Reasons for a clogged dishwasher

Reasons for a clogged dishwasher

1. Food stuck in the filter basket

The filter basket in the dishwasher is made to catch the residuals of food that come from the dishware. The filter’s purpose is to avoid the residuals from going into the drain and cause a clog. However, if the food limit exceeds, the water will not pass through it and cause a clog.

2. The drain hose is clogged

The water from the dishwasher drain passes via a hose connected with a drainpipe or the garbage disposal under the kitchen sink. When the clog is formed by the residual parts of food and soap, the water will have no way to pass, and ultimately it will come back in the dishwasher. The result is your dishwasher not draining.

3. Garbage disposal

Garbage disposal

If you have a newly installed garbage disposal in your dishwasher, then it can cause clogging. It is a common mistake that people forget to remove the knockout plug when the garbage disposal is installed. If you remove this plug, you will solve your problem.

4. Sewer line damaged

A broken sewer line can cause the clogging of your dishwasher. The fractured sewer pipe of your home can block all of your drains at home, and as a result, your time waste and not able to drain the dishwasher.

5. Other drains are clogged

There is a possibility that your dishwasher has no concern with your clogged drain. There might be another drain clogged more down to the sewer line, which is causing a clog. 

In this case, your drain system cannot drain properly. However, having more clogged drains at home or the water gurgles back to the sink when the dishwasher drains, some serious issue demands your attention.

After the removal of the standing water in your dishwasher, check the drain hose of your dishwasher. The drain hose is responsible for linking the machine with the garbage disposal. The drain hose is most probably located under the sink or behind your dishwasher.

If the drain hose is behind your dishwasher, then you’ll have to drag your dishwasher away from the wall to get easy access.

After locating your drain hose, remove it from the dishwasher. Place a pan down the hose to catch the water from the drain. Remove the hose and start to clear it. Use the de-cloggers to clear your hose properly. If there is no debris in the hose, then there are chances that the clog is inside the dishwasher itself.

Further, you have to apply the same methodology by using a de-clogger to remove the debris clogging in your machine. After the removal of the clog, your dishwasher is ready to use.
