Whirlpool water softener service error 

This was helpful, as my softener was showing the same symptoms. So I ordered a new switch from Amazon, and the problem was still there. I was almost certain that I was going to have to replace the water softener, BUT THEN I took a closer look at the cam wheel that actuates the switch. It had a pretty good crust of salt and corrosion on it, especially in the recesses. So I scraped it all clean with a little screwdriver, and reset the machine again. It went into regen mode, so I will monitor and see if this truly solve the issue. So: make sure you look at the cam wheel and be sure it's clean enough for the switch to operate through its full stroke.

Thank God for youtube. I just install a brand new whirlpool softener and I got an Err1. When I took it out of the box the display was disconnected and the little switch didn't have the two wires hooked up to it. I hooked up those two wires that I thought were just free wires and resolved the issue. Thanks!

Thank you Dan. Mine was doing the exact same thing. It was nice to see the same problem with a pretty easy fix.

This is probably the only reason I should use RU-vid, thanks for the help!

This was helpful. I had the same problem, found salt crusted around the switch, and when I disconnected the wires the little metal tab on the switch where the green wire goes broke off.

Mine was the wiring to a plug I inadvertently forgot to plug in. Thank you.

Thanks. Very helpful.

Mine has a little bit of water inside those recessed spaces on the white housing. Is this ok, or does this mean I have to open that up and replace all the gaskets? It's not a lot of water, but I'd say about a tablespooon of water comes out each time it regenerates. I see there is water on the top of yours too. Is that a big deal or not really?

Did you get the switch on amazon, also can you give me the model number of the switch. Thanks again for all your help. I think this is what is causing mine to not soften the water.

Mine started to make that noise after we lost power for 4 hours during the bad storm were getting today. I had shut off the water at the main to help lrevent freezing pipes when power came back on it was doing this any suggestions

I had done w you mentioned, but the rotor isn’t turn although the motor it turning, the cam still shows closed not opened position

So if the black gear is not spinning I need a new switch?

Dan, I have the same Whirlpool Water Softener. My problem is that I have standing water in the salt tank. I would appreciate any help that you can give me. Gary Jochum

What would you do if you have an error code if 4 for the same softener

This is what’s wrong with mine but I couldn’t hear what you were saying on how to fix it.

Where do you find that part?

what does an error code 4 mean?
