Powered Anode Replacement
Water heater components may be HOT when performing the following steps in
this procedure. Take necessary precaution to prevent personal injury.
The powered anode control module is located on the vertical side of the control panel inside the surround
panel. The control has a LED indicator light to show the status of operation. When the tank is filled with water
and the power supply is on the water heater, the light should have a steady green glow to indicate that
protection current is flowing and operating normally. If the indicator light is not glowing, the power supply to the
water heater or powered anode system is disconnected.
1. Check the power supply or wire connections to the powered anode control.
2. Indicator light diagnostic codes:
a. If the control is flashing red, then there is a malfunction with the powered anode system.
Make sure there are no bare spots in the wire insulation to the powered anode rods.
3. Check all electrical connections. The powered anode rods are insulated from the water heater tank in
the bushing.
a. With an ohmmeter, check continuity between the powered anode terminal and the bushing.
There should not be continuity. If there is continuity, replace the powered anode assembly.
