• Turn off the dishwasher and unplug it from the electrical outlet, or switch off the dedicated circuit breaker for 60 seconds, then restore power to reset the error code.• Verify the water supply valve under the sink (usually a small knob or lever behind or beside the dishwasher) is fully open by turning it counterclockwise.• Check that your home's main circuit breaker for the dishwasher is not tripped; switch it fully off and back on if needed.• Inspect the inlet hose at the back of the dishwasher where it connects to the water supply, ensuring it is not kinked, twisted, or pinched.• Gently pull the dishwasher away from the wall and look for any visible water leaks around the hose connection points and tighten by hand if loose.• Remove the inlet hose screen filter by turning off the water supply valve, unscrewing the hose connection at the back of the dishwasher, and checking the small screen for mineral deposits or debris; rinse with clean water.• Run a test fill cycle after reconnecting the hose to confirm water enters the tub properly before the error recurs.• Check that your home's water supply valve (main shutoff) in the basement or utility area is fully open.• Ensure the dishwasher door is closing completely and latching with an audible click before starting a cycle.• Clean the floor drain or garbage disposal connected to the dishwasher drain line to ensure proper backpressure sensing during filling.
