Vectra M1 switches off

[Rando]

my Vectra M1 always switches itself off as soon as I switch off my Vortech pumps. This is of course unfavorable because the water level in the filter compartment rises threateningly. I don't have the Vectra on the same power distribution board as the Vortech pump, but it always switches itself off and even jumps to feed mode. I checked everything in Mobius, everything is OK according to the app. The Vectra has also not been running constantly since the last firmware update. The water level in the overflow chamber changes its height every minute. either it splashes or it slurps and gurgles. Adjustment is somehow no longer possible.
