Bradford White Water Heater EF60T1253XA2

Service Procedure VII — Hot Surface Igniter Testing & Replacement

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

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?

Check the harness connection if voltage is absent

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

Replace the intake pressure switch if faulty

Refer to the vent safety switch, exhaust pressure switch, or blower testing procedures if the blower does not energize

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

Service Procedure V — Blower Testing & Replacement

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

Confirm the blower energizes when the thermostat calls for heat

Check for 120VAC across the terminal-block black and white wires

Check for 120VAC at the ignition module/control board and blower wiring

Repair or replace the harness or blower as indicated

Does the blower energize but seem weak?

Check amp draw on the black blower-motor lead (should read 0.6–3.0 amps)

Confirm the blower wheel is secure on the motor shaft

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.
