The valve opening temperature is stamped on the water inlet with thermostat.

(a) Immerse the water inlet with thermostat in water and gradually heat the water.

(b) Check the valve opening temperature.

Standard valve opening temperature:

80 to 84°C (176 to 183°F)

If the valve opening temperature is not within the specified range, replace the water inlet sub-assembly with thermostat.

Standard valve lift:

10 mm (0.394 in.) or more at 95°C (203°F)

If the valve lift is not as specified, replace the water inlet sub-assembly with thermostat.

If it is not fully closed, replace the water inlet sub-assembly with thermostat.
