Bosch Dishwasher Code E24 code means something’s up with the drainage. It’s usually because of a blocked drain hose, dirty filter, or installation mistake. To fix it, just clear the hose, clean the filter, and remove any knockout plugs. 

Easy peasy! You don’t have to worry about having filthy and stinky water flooding your kitchen.

I’ll go into more detail about the fixes in this post, let’s hurry before the water spills out!

Why You Might Be Getting Bosch Dishwasher Code E24

Why You Might Be Getting Bosch Dishwasher Code E24

So, what causes a Bosch dishwasher to not drain? Let’s talk about that in detail. 

Blocked and Kinked Drain Hose

The drain hose is responsible for carrying the water out of the dishwasher. 

If it gets clogged or blocked, water won’t be able to drain properly, triggering the E24 error code. 

This can happen if food particles or debris get stuck in the hose or if it gets bent. 

Dirty Dishwasher Filter

The dishwasher filter catches food particles and prevents them from clogging the drainage system. 

Over time, the filter can become dirty and hinder water flow, leading to drainage problems and the E24 error code. 

‘Knockout’ Plug in New Garbage Disposal

When a new garbage disposal is installed, it’s important to remove the ‘knockout’ plug from the dishwasher connection port. 

A knockout plug is a small blockage used to seal off an opening. 

In dishwasher installations, it is placed on the dishwasher connection port of a garbage disposal unit during manufacturing to prevent water or debris from entering

If this plug is left in, it can block the drainage and trigger the E24 error code. 

Bosch Dishwasher Code E24 Fixes

Now, I’ll walk you through all the fixes you need. Let’s get going.

Avoid E24 Error on On Bosch Dishwasher With These Tips

Avoid E24 Error on On Bosch Dishwasher With These Tips

To keep your Bosch dishwasher running smoothly and avoid the bothersome E24 error, follow these simple and practical tips for maintaining a well-functioning drainage system.

Rinse Stubborn Residue

Before loading heavily soiled dishes, give them a quick rinse to prevent food particles from causing clogs. 

I know that sounds like extra work, but it’s much less than what you have to do when you get the E24 error again.

Keep The Filter Clean

Regularly clean the dishwasher filter to remove trapped food particles. 

A clean filter ensures better water flow and reduces the risk of clogs that lead to the E24 error.

Check The Drain Hose

 Take a peek at the drain hose occasionally to ensure it is free from blockages, kinks, or damage. 

Make sure it is properly connected and doesn’t have any restrictions that could hinder drainage.

Verify The Garbage Disposal Connection

If your dishwasher is connected to a garbage disposal unit, ensure that the connection is secure. 

As I mentioned earlier, remove any knockout plugs that may obstruct water flow.

Load Dishes Smartly and Avoid Overloading

Arrange your dishes and utensils in a way that allows water to flow freely. Avoid blocking important areas, as that could lead to clogs.

Cramming too many items into the dishwasher is even worse than putting dishes in the wrong places – you might have to deal with ruined dishes alongside a clogged drain.

Use dishwasher-safe Detergents 

Opt for detergents specifically designed for dishwashers and follow the recommended dosage. 

Excessive suds can interfere with drainage, so use the right amount.

By following these practical tips, you can clear the E24 and even in some cases the E25 error (another code related to draining). So, two birds with one stone.
