Symptoms
• Dishwasher stops mid-cycle and displays E22 on the control panel
• No water or very little water enters the dishwasher during the wash cycle
• Dishes remain dry or only partially wet after the cycle completes
• Error code appears immediately after starting a wash program
• Dishwasher beeps and halts operation when E22 displays
• Water fills very slowly compared to normal operation
Possible Causes
• Clogged or kinked inlet hose connecting the water supply to the dishwasher
• Water inlet valve malfunction or failure
• Debris or mineral buildup in the water inlet filter screen
• Home water supply turned off or shut-off valve under the sink in closed position
• Low household water pressure (below 20 psi typical for dishwasher operation in USA homes)
• Faulty water level sensor or float switch
• Damaged inlet hose or cracked connection at the water supply line
• Frozen water line (in cold climates or garages)
• Control board malfunction affecting water inlet valve signals
Safety Checks You Can Do
• Check the shut-off valve under your kitchen sink to ensure it is fully open (turn counterclockwise)
• Verify your home's main water supply is turned on and check if other faucets and appliances have normal water pressure
• Inspect the inlet hose at the back of the dishwasher for kinks, bends, or visible damage
• Turn off the water supply valve under the sink and carefully disconnect the inlet hose to check for debris or mineral deposits in the hose opening
• Disconnect the inlet hose and run water into a bucket to verify adequate water pressure from your home supply (should fill quickly, not trickle)
• Power off the dishwasher at the circuit breaker for 5 minutes, then power it back on to reset the control board
• Ensure the dishwasher door is closing completely and the door latch is engaging properly
• Check that the detergent dispenser lid is not stuck or blocking water inlet flow
• Feel the inlet hose to ensure it is not frozen if the dishwasher is installed in a garage or unheated space
• Run a test cycle with the dishwasher empty to confirm whether water enters the tub at all
