Bradford White Water Heater EF60T150E3NA2

Service Procedure III — Burner Tube Inspection & Replacement

Turn the main power switch off and unplug the water heater, then turn off the gas supply.

Remove the surround cover, then disconnect the gas connection, PVC venting, wire harness, and silicone tubing from the gas valve.

Disconnect the wire harness from the blower assembly.

Remove the two screws holding the hot surface igniter and flame sensor and carefully remove them (for Direct Spark Ignition models, remove the spark rod bracket screws and spark rod instead).

Remove the four nuts holding the burner transition, lift the blower/gas valve/transition assembly off, and set the gasket aside.

Remove the burner tube from the burner mounting insert.

Service Procedure I — Thermostat Circuit Testing

Check error codes and conditions

Unplug electrical power to the water heater

Check continuity of the wire harness to the sensor

Check sensor resistance against the temperature/resistance table

Restore power and run the heater through a heating cycle

Error Code 65 (High Water Temperature)

Turn power off and draw water to cool the tank below 120°F

Check sensor and wire conditions

Service Procedure XIV — Anode Inspection and Replacement

Turn off the water supply and drain the water heater

Disassemble the heater for access to anodes and flue baffles

Locate and remove the anode rods using a 1-1/16 in. hex socket

Visually inspect each anode rod for depletion

Apply thread sealing tape or compound and reinstall the anode rods

Restore the water supply and check for leaks

Service Procedure II — Combustion System Testing

Observe burner operation through the sight glass

Verify minimum gas supply piping size

Confirm static inlet gas pressure is stable between 7 and 14 in. W.C.

For models with Hot Surface Ignition

Confirm the inlet gas pressure does not drop more than 2 in. W.C. during ignition

Check that the igniter glows through the sight glass during warm-up

Check for 120VAC at the ignition-module igniter terminals

Check igniter cold resistance is under 150 ohms

Service Procedure XII — Intake Pressure Testing (models prior to serial "CF" only)

Check continuity through the normally closed intake pressure switch if the blower does not energize

Refer to vent safety switch, exhaust pressure switch, or blower testing procedures if intake pressure switch is not faulty

Check continuity through the switch if the purge LED does not illuminate within the expected time

Confirm the inlet tube pressure tap reads at least -1.2 in. W.C. using a manometer

Remove the hose from the intake pressure switch and restart the heater to see if the purge LED illuminates

Isolate the heater from the intake vent system and restart again to isolate a switch versus vent-system fault

Check whether the intake vent system is obstructed and clear any obstruction found

Call technical support if no cause is found
