Just been to one of these piles of pap intermittent hot water fault code e 33 checked it looks like aps playing up .
Just had a gander at fault codes and seems to confirm however not to familiar with theses boilers anything here that can trip you up?

remove the flue restrictor first,they corrode with age is it a HE version or SE?

 

[hammers4spanner]

Its the HE version

 

[Billy Bob Bob]

Its the HE version

restrictor will either be in the spigot for the flue on the top of the boiler,or in the inlet for the flue on the condensing hex,take it out and bin it,see if that clears the fault first
