Wine Storage Error Code Troubleshooting Guide Instructions
Error Codes indicate problems registered by specific components. If error codes are registered, they will appear
before temperature readings while in Diagnostic Mode.
1. Initiate Diagnostic Mode by pressing and holding either COLDER key, and 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 or either WARMER key.
3. If Error Codes appear are displayed, follow the Error Code Troubleshooting Guide on 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 short "beep" when the SERVICE indicator and error codes are cleared.
