LDF 7811 bottom sprayer not working - suspect diverter valve

\015 I have a LDF7811 approx 4yrs old. The bottom sprayer does not work, in fact it will not move even though the upper two sprayers do spin and spray. I have tested this in several settings - half load bottom, rinse cycles full cycles and let them run such that there is ample time for the sprayers to alternate though it never happens. I removed the filter housing and internal molding to expose the diverter valve, my hunch is that it must be that the valve is defective, or the control for it is no longer working. If a sensor is used as part of the feedback loop it certainly could be that. I didn't notice any debris or abnormal build up under the filter. Any advice is appreciated. If the diverter is defective what are my options for getting a replacement part and is there a service manual available that outlines common disassembly and assembly repairs? Thanks SJ\015

Answers :

The vario motor that attaches to the check valve can be accessed by pulling the unit and turning the entire DW over on its top.

This thing is not light and please be careful.

Remove the entire (black) base support assembly so you can see all the motors, etc.

Here is an example source for the vario motor

G.E. GSD5130 When the dishwasher is pumping out the water a small amount comes in the rotating sprayer head. At the end of the cycle the dishwasher still has water in the bottom. The amount of water varies from just a little to over an inch. I replaced the spring loaded check valve a couple of months earlier and everything worked fine until now. What should I check? Thankyou.


Mike, I just ran into the same problem. I found a second check valve located in the outlet hose of the ELECTRIC drain motor. This motor is located at the right rear underside of d/w and is used only for backflush of the filter. When the unit goes th ... GE GSD5130 Dishwasher

Kenmore dishwasher type 573-D, model 665.16034402. Items on top rack don't get washed. Items on bottom rack are washed fine. Appears top sprayer and maybe middle sprayer aren't getting water. At rear of washer, top rubber flapper valve (which feeds middle sprayer when top rack is in raised position) is stuck open, bottom flapper valve looks OK. We use top rack in raised position so this doesn't seem to be the problem.

Previous wash cycle worked perfectly. Next morning , dished not washed. Water pressure is insufficient to spray. Checked sprayers and clean. Removed bottom sprayer arm and tested. Water flows barely. Water fills but pressure insufficient to spray. Actually 'bursts' slightly on shutoff. All other functions work perfectly.

We have a built in GE dishwasher. It has worked fine for about 4 years but now the glasses in the top rack will not come clean. I have cleaned all the holes where the water comes out but I think the sprayer that is beneath the top rack (the one that is attached to the bottom of the top rack) is not rotating. We had someone out to take a look at it and they said it was fine. It isn't fine as it is not cleaning the dishes. Is there a reason that the bottom sprayer is not turning?

It appears that water is not running through the dishwasher or that the sprayers are not working correctly. There doesn't appear to be a clog. However, I did find a round rubber "washer" (I think that is what they are called) laying in the bottom of the dishwasher - where does this part go. It was working fine until this wash. The heating element works fine but like I said it appears that something may be wrong with the spray tower. Please advise Model number of Hotpoint: HDA3420Z01BB T

Miele dw flashes 5 times, water is draining. Suspect filter/valve housing at end of water inlet line. Their is a wire running to this valv so I imagine whatever solenoid that tells the valve to open and let water in is not working. Am I close? I cleaned inlet filter.


Which light is flashing? if the intake drain light is blinking and you dont hear the drain pump, it means water is not coming in. if the drain pump is running all the time, it means water has leaked into the bottom pan. behind the plastic toe ki ...

SHX46B I have a 4 year old Dishwasher that filled up with clean water on it's own and leaked on the floor. There appears to ba a float switch switch on the very bottom of the unit that runs the pump if this happens. It won't stop until I remove the water caught in the plastic base on the very bottom of the unit. Drain is clear and this machine has worked fine until now. I'm thinking it may be a bad or leaky fill valve but how can I check?

Hello, I have a Kitchen Aid dishwasher, model KUDS30IVWH3. The dishes have not been getting as clean lately, the bottom is decent but the top rack is not getting very clean. Also, when I open the door after the cycle is done, there's a bunch of detergent at the bottom of the door and on the floor of the dishwasher, like it isn't getting sprayed all over or something. Don't know if I have to check the water intake valve or if maybe the sprayers could be partially clogged.

Dishwasher stopped cleaning but appears to run through cycles. Possibly water starved. The bottom "sprayer has some water coming through the holes but is not spinning, (although spins freely by hand). The top and middle "sprayers" definately aren't functioning. Stopped working suddenly, (not a gradual change).

Whirlpool Quiet Wash Plus dishwasher Model DU920PFGZ3. Worked fine until I replaced the insinkerator and forgot to punch the drain plug leaving water standing on the bottom of the machine. I punched the drain opening, and pushed the cancel/drain cycle button. It drained fine but since no water comes from the spray arms. I have removed the arm all the way down..NOTHING!! Some research indicated it could be the water inlet valve. When the buttons are pushed, it cycles but no spray or water.
