Dishwasher displays E18; the unit fills only partially or stops with a low water level in the tub.

Safety first: Disconnect the power and turn off the water.

• 1. Clean inlet filter: Shut off the water, disconnect the inlet hose at the valve, and remove and clean the small mesh filter.
• 2. Check hose routing: Ensure the inlet hose is not kinked or pinched behind the dishwasher.
• 3. Verify water pressure: Confirm that other fixtures have good flow. If the pressure is low, consult a plumber.
• 4. Flow meter: If the physical water level looks normal but E18 appears, the flow meter may be miscounting and should be cleaned or replaced.

After cleaning and correcting supply issues, run a test cycle to confirm normal filling.
