Hi all, first I must say I am thankful for this forum. I have already learned alot just reading.

Now on to my issue. The dishwasher is 2 years old. The kids were complaining about it not getting dishes clean anymore. I usually check the filters first, clean them and go on.

This time the round fine particle filter was halfway out and there is no telling how long it had been run that way. Upon further inspection the spray arms were 35% clogged with food. I took those out and cleaned them completely.

After replacing everything and cleaning out from under the filters and under the diverter motor cover and plate I ran it through a cycle or 2. The lower spray arm is not spinning at all. Does this model have a motor driven lower spray arm or no? It spins freely when spun by hand.

I tried to run the diagnostic cycle on it but it wasn't much help, there is no display to display any codes. It plays a tone and it's so faint I missed it. The lights on the control panel light up but you can't see them with the door shut so how do I retrieve codes from this model. I'm hoping it's a stuck diverter motor.

Can you guys help? Thanks in advance.

No it doesn't.

Here's the tech. data sheet for your model: https://drive.google.com/file/d/1Orlfy89qQEfjZiiJxdq6HteYlwF0a5yO/view?usp=sharing

Lets first check and make sure the diverter plate is aligned and "snapped"/locked in place. A jalapeno seed or something stuck inside of it may be keeping the diverter motor from rotating the diverter plate disc, which makes the water divert to the upper spray arm and not the lower spray arm.

Thus, the diverter disc MAYBE sliding up the shaft while the unit is running. This gives it just enough space to slide off it's groove.

Watch this video below, it shows you how it slides on the shaft.

If the diverter disc is fine, these wash motors are very common to go bad and cause this problem you are now having.

After it fills the wash motor should come on and you should hear water splashing in the tub, if not then It's most likely a bad wash motor, this has become a common problem as of late, many members here have reported the same. In fact I had 2 this past Sept. 2018 in Parker, Arizona that did the exact same thing, and the new wash motor fixed them both.:)

Look at post #7 here: FIXED 665.13472N411 What to check on why it only washes about 5% of the cycle.

I'd first check to see if your getting 120 volts to the wash motor when it should be in the wash cycle.

Take the wire connector off the wash motor and use a multimeter to see if yours is getting 120 volts when it should be washing, if so and it's not running order the wash motor below.

Here's the wash motor for your model you can order: W10894668

This video gives you the general idea of how to remove and replace the washer motor:

Let us know how it goes.

Thanks Jake, after the cleaning and running a few empty cycles it seems to have resolved.

One question though. I did remove the diverter disk and it has a groove cut in it where it can only slide onto the shaft in a certain orientation. I did not notice a "snapping" when I pit it back in place. It sort of just fell down onto the shaft.

Should I disassemble and pres the disk until it snaps onto the shaft?

My bad, I meant slides onto the diverter motor shaft, don't know why i said snaps onto the shaft.

Glad to hear your back in business.(y)

Thanks for the update!
