spd121d

I have a speedvac without a manual... It's the speedvac spd121d, thermo now produces it, but they are slow to reply

If anyone else has one of these, could you tell me what it means when it won't open or respond to any of the controls, and the number 8 in the display is the only sign of life???

It uses an external vacuum system which is working fine.
