Problems you may notice
• Dishwasher fails to fill with water during the wash cycle
• Cycle stops prematurely and displays A10 error code on the control panel
• Water pressure appears weak or inconsistent during operation
• Dishwasher makes unusual humming or clicking sounds from the inlet area
• Cycle may not start at all when A10 error is present
• Dishes remain dry after running a complete cycle
Possible Causes
• Water supply valve under the sink is partially closed or turned off
• Inlet hose is kinked, pinched, or severely bent restricting water flow
• Water inlet hose is frozen (in colder climates or unheated spaces)
• Inlet hose filter screens are clogged with sediment or mineral deposits
• Water inlet valve solenoid has malfunctioned or failed
• Faulty water level sensor providing incorrect fill readings
• Low water pressure from your home's municipal supply (common issue with standard 120V North American systems)
• Control board malfunction preventing proper valve operation
• Internal inlet valve blockage from debris or mineral buildup
Precautionary measures
• Verify the water supply valve under your sink is fully open by turning the handle counterclockwise until it stops
• Inspect the inlet hose for kinks, bends, or pinches and straighten any obstructions
• Check that the inlet hose is not frozen, especially if the dishwasher is located in an unheated area
• Locate the inlet hose filter screens (at the connection points) and rinse them under running water to remove sediment
• Confirm the dishwasher door is fully closed and the door latch engages completely
• Check your home's circuit breaker to ensure the dishwasher breaker has not tripped
• Perform a hard reset by turning off the circuit breaker for 60 seconds, then switch it back on
• Run a test cycle with the dishwasher empty to observe if water fills properly
• Verify your home's water pressure is adequate by running your kitchen sink faucet at full pressure
• Ensure you are using the correct detergent type and amount for your model
• If the error persists after these checks, contact a professional appliance repair technician to diagnose potential valve or sensor failure
