Error codeE0
ApplianceRefrigerator
Quick answer
E0 means door 1, the upper door, was open. It applies to U-Line refrigerators, wine cabinets, beverage centers and clear ice machines.
Model compatibility: U-Line reuses codes across series and model years, so E0 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Door 1 (upper) open, logged in the error log.
E0 is the code for door 1, the upper door, being open. It appears on U-Line refrigerators, wine cabinets and beverage centers in the UHRE, UHWC, UHBD, UHRI and UHRF lines (the 515 to 524 range), and on the UHCP115, UACP115 and URCC115 clear ice machines. It is a current-generation code.
What you see and hear
Every error is stored in memory, but the door error is the only one shown on the display, and it comes with an audible signal. The error log scrolls the stored errors in the order they occurred.
What to check
Make sure the upper door is closed completely. On two-door models the lower door has its own code, E9, so E0 points to the top one. If E0 shows with the door shut, call for service.

E10: the top drawer open for too long on older Echelon drawer models.
E1: thermistor 1 open, the next entry in the same log.

Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
