Default Frigidaire - Motor shaft - to - Impeller
Brand: Frigidaire   Age: 5 - 10 years   

Appliance Parts from AppliancePartPros.com


I have a Frigidaire 650 Series, Model GLDB656JB0. It is not spraying water. I took it apart, and the water impeller is not being driven by the motor, which IS spinning. So, the attachment method between the motor shaft and the impeller is failed. I see no physical means for the impeller to be fastened to the shaft, except friction. Is this as it was designed? It seems like a very poor design. Will it work if I epoxy the shaft to the impeller? Any other ideas?

Disappointed in Beaverton....

Here are your parts.
Control panel replacement parts for FRIGIDAIRE GLDB656JB0 | AppliancePartsPros.com

Here is a manual
http://frigidaireservicetips.com/pdfs/485_3.pdf
Looks like it may well be a press fit.

If you look at page A-24 (in the manual), it shows the pump as a single unit whereas A-21 for a model in the same series shows a pump breakdown with a screw holding the impeller on.This looks like the parts breakdown at AppliancePartsPros.

If I then look up a GLDB656JB1 on AppliancePartsPros, it shows the single piece pump Item 70 at $124.73.

You would have to call or email AppliancePartsPros to find out what is going on. It is probably dependent of the revision of the unit, your unit may have the newer pump but they had not yet changed the revision number on the serial plate.

Hope I did not confuse the livin out of you with the above.

Denman - Thanks for looking into this. The part list doesn't show the part I need, which is a white plastic tube that the impeller mounts on. The white plastic tube accepts the motor shaft, and apparently uses only friction to transfer the rotation to the impeller. Anyway, I tried expoxying the motor shaft into the tube. It worked! ...... for awhile. The next step is to try to stick some abrasive material into the tube along with the shaft, to see if that will make it hold.

Default I have same problem!

Major,

I have the same exact problem. The motor shaft has a flat on it that is supposed to fit into the plastic sleeve which has a mating flat inside. If the plastic sleeve wears on the inside then the motor will turn but not the impeller I've been researching epoxy to use and found out that there is no good adhesive for the kind of plastic that is used for the plastic shaft. It's a nylon/delrin/teflon derivative and those plasics are impossible to glue - even with epoxy. Seems like the only solution is to buy the whole motor assembly just to get the plastic part. Bad design on Frigidaire's part.

So how did you solve your problem?

I'm wavering between buying the motor assembly and getting a new dishwasher. It's not like this unit is so great that I want to put a lot of money into it.

Bob - Thanks for your reply!

I tried wrapping the motor shaft with fine wire (thereby to increase the shaft diameter and fill the space between the shaft and the sleeve. That worked, but again only temporarily. The sleeve is cracked longitudinally, and the crack just widens to allow the increased-diameter motor shaft to spin eventually. In any event, it still doesn't work. I am just about resigned to getting a new motor assembly. I have seen them online for about $165. Compare that to $350 or so for a new comparable dishwasher. SHEEEESH.

I have been searching for a way to call the Frigidaire engineers directly to discuss this with them. Does anyone have contact information? Email or phone numbers? Come on... SOMEONE must work for Frigidaire who can actually provide some true customer service!!

I don't want to spend $165 or more when the only thing wrong is a 50-cent part!!

HELP!

For lack of a nail - the battle is lost. I'm looking at trying to fabricate another simple solution. Part of the problem is that the plastic part is part of the water seal. Mine is cracked longitudinaly like yours and was leaking. Were you getting any leaking. Anything I make that would take the place of it would have to also provide water seal.

Arrgh..

In the first reply above, Dedman suggested buying the motor for a GLDB656JB1 instead of the ....JB0, to save $. I tried this, but that motor does not fit the ....JB0 dishwasher, just in case someone is intending to try that. Not only does it not physically mount to the sump, but the connector on the dishwasher wire harness does not plug into the motor. .... grrrr.....

I'm trying to attach photos of the old failed motor + impeller assembly to show that how the cyllindrical shaft fits into the impeller. There isn't any more friction at all between the two.

But I have found the motor assembly for $114, at: www.us1internet.com/GLPB656JB).htm

I guess i'll try that now ... Still at Frigidaire Engineering. Does anyone have a phone number of email address for them?

Major,

Wrapped the motor shaft with teflon tape and some electrica tape. Pushed the plastic shaft back on and it was tight. reassembled and unit ran fine for a while but eventually loosened and started leaking and pump stopped working. I checked around and there's no good adhesive to bond the plastic shaft to the motor shaft ( consensus has that it's teflon which is near impossible to create bond with any adhesive). Got tired of washing dishes by hand and just bought a new unit. Couldn't find anyone to talk to at frigidaire/electrolux. You're not going to be able to buy the part, period. Since my unit was pushing 9 - 10 years decided to go with a mid range Kitchen Aid. Build quality of KA is far superior to the FG. For what it's worth I think that the plastic shaft is heat bonded to the motor shaft during assembly and once it's off - there's no reassembly. btw, the motor unit you have is made by emerson. Saw that in one of the repair guides that I downloaded ealier on this thread. Those units are drop-in but I've seen them going for about $200+ . Not worth fixing for that kind of dough.

Good luck anyway..
