Explanation

The Vacuum Pressure alarm indicates that the machine is attempting to run a program cycle and the sensor signal for adequate vacuum is not present.

Potential causes:

  1. This is common when surfacing spoil board as the lack of material greatly reduces vacuum pressure. There is a bypass button for this scenario. (IMG 1)

  2. Leaking: Gasket issues, insufficient material coverage, incorrect spoil board.

  3. Faulty sensor or wiring
