How To Fix Bosch Dishwasher Not Spraying Water

Facing Bosch Dishwasher Not Spraying Water issue? No need to worry. I also faced the same when I got one and used it for some time.

Initially, it worked perfectly and nothing unusual happened but as the time passed, I started facing several problems.

Bosch dishwashers are well-known for their high quality and ease of use, but not everyone realizes that Bosch dishwashers are also easy to fix!

As long as you have the right tools and basic DIY skills, you can save yourself from hiring expensive contractors or replacing your dishwasher altogether.

In this article, we’ll walk you through what you need to do to fix your Bosch dishwasher if it stops spraying water through the jets in the bottom of the tub.

Check for clogs

If your Bosch dishwasher is not spraying water, it’s possible that a clog has formed in one of its many hoses.

To check for clogs, you’ll need to remove all of these hoses from their connections and clean them off with hot water.

If you do find a clog, reach inside and break it up. The main hose should be easy to clean; just make sure to watch out for sharp pieces of food or other particles inside.

When you put everything back together, use new O-rings where appropriate (especially on connectors) to ensure that no leaks occur in the future.

Remove drain hose

It’s important to ensure that there is nothing blocking your drain hose. You can do so by clearing any debris or solid objects in it.

If you find that there are no issues with your drain hose, remove it and clean out all of its surrounding areas to ensure it is clear of any debris.

Then, reinstall it back into place. If there are still issues with water not being sprayed, check your water supply to ensure there isn’t an issue with either an area of the low pressure or an issue with a tripped pressure switch causing no water flow at all.

Check if the spray arm is broken

This is one of the most common causes of dishwashers not spraying water. The spray arm is a stainless steel piece with little plastic nozzles at its end.

If it’s cracked or broken, you need to replace it. Otherwise, move on to our next step.

Ensure there’s water flowing into your dishwasher: Check under your sink to ensure there isn’t a shutoff valve turned off, and be sure your hot water supply is functional.

Try removing any kinked hoses or loose connections.

Replace pump assembly

If you are experiencing a clogged sprayer in your Bosch dishwasher, it’s probably time to replace your pump assembly.

The pump assembly is responsible for pushing water from your utility sink into your dishwasher, and then spraying it onto dishes as they rotate through a series of rotating sprayers.


When these sprayers fail to provide adequate coverage, you may want to replace them with new ones—but before doing so, check and make sure that your pump assembly isn’t causing any problems first.

Turn off both power sources (the breaker switch and hot water) connected to your dishwasher and pop open its front panel to check if your pump is working correctly.

Install new pump assembly

If your dishwasher isn’t spraying water, your pump assembly may need to be replaced. Since no water will come out of your dishwasher, there are several ways you can troubleshoot it.

The easiest is to check that you have power going to your dishwasher. After that turn on a sink sprayer (or a hose).

If water comes out, but not from your dishwasher, it’s most likely that you have an issue with your pump assembly.

The first step in replacing it is removing the lower wash arm by pulling down it and pushing it forward.

If your dishwasher isn’t spraying water, there are a few possible fixes. First, check to make sure that your faucet is turned on at both ends. Also, check that it’s not clogged up with lime buildup.

Second, check to make sure you don’t have an air gap in place; if you do, try to remove it or just run a cycle without it in place.

If none of these steps works for you and your dishwasher still won’t spray water, then it may be time to contact a plumber.

You can also contact Bosch support if you do not get any clue about solving the issue. They are experts and can guide you better in this regard.
