Possible Causes

Loose or damaged external water supply hose, Cracked plastic water inlet fitting, Leaking water inlet valve body, Overpressure in supply line

How to Fix / Troubleshooting

Safety: Immediately turn off the water supply and disconnect power.

  • Inspect supply hose: Check the entire length of the hose from the shutoff valve to the appliance for cracks, bulges, or loose connections. Replace if damaged.
  • Check inlet fittings: At the back of the unit, inspect the plastic inlet fitting and valve for signs of dripping or mineral deposits. Tighten connections gently.
  • Test under pressure: Place a dry paper towel under suspect areas, turn water back on, and watch for dampness.
  • Replace leaking parts: If the valve body or fitting is cracked or seeping, replace with the correct Miele-approved component.

Note: Consider installing a pressure regulator if household water pressure is excessively high.
