2005 GE Nautilus dishwasher

GE dishwashers

My dad has a GE dishwasher with what they called dry boost. It does the alternating wash arm action, and you don't hear a motor whine, which is more of a motor hum. I think it uses a different wash pump.

 

[Chetlaham]

Do you remember the model #? I know GE dishwashers that whined tended to use those dreaded brush motors which would quickly wear out. Brushed motors are not for appliances except maybe hair dryers where an induction motor would be to heavy. My Super Salano hair dryer box has the universal motor life listed at 1,500 hours. Thats to low for anything. A good DW motor should be able to last well beyond 10,000 hours. Induction or wet rotor permanent magnet is the way to go.    

 

 

My personal preference is for across the line induction motors and running all wash arms at once. What do you prefer if I may ask?

If the part #s are telling me anything its a brushed wash motor:

that motor is brushed dc and very similar to that used in later model Frigidaire dishwashers: permanent magnet with rectifier built into motor.I saved one of these motors from a FD dishwasher that was junked after a year of service because the(about 100% fail rate)door switch was bad...An easy fix but the dishwasher was all greasy and grubby from improper usage and a cheapie so i junked it.

brushed motor

I didn't know that GE's builder grade dishwashers used a brushed motor. The youtube short of the Hotpoint version I showed you didn't have that high-pitch noise. It sounds like it has an electrical hum more than a scream when running.

 

[Chetlaham]

I don't know about the BOLs, but MOL and TOLs used those motors and they still might. I haven't been keeping tabs though, nothing about the current GE fleet catches my eyes. 

 

If I was the engineers at GE and had to build a tall tub I'd simply stick two or three of these underneath. One or two for the wash arms, and one for the drain. All 3 would be the same 85 watt pumps- either wet rotor or those Italian style washer pumps used by GE.

 

 

 

 

Cycle and wiring diagram like this, none of that electronic nonsense:

wash motor

I suspect the wash motor is a wet magnetic pump based on the sound it made. Did you see that youtube short?

GE flimsy

The new GE tall tubs that replaced their standard tubs including their Nautilus line felt as cheap as they come. I could just picture the racks falling down and crashing onto dishes.

Chet that shows why you’re not an engineer that is a drain pump it would not begin to wash dishes and it would make so much noise. It would be ridiculous. Drain pumps like the one you pictured are made to pass foreign objects. They’re very crude. They use a lot of power for what they do. They don’t provide the pressure that you would need to wash dishes.

You can go back and play in your sandbox and your world of make-believe but many of your posts are just ridiculous.

John, your post above is an example of denigration. The same abusive behavior other member have called you out on, repeatedly.

 

 

I'm well aware I posted a wet rotor (Model T/Hydrowave) washing machine drain pump, one where the body and impeller can be easily re-engineered providing the desired pressure and water volume to an engineered spray arm. Shaded pole or PM 60Hz AC motor - same 85 watt target goal.

 

I'm not concerned about energy efficiency. The best cleaning dishwasher, the one which cleaned phenomenally in the corners in this real world, did fine with an inefficient motor.  

 

 

So as your posts sits it adds nothing of value or substance to the discussion. Other than to instigate derision and tear down other members while making baseless insinuations.

 

Stop acting like a kid in a sandbox.

Seriously?

John, seriously? So you're telling me that anything Whirlpool is superior? I don't think so. I think Speed Queen is superior to anybody else. If Speed Queen built dishwashers, it will have a real pump and motor system and a hidden heating element and heated fan drying.
So tell me, what wash pumps do today's GE builder-grade dishwashers use? They sure sound like wet magnetic motors to me.

directional wet rotor PM wash motor.

do not recall what brand,but i salvaged a wet rotor wash pump at the dump and it had electronic circutry to make the motor run same direction every time and a directional impeller and volute was used.

 

[Chetlaham]

@cfz: I'd rather deal with the inefficiencies of a directionless wet rotor or a shaded pole motor in any dishwasher than the complexity that comes with electronic ones. Let alone a short life brush motor.

 

Unfortunately John used that point to say I would be applying unaltered Hanny drain pumps to dishwashers, those specific pumps aren't even designed to run continuously let alone handle 185*F water continuously- twisting my post in front of 5 blocked members further driving John's divide and conquer strategy.

 

@GELAundry, If Speed Queen made dishwashers they would be like the Whirlpool power cleans with a self cleaning fine filter, vetical mechanism and 1/3 HP relay start motor. That design takes up space and makes noise, unfortunately not many customers would buy that already preferring tall-tubs.

chetleham: Here's some who's blocking you because of your lack of respect for other members!

Speed Queen Tall Tub

If there were Speed Queen Tall Tub dishwashers, the sump would be deep and the pump intake would be in the very bottom so no matter how much water is in the machine, there would be little to no cavitation even if the tub floor isn't completely covered in water. Ideally, the perfect water level would be above the disposal cover. It would be nice if Speed Queen Tall Tubs could have a foot of water filling the entire basin of the dishwasher for maximum constant pressure to spray down the dishes and door with massive walls of water with massive spray arms full of jets. That would be the ideal tall tub dishwasher.

@luxflairguy: Nicely asking a bully to stop bullying isn't a lack of respect. Calling out a bully isn't a lack of respect either.  

 

 

If you want to be one on the wrong side of history justifying John's behavior have at it.

 

[gelaundry4ever]

I agree with Chetlaham.

I agree with you Chetlaham. If you don't confront the bully or report him or her, he or she will continue.

Here we go again....

....the same gangster members intent on conquer and divide tactics with their schoolgirl taunts of vile and toxic hate. For what????I would suggest that each of us as members takes a moment to read POST #845122 along with Topics & Rules and re-familiar ourselves with the doctrines and purpose of the AutomaticWasher.Org website before our webmaster makes a clean sweep of the troublemakers and suspends or better yet bans the accounts of offending members.
