Ive got the powerflush system machine on and connected to my heating system. I accidently left the boiler on, but disconnected the machine from the radiator. Now my boiler does not work and makes weird noises and the temp shoots to 100 - 115' degrees and makes weird noises. I just turn the boiler off as soon as this happens. I want to know,

What has damaged on the boiler?
How much will it cost to get it all replaced?
From where can i get the parts
And also tips on cleaning out my system (UK resident) (London)
Cleaning scale from your radiators etc, whats the best way to do it. Thanks
