I told him that just THREE minutes after he first posted on here!
But he has steadfastly ingored that advice and instead wants to illegally take his boiler apart.
If it did have gravity hot water then I would expect it would be VERY seriously kettling!
sneakyprawn - nobody has spelled out yet that you don't have separate heating water and hot water water.
It's not a combi.
It probably gets hotter doing the HW though.
Leave the high/low switch on LOW.
Don't ever take the cover off this boiler - they're dangerous boilers.
Just do as you're told!

NO, it's not limescale.

Not withstanding all the above, it is worth with this boiler to check the pump impeller is clear. The flow rate through this boiler was always critical [as it is with many]
I did often find a black glass hard deposit/s blocking the impeller, seemed more prevalent with the apollo for some reason than other boilers with similar HE type.
Anyways worth a check, if all you wish is to keep it going awhile longer.
