Dishwasher does not fill or fills very slowly; E18 appears on the display.

Safety first: Unplug the appliance and close the water tap before disconnecting hoses.

• Verify tap is open: Ensure the water tap feeding the dishwasher is fully open.
• Clean inlet filter: Remove the inlet hose from the tap and clean the small mesh filter. Also check the filter at the dishwasher end if present.
• Check hose routing: Make sure the inlet hose is not kinked or crushed behind the machine.
• Test water flow: With the hose removed from the dishwasher, briefly open the tap into a bucket to confirm strong flow.
• Replace Aquastop if needed: If water flows from the tap but not through the Aquastop when the machine calls for water, the Aquastop hose assembly is likely defective and should be replaced.
