Bradford White Water Heater EF60T1503X2

Service Procedure XIII — Vent Safety Switch Testing and Replacement

120-volt potential exposure; use caution making voltage checks.

Confirm the exhaust collector compartment is not overheating (350°F) before resetting the switch; call technical support if there is evidence of overheating.

Locate the harness connection and check continuity through the grey lead wires of the heater-side harness; call technical support if there is none.

If continuity is present, depress the reset button on the high-limit switch and check for continuity across it, replacing the vent safety switch if there is none.

Reset the heater and observe a heating cycle to confirm the switch does not reopen before 350°F is reached; replace the switch if it opens prematurely, and do not operate the heater if temperature exceeds 350°F without contacting technical support.

Service Procedure VII — Hot Surface Igniter Testing & Replacement

WARNING — 120-volt potential exposure; the igniter may be too hot to handle, so use caution.

Igniter's cold resistance check

Check the igniter's cold resistance

Is the igniter's cold resistance under 150 ohms?

Replace the hot surface igniter if resistance is not under 150 ohms

Check for 120VAC across the ignition module's igniter terminals during the warm-up period (igniter LED lit)

Is voltage present across the ignition module's igniter terminals?

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 IX — Spark Rod Gap Inspection and Adjustment (Direct Spark Ignition models)

Remove the combustion system per the Combustion System Removal procedure

Measure the spark gap between the spark rod and burner tube

Is the spark gap within the acceptable range of 3/16 in. to 1/4 in.?

Carefully bend the spark rod if the gap is out of range

Re-measure to confirm the gap is within 3/16 in. to 1/4 in. after bending

Reinstall the combustion system

Check several ignitions to confirm the burner lights smoothly
