How to Troubleshoot & Replace Whirlpool AP6022522 / WPW10514214 Pressure Switch

Replaced Water Inlet Flowmeter and Switch-WI. So far haven't received the error. Easy and quick to install both parts. 

Replacing the water inlet flow meter. 

Replaced the electronic control board that was mounted behind the water dispenser. 

I ordered the three parts most often found responsible for the FH error code. Then I watched the part installation videos to ensure that I knew the correct locations for the parts. Parts arrived 3 days after order was placed. Installed all three parts in less than 1 hour, and machine is up and running nicely. This was a huge success in terms of avoiding a costly service call, and having the washing machine back running in a timely manner. Thank you ! 

Changed the pressure switch and flow meter 

I ordered a pressure switch (#W10514214) and when I went to install it, I discovered that the connecting pressure hose had chaffed badly and had a pin hole leak in it. The chafed hose wasn't visible from the top and only discovered after I removed the back cover from the washer. I replaced the switch and hose and that fixed the problem. The real problem was ONLY the leaking pressure hose, but I decided to keep the pressure switch anyway.
