Mend Vaillant EcoTech plus Combi Boiler Low Pressure

How can I reset my Valliant EcoTech plus combi boiler?

How can I reset my Valliant Eco-tech plus boiler after power and water has been off for a while. It was OK before but pressure seems low now and boiler is not operating when it should. I have no user manual. Can I get one anywhere?

you can download the manuals from the vaillant website

You need to repressurise the system using the filling loop, you may have a leak somewhere, have a look around rads etc for any leaks. Or have the radiators been bled and system not repressurised?
