SERVICE (cont.)
ELECTRONIC CONTROL ASSEMBLY
Location:
The electronic control assembly (1) is located
inside the lower left front on the component bracket of
the brewer. Access will also be needed to the tempera-
ture sensor (8), liquid level probe (7) located on the
tank lid and to the triac assembly (17) located beneath
the tank.
General:
This system controls the liquid level and water
temperature of the brewer. These two functions act
independently of each other and should be tested
separately.
