The unit was working fine and heating the water to appropriate temperature. I changed the water over the weekend and it heated the water to 120 degree then overheat light at the back turned ON. I tried to reset the unit by pressing the reset button but light comes back on as soon as I release the button. I lowered the thermostat to all the way down but the light (above the reset button) come back on as soon I turn the thermostat dial slightly..
What could be the problem ? Temp Thermostat or over-temp cut off (reset) switch assembly ? RE: Chattanooga - 2402 Hydrocollator M-2
