Reasons for Bosch Dishwasher Not Draining

If your Bosch Dishwasher is not draining, it can be very frustrating. Fortunately, there are a few common causes and solutions for this problem that you can try to get your dishwasher back up and running. Here are some of the most common reasons why a Bosch Dishwasher isn’t draining and what you can do about it.

The first thing to check if your dishwasher isn’t draining properly is the filter inside the appliance. It’s located at the bottom of the machine and should be cleaned regularly in order to prevent clogs, which can lead to drainage issues.

A faulty drain pump will affect how clean your dishes get as well as potentially leading to water damage in your home if it overflows. Knowing how to spot a failed drain pump and how to repair or replace it can help save you time and money in the long run.

The first step is to check for any blockages in the drainage system that could be causing issues with the dishwasher draining properly.

The issue can range from a minor blockage to a much more serious problem that requires professional assistance. Fortunately, some basic troubleshooting steps can help you identify and address the source of the clog.

If your Bosch dishwasher isn’t draining, it could be the result of a clogged drain line. To begin troubleshooting, check the filter located in the bottom of the machine for any debris or food particles that may be causing a blockage.

Obstructed Filter of your Bosch Dishwasher:


Having a dishwasher that does not drain is one of the most common problems that a homeowner will face. If you own a Bosch dishwasher and it’s not draining, it may be due to an obstructed filter. The filters on Bosch dishwashers are designed to catch any food particles and other debris that is washed off the dishes. Over time, these particles can build up inside the filter and cause it to become blocked or clogged, preventing water from draining properly. Fortunately, this problem is relatively easy to fix with just a few simple steps.

To start, turn off the power supply to your dishwasher before attempting any repairs. Once this is done, open up the lower panel inside the machine and locate the filter assembly.

Clogged Dishwasher Air Gap:

A Bosch dishwasher not draining properly can be a headache for any homeowner. Clogged air gaps are one of the common causes behind dishwasher drainage issues, and they can cause water to back up into the sink or even flood your kitchen. Fortunately, fixing a clogged air gap on a Bosch dishwasher is relatively simple and doesn’t require much technical know-how. All you need is an Allen wrench, some pliers, and a few minutes of your time.

To begin, locate the air gap–it should be located near the top of your sink’s countertop or underneath it. Once you have found it, use an Allen wrench to unscrew its cap and lift it off. Then take some pliers and remove any debris that may be blocking the air gap opening.
