What 4 beeps
actually means.
The first two high-pressure trips in an hour give three beeps and reset themselves. A third trip in the same hour changes the alarm to four beeps and needs a manual reset. Hoshizaki recommends leaving the unit off until the cause is found, because repeated high pressure risks serious damage. Anything that keeps the condenser from shedding heat, such as a blocked air intake, can drive pressure up.

What to do when 4 beeps shows on the ice machineKind of codeCondenser and airflow
The machine could not shed its heat. An air filter packed with lint, a condenser coil furred with grease and dust, a fan motor that no longer spins, a machine pushed into a hot corner without its clearance, a water-cooled condenser whose regulating valve starves it, or a remote condenser on a roof blocked by leaves all show up here. Washing the air filter and freeing the space around the machine clears many cases; a fan motor or a valve means a visit.
Usually leads toIce machine condenser and fan repair
Air-cooled coils, fan motors and filters, water-cooled regulating valves and rooftop remote condensers, cleaned or repaired so the ice machine can shed its heat.

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.

What not to do
Four beeps are not a water shortage; that is one beep on a DCM. The KM cuber table does not use four beeps.

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.
