Professional Appliance Service – Checking the Washer Pressure Switch


I recently had to call in for some help with our family washing machine that wasn’t working right. I didn’t have time or want to risk messing things up, so I opted to simply call in the professionals at Austin Appliance Repair Masters (http://austinappliancemasters.com) to fix this one for us.  They were great – they showed up on time, took care of things quickly and efficiently, and even let me record what he was doing so I could make notes and share the whole process with you here.  So without further ado, here’s my most recent visit with the Appliance Masters.

Okay, what we’re going to be doing here today is checking the pressure switch on this washer that needs a repair.  What the pressure switch does is control the water level in the washer.  And this one’s not quite filling up as far as it should, so we’re going to check that out. This is a Kenmore Model here. We need to pull this apart…if you’re not familiar with how these come apart; we have another video that will show you how to disassemble this. And, it would under a Whirlpool style. So, come on it let’s take a closer look and see what we’ve got here.

Okay, now that we have the cover apart. We’ll put this over here. And this is our pressure switch located up here. It’s right behind the knob that controls your load level. And you’ll see this rubber hose coming down; it comes down to this chamber down here. The way this works, is as your water level fills up, it creates pressure in this chamber, which trips this switch. The pressure will trip this switch here.

Okay, here, so what we’re doing, is I’m going to disconnect this hose…I’m going to disconnect it here…and, actually, I can see right in here…I don’t know if you can see that in the video, it’s got some gunk built up in there, so we’re going to clean that out, and actually, and I think that’s what was preventing the pressure switch from tripping…so, it didn’t know how much water was in here…

So, what I am going to do is grab my multi-meter…it’s the here, and I’m going to set this one, on the ohm setting and what we’re going to do, is we’re going to make sure this is working properly…we’re going to check it for continuity…and all that is saying that there’s making contact across the switch, and my end…got this set for continuity…mine makes a little beep when…makes continuity…

So the easy way to check this is here…we’ll just come over to these wires here, and now you can see what we want to do is, we want to get on this brown wire here, and this purple wire there…and I want to take this hose…and, I’ve cleaned off the end here…there’s probably a lot of bacteria and stuff, and what I want to do is blow into this to create the illusion of pressure, and it should trip this switch…and, we should here my multi-meter beep.

Okay, make sure you get a good contact here, so this switch is working properly, it was just a matter of cleaning out the hose, and if there’s any, any holes in this tube also…you need to replace that tube there.

Okay, this here is a close-up view of the pressure switch, and the hose…routing down…to the chamber…on the side here…you can see that. I hope this information helped you out.
