Bosch Dishwasher Error Code E24 – Causes and Fixes

To find the underlying issue, run through the most common causes and fixes below.

Drain Hose Blockage

A blockage in the drain hose caused by excess food waste can prevent water from draining correctly.

How to fix – Check the Drain Hose

Start by removing the hose from the dishwasher and inspecting it for any kinks or bends that may be obstructing the water flow. 

If you find a blockage, clear it out and try rerunning the dishwasher to see if the E24 error code disappears.

Drain Pump Fault

A faulty drain pump can also lead to this error code, as the dishwasher cannot drain water properly. This may occur if the valve is malfunctioning or not closed completely.

How to fix – Find the Drain Pump and Clean Any Debris

To solve the issue, you’ll need to gain access to the drain pump and clear out any debris that’s clogged. If it’s not clogged but instead looks damaged or broken, you’ll need to source and install a replacement. 

Blocked Filter

The dishwasher filter can become clogged with food particles, soap scum, and other debris, obstructing water flow and triggering the E24 error. This may occur due to a broken pump or a lack of maintenance.

How to fix – Clean the Filter

First, find the filter assembly – it’s usually quite easy to access on the floor of the dishwasher. Turn it counterclockwise and raise it straight to remove it. Using a brush, soap, and warm water, thoroughly clean the filter. 

Once you’ve cleaned the filter, put it back in place and try rerunning the dishwasher.

If the filter has any sign of damage, this could be the problem, and you need to install a new one.

Low Water Pressure

Low water pressure or insufficient water supply can cause the dishwasher to struggle to wash dishes and trigger the E24 error code.

How to fix – Check the Waste Water Pump

If the drain hose and filter are clear, the problem may lie with the wastewater pump. 

To check the pump, you’ll need to remove the dishwasher from its mounting and locate the pump at the bottom of the unit. 

Then, remove any debris you find and try rerunning the dishwasher.

The Knockout Plug Hasn’t Been Removed

NB. This is only relevant if your dishwasher is new or you’ve recently moved.

The knockout plug is a small piece of plastic found within the dishwasher to stop water from getting inside during shipping. 

This plug is usually located where the dishwasher drain hose connects, but if it’s not removed during installation, it can cause your Bosch dishwasher to display error code E24. 

How to fix – Locate the Knockout Plug and Take It Out

You need a screwdriver and a set of needle nose pliers for this one. 

To remove the plug from the dishwasher, gently pry it out with the screwdriver. Lay the screwdriver tip onto the knockout plug and lightly hit it a few times. The extra water will drain after the plug is discarded.

Electrical Fault

Like any other electronic device, Bosch dishwashers can also experience software glitches or bugs, causing the E24 error to appear. 

How to fix – Perform a Hard Reset

The most reliable technique to fix this error code is to do a hard reset.

Switch off the dishwasher and unplug it or turn the mains power off. Then, reconnect the washer after waiting two to three minutes and see if it’s fixed the error.

The Pump Cover is Loose

The drain pump is protected by a plastic cover called the pump cover. If the pump cover is loose, it can cause a leak and trigger the E24 error code.

How to fix – Tighten the Pump Cover

The drain pump cover conceals the drain impeller and pump, but if it is too loose, the pump may flood and cease to function properly. 

Open the dishwasher and pull the lower rack out. Unlock and lift out the drain filter assembly to remove it. You should then be able to see the locking tab that holds the drain pump cover in place underneath this in the sump.

Check for any signs of damage, and source/fit a replacement if required. 

Otherwise, you can re-seal the pump cover by pushing the dislodged impeller cover back into position.

If you’ve tried everything listed, but the error persists, it’s best to contact an appliance technician who will be able to diagnose and fix the machine. 

If your dishwasher is still under warranty, contact your supplier or Bosch first since the fix might be covered.

How to Prevent Bosch Dishwasher Error Code E24

To avoid the frustration of dealing with a clogged dishwasher, it’s essential to practice good preventative maintenance. 

Here are four of my personal tips that can help you keep your dishwasher running smoothly.

1. Clean your dishwasher regularly: Make sure you clean your dishwasher regularly, preferably with a specialist dishwashing cleaner once or twice a month. Remove any debris from the dishwasher’s filter, spray arms, and interior.

2. Use the suitable detergent: Make sure you’re using a high-quality detergent specifically designed for dishwashers. 

3. Run hot water before starting your dishwasher: If you have a hot water feed, running hot tap for a few seconds before starting your dishwasher can help ensure that the water entering the dishwasher is hot enough to dissolve the detergent and adequately clean your dishes.

4. Load your dishwasher correctly: Make sure that dishes and utensils are appropriately placed in the dishwasher so they don’t block or damage the spray arms or the dishwasher’s drain. 

These preventative maintenance tips can significantly reduce the likelihood of encountering an error code, saving you the headache of troubleshooting and repairs and prolonging the lifespan of your dishwasher.


How do you force a Bosch dishwasher to drain?

Press and hold the Start, Drain, or Cancel button on your dishwasher for three seconds to start the drain cycle. If the drain hose is disconnected, place it in a large bucket.

Does my Bosch dishwasher have a drain button?

Look at the control panel on your dishwasher. Most dishwashers have a “Cancel” or “Drain” function. It should be noted on the control that, occasionally, this will result in the simultaneous pressing of two buttons.

How do you manually drain the bottom of a Bosch dishwasher?

Line the floor of the dishwasher with paper towels or newspaper, then use a measuring cup (preferably plastic) or similar to scoop the water into the sink. When it’s too shallow to scoop, clean what’s left with a towel.

How does my Bosch dishwasher know when to drain?

Your dishwasher has a float that indicates how much water is in the machine and when to drain. Food particles, utensils, and other things that become stuck in your dishwasher’s components might cause the float to become stuck and the dishwasher to become confused. 

Which cycle drains a Bosch dishwasher?

In normal operation, all of the water is drained following the primary wash. Depending on the cycle, the main wash might take anywhere from 20 to 90 minutes.

Why doesn’t my Bosch dishwasher drain at the end of the cycle?

Food particles clogging the water pump or filter are the most frequent cause of a dishwasher not draining. This is why it’s crucial to maintain your dishwasher and clean it thoroughly on a regular basis.

Why is my Bosch dishwasher beeping and won’t drain?

When an error occurs, Bosch dishwashers are designed to beep and get your attention.
