Dishwasher quickly shows E17 during filling; may indicate overfill or high water pressure.

Safety: Turn off water and power before adjustments.

Steps:

• Measure water pressure: Use a pressure gauge at the dishwasher tap. If above manufacturer limits, install a pressure reducer.
• Partially close tap: As a temporary measure, slightly close the supply tap to reduce flow and test operation.
• Check inlet valve: If E17 persists at normal pressure, the inlet valve may be slow to close and should be replaced.
