First, reset your circuit breaker and try turning on your central unit again. Second, check if there are any faulty devices connected to your meter.
If the problem persists despite these checks, please contact us at 05.34.27.08.92. It could be an issue with the motor of your central unit.
If your central unit is still under warranty, we can arrange a return procedure. If not, please contact us so that we can work together to find a solution to your problem.
