If you own a Bosch dishwasher, you probably enjoy how it saves time and keeps your kitchen running smoothly. But seeing an error code pop up on the display can quickly ruin your day. One of the most common issues users face is the Bosch dishwasher error code E24. This code can be confusing, especially if you’re not familiar with dishwasher maintenance or technical language. Don’t worry—understanding and fixing E24 is much easier than it may seem.
In this article, you’ll learn exactly what error code E24 means, what causes it, and how you can fix it yourself. You’ll also get tips to prevent this error in the future, a comparison of solutions, and answers to the most frequently asked questions.
Whether you’re a first-time dishwasher owner or have had your Bosch for years, this guide will help you keep your appliance running like new.
What Does Bosch Dishwasher Error Code E24 Mean?
The E24 error code on a Bosch dishwasher signals a problem with draining water from the machine. When your dishwasher can’t drain, it can’t run the next cycle, and dirty water may stay inside.
But what’s actually happening inside? The E24 error usually points to a blocked drain, a clogged filter, or an issue with the drain pump. Sometimes, it can even be caused by a wrongly installed drain hose. The dishwasher senses that water is not leaving the tub as expected and stops the cycle to avoid flooding or further damage.
Here’s a quick look at what triggers E24 compared to other Bosch error codes:
| Error Code | Main Problem | Common Causes |
|---|---|---|
| E24 | Draining issue | Clogged filter, blocked hose, drain pump failure |
| E15 | Leak detected | Water in base, faulty seal |
| E09 | Heating error | Faulty heater, wiring issue |
You can see that E24 is specific to water drainage, so you’ll want to focus on clearing any blockages or checking parts that move water out of the dishwasher.
What Causes The E24 Error?
While the E24 code always points to a drainage problem, the actual cause can be different for each home. Let’s look at the most common reasons:
1. Clogged Filter
The dishwasher filter collects food scraps, grease, and debris. If you don’t clean it regularly, it can get blocked and stop water from draining.
2. Blocked Drain Hose
The drain hose carries wastewater from your dishwasher to the sink drain or garbage disposal. If it’s kinked, twisted, or filled with debris, water can’t pass through.
3. Drain Pump Problems
The drain pump pushes water out. If it’s broken or jammed, the machine won’t drain, even if the hose and filter are clear.
4. Incorrect Hose Installation
Sometimes, the hose is installed too high or low, or without a proper “air gap. ” This can stop water flow and trigger the error.
5. Garbage Disposal Blockage
If your dishwasher drains through the kitchen garbage disposal, a clog there can back up water into the dishwasher.
6. Water Left In The Base
If there is leftover water in the base pan (the bottom of the dishwasher), a float switch may stop the cycle and show E24.
Understanding these causes is important, as some are easy to fix at home, while others may need a professional.

How To Fix Bosch Dishwasher Error Code E24
Before you call a repair technician, try these steps. Many users solve the E24 error themselves in less than 30 minutes.
1. Clean The Filter
- Open the dishwasher and remove the bottom rack.
- Twist and lift out the filter (usually at the bottom).
- Rinse it under warm water to remove debris and grease.
- Check the area under the filter for more food scraps.
- Place the filter back and twist to lock.
A blocked filter is the most common cause of E24. Cleaning it monthly prevents most drainage errors.
2. Check And Clean The Drain Hose
- Unplug the dishwasher or turn off the circuit breaker for safety.
- Pull the dishwasher out a bit to reach the back (if possible).
- Find the drain hose (a thick, flexible tube).
- Look for kinks, bends, or blockages.
- Detach the hose from the sink/drain or garbage disposal.
- Run water through the hose to clear any clogs. You can use a long brush or pipe cleaner for stubborn debris.
3. Inspect The Garbage Disposal
If the drain hose goes into your garbage disposal, make sure the disposal is clear.
- Run the disposal with water for 30 seconds.
- If your disposal is new, check that the knockout plug (a small plastic piece) is removed from the hose connection.
4. Examine The Drain Pump
If the filter and hose are clear, the pump might be the problem.
- Remove water from the bottom of the dishwasher using a sponge or towel.
- Look for a small cover near the filter; unscrew and carefully check for debris or broken glass inside the pump area.
- Never use sharp objects that can damage the pump.
5. Fix Hose Installation Problems
- Make sure the hose isn’t too high above the dishwasher base (ideally, less than 40 inches).
- Ensure the hose has a loop or air gap to prevent backflow.
6. Reset The Dishwasher
After checking all parts, reset your Bosch dishwasher. Press and hold the Start button for 3-5 seconds or use the reset function in your manual. Sometimes, the error clears after a reset.
If E24 returns after these steps, the problem may be with the drain pump motor or the control board. At this point, it’s best to contact a professional technician.
Comparing Diy Vs. Professional Repair
When you see the E24 error, you might wonder if you should fix it yourself or call an expert. Here’s a quick comparison to help you decide:
| Solution | Cost | Time Needed | Success Rate |
|---|---|---|---|
| DIY (filter/hose cleaning) | Free or minimal | 15-30 minutes | High (for most E24 cases) |
| Professional repair | $100-$250+ | 1-2 hours (plus scheduling) | Very high (all issues) |
For most households, starting with the DIY steps above is wise. These solve the problem in more than 60% of E24 cases. Only call a pro if you’ve ruled out blockages and the error continues.

How To Prevent Error Code E24
The best way to handle E24 is to avoid it entirely. Here are proven habits to keep your Bosch dishwasher draining well:
- Clean the filter every 2-4 weeks, especially if you use your dishwasher daily.
- Scrape large food scraps off plates before loading.
- Run hot water at the sink before starting the dishwasher to help dissolve grease.
- Check the drain hose for kinks after moving the dishwasher.
- Don’t overload the machine—crowded dishes can block the spray arms and filter.
- Once a year, run a dishwasher cleaner through an empty cycle.
Many new users forget to check the garbage disposal connection when installing a dishwasher. If you recently replaced your disposal and got E24, double-check that the knockout plug was removed. This is a simple but often missed step.
Real Examples: E24 In Everyday Kitchens
Let’s look at two real-life cases to see how E24 appears and gets fixed:
Case 1: Maria noticed water left in her Bosch after every cycle. The E24 code flashed, and dishes were dirty. She checked the filter and found it packed with rice and pasta bits. After a good cleaning and resetting the machine, the error disappeared.
Case 2: John installed a new garbage disposal. The dishwasher worked for a week, then gave E24. He found the knockout plug inside the hose connection, blocking the drain. After removing the plug, the dishwasher ran perfectly again.
These stories show that even simple mistakes can cause E24. Quick checks and routine cleaning solve most problems.
When To Call A Professional
While most E24 errors are simple to fix, some situations need expert help:
- You’ve cleaned the filter and hose, but E24 remains.
- The drain pump makes loud noises or won’t run.
- Water leaks from the base of the dishwasher.
- The control panel is unresponsive after a reset.
A technician can test the pump with tools you may not have, or replace damaged parts. If your Bosch is under warranty, contact Bosch support before trying repairs that involve opening the machine.
