I am having trouble with my 8’ blade. I’ve had it for almost 3 years.

When I turn on the battery, the light comes on as it should. When I try to go up or down the light flash as I hit the buttons but the motor does not make any noise. The tank is half full of hydraulic fluid.

I’ve already tried the diagnosis on the app.

Has anyone had this problem before or have an idea what the solution might be?
