Is Your Dishwasher not Draining Water?

Washing dishes by hand used to be a frequent practice.  Today, most of us rely on a dishwasher to clean our china and silver sparkling.  It is lovely until it doesn’t work.  If your dishwasher won’t drain water, there can be a number of reasons.

Let’s review some of the most common issues why your dishwasher is not draining water.

Reasons why your Dishwasher is not Draining Water

Drain Hose

Depending on the brand and model, your dishwasher will have either a drain hose or an air gap. 

This clog usually happens when the hose attaches to the main household drain or connects to the garbage disposal. 


This is a combination device that is composed of a pump, washer impeller, and drain impeller. 

The pump forces the water out; the impeller forces it through the spray arm, and the drain impeller gets the water to the drain port.

This assembly could be clogged, or parts are not functioning as they should or are just worn.


Again, the pump assembly can be driven by a belt depending on the make and model of your dishwasher

When your dishwasher is not draining water, these wear out or down, and can’t move the pump correctly.  If that happens, the belt should be replaced.


Sometimes the timer is defective and won’t engage in draining the dishwasher.  It could be you need to replace the entire timer assembly or just the motor.


The dishwasher’s motor runs everything, including the ability to drain.  If it is in bad shape, you may need a replacement.

Drain Valve and/or Solenoid

If the timer works well, you must check other aspects of your dishwasher. 

Your machine likely works with a valve that is controlled by a solenoid.  If either one has broken down, you will need replacement parts. 

What to do if your dishwasher is not draining water?

Your dishwasher is a mechanical device, and regular maintenance is one of the best ways to avoid an emergency.  Some of the things you can do are:

  • Clean the filter and trap.
  • Keep spray arm holes clear of any clogs or debris.
  • Check the racks for any loss of the rubber sealant.  When this peels off and leaves raw metal, you can expect rust; the metal and sealant bits can clog a drain.  These racks should be repaired or replaced.
  • Check hose clamps to be sure they are in the right position.
  • Look at the door seal to be sure it is not cracked or allowing leaks.

While some of these repairs may seem easy, if you don’t have the proper tools or access to the replacement parts, you will be spending a lot of extra money and time, not to mention the potential of having your kitchen flooded with water-backed up from a faulty drain.
