Current production water heaters with the 110 VAC heating option use a screw-in heating element, a separate pre-set thermostat and a separate ECO.

The screw-in heating element is rated at 1400 watts just like the bolt-on element. It is an incalloy element and can be run for a limited amount of time in a dry tank without shorting out.

CAUTION: If the heating element is allowed to run with a dry tank, allow the tank to cool down for 2-3 hours before adding water. Adding water before the tank cools sufficiently could collapse the tank.

The thermostat and ECO are pre-set surface-mounted discs. The thermostat is set at 140° F and is the same thermostat used on the gas side of the electronic ignition water heaters. The ECO is a backup thermostat and will trip if the thermostat fails and the water temperature exceeds 170° F.

When the 110VAC portion of the water heater is not heating water, the following diagnostic steps and repairs should be investigated:

Turn POWER OFF to the appliance before removing junction box cover.

Perform the following steps with POWER ON to water heater.

1.Verify switch is in ON position.

2.Insure there is 110VAC to the unit (measure voltage across the black and white lead to the appliance with POWER ON). If none, trace wiring back and make appropriate wire repair.

Perform the following steps with POWER OFF to water heater.

3. Manual reset ECO high limit switch-A should be depressed. Check for continuity between

TERMINAL B and TERMINAL C of ECO.

4.Check for continuity between TERMINAL D and TERMINAL E of thermostat. If there is none, replace thermostat.

5.If water is insufficiently hot, insure thermostat is flush with tank.

6.Verify a good wire connection between ECO TERMINAL-C and heating element TERMINAL-F. Correct if necessary.

7.Check for continuity between heating element TERMINAL-F and TERMINAL-G. If none, element is bad and should be replaced. Do not over-tighten self- tapping screws when installing new element.

8.There should NOT BE CONTINUITY between element screw-G and flange of element. If there is, element has shorted. Element should be replaced.

9.Verify ground connection.

NOTE: Heating element can be operated on an empty tank for a limited period of time before it self destructs.
