The dishwasher does not drain, i just replace my garbage disposal and now the dishwasher does not drain, i did reconnect the dishwasher drain hose to the garbage disposal

Is disposal newly installed? If so, there’s a knock out plug in inlet to disposal. If that’s not it, disposal or drain is obstructed

If the garbage disposal is clogged, the water from the dishwasher cannot drain. Most of the time the dishwasher drain hose is connected into the garbage disposal. Check to be sure water flows freely into the garbage disposal. You should hear it running into the bottom of the disposal when the dishwasher drains. The line connects to the garbage disposal at the top of the disposal with a hose clamp. If you undo it take the hose off and make sure the punch out inside the disposal tube is all the way punched out and there are no restrictions in their..ie stuck food particles or something else. Unplug the disposal when working on it. Just to be safe.
Hope this helps.

see this causes and proceed according. God bless you
Belt, Water Pump Although few dishwashers have a water pump belt, if the dishwasher won't drain there might be a worn or broken water pump belt. After removing the lower kick panel the motor can be seen in the front, the water pump belt is on the bottom of the motor.

Drain Pump If the dishwasher won't drain, the drain pump might be defective. Test the pump motor with an Ohm meter. Drain pumps are not repairable, if it's defective it will need to be replaced.

Drain Impeller The drain impeller is attached to the pump and pushes the water out of the dishwasher, through the drain tube and into the garbage disposer or drain line. If the dishwasher won't drain, the drain impeller might be broken or worn out. Replace both the impeller and seal at the same time.

Drain Solenoid Kit If the dishwasher won't drain, the drain solenoid kit might need to be replaced. The drain solenoid is an actuator that opens a flap to allow the water to drain.
Drain Valve The drain valve can get clogged with debris and should be cleaned out if the dishwasher won't drain. If it seems clear of debris but won't actuate, it will need to be replaced. The drain valve is not repairable Pump and Motor Assembly If the dishwasher won't drain, the pump and motor assembly might be defective. If the motor runs during the drain cycle, check for a blockage in the drain line. If the motor won't run during the drain cycle or if it just hums when it should be running, the pump and motor assembly might need to be replaced.

Clogged or Improperly Installed Garbage Disposer If the dishwasher won't drain and the garbage disposer was installed recently, the installer might have forgotten to knock out the drain plug from this disposer. All garbage disposers are sold with a solid plug in the drain tube for situations where a dishwasher isn't connected. However, if the dishwasher is connected, the plug will need to be removed. If the disposer wasn't replaced recently, remove the dishwasher drain hose from the disposer and clean out both the fitting on the disposer and the end of the drain hose. These are the most common places to find an obstruction if the dishwasher won't drain.

Check Valve If the dishwasher won't drain the check valve might be stuck closed. The check valve is a small plastic device which prevents water from returning to the dishwasher after it has drained. If the valve gets stuck closed, it will prevent the water from draining. The check valve is the device that the drain hose is attached to on the dishwasher.

Check Ball If the dishwasher won't drain the check ball might be stuck. The check ball is a small plastic ball in the check valve which prevents water from returning to the dishwasher after it has drained. If the ball gets stuck, it will prevent the water from draining also. The check valve is the device that the drain hose is attached to on the dishwasher.

1
Allow the current cycle to complete. Draining will occur at the end of the cycle.
2
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.
7
Check the sink. Dishwashers connected to a sink will not drain if the sink drain is clogged. Unclog the sink. Contact a plumber, if needed.
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.

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!

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.

It sounds like you've done everything fine. I would disconnect the dishwasher drain line from the disposal, have a bucket ready and see if it will drain. It's possible that there is a plug or something else left in the disposal opening that is blocking the water. If the dishwasher won't drain with the hose off of the disposal, there is a problem with the dishwasher that has nothing to do with your disposal installation. Hope this helps and good luck!

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.

Hi. I just had the same trouble. Your garbage disposal comment there gave me an idea. The drain hose from your dishwasher likely goes to the garbage disposal and then out the drain. My hose had a little blockage at the joint where the hose goes into the disposal. I was able to clear it just by giving it a wiggle....all is well now.

Good luck.

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.
