DISHWASHER FILLING UP WIYH WATER WHEN NOT IN USE


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.

1
Allow the current cycle to complete. Draining will occur at the end of the cycle.

Close and latch the door. The dishwasher will not drain if the door is not properly secured.
Press the "Cancel/Drain" button on the dishwasher to start a two-minute drain cycle.
4
Remove the knockout plug in the disposer outlet of the garbage disposal if the dishwasher drains into the disposal. Turn off the water supply and remove the drain hose from the disposal. Place the tip of a screwdriver on the plug and tap it lightly with a hammer to remove it. Replace the drain hose and turn the water supply on.
Clogged Drain
5
Run the garbage disposal to empty it and clear the drain if the dishwasher drains into the disposal.
6
Remove the cover on the air gap on the sink or countertop. Turn the plastic cap counterclockwise to remove it. Remove soil from the inside of the air gap. Replace the plastic cap and cover.

Issues With the Drain Hose
8
Check to see if there is a loop in the drain hose. The loop cannot be more than 20 inches above the floor. Disconnect the hose and loop it just above the floor. Reconnect the drain hose.
9
Remove kinks in the drain hose. Always use the new drain hose included with the dishwasher. Do not reuse old hoses.
10
Check the length of the drain hose. The hose should be less than 12 feet long. Replace with a shorter hose, if needed.

I replaced a disposal and now when I run the washer cycle the used water shoots out the drain that is on top of the sink. It didn't shoot out that drain while the old disposal was working and the dishes were getting just as clean. Should I be worried?


The new disposer has a plug inside the dishwasher nipple that you must knock out. The dishwasher hose nipple is plugged so water won't leak out if you don't have a dishwasher connected. You must take a flathead screwdrivers and knock out the plug inside the nipple with a hammer or something. Make sure you don't leave the plug inside! The air gap is designed to prevent water from siphoning back into the dishwasher. With the disposal's drain connection blocked, the water exits through the air gap!

I would like to know where is the plug for dihwasherdrain plug located ot he garbage disposal


It's not guaranteed that your particular model will have a dishwasher drain nipple, but it does, it'll be on the side, near the top of the machine. If the disposer is new you must knock out the plug inside the nipple before connecting a dishwasher. If the disposer doesn't have a nipple, you can get a piece of pipe to fit to the non-disposer side of the sink where you can connect the dishwasher drain hose.

It sounds like you have connected your dishwasher to a garbage disposal.

  1. The 2 hoses provided with your dishwasher connect together.
  2. You run the drain hose through a hole in the bottom/back of your cabinet, then up to the top of the cabinet, then connect it to the drain on the garbage disposal. (The reason that you run your drain up to the top of the cabinet is: This is called an air gap, and helps keep a little water in the drain line, which will prevent sewer gases from entering your dishwasher.)
  3. Be sure to knock the plug out of the drain of the garbage disposal. A garbage disposal is designed to work with or without a dishwasher. The plug is in the center of the drain. The best way to knock this plug out is to pull the garbage disposal, and with a flat screwdriver, knock the plug out.
  4. Then remove the plug from the disposal. Reinstall the disposal.
  5. Install the drain hose. The drain hose will connect right up to the disposal using the clamp provided with the dishwasher.
This should help you. If not please attach more info.
