Safe first steps

  1. Check if the water tap is fully open.
  2. Inspect the inlet hose filter for blockages.
  3. If the filter is clogged, clean it thoroughly before reattaching.
  4. After cleaning, ensure all connections are secure and turn the water tap back on.
  5. If the error persists after these checks, arrange a service visit — do not run the appliance.

When to stop

  • Stop if you see water leaking from the inlet hose or connections — risk of flooding.

Likely cause

The water supply is blocked or insufficient. Check if the water tap is open and if the inlet hose filter is clogged.
