Whirlpool Duet washer F21 SUD Error

I haven't kept this blog updated because it seems like I just keep doing all the things I have already blogged about. Just as soon as I fix one thing, something else breaks. It is a continual maintenance headache.

For example, the Whirlpool Duet Washer's F21 SUD error. I get this message every year or two and I do the same thing. But I realized I have never blogged about it before.

The F35 error means the water isn't draining from the washer fast enough. The reason is that most likely the drain's catch is plugged. Sometimes (believe it or not) a sock gets in there. Or, if you use too much detergent, you'll get a gel-like build up. Or lint. Whatever is blocking the drain? You have to clean it out. And it ain't fun. It is smelly and disguising, but is absolutely a DIY activity.

First step? Unplug the washer. Then, take the front panel off the washer. There are three screws at the bottom of the case, and then the cover lifts off.

The drain catch can be accessed by removing a large round thumb screwed cover... but wait...

If you unscrew that, up to three gallons of fowl smelling water is going to pour out. They have improved newer models so the access extends outside of the washer's base. My model? It is inside - which means unscrewing the cap will dump that fowl smelling water inside the bottom of your washer - not good. 

The solution in my washer is to remove the red tab that holds the cover in place, pop off the feet that connect it to the bottom of the washer, and then pull it forward as much as possible.

It will not pull forward as much as needed, so, you'll have to create something that will divert the water into a bucket instead of into the bottom of the washer. Perhaps use a funnel, or, cut off the bottom of a milk jug or something.

Also, line the area with old towels because things are likely to get wet!

When you are ready? Screw off the cover.

It is going to look gross and stink really bad (especially if you don't do this yearly!). You have to completely clean it and get it down to the plastic.

Next, check the pipe for any debris. Shine a flashlight in the hole and remove any debris. 

The pipe assembly connects to a plump. The pump connects to the right by a small hole in the pipe.

Stick your finger in that hole and feel for a rubber gasket. The gasket shouldn't be loose (a little loose might be OK). If it is loose, you'll have to get a repairman to fix it because the pump isn't working properly at evacuating the water.

That's it! Reassemble everything and you are back in business!
