Bosch Dishwasher E16, E17 or E18 Code: Water Not Filling
Updated
Short answer
What E16, E17, E18 means
In Bosch's words, condensed: an issue with water flowing into the dishwasher or the filling system; for E18, the water level is too low or water is not being pumped correctly (Bosch).
What Bosch says to try
- Check the inlet hose is not kinked or damaged.
- Make sure the water supply is turned on; Bosch says the flow rate should be 10 liters per minute.
- Contact Bosch support if it continues.
Unplug the appliance or switch off its breaker before reaching into any part of it. Codes and steps vary by model, so check your manual too.
If the code comes back
With the water on and a straight hose, the inlet valve and flow meter are the next checks (Bosch's E14 is a flow meter failure). Dishwasher hose replacements run $75 to $130; sensor repairs $100 to $200. (Angi, dishwasher repair cost (updated Apr 6, 2026))
