13. Control Board Replacement
The dip switches should be adjusted to the factory default settings as outlined in this
manual.
1) “OFF”
In the “OFF” position, no power is supplied to
the unit. However, to avoid any possible risk of
electrical shock, disconnect the power before
servicing.
2) “ICE”
This position applies power to the unit causing
the automatic icemaking process to begin.
Refer to “
II. Sequence of Operation and
Service Diagnosis” for further details.
3) “WASH”
When the control switch is placed in the “WASH”
position, power is supplied to the pump motor
and cleaning valve. This allows cleaning and/
or sanitizing solutions (see “
V. Maintenance”)
to circulate throughout the water system and
down the inside and outside of the evaporator
plates.
