Does Your Bosch Dishwasher Drain Pump Retain Water?

When draining water from your Bosch dishwasher after cleaning, you may realise that it is taking longer than usual to drain. Don’t make light of it. The most probable cause of this is a blocked drain pump. The blockage could be food particles or debris trapped in the drain pump. If unsure, you can get a Bosch dishwasher repair expert to get rid of the debris or particles. In most instances, the problem can be easily solved by giving the filter a good clean.

Below are some key considerations when cleaning the drain pump:

Shut down the power

First off, you need to turn off the power. This is the easiest part, and hence you should not forget it. Once done, you can then open your dishwasher and remove the lower rack.

Wash the filter tube

Next to the wash arm, you will find the filter tube top. Reach out to it if you can. It is usually made of stainless steel. This top is usually rotatable. Move it gently to the anticlockwise direction at an angle of 90°. This way, you are now able to reach the filter tube. Wash the tube thoroughly with clean water until you are sure there is no more debris left.

Manually dry the sump

When done, you can now move to another area that could be holding water called the sump. You will find the sump at the bottom of the Bosch dishwasher. It is white and secured by clips. Looking at it carefully, you may see some water here. Eliminate as much as humanly possible, until you cannot scoop it anymore. At this point, get an absorbent clothing and remove the rest of the remaining water till the sump is dry.

Clean the impeller blades

The next place to look for debris would be within the impeller blades. To reach them, you may need a screwdriver in hand. On the left side of the sump, you will find the draining pump. You should remove the retaining screw using the screwdriver. When successfully opened, you can then see the impeller blades. You will find lots of debris and particles being held at this part. Remove all these particles and make sure the impeller blades are completely clean. Before you close it back by returning the screws, you should make sure you have gotten rid of all debris.

This bit of unrevealing the impeller blades may sound a bit challenging mainly because you need a tool to have it done. However, this is a straightforward task that you can comfortably handle at the comfort of your home.
