Dishwasher fills too quickly or indicates high inlet pressure, E17 displayed.

Safety first: Turn off water and power before modifying plumbing.

• 1. Check tap pressure: If water blasts from the kitchen tap, your pressure may be above the dishwasher's recommended limit.
• 2. Install or adjust pressure reducer: Fit a pressure-reducing valve on the dishwasher feed line if not already present, or adjust an existing one to around 2–4 bar as recommended.
• 3. Partially close tap (temporary): As a short-term measure, slightly close the supply tap to reduce flow, then test the dishwasher.
• 4. Inspect inlet valve: If E17 persists at normal pressure, the inlet valve may not be closing correctly and should be checked.

When to call a technician: For permanent pressure regulation or valve replacement, professional service is advisable.
