Question about Kenmore Washing Machines
“F21” (AKA SD) is a Long (SLOW) Drain error (LD). If the drain time exceeds 8 minutes this error code will be displayed. In addition, a “SUDS” error may also be displayed. This may be an indication of a drain pump problem and/or clog in the drain line. You will need to check the following:
1.First, attempt to unplug the washer for at LEAST 30 minutes to reset the Central Control Unit (CCU). Sometimes this is all that is required to correct momentary glitches with the unit. If the error code returns, proceed to step 2.
2.Check the drain hose to make sure it is not kinked or clogged.
3.Check the electrical connections to the pump and ensure the pump is running.
4.Remove the drain pump filter and check for foreign objects and/or debris.

If the above procedures do not correct the problem, it is recommended by the manufacturer to replace the drain pump.

The F21 error code is an indication that the unit has too long of a drain out condition. If the control calls for the unit to drain & the water does not drain out in 8 minutes or less the unit will stop & flash the F21 error code. I would recommend checking the drain pump & pressure switch circuit.
Clear pump of debris. Tilt machine. Take off front panel. Unscrew large white drain plug. Remove debris.
Unplug from power source...remove front lower panel (3 sheet metal screw wirh 1/4" drive head located on the lower lop of the panel)...open pump strainer (looks like a large stove knob, Turn it counter clokwise, lookout! lots of water will gush out... back flush the pump by filling the outet of the drain hose ( this may dislodge debris that may jam your pump)...re-assemble, plug to power, and turn-on. That will help get rid off the debris.
It can be done if you are patient and able to figure out how the plastic thing comes apart. Good luck!

SOURCE: HE5t washing machine flashes F35
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.

F21 error means that the drain time has exceeded 8 minutes; this will turn off the water valves. Press PAUSE/CANCEL two times to clear the display. If errors still remains then please check the drain hose and make sure it is not plugged or kinked. Disassemble the washer by removing the back from the washer and check the electrical connections at the pump and make sure the pump is draining. Also inspect the pump filter for foreign objects. Before disassembling remember to turn off the power and disconnect the washer. If it still doesn't help then there is an issue with the pump and you'll need to replace it. Hope this helps... Please post back if you need more information.
