Symptoms
• Dishwasher stops mid-cycle and displays E23 error code on the control panel
• No water or insufficient water filling the wash tub during the cycle
• Cycle does not complete and dishes remain unwashed
• Water may leak from under the dishwasher door
• Dishwasher makes unusual clicking or buzzing sounds from the valve area
• Error code appears repeatedly on restart attempts
Possible Causes
• Clogged or kinked inlet water hose restricting water flow
• Failed or stuck water inlet valve preventing proper water admission
• Low household water pressure below the minimum 20 psi required by USA models
• Debris or sediment blocking the inlet valve filter screen
• Faulty water level sensor not detecting adequate fill
• Tripped household circuit breaker cutting power to the inlet valve solenoid
• Broken or loose water inlet hose connection at the back of the dishwasher
• Defective control board failing to signal the inlet valve
• Mineral buildup in the inlet valve from hard water conditions common in USA regions
Safety Checks You Can Do
• Check your home's main water shutoff valve and any secondary shutoffs near the dishwasher to ensure they are fully open
• Verify household water pressure is adequate by checking a kitchen sink faucet for normal flow; if low, contact your water utility
• Inspect the inlet hose at the back of the dishwasher for kinks, pinches, or damage and straighten if needed
• Disconnect the inlet hose from the water supply connection and flush it into a bucket to check for debris or blockages
• Check that the home circuit breaker powering the dishwasher has not tripped; reset if necessary
• Open the dishwasher door and inspect the inlet valve filter screen (usually located on the inlet valve assembly) for visible debris or sediment and rinse gently if accessible
• Ensure the detergent dispenser door closes properly and is not blocking water flow
• Try running the dishwasher on a shorter cycle to see if the error reoccurs or if normal operation resumes
• Power cycle the dishwasher by turning it off at the circuit breaker for 30 seconds, then turning it back on to reset the control board
