WD30 stinks too much, use some 3-1 oil.

Hi, This F26 error means "door switch error" If the door has not been opened for three consecutive cycles or the door switch is open while the door is locked for more than 5 seconds
Do the following to fix the problem:
Open and close the door
Verify CCU operation by running a Diagnostic test or any cycle
Push the door and check if its completely closed

The first thing to try is to hold the cancel button for 15 seconds. The more labor intensive solution is this: Remove the panel beneath the door (2 or 3 screws). Reach up, there is a little "ring" beneath the door lock. Pull this down, it releases the mechanism.

I would bet the water inlet valve is weeping. It may not seal shut every time. It could have a piece of rest stuck in it also. It's cheap and easy to replace. The part # AP3128776.

It is saying there is a problem with your door Lock. when you close the door does it hold like it use too? try to open and close the door if it doesn't really close properly then you will just need a door latch. If the machine gives you an f11 code then its the main computer board that can also give your the door lock error. I would check the door first though.

its best if you call whirlpool to set up service call. tampering with your washer could void the warranty

yes, it may be as simple as a broken clip where the door opens & closes

can oyu oppen the door nad physically push in on the door switch( little grey switch atop the door opening). do you hear it clicking on/off??? if not you have a bad door switch.
