Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Make sure the household water supply to the dishwasher is open.
Inspect the visible inlet hose for a kink, crushing, or obvious damage.
Record whether any recent plumbing or installation work occurred.
Do not open the inlet valve or internal flow-meter circuit as a homeowner check.
Important safety warning. Turn off the water and stop use if there is active leaking.

When to call a technician
If water supply and the visible inlet path are normal but the code returns, the fill valve, flow measurement, sensing, wiring, or control path needs diagnosis. When requesting service, include the complete Bosch model/E-Nr. Similar-looking dishwashers can use different controls, pumps, drying systems, and diagnostic logic.
