Maytag Bravos MCT Washer Service manual wanted

[remotelarry]

Need manual the covers the MVWB850WQ washer. 

Especially interested in the schematic of the control board, tough I doubt that is published since it is not likely considered a serviceable item.  Rest of manual or tech sheet on this model type would be appreciated since the diagnostics are a little different than shown in other Bravos manuals

Thx
Larry

Tech sheet should be located in plastic bag on inside of cabinet front. Unless some Bozo didn't put it back after looking at it. (One of my pet peeves  )
Use a putty knife to release top hold-down clips.

There are two different tech sheets depending on if it's a Q0 or Q1 at the end of the model number.
I have attached both of them for you. Have not looked to see what the difference is.


What is wrong with the washer?

AJ and Scrapiron,  thanks both of you for the information.  The difference between the 0 and 1 at the end of the model number should only be color.  Not sure that impacts the tech sheets unless they mention.  I do see some differences in the wiring diagram and in the pictorial of the control board, so maybe there is more to it than I thought.

Thanks again
Larry

AJ, a couple of days ago the washer was throwing dL code and diagnostic modes show F82 and F83.  The washer had been repaired once before for a broken lid lock latch by a Sears tech and I was attentive enough to see that removing the top, etc, was not a big deal so I took out the lid lock assembly this time and checked the resistances per information on the web.  Indicated a broken lid lock assy.  I took the assy apart to check inside and there was a burn mark around what looks to be a thermistor or current limiting resiston in series with the little electric motor.  The device in series was burned up completely so I bought a new one assy, plugged it in and still showing dL code.  Last night I removed the control module and the lid lock motor driver chip had its top of the package blown off and pin number 2 had completely fused off.  I am an electrical engineer and to see this kind of damage on the chip was surprising to me.  It would take a lot of current to fuse one of these pins and blow up a chip like this so something happened somewhere to cause this kind of damage.  So it's off to get a new control board.

Cheers

NO, that's a manufacturing change ...
Q is color = white
B  = black
L = silver
R = red

Got it.  Mine is MVWB850MQ0 so it's white, rev 0

Thanks.  And the spec sheet for the "0" unit matches my washer.
