Any luck with the Domobar, Daniel? To me it sounds like air trapped somewhere. Haven't had a look inside the Super, but did look a lot inside the Domobar basic model some years past. The plastic hoses can easily get bent or trap air. If so, keep pumping water through until you hear a change in the pump sound - if you have a tank machine it must be a vibration pump, they can take a bit of punishment.
I also second CakeBoy's suggestion about lowering the pressure. Going down to 8.5-9 bars was better. 12 is just some general setting they apply from the factory, you can change it by adjusting the return flow valve (some call it OPV, over pressure valve, but since you have the Super model there might be a possibility for misunderstanding here - this is not about the safety valve on the boiler!).
