Bosch dishwasher showing an E24 error code? This common problem means your dishwasher isn’t draining properly. Causes include a clogged filter, blocked drain hose, or drain pump issue.
Use this guide for easy steps to fix the problem and stop future drainage issues.
What Does E24 Error Mean on Bosch Dishwasher?
The E24 error on a Bosch dishwasher signals a drainage failure, meaning water can’t properly exit the appliance. This issue often results from a clogged drain filter, kinked hose, or pump malfunction. Prompt action prevents further damage and restores normal operation.
Common Causes of Bosch Dishwasher E24 Error:
- Clogged drain filter: Trapped food debris can block water flow.
- Blocked or kinked drain hose: Bends or obstructions in the hose slow or stop drainage.
- Improper installation: Missing high loop or a plug in the disposal line can trigger E24.
- Faulty or loose pump cover: Misaligned covers can interfere with drainage.
- Defective drain pump: Malfunctioning pumps can’t move water out efficiently.
How to Fix E24 Error on Bosch Dishwasher
If your Bosch dishwasher displays the E24 error, begin by checking drainage components in the following order. This will help you identify and resolve the underlying issue efficiently.
Step 1: Clean the Drain Filter Thoroughly
Start with the drain filter, the most common source of the Bosch E24 error. Food scraps and debris block water flow.
- Remove the bottom dish rack and twist the filter counterclockwise to detach it.
- Rinse under warm water and scrub with a soft brush to dislodge particles.
- Clean the filter housing inside the dishwasher, then reinstall the filter securely.
Step 2: Inspect and Clear the Drain Hose
A blocked or improperly installed drain hose often causes the E24 code. Kinks or leftover installation plugs can obstruct water.
- Check that the hose is not bent or twisted behind the unit.
- Disconnect the hose at both ends (sink and dishwasher) and run water through it.
- If connected to a garbage disposal, confirm that the knockout plug was removed.
Step 3: Check the drain pump and impeller
A jammed or broken drain pump impeller will trigger the Bosch dishwasher E24 message. Ensure it spins freely.
- Disconnect power and remove the lower front panel (kick plate).
- Locate the pump near the filter area and check for any debris or blockage.
- Replace the pump if it’s noisy, sluggish, or shows visible wear.
Step 4: Secure or replace the pump cover
If the pump cover beneath the filter is loose or broken, water won’t drain properly.
- Access the cover under the filter and inspect it for damage.
- Ensure it locks into place without movement.
- Install a new cover if the original is cracked or missing clips.
Step 5: Reset the dishwasher
Sometimes, the Bosch dishwasher E24 error can result from a temporary glitch. A simple reset may clear it.
- Press and hold the “Start” button for 3 to 5 seconds until the dishwasher resets.
- Or, unplug the unit for five minutes, then reconnect.
- Start a short wash cycle to confirm whether the issue persists.
How to Prevent E24 Error on Bosch Dishwashers
Preventive maintenance helps avoid the E24 error. Keep the dishwasher clean and check the components regularly.
- Clean the drain filter weekly and scrape off food debris before loading the dishes.
- Ensure the drain hose has a proper high loop or air gap and remains free of blockages.
- Don’t overload the dishwasher. Also, avoid using too much detergent. This can cause buildup and block the flow.
