1958 Frigidaire spin tube dishwasher
Hi Christopher, looks like a fun project probably the easiest way to remove the minerals from the heating element is sandpaper, it’s so baked on that most chemical cleaners probably won’t do much to remove it, it also won’t hurt anything if you want to leave it.
The door gasket may or may not leak there’s really not much water directed forward in this dishwasher toward the door Need a picture of the door switch this uses in most cases the door switch like that usually Hass to be replaced but you can try spraying some silicone lubricant into it and see if it works afterwards Keep us posted as to how well this works out. John. | ||

Is the door switch stuck in on position? If so at least you can still test the dishwasher. That door switch should be simple to find simply google "120 volt microswitch". I found one on Amazon but it is a bit expensive... amzn.to/3ldzGpP...
For the door gasket simply go to Ace Hardware or Home Depot and get a strip of closed cell foam self-sticking weather-stripping that you place right on top of the old gasket. | ||

Fixed the switch or at least got it moving. Everything is wired up and ready to hook up water and test it! Still need to clean it tho - pretty dirty and rust spots. Even the chrome has pitting. If it works well it might be worth fixing all that…..later haha | ||

More than likely the pump impeller is probably just stuck preventing the motor from turning. The pump may need some very hot water poured through it and then you may be able to loosen it so it turns. Careful though as I believe that impeller is made of Bakelite so it could break if you use a sharp instrument to try and get it to turn.

Sounds like then the internal start centrifugal switch of the motor is stuck and needs some cleaning and lubrication which means you will need to take the motor apart and investigate. I suspect the start switch is near the top of the motor which means you will need to carefully remove the impeller which is probably stuck on the shaft. You can test the motor by taking the two wires off the connections and place a test electrical cord onto the two wires and plug the cord in to see if the motor turns or not.

Anyone aware of any resources or videos to take a similar type of motor apart by chance? Not sure what I’m doing or looking for ( going in blind!). | ||

Took the motor bottom off. I could use guidance - what next/ what am I looking at? | ||

Likely shorted, grounded motor windings
From your pictures and your testing it looks like you have some grounded shorted motor windings to start windings look particularly bad.
If you can find another motor or get a motor shop to rewind it, it might be fixable. This would not have damaged the timer and there’s no electronics of course to damage in this dishwasher lol. John. | ||

Advance Electric
I have used this place about 10 years ago and they did a great job and also had a lot of vintage motor parts on hand.

$450 to rewind the motor seems steep, but that's just me.
I'm sure these motors aren't just sitting on shelves anymore but it may pay to look around just in case. Maybe give these people a call without mentioning your first price quote and ask what they would charge for repair. I also checked with Conrey once and they were very helpful. It's always good to get more than one quote! CLICK HERE TO GO TO pdub's LINK | ||

That's great news Christopher. I want to take a Frigidaire Unimatic washer motor in to have rewound and I too am expecting the price of a rewind to be much higher than when I had an Apex dishwasher motor rewound about 15 years ago.
Hopefully your shaft seal is good, there should be a generic number on that seal. | ||

When you say the shaft seal is leaking, how do you know it is the shaft seal? Is water dripping out from the bottom of the motor or down the sides of the motor?
These Frigidaire dishwashers use an impeller that is threaded onto the motor shaft, but according to the manual it is a left-hand thread which means turns clockwise to remove. The shaft seal is shown here with a red box around it...

Bumping this. I still the a source for at least one “flange screw and stud” to hang the motor. One of mine snapped off. Many thanks. | ||

Here is what I have
I have this motor/pump/timer assembly from a dishmobile that I stripped down to keep my pristine custom imperial undercounter spin-tube in operation for many more years.
If one of the bolts of this will work for you, just point to the one you want and I will mail it to you

Can you take a photo of the washer you're referring to and the seal once you get it out? I would examine the seal for any crack in the rubber bellows part of the seal, if all is okay it may be leaking between the pump housing and the outer section of the seal. A little bit of cleaning and fresh silicone may solve that if that is where it is leaking from. Gentle cleaning of the sealing rings may help as well.

It looks like the bronze washer on the impeller is identical to the washer used on the Pulsamatic/Multimatic/Rollermatic pumps, the 5433973 "Washer - Pump seal", and boot seal assembly looks similar to a standard dishwasher seal.
If there was a way to convert the bronze washer over a ceramic washer, I wouldn't be surprised if a seal for a KitchenAid 15-21 series pump would fit in the motor housing. GM Frigidaire did have a conversion kit for these, that would update the washer to ceramic, and updated the impeller as well (full conversion kit - 6591902, last updated seal assembly was 6597961).

Thankfully you won't need to create a seal yourself. You more than likely can retrofit a later, more modern seal assembly in place. AFAIK, you can't intermix a boot seal designed for a bronze washer with a ceramic washer, so both need to be swapped out (thus, the Frigidaire kit above). Take a look at the two seal kits below:
This kit is for a 70's Whirlpool. The boot base diameter looks similar to the cast iron full opening for the pump, and the shaft opening also appears to be the right size (I imagine it's 5/16" or 3/8"). The ceramic washer is loose from the impeller (this is good for you) and if the diameter is close to the opening on your impeller, I bet you can use a good RTV silicone sealant to set it in place. https://www.ebay.com/itm/192800170771... This next kit is for a mid 1960's through mid 1970's 15-17 series KitchenAid, that also is mostly similar to an 18-20 series machine. Notice the ceramic washer is imbedded into the rubber impeller, but the boot seal is similar to the Whirlpool. https://www.ebay.com/itm/334468378276... This will take a bit of investigation on your part, but for the most part I think you'll be able to take a kit that is similar to the Whirlpool and make it work for your Frigidaire. When you do end up making this fix, make sure to pull out all old, carbonized rubber and clean up all surfaces as clean as possible. I'd also recommend using RTV on both the impeller side AND the pump base side to ensure a good and proper seal. You may also want to install a o-ring around the shaft to ensure that water doesn't enter the threads of the shaft if the seal became compromised. Ben | ||

Hi Christopher, just get yourself a water valve rebuild kit here at the link below. You also might want to soak the brass valve body in Lime-Away to remove any scale that might be in the metal parts.
