Bosch US groups E16 and E17 as water-inflow/filling-system issues. After installation, begin with visible supply and hose context; the code alone does not identify an inlet valve to replace.
Bosch US dishwasher code guidance for the displayed code. Match the full E-Nr and its own manual; the same short number in another appliance category, market or generation must not be assumed equivalent.
Stop and isolate power before permitted user maintenance, and let water cool. Watch for sharp debris. Do not reach blindly into a sump, open electrical panels or use drain-opening chemicals. Stay clear of water near electrical equipment.
Trace the supply and the reported state
Record any recent installation changes and the visible supply checks. If the code continues, use Bosch’s guidance for the exact E-Nr and market; E16 and E17 should not be treated as a universal diagnosis of one valve.
| Observed state | Interpretation / next step |
|---|---|
| First-use code | Ask installer to verify supply/routing. |
| Visible kink or damage | Have the installation corrected safely. |
| No external issue found | Model-specific filling diagnosis. |
Code-specific checks
Use the installation timeline
Record whether the dishwasher has ever completed a program since installation. Include any recent shutoff-valve, plumbing or cabinet work. An immediate first-use fault and a new fault after months of operation deserve different histories even if the display is identical.
Check only what is accessible
Confirm the water supply has been restored and look for a visible kink or damage in the inlet hose. Do not tug a built-in appliance out to inspect concealed connections. Have the installer verify the actual installation when access is restricted or routing was recently changed.
Do not import a universal overfill definition
Code descriptions can differ across markets and models. Bosch US groups E16 and E17 as filling-system issues; that does not mean every E16 or E17 identifies the same internal valve fault. Match the manual and market to the full E-Nr.
Choose the right escalation
If an installer corrects an external supply issue, record the correction and whether normal operation returns. If accessible checks reveal nothing or the code continues, ask Bosch/qualified service for a matched diagnosis. A visible clear hose does not establish correct inlet operation. Do not run repeated cycles when water is continuously entering or leakage appears; safely close the supply and arrange service.
If the warning returns
Recent installation + visible supply issue → installer
Persistent code without an external explanation → Bosch service.
When to stop and get help
Only carry out maintenance permitted in your model’s manual. For service, note the full model number and suffix, displayed code, selected cycle and what happened during the checks. Leave internal wiring, gas components, pumps and safety devices to a qualified professional. A symptom alone does not identify a failed part.
