Fix Fault Baxi Bermuda

I have a Baxi Bermuda 2 inset fire only, ( no back boiler ) I press the button to light it, I hear it sparking for a few seconds then it stops but does not light ? any advice ?

When my CH switches on, on the timer my hot water turns on as well even though it is switched off, why does it do this?

burner lights and burns ok with boiler front cover off as soon as you replace front cover the flames come out from under the front cover i have smoked the flue and is ok can you help thanks john

I have a baxi Bermuda w2. Hot water working but rads are not. Any suggestions plz!

my system is now not working - the pilot light will not fire up and i think my pump needs changing - how much will this cost and for a service also.
