Top Arm not spinning on Whirlpool DU1145

Hi

As you have already cleaned and checked the arm for any clogs then please make sure that all holes are open. Use a sharp metal pin to clean the holes on the top spray arm. Make sure the water pressure is not low. The top arm spins freely. If not then check the bearings for the arm. Hope this helps...please post back for further assistance.

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.

Hello bue.... The top arm spins due to water pressure. pull your top drawer out and inspect the rubber tube that feeds water to the top arm. Usually they have a split in them so the water does not get to the arm to spin it. The fix is to replace that rubber tube. You will need the model number of your machine to order the correct part. I usually get my dishwasher parts from searspartsdirect.com

Hi

Please check if something is blocked near the top spray arm, also make sure that all holes are open. 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 you'll need a Torx screwdriver 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.

its just clipped over the cap remove and clean also check the seal is not damages on the pipe that goes into case.

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 pump cleaning

I do not have a problem w/the upper arm not spinning. Rather, the upper arm keeps falling off of my frigidair dishwasher. The owner's manual suggests the upper arm is a single unit. However, the upper arm component is comprised of 3 parts. The parts are an arm that distributes the water, the base that screws to the top of the dishwasher, and a small plastic type washer that rides in the base and literally holds the arm to the base. The plastic washer has two small clips that tend to wear or contrast with age; thus letting the arm fall off on a very frequent basis.

Potentially, the small plastic washer piece may have broken in the base assembly and is not allowing the arm to turn. As water flows into the arm from a hole in the base; suggesting the plastic washer may be jammed with a foreign item seems less likely. The base unit screws to the top of the dishwasher and can be removed by hand (the base is a little tight). There are no mechanical pieces to my third (upper) arm; movement of the arm is accomplished with water flow.

You may wish to remove the arm assembly and check for a broken washer or a foreign item in the assembly. As a side note, I found that I can unscrew the base and remove the assembly without removing the top dish tray. The fit is a little tight but the tedium of pulling and reinstalling the top tray can be eliminated by unscrewing the assembly w/the tray slid forward for assembly access.

Hope all you have is a foreign item that is locking the washer.

Clean the filter at the bottom of the tub. If it is dirty or clogged the water pressure may not be strong enough to spin the top arm. Make sure also the there is nothing blocking the holes of the spinner arm. If the filter and arm are clear then the pump may be failing.

check seal to upper spraybar pipe if all complete.
Check your rack setup for possible blockage

sound like a low water level and or pressure issue. Start machine on normal cycle after filling open door and ck water level. should be up toJUST below heater assy.. assumiong htats good set hte wash arms to a set positon so you can watch for rotation. close the door adn after a few secs open rapidly and look for middle arm to be spinning, even the top 3rd row arm if present, should be spinning spinning . if not its possible that the motor/sumo assy is blocked w/ foriegn debris. remove the lower spray arm (hold the nut and spin arm)then remove 4 or 5 torx 15 screws. probly pretty glogged under there. if not id look into replacing motor sump assy/seals worn and not throwing water where it should go
