BC0530 Service Manual
CODE: FAULT CODE INDICATES:
6 (Rev 1.1/1.2)
Water fill exceeds 5 min.
(Rev1.3)
Water fill exceeds 3 min,
then the Valve closes &
waits 10 min, as Code 60
LED flashes. Valve then
opens & tries again. This
routine repeats 3X & results
in a solid Code 60, if the fill
is not completed on the third
try.
7 (Rev 1.1/1.2)
Evaporator Temperature
<31F, during water fill only.
(System opens Hot Gas
Valve to compensate, until
an Evaporator temp of about
38F is reached. This temp
range is adjustable from
about 35-46F).
(Rev 1.3)
Both Arm-Up/Arm-Down
(Cam) Switches Closed, (un-
actuated) at the same time
(Not allowed).
Code 7 is actuated if the arm
up light and the arm down
light both illuminate at the
same time.
POSSIBLE CAUSE:
Water supply off or major leak in
the water tank, or water lines.
External water filter plugged.
Water solenoid valve inoperative.
Upper (short) Probe, in the Water-
Level Probe Assy, may have a
loose wire connection (open).
Common (longest) Probe, in the
Water-Level Probe Assy, may have
a loose connection (open)
Controller is bad.
(Rev 1.1/1.2)
This is not necessarily a fault
condition, but could indicate that
the incoming water temp is very
cold, which can slow down ice
production, as the Hot Gas Valve
continuously reopens to warm the
Evaporator to >38F.
(Rev 1.3)
Switches are loose.
Switches are mis-wired.
Switch Bracket bent & switches not
in position.
Switch Cams loose and/or in the
wrong position.
Arms-Up Switch stuck closed –
Plate stays down.
Arms-Down Switch stuck closed –
Plate stays up.

SOLUTION:
Turn on water supply or check for
leaks.
Replace, bypass or eliminate
external water filter.
Place in Wash Mode and pull down
on water plate, to lower it. On the
return up, water valve will energize
to fill, until the short probe is
reached. If water solenoid valve has
power & water, but does not open,
replace the valve.
Verify wire connection is securely
crimped on top of probe & back to
Controller.
Verify wire connection is securely
crimped on top of probe & back to
Controller.
Replace Controller.
No action required. (Increase
incoming water temp to >45F for
best results)
Tighten switches.
Wiring should be to the Common
& Normally Closed (NC) positions,
with black wire to the bottom-front
NC terminal and red wire to the
bottom-rear NC terminal. White
wires should go to the Common
terminals on top.
Straighten bracket.
Cam flats should be almost opposite
each other. See Water Plate Up/
Down adjustment, page 41 of
Service Manual.
Replace stuck/shorted Arms-Up
Switch or check solutions 2-5
above.
Replace stuck/shorted Arms-Down
Switch or check solutions 2-5
