to the tub) there is a plastic ball in it. If the ball is punctured, water may have collected in it causing it to weigh more than what it is supposed to. When the drain pump runs, the weight of this ball may counter act to not allow proper draining of the water. This residual accumulation of the water will cause SUDS/F35 in the next cycle. Solution - replace that flexible connector. Atleast drain the water from the front at the drain pump inlet, if you want the washer to work for that cycle.


7. There is a small white plastic tube at the back which runs a black tube to the pressure swtich. The assembly is pretty interesting. It is a simple insertion with the air tightness being achieved by a simple rubber gasket covering the insertable part (do not know why the design is such). After a few washes due to the vibration generated by the tub during wash, this gasket can move causing air leaks. Such air leaks do not cause any issue to the current run, but will result in a SUDS/F35 in the next run. It will remain so for al the next runs unless it is re-inserted properly. Solution for this? every time open the rear and make sure the plastic white part is pushed in well.


8. There are other reasons like the main control circulatory / mother board could have gone bad etc. You can figure if this is the problem by running the diagnostic tests for the most part - there is a good chance that only a certified technician can tell you. Solution - replace the mother board (quite stupid huh!!)


9. Finally, the steamer assembly could have gone bad - Although the manual says this, I cannot quite figure out how this would affect the pressure buildup in the tub - I do not know what to do. More than likely if you invite a technician, the person might ask you to replace this assembly.


Try everything - the net effect should be that you have plugged all air leaks. I know some expect to see water leaks at place where air leak exists. That may not be true at all. Good luck with everything.

Code f35 and sud on washer machine/whirlpool duet front loader


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.

Sud and f35 error in my kenmore elite h5 steam washer. The washer do not wash the cloth and flash F35.


I got the f35 and suds code repeatedly and my clothes weren't washed, I ordered from Sears the analog pressure switch that regulates the water coming into the washer and the codes went away, the part is esitmately $125.00 including shipping but you have to order from the Sears parts department.If you print a diagram of the washer it is #38 in the diagram and is easy to replace. You can install it yourself and as a female I did not call service to do it.

F35 Message on Brand New Washer


suds is determined using the level sw located on top right rear side. remove top cover to see. most letter codes do convert to a f code. most common reason for suds error is use of standard detergent or too much detergent. running a empty load of fabric softener can clean the system. or rinse/spin with nothing. other common problem is this is a whirlpool product.
