I have an Ariston Clas He system with an error code of 1P2?

When running a Hotwater Tap the error 101 shows and the boiler shuts down with the red light showing.
Pressing the Reset button shows the error code 1P2.

This is related to a circulation issue, could be the pump or a restriction on your system such as sludge or limescale
