How to Troubleshoot & Replace Whirlpool AP6016428 / WPW10181028 Washer Press Switch Retainer Clip

After watching a number of videos and reading a lot of trouble-shooting discussions online I had ideas of what to look for as possible causes of the overfilling of the drum. I found the water level pressure hose had worn through after contacting the rotor. After temporarily taping the hose, I found the service manual inside the machine so I ran it through it test sequences without any error codes. Suggesting the hose and not the sensor or inlet valves were the problem. I ordered parts last Sunday and installed them today (Saturday). I got a new hose and also replace a broken hose clip though I'm not sure it did any good at holding things in place, it is friction-fit into the back of the plastic drum assembly which moves a lot during the machine's operation. It even popped out while I was putting the hose back in place. So upon reassembly I added two loose zip ties to retain the hose away from the rotor in case the clip fails again. I hope our machine was a fluke otherwise I hope the routing of the hose has been changed for the better. While the unit was apart ( the dryer is stacked on the washer), I decided to clean the pre-pump clean-out which was much more of a challenge because the entire front of the machine needed to be removed along with the door seal. It would sure be nice if it had its own door or there was at the very least a lower access panel. I noticed other models have a door or access panel so that is something I'll look for new time we purchase a front loading washer. This part of the process was much harder than fixing the hose which only required the top and back of the machine to be removed.
