Dishwasher Not Draining

Is your dishwasher not draining water after the cycle is completed? While there could be one of a number of different reasons causing the water to backup, you must take it one step at a time to identify the problem. Here we’ll take a look at some of the most common causes for a dishwasher not to drain. We recommend going through the causes outlined below to determine what’s wrong with your unit.


Check The Sink

If your kitchen sink in your home are backed up as well, there’s a good chance the problem could be related the main drain line. In this instance, a backed up septic tank could be preventing the water from draining down the sinks and from the dishwasher. Call a septic tank service immediately to get the problem fixed before it causes further damage to your yard or home.

Drain Hose

The most common reason why dishwashers don’t drain is usually because the drain hose is clogged. As the name suggests, a drain hose is a line that’s used to dispose of the dirty water in a dishwasher. If food particles, soap scum or some other debris gets stuck inside of it, a clog will develop, preventing the water from draining as it should. Unfortunately, checking the drain hose line is a fairly complicated procedure that involves the partial removal of your dishwasher.

Drain Pump

Dishwashers work by using a drain pump to force the used water into the drain hose. If this pump becomes broken, there’s simply no way for the water to make its way into the drain hose, therefore it backs up in your dishwasher. You can do a quick inspection of the pump’s exterior to ensure there’s no debris or food particles blocking the water dispersion system. If the pump is physically damaged or broken, you may need to replace it before it pumps as it should.

Other Causes

While the 3 causes outlined above are usually the most common reasons why dishwashers don’t drain properly, the fact is that there could be a number of other reasons. Dishwashers contain a lot of components, which can break and deteriorate over time. You have to remember that water and food particles are constantly being passed through these machines. Because of this, it’s only inevitable that parts will break over time. If your dishwasher isn’t draining the water as it should, check the reasons outlined above, and then call a professional repairman to come out and inspect it.
