Maytag info I FOUND IT!.......YAY!

[phillymatt53]

Jeez, I MUST be bored today!
I took the control panel off of my Maytag A482 and guess what????
I found the schematic taped inside, and in great condition!
I only wanted to clean and re-lube the water level buttons shifter assembly, because the Small Load was sticking, and hard to deal with. - dried up grease was the culprit.
That's done now, easy fix, all 4 buttons operate smoothly again.

The next thing is to study that schematic, and figure out a way to make the machine so it gives a Warm Rinse on the Normal Wash cycle setting, which I use 99% of the time.
So If I can get Hot-Warm, and Warm-Warm, I'd be a happy camper.
I really don't want to put a manual "Warm-Rinse switch on the panel, I'd prefer it be automatic if possible, but that's an option I suppose.
Cold-Cold setting is fine, so it doesn't matter, so...

Being experienced in Home Stereo, TV, etc., I'm used to THOSE schematics, however a Washer system schematic confuses me some.
Maybe someone who really knows these machines can help me out here to lighten my brain-load.

OK.... so is it OK for me to add the 2-sided schematic on here?
I've scanned it in .PNG format, each page is about 3MB, size to fit 8x11 letter paper.
Perhaps it could help someone else with the same machine.

This is an easy modification to make, and there shouldn’t be any problem posting a picture of the diagram, Maytag always had kind of weird ways of drawing wiring diagrams, but if you study it, you’ll figure it out.

Bear in mind if you rinse clothes and warm water, they sour a lot faster because the bacteria left behind starts to flourish real fast. If you don’t get them in the dryer fast, unless of course that load had bleach in it then you don’t have much of a problem.

Cold rinsing not only works better, but it keeps the clothing or bacteria free until they get dried.

Cold rinsing not only works better, but it keeps the clothing more bacteria free until they get dried.

Ok, I'll download the service (schematics) here then.
I studied the diagram, and came up with a relatively simple modification.
It will be a relay, controlled by the timer mech SPDT switch, which controls the water solenoids. (contacts 3 & 15 = cold rinse power)
Basically, it will kick in during spray-spin, and rinse, and parallel the cold and hot water valves, thus a warm spray, and a warm final rinse-fill.
Cold wash/rinse selection is not affected.
I'm also thinking of putting a defeat switch on the panel, to allow it to still have a choice of cold rinse again.

Here's the files.... I had to convert them to .JPG to upload them.

How the hell does that timer knob come off?
It's the black knob with the brushed aluminum trim disk in the center.
Do I have to pry that disk out?
It seems like it's glued in place flush with the center hub of the knob.

I want to remove all the controls so I can take the whole panel to my workbench.

 

[qsd-dan]

Yes, gently pry the center disk out.

 

[phillymatt53]

Yes, gently pry the center disk out.

Thanks again!
However I did manage to get the disk out and was able to remove the timer, water level, and temp switch and move them, still connected, aside, so I could put it on the workbench.

I'm now designing the power supply/relay board.
I'm going to drill a 3/4 inch hole between the timer and temp controls, in order to mount a round "push on-push off" switch, labeled "Warm Rinse".
Turned ON, the relay will kick in on both spray rinse and fill rinse, by paralleling the hot & cold water valves, with a small neon light above the switch to show if it's on.

 

[phillymatt53]

Just finishing up the 12 volt power supply/relay board.
Got the front panel push button switch in too, and a "warm rinse" indicator light.
So far, so good, Looks great.
I'll post some pics later on.

That "Ladder Diagram" is great; easiest schematic to read and make sense of if one isn't a trained Electrician.

Yes, it is handy.
However, I'm more prone to the actual schematic since my decades of servicing has burned schematics into my brain.

 

[phillymatt53]

Well!
It's Finally Done!
Had I known the schematic was tucked into the control panel, I'd have done this modification 20 years ago when I moved here!
Pictures below, I think I did a neat professional job on it.
I gave the machine a "test fill" on the Rinse Cycle with the button pushed in. and voila!..... Warm Rinse!.... neon bulb glows!
Button out, cold water rinse back.

I want to thank you guys for helping me with this project.
By the way, does anybody have those brown square pushbutton caps?
The small and medium pushbuttons have wrong caps on them.

Wow, that looks amazing! If I didn’t know what an A482 control panel originally looked like, I would believe that the warm rinse button was factory.

Thanks mister washerguy!

I'm a fanatical nerd when it comes to me doing my restorations and modifications.
It "HAS" to look nice, and it HAS to perform perfectly, (for a long long time).
The simple part was custom building the power supply-relay board.
And I'm as careful as a surgeon when drilling, cutting, and fitting things.
I measure everything to within a Fraction of a Millimeter, I don't like surprizes when fitting things together.

Tonight, if I have any energy left after this, I'm gonna do a load of wash.
If not, I'll wait till tommorow, my old bones are tired.

I waited till this afternoon to do a load of T shirts in the Maytag.
I kept and eye on the machine while doing some nearby stuff in the basement.
My relatively simple modification works perfectly!
