Whirlpool Washer - WFW6620HC0 - LOC Error - Motherboard (ACU) Replacement

Whirlpool washer not responding in LOC or out of LOC mode - not responsive but turning on.

[@andyhernandez5500]

Thanks! A rat shewed up my harness wiring, ordered the part 14$ and installation was not going well till saw your video!

[@lauraharte8196]

THANK YOU!! I have the exact same issue and also went through replacing the control panel and all before realizing it was the ACU and there are zero videos for this model. All videos show an ACU in the front corner that is just easily removed after taking off the top. What a pain! And my machine is only 1.5 years old. I thought Whirlpool was a good brand... lesson learned there. Now to roll up my sleeves and get this taken care of tonight.

[@devaunramsey923]

Glad it helped! Whirlpool is a good brand comparatively. I’ve been repairing appliances of all ages for about 14 years and sometime around 2012, all brands (I mean all) took a steady nosedive in quality. Avoid LG and Samsung as they still break like any other brand BUT their major repairs usually cost about the same as a new appliance, and there really isn’t any help on line to DIY. I completed this ACU repair a little over two years ago and it’s still running strong.

[@RLM1120]

Same thing within 18 months. Total junk. Parts and repair so expensive that just buying a new washer. Go to a Speed Queen

[@Abba850]

Your video is a life saver. I suspect the fuse on my motherboard is broken so I'm in the midst of removing the board.

[@dolfan1967atyahoo]

THANKS!!! I had the same symptoms you described and also my washer WFW5620HW0 and ACU # W11322903 would softly chime (thank goodness) every 10-15min. Watched tones of tubes on the control panel and door interlock, but I knew that was not my issue. Nine days downtime for back-order/delivery and only one 2-load trip to a laundromat.

[@TamekaIS]

Thank you so much for posting this. I tried to look all over the internet for a solution. So much appreciated.

[@devaunramsey923]

Glad you found it! Gotta help each other out.

[@tjscott395]

Nothing in my owners manual about this “Loc” error code. I HATE that I have to hold any buttons! I don’t have kids, so why is this something I’m stuck with? Thanks for showing me that all I had to do was hold the “Extra Rinse” button to clear it! THANKS!!!

[@CharlieManoogian-or8ex]

Great video helped a lot exact same model my symptoms were after countdown would not start .in diagnostic mode. Screen went blank no codes then powered off. like you, I started with replacing the door lock switch when removing and putting on my ohmmeter and simulating door closed three prongs all red open. This is normal.($70 later)😢 I tried to get appliance repair to come with the part explaining all the troubleshooting I have done,no luck with that. I’m in southwest Virginia. Everything is 2 to 3 weeks .now waiting for part to show up. lowest price I could fine with shipping was just under $300. I decided to roll the dice purchased on eBay allegedly new in box with three-year warranty total $165, to be continued

[@joemaryland]

TY for this video, my board just fried, no codes or power. I needed to know which panels I needed to remove. TY again.

Thank you! I’ve been scouring the internet to find a solution! Thank you thank you!

Thanks for posting this. I had a F6E2 error code which left the display panel blank and unresponsive except for some beeping occasionally and the F6E2 at times. I was told that Whirlpool put out a service bulletin that said the front panels that have been return came back almost 100% ok but the ACU's had a consistent problem. My Model# is WFW5620HW0 and ACU # W11322903. I plan to replace it in a couple of days. I was happy to find your video as I was prepping for the repair. Thanks.

[@devaunramsey923]

You’re welcome. Hope the repair went well for you

[@goldmu08]

@@devaunramsey923 Repair went perfect. No issues since.

[@yehmustafa2959]

I'm getting the same F6E2 error code, I tested the motor with multimeter and it's good. I'm hesitant to spend the money on replacement ACU on washer that's barely 2yrs old. Do we know what's really wrong?

[@williammaes5655]

Getting error code F6 E3, generic error that indicates the board is not communicating with something, so helpful. I went into the Diagnostic Submenu, cleared the error code, ran a few diagnostic tests, determined everything worked except the unit would not spin. There is individual Test #7 that is suppose to drain (if needed) and then spin for 5 minutes. Mine drained, but no spin and then threw the F6 E3 code. Also ran the Quick Test with 12 mini steps, again everything worked...door locked, cold valve fill, hot valve fill, drain, recirc pump, drain again, but no spin...and threw the F6 E3. I called a local repair shop to see what they thought, either the control board or the rotor/stator/motor (seemed more logical to me since the Spin is what generated the error code). But they said most likely the control board. So that is what I'm trying first. Mine is a little different model, wfw8620hc3, but looks identical. I watched your video to see if there was a trick to getting the control board off...Thanks, I knew after taking the screw off it had to be something simple, but I couldn't get it to slide off...now I see it's a zig zag slot, going up then straight.

