Error code F5 on Asko dishwashers indicates a water inlet or fill system malfunction. This error means the dishwasher is unable to fill properly with water or is detecting an issue with the water supply valve.
• Dishwasher fails to fill with water during the wash cycle
• Cycle stops prematurely and displays F5 error code
• Water drains immediately after partial fill
• No water spraying from wash arms
• Error code appears repeatedly after attempting to restart
• Dishwasher may make clicking or humming sounds from the inlet valve area
• Dishes remain dry and unwashed after cycle completion
🔧
Possible Causes
• Water inlet valve malfunction or failure
• Kinked or pinched water inlet hose
• Clogged water inlet filter screen (located at the connection point)
• Main water supply valve to dishwasher is closed or partially closed
• Water pressure too low for proper fill detection
• Faulty water level sensor
• Door latch not fully engaged, preventing fill cycle initiation
• Float switch stuck or malfunctioning
• Damaged or loose water inlet hose connection
• Control board issue preventing valve activation
✅
Safety Checks You Can Do
• Verify the main water supply valve under the sink is fully open by turning it counterclockwise
• Inspect the inlet hose for kinks, bends, or damage and straighten as needed
• Check that the inlet hose connections are tight at both the water source and dishwasher
• Locate the inlet filter screen (typically at the water inlet connection) and rinse it under running water to remove debris or mineral buildup
• Ensure the dishwasher door is closing completely and latching with an audible click
• Confirm you are using the correct dishwasher detergent (not hand soap or laundry detergent)
• Empty the dishwasher completely and run it empty to observe if water enters the tub
• Reset the dishwasher by unplugging it from the electrical outlet for 60 seconds, then plugging it back in
• Run a test cycle to determine if the error code has cleared
• Check water supply line for any leaks or water pooling under or near the dishwasher
