How to Troubleshoot & Replace Ge AP4358796 / WH12X10378 Switch, Pressure

The washer worked fine on the small or large load but when placed on super load it would overfill. Replaced the pressure switch based on this sites recommendation and it worked like a charm. Took about 10 minutes for the whole job. 

Trouble shot it as the prssure switch! and pruchased from Applianceparts.com. 

Had an appliance company come in and tell me it was going to cost $259 to fix. They claimed the part had to "be ordered". Waited four days and called them to find out why they hadn't come back or called me, only to find out that they never ordered the part and was told that "it will be here tomorrow". Got mad. Went online and found the part, then went on You Tube to see how to do it. Ordered the part and it came the next day. Hubby fixed it after work, in 10 minutes. Part cost: $29 + shipping. 

Took front of washer off, noticed tube from tub to level switch was dirty. Cleaned tubing with bleach and pipe cleaners. Tried washer, still overfilled. Replaced level switch, now woks properly. You should be careful removing the switch so as not to break off th plastic tabs that hold the switch in place. 

Change the pressure switch, clean the hose also change water inlet switch, it is working now. 

Ordered the part online, suprisingly I got it the next day and in about 1/2 hour, done works great,! 

Son did the repairs 

Install new pressure switch 

Replaced pressure switch. However the plastic that houses this in place was cracked. Was able to drill and tap two 6-32 screws into switch mount (metal plate) through panel and securely mounted level switch. Screws placed under control knob. Also used oval head type screws to reduce knob clearance. Working great with no over fills on highest setting. Old machine is working up a storm. Family just came back from Walt Disney World with lots of dirty laundry. 

First checked to be sure the pressure tube was clear by disconnecting from pressure switch and blowing in it , it was not clogged so it had to be the switch ordered the switch and changed out , took about two minutes .I next set to run water in the tub ,it stopped at the right level , mission accomplished .
