Ravenheat CS80 Boiler error

[Haze773]

Hi,

Ravenheat CS80 boiler giving error 10e and 02e which indicate high pressure.

But pressure is fine.

What else to check please?

Many Thanks in advance.

Well the 02e states pump circulation failure, so that coupled with the 10e would be looking along the lines of both, perhaps an expansion issue.
