Just connected a new garbage disposal up, and dishwasher won't drain anymore

Drain hose clogged or Not ran in the proper draining position, under the sink where the hose ties into the drain system or garbage disposal, the hose should be higher than the connection point, I have fixed this by tie strapping hose to the bottom of the counter or sink, hope that helps ?

If you hooked up the drain to the disposal directly there is no vent in the line. Use the air vent on the sink to connect the dishwasher drain hose. If there is no air vent, then you'll have to install one in the sink.

Your dishwasher drains into the garbage disposal. It you tried to use a plunger to clear your clogged sink or run the disposal with to much junk in it you may have force debris into the dishwasher drain hose. With both the dishwasher and garbage disposal disconnect from power disconnect the dishwasher drain hose from the garbage disposal. This is usually about a one inch black hose. Clear out any debris in the hose and inlet nipple on the garbage disposal. If debris is compacted far down the hose it will need to be disconnected from the dishwasher end and remove to clear the blockage.

Good luck!

Make sure the drain hose connected to your garbage disposal is connected well. Also, the hose should loop up near the sink (counter top) before it loops back down about 3 inches below the drain connection on the garbage disposal (or sink drain pipe if you don't have a disposal). This effectively makes a drain trap to avoid any smell from the dishwasher.

Also make sure the door is closed properly and there is no packaging material on the door.

The pump is a motor which runs in one direction to spray water in the dishwasher to clean and the opposite direction to drain the water. The problem could be from a clog or kink in the drain hose. Several years ago the drain line would connect to the sink garbage disposal. If the garbage disposal is not draining or the dishwasher connection to the garbage disposal is restricted or clogged the dishwasher will not drain. Under the sink, look at the garbage disposal to see if a rubber hose is connected at the side of the disposal unit. If a hose is connected to the side of the disposal, remove the hose clamp and check for any restrictions from garbage in the inlet or hose. You can use a screwdriver to clean the fitting to the garbage disposal and a wire hanger to free any restrictions in the hose. If the dishwasher does not connect to the garbage disposal it should connect to the sink trap. This is more common with new dishwashers because they have built-in disposals. Disconnect the drain hose from the sink trap and the dishwasher and look for a clog at the sink connection. The dishwasher inlet should have an angled piece of plastic or metal facing downward to prevent the waste from the dishwasher from spraying up into the sink. Do not get to aggressive with the cleaning in order to prevent breaking the angled piece of plastic or metal. Look for any kinks in the hose and try to run water through the hose, but do not use the sink which you removed the drain line from or it could leak under the cabinet. If you see a bad kink replace the hose with a new one. I hope this works and you find the problem without a great deal of time or trouble.

The leak in an air gap is usually caused by a clogged sink discharge line. Most of the time this is connected to the garbage disposal and there is food particulate in the drain hole where the dishwasher drain from the air gap to the garbage disposal connects.

Pull the sink connection hose off and clean the hole thoroughly. You can try testing the dishwasher/ air gap by placing the disconnected hose into a bucket during the pump out period. It should not leak. After this test...reconnect the hose to the sink connection.

If it is NOT connected to the garbage disposal then remove the hose and clean out the hole where the connection is made. This is a common problem and easily resolved by the user.

There is a breakaway stub in the garbage disposal's dishwasher hose port, it needs to be removed before connecting the dishwasher drain hose when installing the disposal.
Disconnect the dishwasher drain hose at the disposal, get a screwdriver and, insert in the disposal's dishwasher drain port and tap on it with hammer until it breaks off. Then remove that stub from the sink side.

cycle the dishwasher, and after it fills with water, dump 6 cups of bleach in there and let it contunue. just before it starts to drain, stop it and let it sit for an hour. restart dishwasher and let it cycle thru.

the obstruction they talk about in the disposer, its where the connection for the d/w drain is made, there is a "knockout" plug within the drain line connector( in case you dont have a d/w) that would need to be removed before the d/w will drain. can be popped out with a good smack with a screw driver, the plastic knockout will land within the disposer. disconnect power and remove the plug, it will not break up and wash away

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.
