My washer is giving me a F35 on the screen and not working. I can hear her trying to start but after a while the F 35 shows up and I have to unplug her in order for the lock to release and the machine to shut off. I purchased the machine in April 2008.

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.

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. This error code can be caused by a problem with the air pressure tube between the bottom of the washer tub and the analog pressure sensor. If you are able to unplug the washer and check this air pressure tube, you may be able to resolve this problem. The analog pressure sensor can be accessed by pulling off the top panel of your washer. Remove the screws at the very back of the top panel and then pull it back slightly and then up and off of the washer. The analog pressure sensor is Key 38 in the first image below. With the washer unplugged, check the connection of the air pressure tube to this component. Check the entire air tube down to its connection to the bottom of the washer tub. You will likely need to remove the back panel of the washer to check the entire air pressure tube. If you find a kink, tear, hose or loose connection in the air pressure tube, then this is the likely cause of your F35 error code. If the air pressure tube appears to be okay, then you will likely need to replace the analog pressure sensor. If the problem still exists after replacing this component, then the main electronic control board for the washer will need to be replaced. If you are not completely confident in your technical ability to safely access and check these components, I recommend calling a service technician to diagnose and repair the washer.

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.

Try this one to remove the error display f35 and f28

Press Pause/Cancel twice.

If Pause/Cancel does not work:

1. Unplug washer or disconnect power for one minute.
2. Plug in washer or reconnect power.
3. Re-select the cycle and press Start.

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.
