Hello, I recently went into service mode and seen this alert "front louvre blockage detected" no alerts on the main screen when not in service mode. The front louvre is currently closed. My question is could there be something actually abstructing its operation or could this mean it has failed? If this means it failed I will take it into service as i'm still under the 50k/4year. I just don't want to take it to service if I don't have to because they are not that close to me. thanks!
