How to clean heat exchanger

[Janz]

Hi,

reading all the related post and the stuff that I already tried I really think that the "Heat Exchanger" of our "Worcester 24i Junior" (not greenstar) needs to be cleaned or even replaced.
I have looked at it but it seems to be inpossible to take the "Heat Exchanger" out of the boiler... please does anyone know how to do it?

Thanks a lot
Regards

ok, I thought it was a greenstar.

Does the boiler have the controls on the front behind a drop down door, or are they exposed all the time? (greenstar behind door & standard 24i exposed)

Hi, it's not greenstar. The controls are exposed.
Thanks
