Incredible Job

What a great job, Jon. The machine looks wonderful, and I love all the intricacies of this type of appliance. Combo's were truly the engineering marvel of the laundry appliance world! Thanks for sharing all the photos and knowledge. Congrats on your success with it, and here's to many "broiled dry" loads! :)
 
I'm sure it'll be a success, Jon!!  Can't wait to see it in action again (possibly in person)

Okay update today

What I discovered yesterday really surprised me. The Combo would not engage the timer motor on a full water level switch. I took the machine apart and went through every circuit! I came up empty handed as to any circuit that would engage the timer motor on a full switch. And that is why when I first opened the machine up I found those two wires taped together that I called a bojack move by someone in the past ! See the reply #49 above where there is a picture of this. 

It turns out John remembered correctly , this was an after factory fix!

 

<span style="white-space: pre;"> </span>It means people!! - that GE built a machine - sent it down the assembly line and discovered AFTER the fact that they hadn't planned a circuit to engage the timer motor on a FILL !! A colossal booboo!

 

<span style="white-space: pre;"> </span>This will be one of the reasons Paul's '56  machine is SO different than my '55 is and why electrically the '55 is the unique oddball of GE machines!

<span style="white-space: pre;"> </span>So I got rid of the bojack fix as seen in reply #49  and installed a jumper on the timer block which is what should have been done 59 years ago! See the red jumper crossing the timer block with the yellow connector. This circuit carries the signal from the level switch to the timer motor to activate the timer at a full tub of water. Now after electrical testing yesterday it all works.

 

So hopefully today she will get her virgin load!

 

I have never seen such a booboo in all my 35 years of modern appliance living. This is a rare one.

That is odd Jon, good detective work in finding the issue. It's also odd seeing GE using a Mallory Timer, unless that was common in the combos, it's rare.
 
Robert, GE used the Mallory timers on their pre-1957 dishwashers as well.  That's one of the reasons why I was so ticked off that I had pull a working motor out of the 55 GE pull-out dishwasher to revive the 56 combo!

 

Jon - great detective work!  Can we send you back to 1955 to kick someone's behind in Louisville??  LOL  
 
1955 GE Combo

Jon, you should never mess with factory approved field wiring corrections, you could have saved 5 months of time on this project. LOL.

All GE combos used Mallory timers, my guess is that they never built enough Combos to warrant designing and building a timer for the combo themselves, See post #90 in this thread.
 
Paul

Yes send me back I have a few words to the wise for 1955!!

 

John- If I had only listened but you know me Mr Hands- On. Actually there were so many problems with this machine I really can't see any short cuts, the one I took kicked me in the butt today!

When I rebuilt the water valve I reused one gasket in the WHOLE machine because its a quirky gasket. Well the water valve typical for a Combo restore blew water all down the inside and got the insulation all wet today!

So take it apart again and run to the "Hadhware" store to find a new O-ring. Never never never reuse a water gasket!!

 

 

 
 
Okay Everybody here is the Virgin Wash

I taped the virgin wash yesterday. 

This whole restoration began on Nov 25, 2013 and it finally has come to full operation after 7 months. Combos are complex machines, and they take patience and persistence to get back on their feet. Especially after 59 years leaving the factory floor. 

It can be a frustrating experience but I wanted the club to see an complete restoration from start to finish and this machine gave a lot of kick back so that you got to see every system completely disassembled and rebuilt from the ground up.

 

Some interesting differences to this unique machine that set it apart from all later GE Combinations-

First it has a transmission not 3 belts, this makes for a quieter machine overall.

It has a separate pump motor engaged from the timer.

Like the 1956 it has a scissors balance mechanism.

Unlike all other Combinations, this machine has 3 baffles in its tub, not 4 not 6.

It tumbles & spins counterclockwise only - sorry Chuck!

It has 5 Rinses and I discovered yesterday that the first rinse is really a fill/drain. The machine fills and as soon as the water level switch is satisfied the drain motor comes right on. All the other 4 rinses actually tumble for a minute or two.

The 5th rinse is a hot water rinse, I'm guessing to reheat the clothes for the Broil-A-Dry cycle to follow.

The machine has a Rinse period then followed by a Spin period marked in "Danger - Will Robinson Red". So there are no spins between rinses. The spin is divided into two periods, one long spin with a minute tumble then back to spin to the dry cycle.

The dry cycle works on one set point marked by a small moon & bar symbol on the dial. The machine sits there drying until a predetermined set point is reached then the thermostat engages the timer motor again and the machine progresses to cycle end. 

This load took a little over 50 minutes to dry.

Enjoy and thanks for tuning in these past 5 months!
