GE dishwasher lies...

Ooooph. Ooooph. This might be record for dumbest thread I’ve read yet.

Yes the GE brush motors suck in the sense their shaft seals were bad.
Not so much the brushes.
My parents and I both had GE brush motor dishwashers and they both leaked at the shaft seal.
My parents’ base cabinets were even ruined by it for leaking for years before noticing.

The wet rotor motors are far superior and leak free.
Haier moved GE dishwashers to wet rotors. It’s the one positive thing Haier did!

Even Frigidaire has done away with the old brushed Johnson motors.
They both switched to brushed motors around the same time, when Elux was trying to buy GE Appliances, probably trying to consolidate supply chains before the sale.

The brushes don't last forever, they literally have a guaranteed finite life expectancy. As the brushes press against the slotted commutator rotating at thousands of RPMs the brushes are literally shaved and ground down steadily becoming shorter.  After a few thousand hours (at best) the brushes become to short to reach the commutator and the motor stops working, often after severe arcing / sputtering pits, burns, glazes and damages the commutator teeth.  

 

 

Brushed motors are only practical where high RPM, small in size, light in weight motors are required at short run time intervals. Hair dryers, coffee grinders, drills, mixers, hand held tools, vacuum cleaner, toys ect. Another application is precise speed control under varying torque loads (where AC motor slip will not do it) like sowing machines and conveyors. In the past where AC was not available like RVs and solar was another driver for brushed motors, though that is becoming a thing of the past with variable frequency drives. 

 

 

None of these apply to a dishwasher.

Well, the brushes in my parents’ GE lasted at least 8 years, so there’s that.
It was the pump seal that gave out first.

You’re tilting at windmills at this point, since the brushes motors are out and wet rotors are now in.

I'm glad that GE uses a wet magnetic rotor motor for their wash pump in the builder grade dishwasher so I don't have to hear that stupid shrieking, but I miss the real AC induction motors they used for years.

 

[Chetlaham]

I miss the induction motors too.

 

Personally I think a precision built PSC motor on a Whirlpool Power Clean Filter Module would be the best sounding.

I agree. I miss the rock band sound of the GE filter-flo washer's normal speed agitation too. As for the dishwasher, I remember it sounded like a copy machine while it was washing due to that rhythmic spraying against the door.

Would you like to bet part number 807473201 and the following thread?

You're calling for a ban when the information you're posting is blatantly false. Frigidaire and GE have been using brushed motors for years. Take one apart and then come back to me.

Better yet, listen to one in operation. How about that?
