Dishwasher shows E18 and does not fill enough; cycle may end quickly with poor washing results.

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

• Verify tap is fully open: Ensure the dishwasher's water tap is turned fully on.
• Clean inlet filters: Unscrew the inlet hose from the tap and the dishwasher. Remove and rinse the small mesh filters at both ends.
• Straighten hose: Check the entire length of the inlet hose for kinks or compression behind cabinets. Re‑route if necessary.
• Test water flow: With the hose disconnected from the dishwasher and held over a bucket, briefly open the tap to confirm strong flow.
• Check inlet valve: If flow from the tap is good but the dishwasher still shows E18, the inlet valve may be partially blocked or failing and should be replaced.
