What 8 beeps
actually means.
In a DCM, the gear motor turns the auger that pushes cubelet ice out of the evaporator. The compressor may run only when the gear motor circuit proves it is running, through the compressor control relay. If that relay does not close, the board stops the unit with eight beeps. A blown gear motor fuse or a tripped motor protector is the usual reason, and repeat trips point to a mechanical problem.

What to do when 8 beeps shows on the ice machineKind of codeControl board and power
The board lost track of itself or of its power: a voltage too low or too high at startup, a relay that no longer closes, a keypad or display that stays dark, or a memory error after a surge. Switching off at the machine's own switch for a minute clears a passing glitch. A code that returns, a breaker that trips, or any hot or burning smell means the power stays off and the board, the wiring and the relays are left to a technician.

The controller, its display, the sensors it reads and their wiring, tested when a code, a blinking light or a dead machine points there.
Shows up asIce Machine Error Code or Flashing Light: What It Is Telling You
An ice machine error code may show as a number on a small display, a pattern of blinking lights on the control board, a colored light on the front, or a machine that stops with one indicator flashing.

On a Hoshizaki ice machine, the technician notes every alarm signal and checks the water and condenser before pricing any part.

DCM cubelet icemaker/dispensers (DCM-300, 500, 751, 752) repeat the beeps every five seconds and also light an orange ALARM LED; their beep list differs from the KM list.
Before you book,
in this order.
Each step comes from Hoshizaki's own guidance for 8 beeps on its ice machines. Follow it to the end: the last card says whether this is a visit.
Switch the unit off and let it sit so a tripped motor protector can cool.
Turn it back on once; Hoshizaki gives power off and on as the reset.
If eight beeps return, book a visit; repeated trips point to the gear motor or auger.

What not to do
Eight beeps are not a voltage alarm; those are six and seven. The KM cuber table does not use eight beeps.

Every code on this site is taken from the manufacturer's documentation, never from a forum or a parts listing. DCM cubelet icemaker/dispensers (DCM-300, 500, 751, 752) repeat the beeps every five seconds and also light an orange ALARM LED; their beep list differs from the KM list.

A booking with a code goes further when it carries the light or code copied as it appeared, the model and serial off the data plate, and a word on whether cubes still fall into the bin. With those three in hand, our office can match the probable part to your machine the same afternoon.
