• Verify the circuit breaker for your dishwasher is in the ON position at your home electrical panel• Check that the water supply shut-off valve under your sink is fully turned counterclockwise to the open position• Inspect the inlet hose from the sink valve to the dishwasher for kinks, pinches, or bends that could restrict water flow• Disconnect the inlet hose at both ends and visually inspect the screens inside the connectors for white mineral buildup; clean with a soft brush if needed• Remove and clean the dishwasher filter and spray arms to ensure they are not clogged with debris• Verify that your dishwasher door is fully closed and latched securely• Confirm the drain hose is not kinked and that your garbage disposal (if connected) is not clogged or in locked position• Perform a hard reset by unplugging the dishwasher from the outlet for 60 seconds, then reconnecting it• If you have a 240V model, check that both breakers are in the ON position• Run a short test cycle after each check to see if the error clears
