How to Fix / Troubleshooting

Safety first: Disconnect the power and close the water tap.

  • 1. Fully open tap: Confirm that the supply tap is fully open and not partially closed.
  • 2. Clean inlet filter: Remove and clean the mesh filter at the hose connection, as described for E02.
  • 3. Check hose for kinks: Straighten any sharp bends or kinks in the inlet hose.
  • 4. Inspect water matrix: Remove the side panel and check for partial blockages in the water matrix. Descale if necessary.

When to call a technician: If E18 persists despite a good water supply, the inlet valve or flow meter may need replacement.
