F11 is a serial communications error. This is a symptom of an electronic control board starting to go bad. As defined by the technical information provided by Whirlpool, the error could also be caused by a loose or broken wire connector and/or the central control unit (CCU) (front panel). I would double check all your wire connections leading to the control board and CCU, first. Don't be surprised, however, if the problem persists and you eventually have to replace the electronic control board. To check, follow these steps: 1. Unplug washer. 2. Remove the three screws along the top of the washer in the rear that holds the top panel on. 3. Once the screws are removed the top should slide back then lift up. 4. The electronic control board is gray (or white) in color and located in the rear of the washer. It's impossible to miss. Double check all the connections ONE AT A TIME. 5. Double check the wire harness connections leading to the front panel as well. I hope this resolves your problem, but experience has proven that this is usually an Electronic Control Board failure. It could actually be a combination of the CCU as well. The part numbers are as follows: Electronic Control Board: 959503 Central Control Unit: 1025824 Both boards cost about $150 each. Let me know if this helps you.

An easy Fix. Take off the kick panel, 3 screws 1/4 inch. Make sure you have a shop vac ready or a lot of towels as there will be some water. Always disconnect power to washer and dryer, and turn off water to washer. Your filter most likely is clogged with change, screws, lint, and other household stuff that we leave in our pockets! Unscrew the cap on the filter, easy to find, since you have the kick panel off! Take everything out of the filter. Take your shop vac and **** out remaining stuff in hose. Also, **** up any water that has leaked in and around the washer. Screw the cap back on hand tight, put the kick panel back on, turn your water back on, plug it in and there you go! Maybe takes an hour and saves you a repair bill. If you are not comfortable with this procedure then call a maintenance person that is qualified.

Hi!

“F20” on display
(Water Inlet Problem—no water or insufficient
water supply) Select PAUSE/CANCEL twice to cancel the cycle
Unplug washer or disconnect power. Check the following: Are water faucets completely turned on?
Are screens at inlet hose connection to washer
clogged? Are water inlet hoses kinked? Are water inlet hoses frozen?
Do rate the solution.

Thanks

Sud= The unit has sensed there is too many suds in the unit it will flush and pump out for 5 min and restart on its own..This is caused by too much soap use..
From the book :
SUD Code=
If too much detergent was used:
—Run the unit through a Rinse/Spin cycle.
—Run a Normal cycle without adding any detergent.
This should clear the unit of the excess detergent.
1. Check the drain hose and make sure it is not plugged
or kinked.
2. Unplug washer or disconnect power.
3. Check wire harness connections to the drain pump,
pressure switch, and Central Control Unit (CCU).

6. Check drain pump.
