What usually goes wrong

  • It will not power up, or it blows fuses.
  • The pump will not spin up, or its speed will not hold.
  • The pump turns the wrong way.
  • No communication, or a bad relay or connector.
  • An error code on the display.
  • A blinking failure light.

Behind most of these sits the power supply, the motor drive circuit, or the control and communication circuits, and on maglev units the levitation circuit.
