Safety Overflow Switch

Location:
The safety overflow switch is located inside the rear of
the dispenser inside the copper overflow cup.
For testing or removal of the safety overflow switch,
access may also be needed by removing the two screws
attaching the electronic control assembly to its mount-
ing bracket.

Test Procedure:
1.

Once voltage is verified at the power source, check
for continuity across the safety overflow switch
red wires only until the plastic float is raised and
check that continuity returns when the plastic float
is again lowered.

If continuity is present as described, reconnect each
of the red wires to the black wires, the safety overflow
switch is operating properly.
If continuity is not present as described, replace the
safety overflow switch.
