Bradford White Water Heater EF60T1503XA2

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 the vent safety switch, exhaust pressure switch, or blower testing procedures if the 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

Service Procedures VI — Exhaust Pressure Switch / Blocked Vent Pressure Switch Testing

Does the purge LED or error code clear within 5 minutes?

Check exhaust collector pressure at the pressure tap with a manometer

Inspect the combustion system area and control panel

Exhaust/Blocked Vent Pressure Switch Replacement

Slide back the rubber escutcheon and remove the service panel access cover

Disconnect the silicone tubing and wire leads from the pressure switch

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.?

Adjust the spark rod if the gap is out of range

Support the spark rod near the ceramic insulator with pliers

Bend the end near the burner tube with needle-nose pliers

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

Reinstall the combustion system

Service Procedure VII — Hot Surface Igniter Testing & Replacement

Be aware of 120-volt potential exposure and handle the igniter with caution as it may be too hot.

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)

Service Procedure XIV — Anode Inspection and Replacement

Turn off the water supply and drain the water heater.

Disassemble the heater per the Disassembly Procedure for Access to Anodes & Flue Baffles.

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

Visually inspect each anode rod for depletion or exposed steel core.

Apply thread sealing tape or compound and reinstall the anode rods.

Restore the water supply and check for leaks.

Reinstall the collector cover per the Collector Cover Installation Procedure.

Reinstall the collector insulation and control panel, reconnect the control panel wire harnesses, restore power, and verify proper operation.
