Bosch Dishwasher E18 — Water Inlet Checks

What E18 means

Bosch US describes E18 as an incoming-water problem: the level may be insufficient or pumping may be incorrect. This does not prove that the inlet valve needs replacement.

What Bosch recommends

The Bosch US E18 guide says to check the inlet hose for damage or kinks and confirm that the water supply is on. It specifies a flow rate of 10 litres per minute and directs further questions to Bosch support.

Use the checks within their scope

Confirm applicability in the documentation for your exact model and market. This page gives no hose-disconnection procedure or flow-measurement setup. If a check would require moving the installed machine, disconnecting plumbing or accessing electrical parts, stop and ask Bosch how to proceed for your model.

When to seek support

If the suggested checks cannot be completed or the error remains, contact Bosch through the linked guide. Have the full model number and exact displayed code ready. We do not infer a failed valve from this code or prescribe a multimeter test, component replacement or generic reset.

Limits of this guide

This review covers the cited US dishwasher entry only. It is not an appliance inspection or a repair certification. No repair price, completion time or successful outcome is established. For another market or a different displayed code, use the corresponding manufacturer documentation rather than transferring these checks automatically.