[@davidgreen65]

Hi, I'm having the exact same issue. Did you manage to fix it from changing the ACU?

[@williammaes5655]

@@davidgreen65 It was the control board, no problems since I replaced it.

[@davidgreen65]

@@williammaes5655 Thanks so much! Where did you end up ordering it from?

[@williammaes5655]

@@davidgreen65 Ordered from a local furniture/appliance store, it was about $30 more (than the cheapest on-line site), but they said they'd exchange it/give me credit (if it didn't fix my problem) for the stator/motor (which I was betting was the problem, but wasn't...it was the board).

[@nicholasolstad3355]

Thanks for the video, I might have missed it but what were your symptoms? My washer is beeping erratically and stopping during cycle

[@devaunramsey923]

Unresponsive control board was the symptom. Only loc was responding

[@nicolasgalileo7209]

Awesome price at the end of video 😊

[@devaunramsey923]

Let me know if you have any questions - happy to help!

[@shellw3288]

Thanks for the video! I was able to install the new one before I found your video, but I need help with where the wires go. Ugh I didn’t take the right photos. Anyway you can show your pictures of the wiring set up. Please!!

[@devaunramsey923]

I won’t be able to help you with a photo. However the wires should have a color band that matches the color band on the new ACU

[@shellw3288]

@@devaunramsey923 I was able to figure it out and it’s working great! 👍🏼

[@kjalicea8048]

How???

[@musicroxz1]

Long shot, but do you still have those pictures? I assumed the terminals would only go in specific spots but as I took it apart I realized my mistake

[@devaunramsey923]

I don’t have the pictures still. The colored terminals on the board do correspond with the colored terminal connectors. Most are size specific as well

[@briantimms375]

Do you have photos of where the wires were plugged in? I pulled mine out and 3 wires were no longer connected.

[@simpsonpropertiesltd]

Excellent video! Thanks for sharing. Did you purchase the part directly from Whirlpool?

[@devaunramsey923]

Thank you. No from Marcone

[@sunday9373]

Hello DeVaun, Happy New Year!! Would it be okay if I inquire where you found your ACU for that price? Thanks so much!! Appreciate the time you took to video this!!!

[@devaunramsey923]

Happy new year! I have a local appliance parts supplier I ordered this from. Pricing may vary by location. Im sure price has increased since the recording based on the merit of inflation and the international microchip shortages

[@andrewrowzee5411]

Can you show your new terminals went I can't tell if I am colorblind if red or brown on the harness??

[@andrewrowzee5411]

[@Mr_Corn]

Thank you so much for your posting, I think I had the exact problem as yours. No response from the main display at all. Also I opened up the top cover of the washer and saw the ACU is blinking exactly like yours. Would like to confirm if the ACU blinks like that, does it mean the ACU is bad and should be replaced? thanks a lot!

[@devaunramsey923]

During the video I mentioned that the blinking was present before and after the replacement of the ACU, so I’m not sure if that is indicative of a system failure or maybe just a power status light

[@Mr_Corn]

@@devaunramsey923 I called the whirlpool service, said will charge $100 for just diagnosis. And replacement plus labor will be additional. Do u think it is worthwhile for them to take a look?

[@devaunramsey923]

@@Mr_Corn perhaps. That’s up to you to weigh the cost and your abilities

[@FertileMyrtleTurtle]

Guys there is a diagnostic mode and you can make it do test 12, my machine would lock actually lock the door then, but still no spin

[@donb1965]

The front panel on this washer isn't the most obvious on how to do things. After I got the LOC error on mine i was able somehow to do a sequence to get it unlocked. I think i hit the power and then immediately hit and held down that extra rinse button while the LOC was still lit up, think i saw a 3, 2, 1 countdown on the right...although i won't swear to that, not sure if i continued to press Start or not..but yeah, hopefully don't have to do that again. whew.

[@sprng319]

It worked! Thank you so much😊

[@backinactionllc]

It's so unacceptable for these Whirlpool models this new to burn through boards. Same issue times 2. New board lasted 8 months then went. Junk...

[@devaunramsey923]

I hear ya. It’s very frustrating. I think manufacturers should start to warranty beyond 1 year maybe 3 even. That would instill a bit more integrity behind their brand and eventually cause a better product

[@nicolasgalileo7209]

Hi there, how much did you pay for the board? Pls n thx

[@classikz]

$541.... whirlpoolparts.com

[@johnpatrick1588]

These electronic front-load washers and the higher cost are not worth it. Some settings can take an hour or two to do a load. I rather use more water and still be young when the clothes are finished. I had coin laundries and these machines between cost and time to finish a load would bankrupt me.

Whirlpool is now junk
