Hoshizaki Flaker 5 Beeps: Water Valve Off Over 30 Minutes
Five beeps on a Hoshizaki F-1501M or F-2001M flaker mean the water valve has been off for more than 30 minutes since its last activation. The reset is manual: turn power off and on. The manual says to call for service and check the listed causes.
High: the machine stops and needs a manual reset, and the cause is usually in the refrigeration circuit.

What does Hoshizaki error code 5 beeps mean?
The control expects the water valve to open from time to time. If the valve has not been activated for more than 30 minutes, it treats the machine as stalled and sounds five beeps. The manual shows this alarm as a freeze-timer type alarm and lists the causes: a float switch stuck up, a water valve leaking by, a defective TXV, an LLV not opening, a low refrigerant charge, a headmaster not bypassing, and an inefficient compressor. These all describe a machine that is not freezing normally, so the valve is not called for. This is a manual reset alarm, so the machine stays off until the power is cycled. Cycling power only restarts the machine. If it returns, the cause is still present, and since most causes are in the refrigerant circuit, the manual's action is to call for service.
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
- Five beeps
- Machine stopped and not making ice
- Water not entering the reservoir
- Alarm returning after a power cycle
Possible causes
Listed in Hoshizaki's documentation
- Float switch stuck up
- WV leaking by
- TXV defective
- LLV not opening
- Low charge
- HM not bypassing
- Inefficient compressor
Other likely causes — what usually sits behind error code 5 beeps on this control. A technician confirms which one it is before any part is replaced.
- A float switch coated with mineral scale that sticks
- A water valve with scale that does not seat
- A low ambient or condenser problem that slows freezing
Safe checks before calling for service
- Turn the power off and on to restart, as the manual says.
- Watch whether water enters and ice begins to form.
- If five beeps come back, leave the machine and note when.
- Give the model and the time between the restart and the alarm to the technician.
How a technician diagnoses error code 5 beeps
- Confirm the 5-beep alarm and the 30-minute condition.
- Check the float switch for sticking and the water valve for leaking by.
- Check the TXV and LLV operation.
- Measure the refrigerant charge and headmaster action.
- Test the compressor, and replace the failed part after measurement.
- TXV, LLV, charge and headmaster checks are on the sealed refrigerant circuit.
- Float switch and valve tests involve live circuits and water.
- Seven causes share one alarm, so measurements decide the repair.
How error code 5 beeps differs from similar codes
5 beeps on this flaker table uses the freeze-timer-style cause list and needs a power cycle, while 3 and 4 beeps relate to the high-pressure switch.

How do I reset 5 beeps?
Turn the power off and on. It is a manual reset.
Why would the water valve not run?
The manual lists a stuck float switch and several refrigeration causes.
Is this the same as the KM freeze timer?
The cause list is similar, but this is the flaker alarm table and the reset is by power cycle.
