Procedure hot water valve
Although the twist-knob on the water valve has no function, the interior parts of the
valve get warm and must be serviced. The hot water valve contains fewer parts (see
figure 20, compare to figure 19). Since there is no plunger, it is not necessary to remove
the valve from the machine.
