Potterton Suprima Information.

If you are experiencing intermittent problems, then the chances are that the circuit board may be failing. It is a very common problem, with the boiler shutting down to red lockout randomly.

We can help you with this problem, we do a refurbishment service for these boards at a fraction of the cost of a new circuit board, just search for your matching Suprima part on our site.
