Hoshizaki Flaker 9 Beeps: Bin Control 2 Circuit
Nine beeps on a Hoshizaki F-1501M or F-2001M flaker mean an open circuit at control board K8, pins 3 and 4 (mechanical Bin Control 2). It is not used on DCM models. Check the bin control wiring and turn power off and on to reset.
Low: an open bin control circuit stops the machine, but the cause is typically wiring or a setting.

What does Hoshizaki error code 9 beeps mean?
The mechanical bin control signals when the ice bin is full. On this board it is connected at K8, pins 3 and 4. If that circuit is open, the control sounds nine beeps. This alarm is manual reset, so power must be turned off and on after the cause is dealt with. The manual's action is to check the bin control wiring and the S2 dip switch setting. S2 dip switch 7 must be ON for modular flakers and cubelet models, and OFF for DCM and self-contained models. The alarm is not used on DCM models. A wrong dip switch setting or a loose or broken bin control wire is the usual cause. The manual does not list further causes, so a missing bin control or a disconnected plug are the kinds of things a technician looks for.
Affected models and control systems
F-1501M and F-2001M J-board modular flakers; the same alarm table in the manual is marked for DCM models where it applies.
Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.
What you may notice
- Nine beeps
- Machine stopped
- Bin control plug or wire that looks disconnected
- Alarm returning after a power cycle
Possible causes
Likely causes — what usually sits behind error code 9 beeps on this control. A technician confirms which one it is before any part is replaced.
- Open circuit at control board K8 (#3 and #4)
- A bin control wire pulled loose when the bin was cleaned
- A bin control plug that has corroded or backed out
- A dip switch S2 number 7 set for a different model type
Safe checks before calling for service
- Turn the power off and on once to see whether nine beeps returns.
- Look for a bin control wire or plug that has come loose, without opening panels.
- Do not change dip switches yourself.
- Note the model and when the alarm began, and call service.
How a technician diagnoses error code 9 beeps
- Confirm the 9-beep alarm and that the model is not a DCM.
- Check the bin control wiring and plug at K8, pins 3 and 4.
- Check continuity of the bin control circuit.
- Confirm S2 dip switch 7 is ON for modular flakers and cubelet models.
- Reset by power cycling and confirm the alarm stays off.
- The control board is live and dip switch changes must follow the manual for the model.
- Continuity tests require a meter and access to the board.
- A wrong dip switch setting can make a healthy machine alarm.
How error code 9 beeps differs from similar codes
9 beeps is the mechanical Bin Control 2 circuit and is not used on DCM models, where S2 dip switch 7 is OFF.

How do I reset it?
Turn the power off and on after fixing the cause, since it is a manual reset.
Does this apply to DCM?
No, the manual says it is not used on DCM models.
