Ensure that the drain hose is in satisfactory working order.

The first thing to check if your Kenmore dishwasher is not draining is to check if the drain hose is clogged. Ensure that your Kenmore dishwasher is clear of any food or debris by lifting its front cover. There may be two drain hoses on some Kenmore dishwashers, so you should inspect both of them.

Using a star-shaped clip, the Kenmore hose attaches to the main drain pipe in your sink. In the event that this clamp loosens or falls off, the water will drain out rather than drain into the Kenmore dishwasher. If you have any missing clips, you should replace them with new ones from an auto parts store; they’re cheap and easy to install.

The first thing you should do is inspect the hose that connects the water line to the drain under the sink for kinks. A kink or obstruction in this area can prevent water from draining properly due to pressure.

Ensure the line between your dishwasher and cabinet is not kinked, and look behind/below your dishwasher for sharp bends. Dishwasher drains should be cleaned out of kinks and tested.


The dishwasher drain filter is clogged.

In case of an accumulation of debris in the Kenmore dishwasher filter, it may clog up and prevent water from draining. You can find Kenmore’s owner manual on their website if you don’t know where to locate or how to remove this filter. 

Before returning it to its original position, use a stiff brush to remove any obstructions. After reinstalling the Kenmore dishwasher filter, make sure adequate drainage has been restored.


There is a clog in the dishwasher’s garbage disposal.

Please make sure that if the disposal has been recently installed, you do not forget to remove the plug from the disposal.

Make sure the drain pump is functioning as it should.

Kenmore dishwashers have pumps that maintain water pressure, so they’ll keep pumping. If your Kenmore dishwasher is not draining, there may be an issue with the part that is causing it to not drain.

In either case, the drain pump either isn’t getting power or is defective, which prevents it from draining the water from the system. Make sure the drain pump is running properly by checking its connection with a multimeter.

Ensure that the drain impeller is in good working order by inspecting it and replacing it if necessary. The impeller must be able to spin freely so that it is able to perform its function. It should not be possible for large food bits to slip through the food chopper when it is spinning.


The air gap needs to be cleaned.

The air gap in the Kenmore dishwasher can get clogged and become one of the major causes of the dishwasher not draining and ultimately failing. It is possible for your dishwasher to become backed up and not drain if the air gap becomes blocked. Located next to or behind your faucet, the dishwasher’s air gap can be seen as a small silver cylinder.

The first thing you should do before troubleshooting other possible causes of a Kenmore dishwasher not draining is to check if it is clogged. Make sure the top of the dishwasher is tidy and free of food or debris.

Another possibility for a Kenmore dishwasher not draining is a timer that is not set correctly. Refer to your Kenmore’s owner’s manual for directions on how to adjust the timer settings if you encounter any error codes.

Kenmore dishware is not draining due to the wrong type of detergent.

It is possible that you are using the incorrect detergent if your Kenmore dishwasher is not draining. Depending on the cycle and water temperature, Kenmore recommends different detergents. You should consult Kenmore’s instructions to determine which soap you should use.

If you’ve recently switched from liquid detergent to powder detergent. Then use that new variety instead (check the label to see if it’s appropriate for your cycle).


Kenmore dishware is not draining due to an issue with the dishwasher’s check valve.

Many dishwashers have a check valve on the drain hose that prevents water from flowing backwards into the sump. You may find a check valve inside your upper sump assembly or near your chopper blade.

During drain pump operation, water may flow out of the dishwasher. But will then rush back in after the pump stops if the check valve is damaged.

There is a need to examine the check valve for any damages or debris that might be present in it. When replacing the check valve, make sure that it is clean and free of debris, and if necessary, replace it.
