I see the last expert has OPTED out .
I will try to assist you ,But I will ask you some questions first to properly diagnosis the unit .
Before I Just start having you ((throw )) parts at it .
When the unit is done filling with water ,can you open the door and tell me how much water is standing in the bottom of the unit
You can set it on any cycle it fills with the same amount of water no matter what cycle it is set on .
Normal fill is just touching the heating element .
LOL and no problem , most homeowners are the same just put dishes in ,detergent start and walk away .
ok good ,water volume is ok .
Now lets take 2 coffee cups NOT mugs , and set them on the top shelf one on the left and one on the right ,in the center from front to back ,setting up right ,so as to catch the water .
and then close the door let it run for 60 seconds ,and then open the door and tell me how much water is in each cup ?
no that will work for this test as long as they where upright .
Ok so the unit fills up with the correct amount of water ,you have a new upper spray arm and the manifold .
The only thing you have is the wash impellor in the pump ,it may look ok but if it is worn it will not pump the proper volume of water ,
Here is a link to the part .
no problem ,let me know how you come out.
and remmber my accept not the last expert if this works !!
Hi. I'm Smitty. I am a professional appliance repair consultant here to help you diagnose, and repair, your appliance.
This may seeem l;ike a dumb question, but are you sure that the unit is pumping any water at all through the spray arms? Upper or lower?
Try the coffee cup trick on the lower rack. Let me know what happens.
Ok let me dig into the service manual and see what I can come up with. It sounds like a blockage somewhere.
Give me about 15 minuets, please.
Here is a possibility. Not too lilkely but it is posible that this filter is plugged.
Ok. If that is not the problem, and you have replaced the impellar, and other parts mentioned here then that leaves a motor that just is not turning fast enough to push the water up to the top sprayer. Either that or the impellar is spinning on the drive shaft of the motor.
Now mind you that any leaks, misfitting docks, or misaligned delivery tubes will leak a lot and reduce the pressure enough to cause this.
Give me one more minuet and I will see if there is a test for the motor speed.
Please click here to download th etwech sheet for your unit. It has the test specs for th emotor as well as other components.
When measured the motor should have between 3 - 4 ohms resistance.
When I was doing automotive diagnostics and had a vehicle that I had trouble figuring out, knowing good and well that I had done every test, in the correct sequence, at the prescribed temperature, by the book, etc., consulted with the other mechanics on the floor, ran all possibilities past the service manager, and still could not come up with a solution I did one thing that (except for one time) worked perfectly.
I put everything back the way it was and started from the begining. By the book, no skipped steps, no shortcuts, no 'Eh, I already checked that three times', etc.
From point A to point Z, in order, by the book.
If that doesn't work then do like I did and throw a 13/16" combo wrench acrost the shop and shout an expletive loud enough that the whole shop can hear...... Well, on second thought, don't do like I did. Have someone else look at it. Sometimes we just cant see the trees because we have been stairing at the forest too long.
That one I couldnt figure out.... The Matco Tool man walked over, picked up my wrench, politely handed it back and asked what the problem was. I told him everything I tried. He then picked up the same wrench. Tapped the mass airflow sensor and the damn thing hickupped. Tapped it again. Hiccup. Problem solved.
