Dishwasher does not fill with enough water; spray arms barely rotate and pump sounds like it is sucking air.

Safety first: Unplug the appliance and close the water tap before removing panels.

• Check inlet filters: Clean the mesh filters at both ends of the inlet hose.
• Verify water pressure: Ensure the supply tap is fully open and household pressure is adequate.
• Inspect side tank and flow meter: Remove the side panel and check for blockages or heavy limescale in the water channels. Clean or descale as needed.
• Check pressure switch and hose: Clean the pressure hose and chamber to ensure accurate level detection.
• Test fill level: During a test cycle, open the door after filling; water should typically cover the filter area but not reach the door opening. If very low, further diagnosis of inlet valve and sensors is required.
