Safety Checks You Can Do
• Verify the main water supply valve under your sink is fully open by turning the handle counterclockwise
• Check that the inlet water supply hose is not kinked, twisted, or pinched behind the dishwasher
• Inspect the inlet hose connections at both the dishwasher and water supply for any leaks or loose fittings
• Locate and clean the water inlet filter screen by shutting off water, disconnecting the inlet hose, and rinsing the filter with clean water
• Ensure the dishwasher door closes completely and latches properly with an audible click
• Verify you are using the correct detergent type and amount recommended for your Asko model
• Run the dishwasher on a short cycle to test water flow
• Perform a hard reset by unplugging the dishwasher from the electrical outlet for 60 seconds, then plugging it back in
• Check that your home's water pressure is adequate (typically 20-120 PSI for dishwashers)
