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

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.
(c) Check the valve lift.
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.
(d) Check that the valve is fully closed when the water inlet with thermostat is at a low temperature (below
77°C (171°F)).
If it is not fully closed, replace the water inlet sub-assembly with thermostat.
