4. Screw in the new anode and secure with the retaining nut.
5. Follow instructions for replacing the element in “ELEMENT CLEANING/REPLACEMENT.”
HIGH LIMIT SWITCH REMOVAL AND REPLACEMENT
1. Turn off and unplug the heater from the electrical outlet.
2. Remove the front panel; see the “REMOVING THE FRONT PANEL” section in this manual. Remove the
insulation pad. Remove personnel barrier.
3. Remove the four wires connected to the switch, taking care to note the original placement of each wire.
4. Using a 7mm wrench, remove the nuts securing the high limit switch to the rank enough to rotate the switch
90° counterclockwise and slide it out from beneath the bracket. It is not necessary to remove the nuts
completely.
5. Place the new switch beneath the bracket and rotate it 90° clockwise.

SERVICE
If a condition persists or you are uncertain about the operation of the water heater contact a service agency.
Use this guide to check a “Leaking” water heater. Many suspected “Leakers” are not leaking tanks. Often the
source of the water can be found and corrected.
If you are not thoroughly familiar with your water heater and safety practices, contact a qualified installer to
check the water heater.
LEAKAGE CHECKPOINTS
Read this manual first. Make sure the electrical power supply has been turned “OFF” before checking the tank
for leakage.
• Condensation and dripping may be seen on pipes if the water temperature is low in humid weather or pipe
connections may be leaking.
• Small amounts of water from temperature-pressure relief valve may be due to thermal expansion or high
water pressure in your area. If the valve is not piped to an open drain the released water could be mistaken
for a leaking heater, see “Thermal Expansion” section.
• The temperature-pressure relief valve may be leaking at the tank fitting.
• Water on the side of the tank may be condensation due to the panel or insulation not being in place.
• Water in the water heater bottom or on the floor may be from condensation, loose connections, or the relief
valve. DO NOT replace the water heater until a full inspection of all possible water sources is made and
necessary corrective steps taken.
Leakage from other appliances, water lines, or ground seepage should also be checked.
