Potterton puma 80 CH not working

[AdamSmith]

Hi all,

Just recently moved into my new home, which is fitted with a potterton puma 80. Its worked fine for a month that we have lived here, but today the CH stopped working. The hot water still works fine but the radiators are cold.
My boiler seems to fire up and the CH flow copper pipe feels very hot but the CH return pipe is cold.

Any idea's?

Ive searched the internet but cant really find an answer

Thanks, Adam
