An error code narrows the checks needed; it does not identify a replacement part by itself. Read the full code and the model number on the door edge before using the Bosch instructions for that model.
E15: stop and arrange a leak inspection
E15 indicates activation of the water-protection system. Close the water supply if safely accessible and stop using the dishwasher. Do not tilt the machine, bypass the protection or repeatedly reset it. Water in the base can reach electrical components, and draining it does not repair the leak.
E24 / E25: check the permitted drainage maintenance
Once the appliance is off, cool and safely isolated, clean the removable filter as described in its manual. Inspect only accessible hose sections for kinks; do not pull out a built-in unit. Wear gloves because glass may be present. A blocked sink connection, pump-cover problem or internal fault can produce similar symptoms.
E22, E09 and other codes
E22 commonly directs attention to the filter. E09 concerns the heating system and needs professional diagnosis. Do not order a heater or pump based only on a code. E01 / E02 meanings and procedures must be checked against the exact model documentation.
What to send when requesting help
Send the complete code, model label, whether water remains in the tub and when the fault appears. Mention any recent installation or plumbing changes. Ask about the diagnostic charge and parts availability before confirming a visit.

This is an editorial guide to owner checks, not a diagnosis of your appliance or a report of a repair we performed. Models and regions differ; your appliance manual and warranty terms take priority. Internal electrical, gas and sealed-system work requires an appropriately qualified professional.
