Problems you may notice
• Dishwasher fails to fill with water at the start of the cycle
• Cycle stops prematurely or doesn't complete
• Error code A1 displays on the control panel
• Dishes are not being washed and remain dry
• Water does not spray from the spray arms
• Dishwasher may beep or alert you during operation
• The door may lock without the cycle proceeding
Possible Causes
• Water supply valve behind the dishwasher is turned off or partially closed
• Inlet hose is kinked, pinched, or twisted
• Inlet hose is frozen (in colder climates or during winter months)
• Water inlet filter screen is clogged with mineral deposits or debris
• Incoming water pressure is too low (common in some USA regions with low water pressure)
• Water inlet valve has failed or is not opening properly
• Electrical connection to the inlet valve is loose or corroded
• Household circuit breaker has tripped
• Control board malfunction preventing proper valve activation
Precautionary measures
• Check your household circuit breaker panel and reset any tripped breakers, then attempt to run the dishwasher again
• Turn off the dishwasher using the power switch, wait 60 seconds, then turn it back on to perform a full reset
• Locate the water supply valve behind or beneath your dishwasher and ensure it is fully turned counterclockwise (open position)
• Inspect the inlet hose along its entire length for any kinks, sharp bends, or pinches that could restrict water flow
• Check that the inlet hose is not frozen if you live in a cold climate; allow it to thaw naturally if needed
• Remove and visually inspect the inlet hose connection points at both the wall valve and dishwasher for any visible damage or corrosion
• Open the dishwasher door and pull out the lower rack to access the filter area; remove any visible debris or mineral buildup
• Ensure the spray arms rotate freely by hand and check that their holes are not blocked by food particles or mineral deposits
• Verify that you are using the correct amount of dishwasher detergent for your water hardness level
• Run your kitchen faucet to confirm adequate water pressure is reaching your home
• If the error persists after completing these checks, contact a professional appliance repair technician who can diagnose the water inlet valve and internal components
