A soft lock can also occur any time during operation
when the hopper or freezing cylinder temperature
rises above 59°F (15°C), or the temperature rises
and remains above 41°F(5°C) for more than four
hours. If a PRODUCT OVER TEMPERATURE
condition occurs during operation, the following
screen will appear. (See Figure 18.)

When one of these messages appears, automatic
freezer operation cannot take place until the freezer
is disassembled and brush cleaned, or has
completed a heat treatment cycle. Select the HEAT
symbol
to start a heat cycle, or select the WASH
symbol
to disassemble and brush clean the
machine.
Once the freezer is unlocked by starting a heat
treatment cycle the HEAT symbol
will illuminate
and the following message will be displayed on the
screen. (See Figure 19.)

If the WASH symbol
is selected to clear the
lockout by brush cleaning the machine, the
FREEZER LOCKED message will remain on the
display until the brush clean requirements are
fulfilled. The freezer must be disassembled in order
to activate the five minute timer on the display
screen. Once the timer counts down to zero, the
lockout is cleared. (See Figure 20.)

seconds, and then return the power switch to the
ON position. The original message with the reason
for the soft lock will be displayed. (See Figure 21.)
