HEATING ELEMENTS
: The heater elements
are replaced when necessary by removing the
back panel after disconnecting all power to the
unit. Electrical connections to the elements are
disconnected from the contactor. Remove the
cotter pin or anti-vibration compound that
keeps the element in the tube and pull the
element out of the SS sheath enclosure in the
water tank. New elements should be handled
minimally to avoid rubbing off the white
powder coating. Simply press in as far as
possible and replace the friction pin if there is
one present. Reconnect the wires at the same
locations on the contactor.

Milk does not get to temperature but the
Heater is hot.
a.
There are two active heating
elements (the third one in the center
is a spare unless it is a 3 phase
application in Europe then all 3 are
used) and it is possible that only one
is operable. Check resistance on
each element with the power off to
determine if one needs replacing.
b.
Make certain that the agitator motor
is turning during the cycle. It should
be on during heating, timing, and
cooling cycles. Replace if it is not
working.
c.
Check the bottom of the milk tank
to make certain that it is being
cleaned properly after each use. If
there is milk build up or significant
sticking, the unit is not being
cleaned properly and heat transfer
will be decreased, but more
importantly, this is a prime
opportunity for pathogens to grow.
d.
Milk level is not high enough. The
thermocouple needs to be fully
covered in milk as it measures milk
temperature at the tip. Also, too
little milk will not allow optimal
stirring which will decrease heat
transfer and give false temperature
readings.
e.
Cold water is coming into the
system. If there is a leak in the
system, such as a leaking cold water
solenoid valve, the heater cannot
keep up and the milk will not heat
properly. Repair the leak or replace
the valve.
5.
Water is leaking out the bottom of the Unit
a.
Look under the machine on the
sloping back floor, right side as you
face the machine from the front.
There is a pressure relief valve
located here that will purge water if
the drain line becomes occluded or
pressures to the tank are too high.
Check that the line is not blocked or
kinked. See diagram below
