My Ideal C80FF(I know its c**p) boiler goes into a continuous loop of firing up for 20secs then shutting down for 20secs then firing up for 20secs etc, etc for both DHW and CH. Can anyone suggest a likely cause? The fan and pump continue to run after ignition goes out.
Thanks in advance.
PS. I had the Ignition PCB changed last year when it wouldn’t fire up at all.
