Match the symptom, then work through the safe checks.
1. What best matches what you observe?
2. Complete only the checks that are safe for you.
Show stop conditions
- Water leaks at a hose or valve
- Water continues entering with power off
- Internal electrical testing is required
Likely causes
- Supply valve is closed or partly open
- Inlet hose is kinked, frozen, or restricted
- Inlet screen is blocked
- Water pressure or inlet valve is abnormal
Quick checks, in order
Confirm household water flow
Open the supply valve fully and verify a nearby tap has normal flow.
Inspect inlet hoses
Straighten kinks and check for freezing, crushing, or reversed connections.
Check user-accessible inlet screens
Turn off water first and follow the model manual.
Stop before valve or wiring work
Internal inlet-valve and electrical diagnosis requires qualified service.
What happens when E16 appears?
Focus on the supply, hose, screen, pressure, and inlet valve.
A partly closed valve, kink, low pressure, or restricted screen is likely.
A flow, pressure, sensor, or control fault may need service.
Stop and get qualified help when
- Water leaks at a hose or valve
- Water continues entering with power off
- Internal electrical testing is required
Official support and model manuals
Use the full model number from the rating label. The manufacturer manual is the deciding reference when codes differ by region or product family.
Frequently asked questions
What does E16 mean on a Bosch dishwasher?
On many model families, E16 indicates that uncontrolled water entry was detected. Confirm the exact model and region because the same display can be used differently.
Can I clear E16 by unplugging the dishwasher?
A short power reset may clear a temporary state, but it will not fix a blocked hose, leak, failed sensor, motor, heater, or wiring fault. Stop if the code returns.
Should I replace a part based only on the code?
No. A code identifies a system or condition, not always the failed component. Complete safe external checks and use the model-specific manual or qualified service.
