Resetting

High Limit

Switch

Occasionally, the high temperature limit shut off device may trigger and shut the system down. This occurs when water temperature exceeds 190° F and shuts off power to the heating element. The shut off device may also trigger from a power outage or electrical storm.

To reach the thermostat:

1.Pry off the round cover plate (V Fig. 3/1) from its right hand edge (W Fig. 3/1) with a small flat-head screwdriver.

2.Remove the Phillips screw revealed beneath the round cover plate.

3.The cover (C Fig. 3/1) can now be removed by pulling out its left-hand edge. When reassembling, work in the opposite way being careful to insert the tongue of the cover into the slot.

4.Firmly press reset button (B Fig. 4). Reconnect power.

5.IMPORTANT: Check the operation of the thermostat, turn temperature dial from high to low, if the red light does not go off on low setting, turn off power supply and call a service person to replace the thermostat.

6.If the system works, place dial setting to desired setting. Note: a lower setting is more economical and reduces the risk of scalding. Replace cover plate.

CAUTION: Call a technician if the high limit needs to be reset frequently.

Troubleshooting

Water does not get hot

1.Make sure the power supply is on and working.

2.If light does not come on, check that the reset button is pushed in; follow steps from previous section.

3.If the indicator light works properly but temperature does not get hot a tap, test for a plumbing crossover; shut off cold supply to heater and open hot water tap. There should be no water flowing. Any continued flow indicates a crossover which will effect the temperature and will need to be corrected.

4.Replace heating element (see previous section on changing the heating element).

1.Smelly water could be due to an unusual reaction between local water and the heater’s anode rod. Check anode rod (see section on changing the anode rod).

1.Remove cover plate and turn the temperature selector dial (D Fig. 4) counter clockwise to lower temperature. If temperature never lowers then replace thermostat. (see section on changing the thermostat).
