Question about Whirlpool Dishwashers

1 Answer

Model GU1500XTLB1, type-575-0. Why is upper arm and assembly not getting enough water pressure to spin and clean?

The unit spins freely by hand. The bottom assembly seems to be working. Absolutely no clogs in the upper or lower spinner.

SOURCE: 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. Catriver..post back

SOURCE: water not spraying hard enough

Could be a a couple different issues.. Not filling with enough water or food chopper broke or food chopper filter screen clogged.

Check water level:
Run the DW and wait for the main wash to start (water will fill. pause then complete fill) The water should be no more than 1/4 inch below the heating element. If not there..replace water inlet valve.

Inspect food chopper:
Remove lower spray arm and rear water supply tube to upper spray arm. Remove torx screws that secure the sump cover. Remove the rounded cover on the left side to expose the chopper assembly. Inspect for breakage of blockage. There may be an additional plastic screen to remove first.

SOURCE: I have a Frigidaire Ultra

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.

SOURCE: Wash Arms not spinning --Dishes not clean

Without the model number of your Maytag number, I can not determine if when you order a wash pump motor you also get the impeller.
Sounds like you are on the right path to getting your dishwasher to wash dishes again.
Oh, while you have the dishwasher open, check that the heating element has not failed using a Multimeter.

Good Luck!

R1200GS - Starter does kick in, turns the enjin a few times and then seems like it slips and the starter motor turns freely.


Your starter bendix possibly needs cleaning. Unfortunately these are sealed units and can only be dismantled and re-assembled with specialized equipment. They can be purchased loose.

Have a look here: Starting

This is the part you are looking for:

Top blades Will Not Spin


Hi - I will suggest verifying that there is enough water pressure coming into the unit. When was the last time the filter was cleaned? Do you noticed if the spray arm will rotate freely or if it is damaged? If so, you might have to remove and replace the spray arm assemblies. If any proves to be ineffective, it could possibly have a communication problem coming from the main control board, I would suggest contacting a professional technician to diagnose the unit accurately.

Upper arm does not spin


If the sprayer arms continues to get caught, see if your racks can be adjusted in height. Some can be moved up or down by the side brackets. Otherwise freely spin it with the unit off and see if it is just getting caught on a pot/pan in the unit. Otherwise, it may not be getting enough water pressure to turn it completely around.

Top spray arm does not turn during wash or turns slightly..it is free of clogs and spins freely by hand


It will spin freely by hand, but needs to spray water out of the jets at the trailing edge of the arm. Check inside the arm for blockage and make sure that water is getting to the upper arm from the pump.

The upper arm is free spinning by hand, but from all indications, it is not spinning. Water is flowing freely and drain is excellent. Is the upper arm problem a major repair.


Hi


Please check if something is blocked near the top spray arm, also make sure that all holes are oopen. Use a sharp metal pin to clean the holes on the top spray arm. Make sure the water pressure is not low.

under the screen and youl'll need a Torx driver to get to it after you remove the spray arm and screen. Check to see that the path it travels is clear. I have seen these get blocked up by stuff.

Now check if the top arm spins freely and check the bearings for the arm, if they are producing extra friction while the spray arm spins. Hope this helps... Please post back if you need more assistance.

Top wash arm doesn't spin.


Hi,

This is usually due to restrictions from debris in the sump area of the pump, it will not allow enough pressure from the pump to spin the upper arms. I have put together some instructions on cleaning this on your model, follow the link below and let me know if it was helpful.

Whirlpool 6600 24 inch dishwasher: low pressure,arms not spinning


Your water pump is blocked. You will need to either call a repair person or disassemble the top of the pump (inside the dishwasher, bottom) and check the water input duct. It just might be some food, etc.. that is blocking the input. But if you don't see anything then it will be further inside and will need to be removed and cleaned. BIG pain...

Best of luck. BTW, I've had the exact same problem but mine was further inside so I had to remove the whole dang pump, arggggggg.

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
