Dishwasher displays F4E3; unit may not fill properly or may stop mid-cycle with low water in the tub.

Safety: Turn off power and water supply before disconnecting hoses.

• Check water pressure: Run water at the kitchen sink; weak flow may indicate a plumbing issue. Correct low pressure before servicing the dishwasher.
• Inspect fill hose: Remove the lower kick plate and verify the fill hose is not kinked or crushed behind the dishwasher.
• Clean inlet valve screen: Shut off water, disconnect the supply line at the inlet valve, and clean the screen filter as described for F4E1.
• Test fill: Restore water and power, then start a cycle and listen for water entering. If the valve hums but little water flows, replace the inlet valve.
• Control check: If the valve never energizes and wiring is intact, the main control board may not be sending power and may require replacement.

Tip: Ensure the hot water line to the dishwasher is dedicated and not shared with heavily used fixtures that could starve it of pressure.
