Bradford-White Corp ULTRA HIGH EFFICIENCY COMMERCIAL GAS WATER HEATER Error, Definition of Code

Error	Definition of Code	Cause of Problem and Actions Taken to Correct
Code
		Burner is either not lighting or not staying lit during ignition cycle. Check inlet
		gas pressure for minimum pressure on rating label. Can you hear sparking to
		the burner? Check high voltage cable connections. Check inlet gas pressure
		to the gas valve making sure the pressure is within the limits specified on the
		rating label. Check gas valve wire harness for broken wires or shorts. Check
		outlet gas pressure. If 24 volts is present to the terminals at the gas valve,
	Maximum Number of	replace gas valve. Check for voltage output to the blue gas valve wires on the
62		control board pins. If during the ignition trial period, there is no voltage present
	Retries Detected
		at the control board pin terminals for the blue wires leading to the gas valve,
		then replace the control board. Replace spark rod if insulator is damaged or
		rod is loose. Check to make sure combustion blower is operating when
		thermostat calls for heat. If blower is not running check for 120 volts to blower
		harness and then at blower pin connections. Replace control, wire harness, or
		blower if defective. Check to make sure vent terminals are clear of debris or
		snow and ice. Make sure the condensate drain flows freely.
		Burner flame is lost during run cycle, then re-established on ignition cycle.
		Check inlet gas pressure. Is gas pressure dropping below the minimum
		operating pressure on the rating label after the gas valve opens? Is the gas
	Maximum Number of	pipe size to the water heater adequate? Check the condition of the burner.
63	Ignition Recycles	Clean or replace as needed. Check the burner flame and observe the
	Detected	microamp output on the run cycle. Replace burner if clogged with dirt and
		debris. Replace spark rod or flame sensor if damaged. Check to make sure
		vent terminals are clear of debris or snow and ice. Make sure the condensate
		drain flows freely.
64	Electronics Failure	Replace control board.
	High Water	Water temperature in tank has exceeded 200°F (93°C). Check tank sensor.
		Make sure sensor is fully inserted into the well (clip on sensor wire secures
65	Temperature (Over
		sensor in place). Check sensor reading. If not within specifications, replace
	200°F (93°C))
		sensor. If sensor and wire harnesses check O.K., replace control board.
