Error codeMAINTENAINCE / MAINTENANCE
ApplianceBlast Chiller
A reminder, not a breakdown
MAINTENAINCE is spelled that way in the alarm list, and some people write MAINTENANCE. The chiller is asking for its regular service inspection and preventive maintenance, and the manual’s wording is simply to call service.

Blast chiller maintenance service in San Francisco
To book the inspection for a San Francisco or Bay Area chiller, call (415) 329-7078. Mention the reminder on the screen and give the model number. See also U-Line freezer repair.
Model compatibility: U-Line reuses codes across series and model years, so MAINTENAINCE / MAINTENANCE may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
