Troubleshooting Guides
Wine Storage Error Code Troubleshooting Guide Instructions
Error Codes indicate problems logged by specific components. If error codes are logged, they will appear before
temperature readings while in Diagnostic Mode and they can be toggled through with the temperature readings.
1. With the unit ON, initiate Diagnostic Mode by pressing and holding either COLDER key, then press the POWER
key, then release both keys.
2. Check for Error Codes on the display, making sure to toggle through all possible readings by pressing either
COLDER key. (See Error Code Table Below)
3. If Error Codes appear, reference the Error Code Troubleshooting Guide on the next page.
a. The left column of the Error Code Troubleshooting Guide lists the error codes.
b. The right column of the Error Code Troubleshooting Guide explains what tests and/or corrective actions to
perform.
NOTE: If error codes are observed, the SERVICE indicator will appear constant when Diagnostic Mode ends, indi-
cating error codes are logged. To clear this and the error codes from the software memory, the problem must be
corrected and the unit must be ON; then press and hold the bell key for fifteen (15) seconds. The control will emit a
quick "beep" when the SERVICE indicator and error codes are cleared.
