Very noisey apollo 15/30 B boiler

[vernon0077]

hi guys and dolls

i have been bleeding my upstairs radiator as the top of the radiator wasn't as hot as the bottom

now my lovely little boiler is make so much noise it wake ''war lass up'' when it switches on in the morning, in fact in sounds like the plumbers already arrived as its banging and shaking all around

i fear the water may be low or the boiler needs a flush

with my other boiler (sealed) type
i knew what to do but there is no water pressure gauge on the front of this boiler and there is 2 x water tanks upstairs in the loft

i've just been in the loft and there are two water tanks
both floats are working correctly and both tanks are clean and full

please advise
