Kingspan Aeromax not producing heat and ice cold rads

I’m new to this forum and any help would be most appreciated.

I’ve got a 8 year old Kingspan Aeromax ASHP which provides hot water and central heating via radiators with no underfloor heating.

The system has stopped producing hot water/central heating. Initially I thought it might be an air lock or blockage as the unit starts up fine, the central heating pump kicks in but no heat coming from the rads. I bled the radiators and cleaned out the large brass in-line filter near the pump but still with no joy.

The really strange thing is that instead of the rads heating they get ice cold, so much so that condensation appears on them and the pipes.

It seems as if the system is working in reverse by cooling and not heating?!!

An error message did appear once on the panel which was code 15 which is exit water thermistor out of range but it only did it once but assume this is due to the cold water temperature?

Any ideas what the issue is before I have to shell out of a new unit.

Thanks
