Question about Whirlpool Duet GHW9150P Front Load Washer
The fault code F 20 is for "No water or Insufficient water supply". There are a few possible causes.Even brand new machines can give this code if one of the internal hoses gets kinked.
There are some things you can check before resorting to a service call. First check all your supply lines. Make sure the valves are fully open and that the lines are not kinked or pinched off in anyway.
The next step would be to remove the supply lines and using a bucket, check the water supply. Make sure the pressure is adequate.
After you have checked theses items clear the code by pressing Pause/Cancel twice. If there is any water in the washer it should drain and unlock the door after 3 minutes.
Unplug the washer and then plug back in. Run a wash cycle and see if the code returns.
If it does the next place to check will be internal.
The first item is the small supply hose that runs between the pump and pressure switch. Over time it can become plugged up. If you are comfortable with working on this simply remove the top or back section. The pressure switch is located near the top of the washer. It is about 4 in. round and has wires and a 1/4 inch black tube attached to it.
Remove the tube and clear any obstructions. Then reassemble and test again.
If the code returns it may be a bad switch or a clog in one of the main internal supply lines. From there if you would like to continue repairing it yourself please let me know and I'll try and talk you trough it step by step.
Hope this helps. Good luck.
