What does error E020 mean on a Riello Family KIS boiler?

Error E020 on a Riello Family KIS boiler indicates low water pressure requiring the system to be charged. Do not attempt to repair gas appliances yourself. Switch off the boiler first, then check the pressure gauge. If pressure is below 1 bar, you may repressurise to between 1 and 1.5 bar using the filling loop, then press OK to charge. If pressure drops repeatedly, contact a Gas Safe registered engineer to check for leaks.

What does error A04 mean on a Riello Start Condens boiler?
