How to replace Washer Water Level Pressure Switch. This error code indicated faulty water level and wash cycles were exhibiting either no water or too much water. Saw utube vid using this part for this type of problem and so far the repair is working well. Part arrived in 2 days, it was the right part and the machine is working the way its supposed to so I'm very happy. The worst scenario would have been to hire a repair guy to rip me off for a "Johnson Rod" I didn't need. 84 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
