Hoshizaki Flaker 2 Beeps: Control Switch Left in Drain
Two beeps on a Hoshizaki F-1501M or F-2001M flaker mean the control switch has been left in the DRAIN position for longer than 15 minutes. Move the control switch to ICE. The alarm resets itself when you do.
Low: an operator reminder; moving the switch to ICE clears it.

What does Hoshizaki error code 2 beeps mean?
The control switch has positions for making ice and for draining the water system. DRAIN is meant for a short, deliberate use, such as emptying the reservoir for cleaning. If the switch stays in DRAIN for more than 15 minutes, the control sounds two beeps as a reminder that the machine is not making ice and the water system is open. This is not a failure of any part. The manual's action is to move the control switch to ICE, and the alarm resets automatically when the switch is moved. The most common situation is that a cleaning or service task was finished but the switch was never put back. If the alarm continues with the switch in ICE, the switch or its wiring should be checked, but the manual does not describe that case.
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.

Possible causes
Likely causes — what usually sits behind error code 2 beeps on this control. A technician confirms which one it is before any part is replaced.
- Control switch left in DRAIN longer than 15 minutes
- A switch bumped during cleaning
- A cleaning or service step finished without returning the switch
- A switch that does not stay in the ICE position
Safe checks before calling for service
- Look at the control switch and move it to ICE.
- Wait a moment for the alarm to clear and the machine to refill.
- Watch that the machine begins making ice again.
- If two beeps return with the switch in ICE, note it and call service.
How a technician diagnoses error code 2 beeps
- Confirm the 2-beep alarm and the switch position.
- Move the switch to ICE and confirm the alarm resets.
- Check that the switch holds its position.
- Test the switch contacts if the alarm continues in ICE.
- Confirm the machine returns to normal ice production.
- Switch contact tests are done with a meter in a live control circuit.
- The manual covers only the left-in-DRAIN case, so other causes need diagnosis.
- Draining and refilling with a bad switch can waste water.
How error code 2 beeps differs from similar codes
2 beeps on a flaker is the control switch in DRAIN; on KM cubers 2 beeps is the harvest backup timer.
