Bosch Dishwasher E24 or E25: What to Check Before Calling
Understand Bosch E24 and E25 drain warnings, safe filter checks, installation clues and when to arrange dishwasher repair in Orange County.
Quick answer
Bosch E24 points to a drainage problem. E25 can indicate an obstructed drain pump or a loose or missing pump cover. Neither code alone proves that the pump needs replacement. Record the exact code and model, check only the owner-maintenance items in your manual, and arrange diagnosis if the warning returns.
| What you notice | Next step | Avoid |
|---|---|---|
| E24 with water left after a cycle | Note when the cycle stops and whether the sink also drains slowly. | Avoid repeatedly restarting a full cycle. |
| E25 after filter cleaning | Check the manual for correct filter and pump-cover seating. | Do not force a cover or reach into the pump. |
| Problem began after a disposal installation | Tell the installer or technician about the recent work. | Do not dismantle the disposal yourself. |
Start with the exact code and E-Nr
A photo of the display is more useful than a remembered number. Record whether it reads E24, E:24, E25 or a different warning, then find the Bosch E-Nr on the appliance label. Include the complete number and its suffix when requesting help. Different dishwasher generations have different controls, filter assemblies and access instructions.
Describe what happened before the warning: a normal wash, the first cycle after installation, filter cleaning or a new garbage disposal. Say whether water remains across the tub floor or only in the recessed filter area. A little water below the filter is different from a tub that has failed to drain. These observations help establish the next check without ordering a part from the code alone.
Safe checks before booking a visit
Stop the dishwasher and let hot water cool. Before handling a removable filter, disconnect power using the safe method in the model manual. If you cannot safely isolate power or identify the correct assembly, leave the work to a technician. Remove and rinse only the filter components that the manual identifies as user-serviceable. Refit them correctly before use.
Broken glass can hide in standing water. Do not probe blindly with your fingers, use drain chemicals or force an unfamiliar pump cover. A pump-cover procedure shown for another Bosch model may not fit yours. If the filter is clean but the warning returns, further dismantling is not the next homeowner check.
From an accessible, dry location, note whether the kitchen sink drains normally and whether an exposed hose appears crushed. Do not pull a built-in dishwasher out or disturb wiring and plumbing to look behind it. A sink backup or leak needs attention beyond simply clearing a dishwasher display.
Why recent installation work matters
Bosch lists a blocked drain hose, a dirty filter and an unremoved garbage-disposal connection plug among E24 possibilities. E25 guidance also highlights the drain pump and its cover. Report recent disposal replacement, sink work or dishwasher movement even if the appliance worked before that appointment.
The installation history changes what needs checking; it does not establish who caused the fault. An installer may need to verify the drain connection, while an appliance technician evaluates the machine. Keep the installation invoice and avoid buying a pump before the drainage route and model-specific assembly have been assessed.
What diagnosis should establish
A useful diagnosis distinguishes a restriction outside the appliance from an obstruction or malfunction inside it. Explain whether you hear a hum, gurgle or repeated attempt to drain, but do not treat a sound as proof of a failed motor. The technician should identify the affected area and explain the proposed work before you approve a repair.
If the same code returns after a permitted cleaning step, stop repeating resets. Photograph the warning, note the cycle and tell us which checks you completed. If water is leaking onto the floor, stop use and avoid wet electrical areas. Resolving the cause is more important than making the code disappear once.

Common questions
Does E25 always mean a bad pump?
No. Bosch also identifies an obstruction or a loose or missing pump cover. The code needs to be interpreted alongside the model and inspection.
Can I clear E24 by resetting the dishwasher?
A reset may clear a display without removing the drainage problem. Follow your exact manual only after the permitted check; arrange service if the fault returns.
Should I replace the dishwasher?
Get a diagnosis first. Compare the approved repair scope with the full replacement and installation cost rather than deciding from a warning alone.
