Frequently Asked Questions

Q. "I just replaced the thermostat on my Ariston water heater. It is acting the same as the old one. As soon as I turn the unit on, it runs for a few minutes and shuts off. Is this new thermostat defective?"
A. Not necessarily. It may be working perfectly. If the heating element has become encrusted with scale or lime or if the anode rod is worn out and no longer working correctly, then either one of these conditions can cause the liner of the heater to over heat which in turn causes the thermostat to shut off. The thermostat is equipped with a thermal cut off switch. You will need to push the reset button to reset the thermostat after the problem has been corrected. Unplug the power cord to the water heater and remove the front cover. Press the reset button firmly with the tip of a ball point pin, extra small screwdriver or similar object. A click indicates the thermostat has been reset. Reconnect the power plug. Now check the operation of the thermostat. Turn the temperature dial from high to low. If the red light does not go off on the low setting, disconnect the power supply and replace the thermostat. If the red light does goes off on the low setting then set the dial to the desired setting and replace the cover plate. Note: If the heating element is in good condition and working correctly but the high limit needs to frequently be reset, then we suggest you call an electrical technician for further diagnosis.
