Bosch appliance error codes: what the display can tell you
A Bosch error code points toward a system that needs attention, not automatically to a part that needs replacing. Before you clear the display, photograph the complete code and the appliance’s E-Nr model number. Here are practical examples from Bosch dishwasher support guidance, plus the limits of what you can safely check at home.
Find the Bosch E-Nr before interpreting a code
Bosch uses model-specific instructions. The E-Nr on the rating label is more useful than a generic appliance description, especially when a model has been revised over several years. Record the full suffix, the fault code, and what the dishwasher was doing when it stopped.
E15 — leakage protection activated
On supported Bosch dishwashers, E15 means the leakage-protection system has detected water in the base area. Stop the programme, turn off the water supply if you can do so safely, and seek an inspection. Tilting the appliance or repeatedly resetting it without identifying the leak risks another overflow.
E24 or E25 — drainage problem
These dishwasher codes can point to a blocked drainage path, pump-cover problem or pump obstruction. With the dishwasher isolated and according to the correct manual, you may check the visible filter and accessible drain hose for a kink. Do not put fingers into a powered pump housing or dismantle a built-in machine to reach electrical connections.
E16, E17 and E18 — filling or water-flow concerns
A water-supply problem can involve a closed tap, restricted inlet hose or internal sensing fault. Check whether the household water supply is on and the inlet hose is visibly crushed; stop there if a panel must be removed. Water pressure or flow-meter problems need appropriate testing.
E09 and heating complaints
A dishwasher that finishes with cold dishes, takes unusually long or reports a heating fault may have an element, circulation, wiring or sensor issue. The code alone is not a quotation for a heater. Testing electrical resistance or live components belongs to a qualified technician.
When a code disappears after a reset
A temporary interruption can sometimes clear, but a recurring code is evidence the underlying condition remains. Do not keep restarting a machine that leaks, trips the circuit or smells hot. Note how soon the code returns and whether water remains in the base or tub.
What to send with a repair enquiry
Share a readable E-Nr label photo, the code and any flashing symbol, the symptom before the code, and your Ballito-area suburb or estate. For a built-in dishwasher mention whether the plinth or cabinetry limits access. We can confirm whether an assessment is appropriate and what booking information is needed.
Check the manufacturer instructions
Error-code meanings can change between model families. Use the official reference as a starting point and confirm your own appliance model before trying any owner-access check.

Frequently asked questions
Does Bosch E15 mean I should replace the dishwasher?
Not necessarily. It signals a leak-protection event on applicable models; the source and extent of any leak should be identified before deciding.
Can I clear an E24 fault by cleaning the filter?
Sometimes an accessible filter obstruction contributes, but E24 can also involve hoses, pump covers or internal faults. Follow the specific model instructions.
Do E24 and E25 always indicate a broken pump?
No. Drainage restrictions and pump-cover issues may produce similar indications; testing is needed.
Where do I find the E-Nr?
Look for the Bosch rating label, commonly near the door edge on a dishwasher. Photograph the complete identifier.
What if the dishwasher is leaking onto the floor?
Stop use, isolate electricity only if safe, turn off the water supply and arrange a safe assessment.
Can you identify the needed part from a code photograph alone?
A photograph helps triage but does not confirm which component failed.
Do Bosch washing machines use the same error meanings?
No. Code meanings vary by appliance family and model. Use the manual for the exact machine.
Will an appointment be available today?
