 See larger image Read updated manual when doing repair on Energy Smart New technology means design changes read: new control board for 6-year old tank Control board Photo shows electronic control board. Do not operate water heater if control board, elements or heat sensors get wet. All electric water heaters carry risk of electric shock after flood or when tank is leaking. Turn off circuit breaker and use caution. 240V power connects to red and black wires at control box. 30 amp, 240V breaker and 10 gauge wire required for connection. Green ground screw sits out of sight in this photo and threads into metal top of tank. Blue and Yellow wires send power to upper element. Blue and Orange wires send power to lower element. Each element is 4500 Watts, and overall tank wattage is 4500 Watts. Tank operates in typical 'non-simultaneous' manner where both elements are not 'on' at same time. One element is 'on' or the other element is 'on,' or both elements are off. Small black and red wires located on bottom left of control board connect to temperature sensors located above each element. Temperature information is processed by control software that turns heating elements on and off. |

Do not lean into or touch anything made of metal. Stand on dry boards. Tape tester leads to wood sticks Set multimeter to read volts AC  |
  Upper element and foam insulation Upper element/ Yellow and Blue wires After removing two screws holding access door, and pulling back tight-fitting 2" foam insulation and plastic cover, the upper element is visible. Resource: Energy Smart Parts list Operating water heater "without insulation and access doors will result in much higher water temperatures than desired set point." See Whirlpool product manual for more maintenance/ installation information. Resource: How to test elements |
  Lower element Lower element/ Orange and Blue wires Insulation and covers must be in place for thermostat to operate correctly. Read manual pg 9 Lower element is covered by dense 2" foam insulation and plastic cover. Adding water heater insulating blanket to Energy Smart electric water heater could void warranty. Do not cover control box or TP valve with insulation. Does water heater need more insulation? Tape thermometer to water heater, cover thermometer with insulation, after 20 minutes, remove insulation & compare before and after thermometer reading. Resource: How to test elements |

 Upper and lower elements can be replaced You can use ordinary foldback element for energy smart. Manual says "make sure replacement element has correct voltage and wattage rating" Whirlpool Energy Smart elements for 40 gallon are 240 Volts and 4500 Watts. Element information printed on end of each element. Typical replacement elements available at hardware and home center. Temperature Sensor can be ordered as repair part. Phone call to Whirlpool parts sales was handled in United States, and sales lady said she replaced sensor during training, and added that she is 'not mechanical at all.' TP valve is located on side of tank. Additional 3/4 plug on top of tank for relocation of TP. Check your manual since models vary. Plug on top of tank allows easy adaptation when replacing water heater. |

 ThermistorFigure 9: element and THERMISTER or heat /temperature sensor Repair parts: Non-standard parts cause delays and expense for customer. You might not have hot water until part arrives. Off-the-shelf thermostat for regular water heater is sold at local hardware. Read updated manual when ordering parts and doing repair on Energy Smart. New technology means frequent design change, and possible lack of parts for older designs |

 Energy Smart has dry fire protection Dry Fire prevention is not 100% sure. |
Dry fire prevention All designs of Energy Smart have dry fire detection. This will help prevent dry-fire incident, but not foolproof. If water is not covering elements, then elements will dry-fire and instantly burn out. Water heater must be full of water before electricity is turned ON, or upper element instantly burns out. If element is 'dry' and electricity is turned ON, then element burns out. Prevent dry fire: Fill tank completely with water, until water is coming out of tub spout, then open Tp valve to release last of air from inside tank, and lastly, turn power ON.

Whirlpool manual suggests mixing
valve Why? The newest energy smart has 5500 watt elements for higher first hour delivery. First hour means the amount of usable hot water from a single continuous draw. You can further increase first hour delivery by setting the thermostat higher. The risk of high temperature water coming from tank can be solved by using a mixing valve. For example the tank is set to 145°F, but mixing valve is set to 120°F... ... then the mixing valve adds cold water to the line... ... and maximum water temperature at any tap is safe 120°F This means more hot water is stored inside tank so you get higher first hour ... ... without risk of scald.

 Heat trap washer |
 Di-electric nipples |
Option ... remove heat traps to
prevent
water pressure issues Whirlpool energy smart has rubber heat-trap nipples located under each of the connection nipples. This type washer is usually not a problem, but some can clog and cause low water pressure. Resource: Low water pressure You can cut out center of this type washer by pushing washer over a sharpie marker and then use knife to cut away flaps. Di-electric nipples will keep water heater from deteriorating because of stray current corrosion.
