Precautionary measures
• Power cycle the dishwasher: Turn off the circuit breaker supplying the dishwasher for 60 seconds, then turn it back on to reset the control board
• Verify the dishwasher door is fully closed and latched properly
• Check that your home's water supply valve (typically located under the sink) is fully open
• Inspect the inlet hose for kinks, bends, or crimping that could restrict water flow
• Remove and clean the fine mesh filter and spray arms to ensure water circulation
• Confirm you are using the correct dishwasher detergent in proper amounts
• Check your home's circuit breaker panel to ensure the dishwasher breaker has not tripped
• Run a test cycle to see if the error reoccurs
• If error persists after these checks, contact a professional appliance repair technician or appliance repair support service to diagnose the heating element or sensor
