The valve opening temperature is inscribed on the thermostat.

  1. Immerse the thermostat in the water, then heat the water gradually.

  1. Check the valve opening temperature of the thermostat.

    Standard valve opening temperature:
    80 to 84°C (176 to 183°F)
    If the valve opening temperature is not as specified, replace the water inlet sub-assembly with thermostat.
