Changing pump combi boiler

[mikeerhymes]

Hi

The pump has been very noisy of late with my vaillant 830 combi boiler so have decided to get a new one before this one fails!

It looks pretty straight forward to change but is there anything I need to watch out for or any advice?

Cheers

Anyone?

I don't know anything about these gas things, but on the jolly Heatslave I buy an identical pump and change the head only....4 allen bolts, 5mm key.

Not familiar with an 830 but pumps are a pain on most recent vaillants. If the new one has got a different colour label (black or white) you can't change the head only, you need to swap the whole thing.
