[d] FAULT DIAGNOSIS
Check the status of the Service Lamp on the Controller Board (LED-5, See “[c] SEQUENCE”)
by removing the Control Box Cover.
Lamp ON - Water Plate closed
This tends to indicate the Back-up Timer has stopped machine operation during the freeze
cycle. High ambient and water temperatures are an obvious cause. But check out each
component that could result in an extended freezing time (See guide below).
Lamp ON - Water Plate open
The Timer has stopped the machine because of an excessive defrost time. See the guide
below to check out the probable cause.
Lamp flashing ON/OF
If on the first cycle, check out the Cam operation and/or Toggle Switch. If the machine has
been in service for some time, the Controller Board may be at fault.
REMEMBER: Hoshizaki controllers are very reliable. They also control every component’s
operation. So if a component malfunctions, the controller will respond.
Do not replace controllers in an attempt to shorten the diagnostic process
and not before carefully checking the actual fault and possible cause.
When the icemaker stops, the Controller Board Interlock Indicator shows possible faults.
