Washer door lock solenoid is not working

I have a Whirlpool Duet WFW70HEBW0. When we close the door and select our cycle we don't hear the loud bang of the locking solenoid any more, just a couple tiny clicks. I got into the CCU and pulled out all the connectors and put them back in, but the problem is still there. I tried to run the diagnostic test, but I don't understand how to do it. If the power isn't turned on, and I press "Spin" "Soil" and "Extra rinse" three times in a row, nothing happens. If the power IS on, and I press these three buttons three times in a row, I hear all the sounds, but I still don't get any error codes, just minute timings. Should I just replace the door switch??

 

Welcome to the forums.

Make sure you have the right tech sheet.
The first step should activate the door lock.

Please let me know when you have it as I don't leave tech sheets posted.

Had similar issue recently, the lid lock solenoid is bad, it's a very simple part to replace, just have to get the lid up and swap parts, if I recall it was a $50 fix.

Lots of videos for the repair!

 

Dear PJMax and Marq1,

Thank you for your help! I found a service manual inside the top panel. It told me to check three of the connectors on the central control unit, so I unhooked them and plugged them back in. Same non-working solenoid. So I just ordere
d the part ($70 plus tax) and put it in. Took about 5 minutes. Works like a charm. However, for some reason, the time gap is longer for when the solenoid clicks in with its loud bang. But if it ain't broke, don't fix it. We are happy it's working again. How much did I save over having a service tech come to the house? $300...$400? So nice to have websites like this one and numerous Youtube videos. Imagine what it was like 10 years ago. Now almost anyone can repair almost anything just by searching the internet. Yay!
