If E25 first appears after maintenance, the pump-cover fit is a relevant documented branch. Bosch includes a loose or missing cover in its E25 guidance. Only use the access and refitting method permitted by the exact E-Nr manual; a cover from another model is not assumed compatible.
Selected Bosch dishwashers code family. Confirm the exact model and displayed characters; similar codes on other appliances are not interchangeable.
Stop and isolate power before permitted user maintenance, and let water cool. Watch for sharp debris. Do not reach blindly into a sump, open electrical panels or use drain-opening chemicals. Stay clear of water near electrical equipment.
Follow the drain path
Check the parts of this route that your manual permits you to access. Note where water flows and where you cannot confirm it. Do not open covers or components that require service access.

Code-specific checks
Make access safe
Stop the appliance, isolate power and allow the water to cool. Do not blindly put fingers into a sump that may contain broken glass.
Use the exact cover instructions
Only inspect or refit a pump cover if the model manual describes user access. Cover designs vary; do not pry a component based on another dishwasher’s layout.
Escalate unresolved faults
If a cover is missing, damaged or inaccessible, arrange service and verify the correct part by E-Nr. If the code persists after proper refitting, further diagnosis is needed.
If the warning returns
Code after cleaning → verify cover by manual
Damaged/missing cover → verified part and service
Recurring code → pump/drain diagnosis.
When to stop and get help
Only carry out maintenance permitted in your model’s manual. For service, note the full model number and suffix, displayed code, selected cycle and what happened during the checks. Leave internal wiring, gas components, pumps and safety devices to a qualified professional. A symptom alone does not identify a failed part.
Should I buy a pump before checking the cover?
No. Bosch specifically includes a loose or missing cover in its E25 guidance.
