Question about Whirlpool GU2400XTPS Built-in Dishwasher

1 Answer

I replaced the spray arm seal, but the arm still wont spin. I get water but not enough pressure to turn the top arm. The bottom arm works fine. Should the top arm turn easily when pushed by hand. It appears that it is not tight even though the screw is secure.

Arms should turn freely. spray arms are only rotated by water spraying out from angled jets at end. check for blockage in spray arms - sweet corn and rice are the worst offenders. take spray arms off and run water in centre hole and see it runs out of all the jets freely

Hi Mark,

Have you checked the seal/gasket on back of the upper spray arm assembly?

If you pull the upper basket forward the entire spray arm assemble will come with it. You can remove the spray arm assembly by releasing the single clip at the top at the rear of the basket. The spray arm assembly with then slide out backwards.

Once you've removed it, have a look at the back of it. There is a plastic gasket inside with 2 holes which fit over the studs at the top of the delivery tube still attached to the back of the dishwasher.
You can remove the back cover of the spray arm assembly by releasing the 2 clips at the top and bottom. Be careful here as they may be brittle after prolonged use of the washer.

Remove the back cover and take the plastic gasket out. Place the holes of the plastic gasket over the studs on the delivery arm in the back of the washer and check the gap between the gasket holes and the studs and check for excess movement.

If there is a significant gap or movement here, then it needs to be replaced. If there isn't a reasonable seal at this location, water will leak from there and there may not be enough pressure to rotate the spray arm

If you've already done this or there seems to be no problem with the gasket, please let me know and I will try to assist you further. Similarly, if this proves to be the problem and you need assistance obtaining replacement part/s, just let me know.

Hope this helps.

try starting the washer, then opening to door and checking the water level in the bottom of the machine, as far as I know, there should be enough water there to disolve the tablet when it sits in the bottom. if not that much, bung in a few cupfulls and you should see the pressure dramatically increase!

Kenmore Elite Ultra Wash Dishwasher - top rack arm not spinning

Hi: I just posted a similar problem, but found a solution. After taking the arm, etc. apart (and verifying no blockages), I thought maybe the lack of water pressure was being caused by the fact that there are TWO holes for the top spray arm (higher and lower rack setting) on my model. ie. that water was being forced out of both holes, causing a drop in water pressure, which was causing the top spray arm to stop spinning. I plugged the unused hole with a wine bottle cork (to keep the water from spraying out the unused hole), and voila, it now works.

I wish all appliance fixes were this easy...!

I have a Frigidaire Ultra Quiet Plus dishwasher. The top spray arm isn't spinning during wash. The bottom spins fine and I can spin the top freely by hand. It appears there is not enough water pressure...

I may have the answer. I had what sounded to be the same problem. I found the dishes were dirty after they were cleaned, but I found there may have been a big pot lid blocking the upper arm. I decided to run the machine again, and after a bit opened the dishwasher after to make sure it was not a problem with the arm. Sure enough, the arm wasn't moving. However, I found out on the Frigidaire webpage that some models have an alternating spray cycle, where only one arm spins at any given time. After reading this I checked again, and it had moved by that time. I checked a few times more to confirm this. So it ended up it was an arm blockage after all. Hope this helped...good luck.

Top arm not spinning

only the top rack isnt getting clean?
there is a little plastic circle in the middle of the bottom of the upper spray arm. turn it counter clock wise to pull the upper spray arm from the upper rack. make sure that isnt clogged and the spray holes are not clogged. otherwise....

the piece that the bottem spray arm plugs into and runs along the back wall of the tank to the top is called a feed tube. pull the bottom spray arm out. now you can see the part of the feed tube that feeds the upper spray arm water. does it pop out freely and easily? if so then you need a new feed tube, if not then its most likely your not achieving the right water level or your impeller connected to your circulation pump(motor) is clogged not supplying enough water pressure to travel up the feed tube to spin the upper spray arm.

Top Arm not spinning on Whirlpool DU1145

It looks like there is not enough water pressure to spin the spray arms. Loss of pressure may be due to various things, like damaged seal, cracked tubes, clogged filters, screens etc.
I suggest you take a look at the technician repair sheet that should be stored inside the front panel at the bottom of the door. Remove that panel under the door with screw driver. Inside, attached to the panel, you should find a troubleshooting guide and solution for technician. But it is easy to follow. Look at the section under "poor wash" and follow its recommendation. I had exact same problem - not enough water pressure. In my case, the chopper screen was clogged and the chopper assemply was broken. I followed the repair instruction above to remove the chopper assembly, cleaned the chopper screen and the washer now is as good as new. I will need to replace the chopper when the part arrives.
Good Luck

Bottom wash arm

there is a blockage but may not be obvious. arm turns only by water spraying out of the angled jets at the end of the arm. take arm off, run water thro the centre hole and this is udually enough to force the debris to the jets. clean out and check

Small plastic top and mid spray arm do not turn, bottom does

decrete, you want to get down to the chopper and screen. If the screen is plugged up with gunk there won't be enough pressure to reach the top spray arms. Check out the posted pics. Remove the lower spray arm. Rotate the rear feed arm to the right until it unsnaps from the tube going up the back. See the 4 torq screws holding the filter on. Remove them. Lift the filter up. Now you will see the chopper inlet cover. 1 torq screw holding it in. Lift it up and there's the chopper and screen. back
