Bosch E24 means the dishwasher is having trouble draining. If cleaning the filter has not helped, check the pump cover under your model's instructions and consider whether the problem began after a plumbing change. A disappearing error or an illuminated CLEAN light does not, by itself, confirm that the wash finished.
This guide covers Bosch dishwashers displaying E24 or E:24. E25 can also involve a blocked pump or an unsecured cover; the code alone is not a reason to buy a pump. Use your exact model's manual for access and controls.
Disconnect power before permitted filter or sump maintenance and let hot water cool. Sharp debris can hide below the filter. Leave glass removal, inaccessible blockages, panel removal and electrical testing to a qualified technician. Stop for leaks or repeated breaker trips.
Filter clean, but E24 remains?
The filter and the drain pump cover are separate pieces. Refitting the filter does not establish that the cover beneath it is secured. Locate the cover in your model's manual; do not remove a similar-looking piece by guesswork.
Where the manual shows a click-fit cover, make sure it is fully seated. Do not force a distorted cover or assume that every Bosch design uses the same attachment. A damaged or missing cover needs model-specific support.
A SMS50E06UK owner in the UK reported repeated E24 despite cleaning and apparent recoveries. The owner eventually found a bowed cover with a damaged edge sitting incorrectly. After replacing it, they reported no further problem at that update. That supports checking the cover's condition; it does not establish a US part match or identify the cause in another machine.
Did the trouble start after plumbing work?
After a new garbage disposal is fitted, ask the installer to check whether its dishwasher inlet plug was removed. A clean filter cannot compensate for a sealed outlet connection.
With an older installation, inspect only accessible hose routing and the air gap, if fitted, as your instructions allow. Visible kinks or obstructions need attention. Our dishwasher not draining guide covers the broader water-path checks. Do not pull out a built-in appliance or disconnect its plumbing to follow a generic diagram.
If a hose extension was added, ask about compatibility as well as routing. Bosch's drain-service guidance lists unsuitable hose as a separate problem from a kink or clog. Have the installer check the fitted extension against your model's installation instructions. Hose color alone is not a diagnosis, and an extension listed for another model is not automatically suitable.
CLEAN is lit, but water remains
For the drainage fault described in Bosch's service guidance, the CLEAN light can come on as an abnormal-pump safety response even though the cycle has not completed. This does not mean that every CLEAN indication is a fault.
If water remains above the filter screen or the wash stopped unexpectedly, note both the light and what happened during the cycle. Do not use the light alone to mark the problem solved. Continued drainage trouble needs the permitted checks or service.
The error cleared, but the cycle still stops
Keep three observations separate: water drained, the code disappeared, and the selected wash completed. A successful drain answers only the first question. If the timer stops advancing without E24 returning, report that changed symptom rather than simply saying “E24 fixed.”
For example, a SHEM63W55N/11 owner removed debris and lost the E24 message, yet Normal and Rinse still stalled. A breaker reset did not help. Later, a drain check worked, followed by successful Speed60 and usual cycles. No part was replaced and no cause was established. That history demonstrates the difference between clearing a code and restoring the wash; selecting another cycle is not a proven repair.
Other outcomes also deserve caution:
- Ascenta, exact model unknown: glass removal helped temporarily. Further filter and impeller cleaning failed; a new drain pump helped for weeks before E24 returned. Later cleaning still did not settle it. A suggested sensor fault remained unconfirmed.
- SGE63E05UC: drain-path checks and temporary recoveries preceded a pump replacement. The new pump was quieter, but E24 persisted. The owner eventually replaced the dishwasher without a confirmed component diagnosis.
These reports do not establish how common any cause is. Neither a quieter replacement pump nor one successful cycle proves that an intermittent problem has gone away.
Does your display show E6102 or E6103 instead?
Record the complete display and full model number rather than translating an extended code to E24 from a generic chart. Bosch's public US code list describes E6103 as a filter blockage, while its drain-service sheet pairs E6103 with E25 and pump/cover trouble. The descriptions are not consistent enough to use as a universal conversion.
Use your exact model's manual or ask Bosch to identify the applicable instruction. Do not choose a replacement part from that conversion alone. This also avoids treating a model number from someone else's repair story as your machine's specification.
What to give the technician
If E24 keeps returning after the permitted checks, arrange model-specific service. Give the full model number, exact displayed code, cycle name, when it stopped, whether water remained above the filter, and what changed after the last attempted fix. Include a newly fitted disposal or hose extension if relevant.
If the display changes to E15, switch to the leak-protection path. Bosch identifies E15 with water in the base: turn off the water inflow and contact support. Do not repeatedly restart or tip the appliance to clear that warning.
