Bosch Dishwasher Error Code E24: Causes, Checks & Repair
Bosch dishwasher error code E24 means the appliance is not draining properly. A blocked drain path or loose pump cover may be responsible; E24 alone does not confirm pump failure. Check accessible components using your model’s instructions. If the error returns, arrange a diagnosis before replacing parts.
Key Takeaways
E24 identifies a drainage problem, not a specific failed part.
A clean filter does not rule out a restriction elsewhere.
Record when the code appears and what you checked before requesting service.
What Can Cause Bosch Dishwasher Error E24?
Filter debris
Food residue can obstruct drainage. Inspect the filter before assuming an internal failure.
A restricted drain hose
A kink or blockage can prevent wastewater from leaving the dishwasher.
A loose pump cover or pump obstruction
The cover must be secured correctly. Debris around the impeller may also interfere with draining.
A blocked disposal connection
If E24 began after garbage disposal installation, its dishwasher connection may still contain the knockout plug.
These are possible causes, not a diagnosis for every Bosch model. Bosch’s dishwasher error-code guide explains the checks associated with E24.
What Can You Check Safely?
1. Prepare the Dishwasher
Stop the cycle and disconnect power before accessing the filter or pump area. Let hot water cool. Avoid reaching blindly into standing water: sharp debris may be present.
2. Clean and Reinstall the Filter
Follow your owner’s manual to remove and clean the filter assembly. Refit it securely. If the error started immediately after cleaning, mention that sequence when requesting help.
3. Check the Pump Cover
Inspect the cover only as described in your model’s homeowner instructions. Make sure it is properly secured. Stop if access requires force, panel removal, or unfamiliar disassembly.
4. Inspect Accessible Connections
Look for a visible kink beneath the sink. If a disposal was recently replaced, ask the installer to verify its dishwasher connection. Leave hose disconnection and removal of the built-in appliance to someone equipped for that work.
Bosch’s operating instructions cover filter maintenance, pump access, and troubleshooting for the models listed in that document. Use the manual matching your dishwasher.
Why Does E24 Return After Cleaning or Resetting?
Cleaning one component does not confirm that the entire drainage path is clear. Repeated E24 needs a fresh assessment rather than another assumption about the filter.
Before booking, note whether water remains in the tub, when the error appears, and whether it followed cleaning or installation work. Share what changed after each check. This gives the technician a clearer starting point.
Use only your model’s reset procedure after addressing the identified issue. Clearing a code does not remove a physical blockage.
When Should You Book Dishwasher Repair?
Arrange professional dishwasher repair if E24 returns after the permitted checks, the appliance still cannot drain, or further inspection requires removing the unit.
Stop using it if you notice leakage or a burning smell. If the kitchen sink also backs up, report that separately so the household drainage connection can be considered.
A useful diagnosis establishes where drainage is restricted and whether a component has failed. Ask what the inspection found before approving replacement parts.
Frequently Asked Questions
Does E24 Mean I Need a New Drain Pump?
No. A Bosch E24 error can involve several drainage components. The code by itself is insufficient to choose a replacement part.
Can I Keep Restarting the Dishwasher?
Repeated restarts are not a repair. If E24 returns after the appropriate checks, stop repeating the cycle and arrange diagnosis.
Is E24 the Same as E15?
No. E24 concerns drainage; Bosch E15 concerns activated leak protection. Read our Bosch E15 guide if that is the code displayed.
