Kudm01TJWH0 dishwasher is EXTREMELY slow draining. Plugging the drain into the disposal builds pressure (10PSI?), but no volume. Any ideas?

Check to see if dishwasher drain is attached to garbage disposer. Running the disposer when the dishwasher drains and it will help keep it clean but if the disposer drain line plugs then the water can drain back into the dishwasher. If it does not connect there then you have a slow kitchen drain and this can be fixed by having a plumber snake it. Often it is plugged with grease that can be cleared with boiling hot water poured down the drain. If this is not the problem then check to see if the dishwasher drain is raised as high as it can go under the sink cabinet. Fasten it up with a strap if needed. This will create a trap to keep the water from flowing back into the dishwasher. Do this regardless of your problem. Lastly If the dishwasher does not drain and it is connected to the disposer then the problem is that the knock out plug was not removed when the disposer was installed. Remove the hose at the disposer and knock it out with a screwdriver. This plug is there so you can install disposer without tying a dishwasher in. Otherwise it would leak there. A slow drain may back up and run into the dishwasher before you see any water appear in the sink. If you raise the dishwasher line to the underside of the counter top you should see water in the sink before it begins to drain into the dishwasher. A slow drain may only show up when you are doing a lot of dishes.

Since the drain pump will pump the water out using the "cancel/drain" button, if it did not work then your problem is likely to be in the drain hose system or the garbage disposal downstream from the drain pump. Check for kinks in clogs in the drain hose. Grease can build up in the portion of the drain hose just before it attaches to the garbage disposal.

Hi,

Here is a tip that I wrote that will help you with your dishwasher not draining problem...

Dishwasher Problems - Water will not drain out

Since the drain pump will pump the water out using the "cancel/drain" button, if it did not work then your problem is likely to be in the drain hose system or the garbage disposal downstream from the drain pump. Check for kinks in clogs in the drain hose. Grease can build up in the portion of the drain hose just before it attaches to the garbage disposal.

The disposal isn't being used much which is causing the slow drain. Turn on disposal for few seconds and this should take care of the problem. During the pump out the pressure is greater than just running water from faucet.

This happened to me. Go to your local Lowes, Home Depot, etc and get some disposal claner. Clean the garbage disposal and see if that helps

It sounds like an issue with the sink drain rather than the dishwasher. Many dishwashers are connected to a double sink, one bay of which contains a garbage disposal. If yours is connected in that configuration, run the disposal to clear any food debris that may still be present while running the HOT water into the disposal.

If you have no disposal or if the dishwasher is connected to the other non-disposal bay, check the sink drain again for proper drainage.

The easiest way to do this is to put a plug in the drain (both sides, one at a time), then fill the sink about half way with luke warm water. Then reach in and pull the plug from each side, watching to see how each side drains, but especially the side with the dishwasher connected. If it's slow draining, focus your efforts on clearing the drain on that particlular side of the sink. Try a plunger first before resorting to other methods to clear the sink. If you plunge the dishwasher side, get underneath the sink and pinch off the discharge line from the dishwasher if possible. A pair of vise grips works well, but don't overtighten them.

Some dishwashers have a soft disposal that can eject enough ground up particles into a sink to cause plugging up over time, especially if the dishwasher empties into the disposal side.

You must have your dishwasher connected directly to the garbage disposal and not through an air gap. What is happening is when you disposal fills with water it is siphoning through the drain hose back to the dishwasher. If you sink has a spare hole on the deck install air gap and run dishwasher drain through air gap first. Otherwise make sure you run Garbage disposal often so that water does not get slowed and build up inside.

check and see if the disposer drain port plug was removed. intake/drain light means slow drain or no drain

Can you access the drain hose without moving the dishwasher out? Is it close to the garbage disposal. You probably have a plugged drain. I would begin by plugging the sink that the garbage disposal is in and filling it full of hot water. Then I would unplug it and turn on the disposal and continue running water in it. This should clean the disposal drain well.

If you can access the dishwasher drain hose, you will need to disconnect it and look for a plug. If you can unplug the dishwasher do this first. It may be hardwired in, but some are not. It will all be behind the adjacent cabinetry. Have towels and a bucket handy. It is a good idea to always run some water through the disposal after running the dishwasher (they usually drain into that sink.)


If you cannot access the drain, I would clean the disposal and check all other household drains for slow drainage before calling a plumber. or your dishwasher repairman.


Good luck to you and thank you for using Fix Ya.
