Bosch Dishwasher E18: Check Water Supply and Inlet Hose
THE SHORT ANSWER
Water inflow or water level is insufficient, or pumping is not correct.
Bosch describes E18 as a water-flow problem associated with a low water level or incorrect pumping. Its initial checks concern the inlet hose and an open water supply.
Confirm that the accessible dishwasher water shutoff is open.
Keep the check external. Do not disconnect hoses or work on electrical components.
WHAT YOU MAY NOTICE
Symptoms to record
- E18 appears while the dishwasher reports a water-flow problem.
UNDERSTAND THE POSSIBILITIES
Causes & useful observations
A code identifies a condition. It does not, by itself, confirm which part needs repair.
| Possible cause | What to look for | Safe check / next step |
|---|---|---|
| Restricted inlet hose | A visible kink or damage is present. | Look at the accessible hose routing. |
| Water supply not open | The shutoff may be closed. | Check the accessible water valve. |
| Unresolved filling or pumping issueService may be needed | The code remains despite the basic checks. | Request support rather than assume a failed part. |
WORK THROUGH THE BASICS
Safe troubleshooting checks
Use the checkboxes to keep track as you read. Stop at any warning or step that does not match your appliance.
Confirm the accessible dishwasher supply valve is open; do not force a stuck valve.
What to noteThe supply is available to the dishwasher.
Inspect for kinks or damage where the inlet hose is visible.
What to noteReport any obvious restriction.
Bosch’s page specifies a supply-flow requirement; have a professional assess it if needed rather than improvising a hose test.
What to noteFurther checks follow the exact installation requirements.
