What to check first
Stop normal operation while this warning is active. Follow only the documented safe checks or protective-drain instructions for the exact model.
Basic checks
- Check the visible inlet hose for kinks or damage.
- Confirm the water supply is open if it is safe to access.
- Stop and use Bosch support if the inlet path looks normal.
Applicability
Regional guidance · Bosch dishwashers · United States
This scope follows Bosch's US dishwasher error-code list, which groups E16 and E17 as filling-system alerts; confirm the exact model manual and local support region.
Reset or retry steps
- The cited E16/E17 entry gives inlet-hose checks and support escalation, not a reset procedure; follow your exact model manual.
When to call a technician
- Call Bosch support if E16, E17, E3300, or E3400 returns.
- Call service if inlet access, valves, or internal filling parts are involved.
Before approving a paid visit, check warranty status and reviewquestions to ask before repair.
Can I keep using it?
Stop normal use when water is visible or a leak warning is active. Stay clear if water could reach wiring or controls.
- Safe next step
- Follow the code-specific shutdown or protective-drain instructions, turn off water when appropriate, and avoid repeated resets. Do not interrupt a documented protective-drain sequence just to clear the display.
- Stop when
- Water is near wiring, cabinetry is getting wet, the leak returns, or the source is not safely visible.
Do not keep using the appliance if the code points to voltage, wiring, control power, burning smell, smoke, or a possible miswired supply.
- Safe next step
- Use only safe owner-level power checks, then involve a qualified technician or electrician when the source points to wiring or supply voltage.
- Stop when
- Breakers trip, lights dim, the appliance smells hot, wiring may be miswired, or the warning returns after a safe reset.
Safety boundaries
Safe first
- Match the exact brand, appliance type, and displayed code first.
- Use the model manual as the final authority for access steps.
- Stop and address visible water before retrying the appliance.
- Disconnect power before any service-access step.
- Turn off water before disconnecting any hose.
Do not do this
- Do not continue normal cycles while this code is active; any protective-drain sequence must follow the exact model instructions.
- Do not disconnect inlet hoses until the water supply is off.
- Do not bypass locks, float switches, leak sensors, or other safety systems.
Common causes include
- Inlet hose kinked or damaged
- Another filling-system condition requiring Bosch support
FAQ
What does Bosch Dishwasher code E16 usually mean?

Can I keep using the dishwasher with code E16?
Stop normal operation until the issue and safety warnings have been addressed. Follow only the documented safe checks or protective-drain instructions for your model. Turn off water before hose work.
When should I call a technician for Bosch E16?
Call Bosch support if E16, E17, E3300, or E3400 returns. A qualified technician may check the listed symptoms and source guidance against the model's service information before treating any part as failed.
