movement: In the back of the
Dispenser.
Verify magnet block is secure and no foreign object is attached to
the magnet.
Check behind the accumulator mechanism for any foreign object
which may be restricting movement of the assembly.
Calibration has been changed
or lost.
Reset Dispenser parameters (defaults) using the
Parameter
function in the

are operating.
Error 6
(Cooling Failed)
(high pressure error)
Error must be reset using
the Held Errors parameter in
the Clear Functions section
of the Service Menu.
(See reset instructions on
page 222
.)
Dirty or clogged condenser
and/or filter.
Clean the condenser and filter. Use
Held Errors
parameter in
the
Clear Functions
section of the Service menu to clear the
error.
High ambient temperature.
Temperatures should be kept below 90°F. Verify A/C is
functioning.
Power outage.
A power outage disrupts the feedback loop, causing the error.
Faulty power cord.
A faulty power cord may cause a disruption in the feedback loop.
Replace a cut or damaged power cord
Faulty feedback or refrigeration
relay.
An intermittent or unexplained error 6 may be caused by a faulty
refrigeration (SW2) or feedback relay (SW3).
This can be difficult to diagnose. Verify the refrigeration relay is
receiving a signal from the controller. Replace both if suspect.
Faulty condenser fan.
The condenser fan and compressor should be running at the
same time. If the compressor is running but the condenser fan is
not, the condenser fan motor is faulty. Replace.
Faulty compressor or
compressor start components.
Verify if compressor will run if power is applied to it. Check start
components and wiring.
Faulty controller (rare).
Verify that the controller is sending voltage to the refrigeration
relay (SW2). The Error 6 will need to be reset using the
Held
Errors
parameter in the
Clear Functions
section of the Service
menu for the controller to send voltage to the relay. There is a
short cycle delay of about 2 minutes after the Dispenser is
powered on.
