What does c2 mean on a Hoshizaki DCM-60KE / DCM-120KE cubelet dispenser?
Short answer: Abnormal high-side pressure caution. If your Hoshizaki DCM-60KE / DCM-120KE cubelet dispenser is showing c2, the controller has logged a specific, documented condition. This page covers what it means, what causes it, what you can safely fix yourself, and when — and why — it takes a technician.
What exactly is the machine telling you?
The condenser thermistor read above its set point for 5 seconds — the condenser is running too hot. The icemaking lamp blinks and the unit stops, auto-resetting when the condenser cools back below the set point.
Which machines show this?
the DCM-60KE and DCM-120KE are Hoshizaki cubelet ice dispensers with a digital display — unlike the beep-only machines, these show actual codes, in two tiers that matter. Lowercase c-codes are cautions: the machine pauses or adjusts and usually resets itself automatically. Uppercase E-codes are interlock errors: the machine has stopped, dispensing is disabled, and most require a power-off/power-on reset after the cause is fixed. The tiers are connected — cautions escalate into errors when they repeat (two c8 low-production cautions become an E1 lockout; five c2 pressure cautions become an E4). So a caution code is the cheap moment to act: it's the machine telling you what the lockout will be.
What causes it?
- The condenser running hot: dirty coil, dirty filter, blocked clearance
- Poor ventilation or a hot room
- Early fan motor or refrigeration problems
Can you fix it yourself?
Yes, and now is the cheap moment: clean the filter and condenser, restore ventilation, let it cool and auto-reset. c2 is the warning; E4 is the lockout it becomes at five-in-an-hour.
Step by step — what to try, in order:
- Clean the air filter and condenser
- Improve ventilation and clearance around the unit
- Let it cool and auto-reset, then monitor
When do you need a technician — and why?
Recurring c2 after a real cleaning points at the fan motor or refrigeration circuit. Catching it at the caution stage — before the E4 lockout — is the difference between a scheduled visit and an emergency one.
If it does come to a service call and you're in Nashville, TN or Birmingham, AL, we maintain independently compiled lists of local companies that service commercial ice machines — real businesses with verified contact information, none of whom paid to be listed.

When does c2 on a Hoshizaki DCM-60KE / DCM-120KE cubelet dispenser need a technician?
Recurring c2 after a real cleaning points at the fan motor or refrigeration circuit. Catching it at the caution stage — before the E4 lockout — is the difference between a scheduled visit and an emergency one. If c2 keeps recurring (5 in an hour escalates to an E4 lockout), have a technician check the fan motor and refrigeration circuit.
