Dealing with a kitchen appliance breakdown is never fun, but finding an error code flashing on your Bosch dishwasher can be particularly stressful. The E24 error code is one of the most common issues users face. Essentially, it indicates a drainage problem. When your dishwasher cannot drain water effectively, the machine halts operation to prevent potential leaking or water damage. Fortunately, you do not always need to call an expensive technician to solve this problem. In most cases, you can learn how to fix the Bosch dishwasher E24 error code yourself with a bit of patience and a few basic tools.
Understanding the Bosch Dishwasher E24 Error Code
Before diving into the repairs, it helps to understand what is triggering the error.
The Bosch E24 error usually signals that there is a restriction in the drainage system.
This could be due to a clogged filter, debris stuck in the drain pump impeller, a kinked drain hose, or occasionally, a software glitch that requires a reset.
The dishwasher’s sensors detect that water is not moving out of the unit fast enough, so it trips the E24 code as a safety measure to protect the internal components.
Immediate Steps to Try Before Disassembling
Before you start taking parts apart, try the simplest fix first: a hard reset.
Sometimes, the computer just needs a reboot.
Simply turn off the dishwasher, unplug it from the power source, or flip the circuit breaker.
Leave it disconnected for about 5 to 10 minutes to allow the internal capacitors to discharge.
Plug it back in and try running a short rinse cycle.
If the code persists, it is time to move on to the physical checks.
Step-by-Step Guide to Fixing the E24 Error
1. Clean the Filter and Sump Area
The most common culprit for the E24 error is food debris clogging the filter system.
Locate the filter at the bottom of the dishwasher, twist it counter-clockwise, and pull it out.
Rinse it thoroughly under hot water to remove any grease or food particles.
Do not stop there; reach into the sump—the hole where the filter sits—and clear out any remaining debris or standing water.
A clean sump is essential for proper pump operation.
2. Inspect the Drain Pump
If the filter is clean, the issue is likely the drain pump impeller.
The pump is located near the sump area.
You may need to remove the plastic pump cover, which is often secured by a clip or a small screw.
Once you access the impeller—the small fan-like blades—ensure it spins freely.
Often, a piece of glass, a toothpick, or a chunk of food is lodged against the blades, preventing them from turning.
Remove the blockage and ensure the cover snaps back into place securely.
3. Check the Drain Hose
If the pump is clear, inspect the drain hose underneath your sink.
Check for any sharp bends or kinks that might be restricting water flow.
Additionally, ensure the hose connection to the garbage disposal or the sink's plumbing is not clogged.
If you recently installed a new garbage disposal, ensure the knockout plug was removed, as this is a frequent, often overlooked cause of drainage errors.
When to Call a Professional
If you have cleared the filter, checked the pump, and straightened the hoses, but the Bosch dishwasher E24 error code continues to appear, there may be a mechanical failure.
In some cases, the drain pump motor itself might have burnt out, or the main control board may be faulty.
These issues require professional diagnostics and specific spare parts.
If you are not comfortable handling electrical components or complex disassembly, it is safer to call an authorized Bosch service technician.
By following these steps, most homeowners can resolve the E24 error quickly.
Regular maintenance—such as cleaning your filters once a month—is the best way to prevent this error from returning and ensuring your dishwasher runs smoothly for years to come.

How often should I clean my dishwasher filter to prevent E24?
It is recommended to clean your dishwasher filter at least once a month to prevent food debris from building up and clogging the drain pump.
