Safety Warning

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Household water pressure too high, Faulty pressure regulator in inlet assembly, Blocked pressure chamber causing a false reading, Control misinterpreting pressure sensor

How to Fix / Troubleshooting

Safety first: Turn off the power and water supply.

1. Check household pressure: If possible, measure the water pressure at a nearby faucet. If it is above manufacturer recommendations (often 0.3–10 bar), install a pressure reducer on the supply line.
2. Inspect inlet assembly: Access the side of the dishwasher to locate any built-in pressure regulator or chamber. Clean out any debris or scale.
3. Pressure sensor: If equipped, test the pressure sensor or switch for proper operation, and replace if faulty.

Persistent E17 with normal water pressure may indicate a control board issue, requiring professional service.
