Dishwasher displays E18 and does not fill with enough water; cycle may be noisy and ineffective.

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

• Fully open tap: Ensure the shutoff valve feeding the dishwasher is fully open.
• Straighten hose: Check behind the dishwasher for kinks or sharp bends in the inlet hose and correct them.
• Clean filters: Remove the hose from the tap and from the dishwasher inlet. Clean the small mesh filters thoroughly.
• Check household pressure: Verify that other taps in the home have normal pressure. If pressure is low, contact your water supplier or plumber.
• Test cycle: Reconnect everything, restore power and water, and run a short program to confirm that filling is normal and E18 is cleared.
