I think I missed something....

Sorry guys, I think I missed something but I gotta ask...(our new system at work isn't working and I've been putting in a lot of OT to figure workarounds and haven't had the chance to follow this string like I would like to...) If the jet tower sits on a washington monument type of spike and is held perfectly centered by two jets of water....where does the "wash" water come from?

i remember seeing the salesman's video and he showed how you could just pull the tower out but never really covered where the water came from or how the tower turned.

I'm curious...

Jeff the water shoots through six large holes in the Jet-Tower support column and then it fans out throughout the Jet-Tower and comes through the tiny holes in the Jet-Tower causing it to turn.

Here is a picture of the support column (washington monument)with the Jet-Tower lifted out...

Robert,
Great pictures of the tub. I just can't get over how "gleaming" it is.
This machine is in such great shape!
Can't wait to hear the dishes go ouch!

Guessing Time...

Yes I'm very lucky the machine is in wonderful shape cosmetically. Last night I used my remote temperature sensor to measure the temperature of the incoming water. I mounted the senser to it was under the incoming stream of water from the fill flume but not touching the any part of the machine. It read as the water was filling in 181F, but once the tub had its full water level and the water valve had shut off, anyone care to guess what the temperature of the water being sprayed out of the Jet-Tower had dropped down to?

Hey Darrel, easy enough here is the picture of the underside of the Jet-Tube...

The faint blueness in action shots

1,2 & 5 is spectacular! How could the interior be so flawless if it had been used even slightly? The screen, the tub, the tower, the tube, the racks; no over "Chat" ing!
The tube shot is amazing. Did you clean all of those surfaces?
Is the tube quite heavy? It must be somewhat substantial to
avoid being forced off. I suppose the design of all the water
holes compensates for that. I'm looking forward to this video!
 
YAY! Glad the heater's working...will definitely help in the performance, IMHO...if 180 degrees doesn't do it I don't know what will! But even then, if the dishes are still a bit dirty after washing, you can always push & turn the dial again for another 9 minutes of washing until they're sparkling! I wonder if anybody ever thought to run the cycle a second time?

What is the temperature sensor? Are you using an infrared "point & shoot" thermometer to determine the water temprature?
 
Austin I'm using a good quality thermometer with a long wire that can go do and reach all the way into the dishwasher.

The answer is the water temperature comes out of the fill flume at 180F, but it drops down to 138F once its is being sprayed at full force and by the end of the five minutes of the wash cycle the temperature has dropped down to 129F.

"FEH", so if the temperature drops 50 degrees in five minutes, imagine what happens in dishwashers without a heating cycle. Shall we say not sanitized.
 
Do we forsee for the future a calorod heating element at the bottom, or is authenticity key?

At first I was going to say perhaps recirculating the water in the tub through the heating tank, but that gets complicated.....
 
Well obviously a towel can't be a solution to the leaking pump shaft seal forever, so now that I had a few fun washes in the Youngstown I took apart the pump again. Its a very bad sealing system, they simply compress a bronze washer against a bronze sleeve bearing. When I pressed out the bearing there was even water between the pump base and bearing tube, oy.

The bearing is worn, so tomorrow I'm going to take this bronze sleeve bearing (or bushing) down to my local bearing retailer and see if they can match it up with a new one. I'm keeping my fingers crossed that its a standard bearing.

Here are the parts of the pump...

Check out the size of this impeller shown next to a mix-master for size comparison, its meant to move a lot of water and the motor turns it at 3450rpm!

Well at Gopher Bearing yesterday I found the EXACT replacement sleeve bearing for the Youngstown's pump body. I installed the new bearing in the pump housing and it makes the dishwasher a bit quieter as the old bearing was worn down a bit. But unfortunately I still have a very slow Drip.....Drip.....Drip (one drip every five minutes) from the pump shaft. So down goes a towel until I can locate a good substitute for the pump seal. Back to the old drawing board.
 
pump seal

I was trying to imagine how they got a good seal out of all metal parts, with no O rings or such.
