Bradford White Water Heater EF60T150E3N2

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

Reinstall the collector insulation and control panel

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

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

Reinstall the combustion system

Check several ignitions to confirm the burner lights smoothly

Service Procedure VIII — Flame Sensor Testing & Replacement

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

Check for a minimum of 1 microamp during the 1.5-second flame-proving period

Is the flame-sensing circuit okay?

Check for the expected 24VAC at the ignition module/control board flame-establishing terminals

Is 24VAC present at the ignition module/control board flame-establishing terminals?

Call technical support if 24VAC is absent

With the sensor disconnected, check for continuity to ground

Replace the sensor and/or wire lead if continuity to ground is present

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 V — Blower Testing & Replacement

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

Is the blower wheel secure on the motor shaft?

Replace the blower if draw is out of range or the wheel is loose

Confirm safety circuits are in their normal position
