What Bradford White says to do
Press any button to silence the alarm, then clear the condensate drain by removing any drain lines and connections and clearing debris. Reattach drain lines and connections, then allow the water heater to run. The water heater will continue to produce hot water using the backup resistance heating elements until the condensate drain has been cleared.
