I am assuming you cleared all the old water out and the drain is now clear. Dig out your manual and do a "factory reset" if you can't find it in the manual should be able to find it on line. Sort of starting over type of thing.

SOURCE: How to knock out garbage disposal plug

Turn off the power source to the garbage disposal. Take the drain hose from the dishwasher off the connector going to the disposal (if connected). Insert a flat blade screwdriver in the drain hose fitting and tap a few times with a hammer. The plastic plug will pop off inside the garbage disposal. Reach inside from the top of the disposal to retrieve the plastic plug. Sometimes you have to use a little force to tap the plug out. Hope this helps you.

SOURCE: dishwasher not working

Nothing by the sound of it. The humming may mean the main pump is stuck. If you are able, remove the pump & turn the impellor by hand (or screwdriver) just to make sure its free moving. Put it back into machine & see what you get. Could also mean that the capacitor on the main pump (if it is a capacitor start motor) has failed.

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.

Dishwasher not emptying out water

If you recently replaced your garbage disposal make sure the "knock out" plug was punched out to allow drain water into the disposal. The guy who replaced my disposal forgot to do it and my dishwasher would not empty. It's an easy fix. Just remove the drain hose from the dishwasher that attachs to your garbage disposal. Look inside with a flashlight and you will see if it is still there.
If it is, take a hammer and screw driver or punch and knock it out. TURN OFF POWER to your disposal and you can retrieve the "knock out" plug (piece of plastic about the size of a dime). Replace your drain hose to the disposal and try your dishwasher again. Worked for me! Good luck.

We just replaced our garbage disposal and now the dishwasher won't drain. I order a drain pump and it still won't drain.

Make sure that the air clear on top of the sink is clean and clear all the way through. Sometimes in replacement silt and other garbage clog this up and keep it allowing water to drain properly.

I installed a new food grinder under the sink. I also replaced the dried out rubber hoses that connect the food grinder to the dishwasher. But no matter what program I use, the dishwasher refuses to drain...

Check to make sure you removed the plug inside the garbage disposal inlet where the dishwasher drain hose connects. This is a common mistake installers make when installing a new garbage disposal. Make sure the power the the disposal is secured and remove the drain hose. Place your finger inside the inlet on the side of the disposal. The opening should be clear. If not, you simply need to insert a flat blade scewdriver through the inlet connection and tap out the plug with a hammer. The plug will pop out inside the disposal, so you will need to reach inside and retrieve it before attempting to use it. Once the plug is removed, reinstall the drain line and test operate your dishwasher by starting a cycle. Once the dishwasher fills and begins the wash cycle, press the STOP/CANCEL button to initiate a drain cycle. Your dishwasher should drain with no problems. If you have any questions, please post back and let me know. I hope this helps you.

After I installed my Badger 5 my dishwasher would not drain. Is there a plug in the dishwasher port on the side of the disposal and how do I remove it?

There is often a plug in the ISE as many people use them without have a dishwasher connected to them. Quite often it is just a thin plastic membrane that can be knocked out with a screwdriver. There should also be a note to this effect in your installation instructions for the ISE.

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...

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!

How doI hook up to dishwasher - How do I remove the cap?

you're already on the right path of doing what needs to be done. you have to use a long flat screw driver (or anything small and long enough to reach the knock-out) and punch/knock out the drain plug of the garberator. once you knock it out, you'll have to remove the piece that comes out of the plug. it's best to do this with the unit out on a bench or something though. (although I never remove the unit from the sink, but I've been doing it a very long time now)

good luck
