My Mix 60 Plus motor will not start, or it does not stop when I lift the grid. What do I check?

Unplug the mixer first. For a motor that will not start, the manual lists these causes: no power on the cable, a plug not fully inserted, a faulty cable to the electrical panel, a loose wire in the panel or at the motor terminal board, a faulty main switch, or a tripped residual current breaker. Reset the breaker; if it will not reset, have a qualified electrician check the electrical system. If the motor does not stop when you lift the safety grid, the limit switch is faulty and needs replacing. If the motor starts with difficulty, the mix is too stiff: reduce the quantity or thin it and try again.
