Dishwasher does not fill with water and shows E18; you may hear a humming from the inlet valve.

Safety first: Turn off power and close the water tap before disconnecting hoses.

E18 indicates that the dishwasher did not receive enough water within the allowed time.

• Step 1 – Check tap and hose:
  • Ensure the water tap is fully open.
  • Disconnect the inlet hose from the tap and clean the mesh filter.
  • Straighten any kinks in the hose.
• Step 2 – Test water flow:
  • Briefly open the tap with the hose removed to confirm strong water flow from the household supply.
• Step 3 – AquaStop valve:
  • If the valve hums but no water flows, it may be blocked or defective.
  • Replace the AquaStop inlet hose assembly if cleaning the filter does not restore flow.

After resolving the supply issue, clear the error by restarting the dishwasher and running a short program.
