Frigidaire ultra quiet III Dishwasher whistling

[Techno55]

Hey I forgot to say thanks, I bought the Dishwasher motor, it came with everything included the 15 inches diameter plastic base (why?), the motor, gaskets etc and worked (of course) I think it is expensive $130

Now is the freaking timer motor assembly... it locks sometimes in one place it is exacltly 180 degres from the start position...Grrrr

Thanks

Did we ask how old this dishwasher is? I am thinking in terms of how much money you should put into a DW if it is more than 7 or 8 years.

As to why you had to purchase a large assembly, as opposed just the motor: two reasons.

Service would be too expensive if customers had to pay the labor cost of disassembly and repair to the small part level. AND, a service man is not going to warrant a pump assembly full of old parts while just replacing the motor.

That kit replaces several different pump motors from different manufactures which have been used in production. In order to install the current motor, a new housing is usually required as well. They ship 2 housings because models could use one or the other depending on the dishwasher's features.

The kit was made available due to complaints from field service depots which before then had to stock 3-4 different motors and a bunch of different housings in order to complete repair jobs on the first trip. A single motor kit that would fit all, reduced servicer's inventory making it easier for repairs to be completed quickly which is more cost effective to the servicer and preferred by customers.

it locks sometimes in one place it is exactly 180 degrees from the start position.

Unless something fell into the pump and is jamming it (unlikely IMO), I can't think of anything besides a defective motor which would cause it.

It's probably not what you want to hear but the replacement motor should be warranted for 1-year so you'll likely need to order and install a replacement and return that one.

Kinda late for that now (seeing the part has been purchased and all) but that model only looks to be a 2000 or later. I could tell for sure with its serial number. Being that it's a non-electronic control model, there isn't a lot to go wrong with that particular design and it's new enough that it should be reasonably thrifty with water consumption. I don't believe just a motor replacement is unreasonable unless it was a very bottom of the line model and/or there were other problems like the racks rusting, timer not advancing or malfunctioning, etc.

I've just uncovered the same problem with a slipping shaft, complete with the same cracks in the barrel as you picture. Note the impeller clips onto the shaft, the stainless screw on the end keeps the clip from compressing. Pinch the end of the shaft with fingertips or small pliers and the impeller will slid off and the whole unit can be disassembled.

I've yet to find if I can order just the shaft, everything I've found on the web doesn't break this part out. I've a good appliance parts store in town that I hope can help me with this. I'll relay any info I find. An apparent weak design that likely causes lots of problems. The unit hasn't been cleaning too well lately, probably has been slipping to some degree for awhile.

BTW, I do see the splines on the motor shaft in the picture, they're just very close to the motor housing.
