Question about Whirlpool GU2400XTP Built-in Dishwasher

1 Answer

Component failure Actually a Kuppersbusch IGV 645.2 Dishwasher There is a plastic conduit which takes water from the base of the machine to the upper spray arm. This now comes adrift from its connection at the base (behind the lower spray arm) on every cycle, resulting in poor or incomplete washing. It can be replaced easily and seems firmly inserted when done but is always adrift again by the end of the next cycle. Anyone any ideas?

Re: Component failure

Put a bead of silicone on the tube connection and let it set up good before running. If the tube is in good shape and only comes loose this should be an easy fix.

I have a very old Kuppersbusch dishwasher - UG632 and I suspect the float has either stuck or has broken. I have no idea where it is however in order to check. Can you please advise.?

If it has a float, which is rather unlikely, it will be below the floor strainer at the bottom of the machine. Most machines use a pressure switch which senses the level of the water through pressure sensed by a diaphragm. This is located out of the washer area and is connected to the water pan by a plastic pipe.

The top rack dishes are not getting clean. the spra arm is clear and the tube supplying water to the arm is clean. the float is also moving freely.

does this have the water conduit tube going up the inside of the rear wall where you can see it,if so,the conduit "horn" where it connects to the tube that feeds water to the upper arm with repeatedly opening and closing this horn wears out and lets water get past here and lowers water pressure to the upper arm

The top rack of dishes are not getting clean. I

you need to check the upper wash arm for blockage from debris,if this is not the case,then you need to replace the water conduit from the lower sump area to the top arm,after time the water erodes the plastic conduit especially where it connects at the arms and water gets by these areas and can no longer build pressure to spin the wash arm

Water not getting to upper wash arm / glasses on top rack are dirty after the cycle - I do not know how to take out top slide basket to check water flow in tube at rear of machine-

remove the roller rack plastic end caps this will let you remove the upper rack,then you can replace the whole wash conduit from the bottom sump all the way to the top,also if theres a middle(center arm) this has a horn on it that is to seal when the rack and door are in and closed,but after while the water wears out the plastic o-ring and they leak and you lose water pressure to the top wash arm

Bosch SHU 8805 upper arm is getting no water.

replace the upper water arm conduit and wash arm hub as they leak under years of pressure and the o-rings leak water and then it can't hold pressure and supply the upper arm with full pressure water,also replace the center arm conduit if it has one as this will wear out too

Frigidaire dishwasher - upper spray arm trouble?

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.

Hi mike_poulton,

I'm Harvey the master Plumber.

Your question is: You have one of the above models and it has been a fantastic dishwasher but now it seems not to take in water even on rinse and the timer does not decrease.
Any ideas please the model is 6 years old and if too expensive to repaire it will sadly have to go.

This may sound stupid but first make sure no one turned the water off to the d/w. If OK then you likely have a clogged or failed solanoid valve. The d/w must be removed for replacement. I don't recomend this for the average homeowner. You might consider utilizing our Repair Directory to find a repairman.

Feel free contact me again!

The sound is almost always caused by a worn docking cone “O” ring on the main conduit. When the docking cone “O” ring wears, the mid level spray arm conduit is no longer constrained and it can vibrate against the docking cone, making the “growling” or vibrating sound. Use a plastic wire tie to quickly verify if the growling noise is coming from a worn “O” ring. Snug the mid
spray arm coundit against the upper rack with the plastic wire tie. Run the dishwasher. If the noise goes away, you have verified the presence of a worn “O” ring. Remove the wire tie when the test is completed.
The recommended repair for this problem is to replace the WD12X10059 (titanium) or WD12X10121 (grey) docking cone. These parts supercede to the full main conduit. It is not necessary to replace the full main conduit for this problem. Remove the docking cones from both the existing and new main conduits. Install the docking cone removed from the new
main conduit on the existing conduit still installed in the dishwasher.
