Dishwasher shows E18; not enough water in tub, short fill time

Safety first: Disconnect power and close the water tap before removing hoses.

• Fully open tap: Ensure the water supply tap is fully open and not restricted by a faulty valve.
• Clean inlet filters: Remove and clean all mesh filters in the inlet hose and valve connection.
• Straighten hose: Make sure the inlet hose is not kinked or crushed behind the dishwasher.
• Check flow meter: Inspect and, if necessary, replace the flow meter in the side water matrix if it is not registering correct flow.
• Test cycle: Reassemble and run a short program to confirm that the water level is adequate and E18 is cleared.
