Mend Ferroli Maxima 35C Boiler Fault Heating

Ferroli Maxima 35C water pressure switch problem?

I have a Ferroli Maxima 35C that keeps getting F37 faults. British Gas changed the electronic water switch 3 times and now they have told my wife that the system may need a power flush at a cost of around £500. Can anyone tell me why this may be the case and is this a common fault with type of boiler?

Thanks

Hi
Sorry I dont have an answer, but the same problem. My boiler is just 2 years old and perpetually gives me F37. The pressure is fine at 1.1 til I turn on a tap and it drops to .4 too low and shuts down. Did you get yours resolved OK, £500 sounds ghastly !

sue@aplaceunknown.fsnet.co.uk - like to hear from you. Many thanks and good luck.
