1.  How to fix SQ 30LB washer would not stop after final extract (Spin)?

  |   view attached

I have a 15-year SQ Washer that would not stop after the final extract Spin. (Model SC27MD2YU40001). Attached is a video showing the machine.

 My service technician replaced the following parts but still didn't resolve the issue:

  1. Solenoid
  2. Capacitor
  3. Door Switch
  4. Door Lock Microswitch

Wonder if anyone has come across this issue and know a way to fix this.

Thank you and look forward to hear from you!

Burnt resistor on your door lock control board.  Its that board with the blue capacitor attached to it.

Hi Chris - thanks for your help. I look through the parts manual and didn't see the exact names.

Do you think "door lock control board" and "door lock relay CCA" mean the same thing?

Also, do you think "resistor" and "Fuse" mean the same thing in this case?

Thanks again!

It's Item #28.F370430-1P Door Lock CCA.  There is a resistor that is soldered to the board that fails and prevents the machine from stopping.  Undo the clamp and harnesses, swap it with another machine.  Inspect the back of the board and you should see a burnt resistor.  Send it to Mountain Electronics for repair.

Chris, thanks for the info. I swapped that board with a working machine (same model) that I have and that didn't resolve the issue. Any other thoughts?

I have the same model. I've had instances where the machine will get to the end of cycle after the final spin and then re-start on it's own. It's usually an intermittent problem when it's happened so it's difficult to diagnose but I've resolved it in the past by replacing the timer.

Hi Sam, thank you for the info. Do you happen to have the part number for that timer? I will try to swap it with my working machine and see what happens.

Check your door lock assembly carefully or swap it out.
Something might be burnt out or binding keeping the switch in the closed position which keeps the tub tumbling.
Sounds like the door lock itself is not unlocking and you already swapped the board on the capacitor.

Timer would be my last option as they are expensive and a pia the swap.

Hi KC, thank you for the info. Where can I find the "door lock assembly" that you indicated. So far I either replaced or swapped out the parts highlighted in red on the diagram below:

Wil, I don't have the part number off hand. I've never purchased one. I send the old one to Reeco Timer to be rebuilt. I keep one rebuilt timer as a spare. It's a hassle to swap a timer given all of the connections and it's easy to mix up the wiring so I'd try some of the other suggestions first.

Turn off the power,  disconnect the coin mech, turn power back on and rapid advance the machine right before it's supposed to stop.  I hate swapping timers.   ​​

Hi Chris, thanks for the info. I swapped out the coin counter itself (#12 on image below) and didn't resolve the problem. I will try to swap out Coin Counter CCA (#5) below and see what happens. Thank you so much for the assistance!

Does your washer have one or two solenoids in the door lock mech?  If it has 2, failure of the door release solenoid will keep the machine running.  Binding at the time of door release could cause the same problem.  Sometimes door release solenoids can  partially short due to moisture from soap box overflow, causing the solenoid not to work.

The most likely problem areas are the door lock control board and the door release solenoid.

​John, your machine that will fast advance only is a door lock issue, wiring or bad connection. A lot of the times it is a connection issue after you have changed all that you did, most not having anything to do with the issue. I have seen the spade connector the wires are either broken, frayed or connector is coated with soap residue making a bad connection.

UPDATE  decided to start all over again    started  with the board  that  is attached to the capacitor     when I was discharging capacitor on working machine I got spark   when discharging cap on rapid advance machine  no spark    I decided to swap the capacitor and board not just the board     it worked  the rapid advance stopped and so did at the end where it would just continue to another wash  not sure if it is board or capacitor or both   its working so I didn't want to mess with it   worked fine all day      I didn think to put board and cap into other machine to see what happens  I will do that tomorrow and let you know     thanks again for all the input

Hi Winston,

I think it has one but not sure because I am new to this. The picture below shows the parts for the door switch assembly. Do you see more than one?

Chris - Thanks for the advise. I swapped out the coin mech and still didn't work. Another tech came by yesterday and he swapped out few other parts and didn't still work. This is a strange problem and a mystery. Any other thoughts?

Since you swapped the most likely cause, the door lock relay (#28), like Chris said, and you still haven't fixed it, the next most likely cause imo is the vertical door lock solenoid #11 ​, as Winston mentioned. They will eventually get gummed up and then cannot effectively pull the plunger up.

I used to replace them which is a little bit of a pain, but now I simply spray BOTH solenoids and the entire locking assembly with this:

https://www.amazon.com/Tri-Flow-Superior-Lubricant-4oz-Aerosol/dp/B002EX5B6O/ref=sr_1_3?ie=UTF8&qid=1515945230&sr=8-3&keywords=triflow+lubricant

This is an AMAZING lubricant that was designed originally for racing bicycle chains to lube without attracting dirt or dust.

It sprays on, but unlike oil based products such as WD-40 which will gum up after a while, THIS stuff, when it dries, leaves a dry Teflon coating which lasts a long time, and does not attract lint.

I have not had to change ANY solenoids for years because of this, and it has dramatically cut down on door lock issues, not to mention effectively lubricating any kind of lock such as padlocks, changer locks, or coin box locks.

No laundromat should be without this stuff.
