800 Final vacuum value not reached The required final vacuum value cannot be reached. Check the vacuum pump.
801 Vacuum drop An unacceptable vacuum drop has occurred.
802 The vacuum does not increase No vacuum increase could be measured. Check the following points: Is the firing chamber tight (no
(self-test) contamination on the sealing surfaces)? Is the vacuum hose connected? Is the vacuum pump connected?
Is the fuse F1 o.k.?
