F code appears, can't reset any functions

This is a pure guess but where I would start looking; f20 code has to do with water level since water should not fill enough to pour out door.
whatever sensor determines water level is not functioning.

F26 code may appear the first time you try to use the washer. Open and close the door to clear the display.
The F26 code may also appear if the washer has run three cycles without the door being opened. Open and close the door to clear the display.
If opening and closing the door does not remove the error display, press Pause/Off or Pause/Cancel twice.
If Pause/Off or Pause/Cancel does not work:

1. Unplug the washer or disconnect the power for one minute.
2. Plug in the washer or reconnect the power.
3. Re-select the cycle and press Start. unsure of f27

the two possibles are faulty door lock or water still in the machine. the error code should tell you which. go to AEG and their troubleshooting page will give you the codes.
