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.



The "SUDS" error can be caused by too much detergent, improper detergent, drain pump/drain line problem, or pressure switch malfunction.

1. If you are not using HE detergent, you need to be. These washers are designed to use HE detergent which is formulated for wash tubs that use 5 to 7 gallons of water. If you use regular detergent, you are, in affect, placing a higher concentration of detergent in the washer that is normally formulated for wash tubs that have a 35 gallon capacity. The manufacturer should have a disclaimer in the owner's manual explaining this. In most cases this will also void your warranty. NOTE: Prolonged use of the wrong detergent can damage the drain pump components and or wash tub seals.

If you are using the correct detergent, double check the label to make sure it is not double (2X) or triple (3X) concentrated. You could still be placing too much soap in your wash.

To get rid of excessive detergent, place the washer on a RINSE & SPIN cycle, then run it through a normal wash cycle with NO detergent added. You may have to repeat these steps depending on the amount of detergent used.

2. If you do not have a detergent issue, double check the drain pump and drain lines to ensure they are not obstructed in any way. Click on the following link for step-by-step instructions:

Obstructions in the drain pump and/or drain lines can attribute to air getting trapped in the drain pump and cause the error code. Double check all electrical connections to the drain pump and Central Control Unit (CCU). You will need to remove the top panel of the washer to access the CCU. This is accomplished by removing the three screws in the back of the washer that hold the top panel in place. With the screws removed, slide the panel back, then off. The CCU is located directly behind the wash tub in the center of the washer. The Drain Pump connector will be the 6th connector (facing from the front L to R) in the center of the CCU.

3. Check the Pressure Switch to ensure it is good. The Pressure Switch is located to the right of the CCU as you are looking from the front. It is a small cylindrical shaped device with a connector plug and an air hose attached. The switch can be checked at several water levels by removing the plug and taking resistance readings at the connector pins. Readings are as follows:

(Pins are numbered R to L facing the from the REAR)

Pins 1 to 2 (SUDS Detect) – 0 ohms
Pins 3 to 4 (Overflow) – 0 ohms
Pins 4 to 5 (L1) – 0 ohms
Pins 4 to 6 (Empty) – 0 ohms

What does 5ud mean 10 minutes from finishing 5 Ud displayed can't open door?


The SUD (not 5UD) code is displayed when excess foam is detected (possibly because excessive detergent is being used). If your machine does not cure itself, you may have to run an "Eco drum clean" cycle (if your machine has it) or a 90 degree cotton cycle with no detergent and no load.

Whirlpool duet f35 error-suds error


Maybe this will help, but I'm not sure

Condition:
SUDS LOCK (Overdose of Detergent detected during the Wash Cycle)
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.

Check:
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 connectors to the Drain Pump, Pressure Switch, and Central Control Unit (CCU)
Check/Clean Drain Pump Filter of foreign objects
Check Drain Pump
Check Pressure Switch
Check CCU

I START TO WASH AND A SUD APEARS AFTER 4 TO 6 MINUTES IT STARTS TO WASH THE WATER POURS INTO THE MACHINE AND IN A MINUTE AFTER IT STARTST IT STOPS ALL THE LIGHTS GO OUT AND A CODE F35 FLASHES CONSTANTLY...


The SUD display could mean several things. A faulty drain pump, excessive detergent, excessive suds, or an extra heavy load.
Open the front bottom panel and clean the drain pump filter of foreign objects. Also check the drain hose and make sure it is not clogged or kinked.
If too much detergent was used, run the unit thru a rinse/spin cycle then a normal cycle without adding any detergent.
Check the wire harness connections to the drain pump, pressure switch, and control board

Suds, and F35 keeps coming up when trying to wash!


I would put bleach in the detergent slot, run through each cycle. Then run the cycle again with just water. These are really touch when using detergent. Just a little bid of suds sets these things off.

My Kenmore Elite HE5t washer flashes SUD continually, then goes to F35 mode and shuts off. Help!


Sometimes the SUDS/F35 is because of TOO MUCH detergent. To clear you have to set the cycle on rinse and then keep pouring cups of water into the detergent container as the cycle is going. You might have to do this a few times because if the SUDS message comes up the water flow will stop. Just unplug and try again. Also when the detergent container is finally clear you will see the little rotators gears move around when the cycle starts.

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.

New Kenmore Elite Front Loader will not get past 'Sud' cycle,


Hello wheeljc; I had the same problem when I purchased my Kenmore Elite in 2006. I have a HE4t front load. It's possible that you're using to much detergent, if you're using HE liquid it only requires a small amount and does a very good job.
