Bradford White Water Heater EF60T199E3N2

Service Procedure III — Burner Tube Inspection & Replacement

Take precautions to avoid injury as heater components can be hot during this procedure

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 XIII — Vent Safety Switch Testing and Replacement

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.

Turn the main power switch off, slide back the rubber escutcheon, and remove the service panel access cover.

Disconnect the wire leads, remove the two mounting screws and nuts, and remove the switch.

Install the new switch, reconnect the wire leads (interchangeable), restore power, confirm proper operation, and reinstall the cover and escutcheon.

Service Procedure VII — Hot Surface Igniter Testing & Replacement

Be aware of 120-volt potential exposure

Ensure the igniter is cool before handling

Measure 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

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

Check if the blower energizes but seems weak

Measure amp draw on the black blower-motor lead

Confirm the blower wheel is secure on the motor shaft

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
