Have had an Intergas SB30 installed since march 2013. During this very cold period, yesterday morning the boiler cut out. What was happening was the Operating Code showed 4 for a short time dropping down to 3, repeating this several times then cutting out, the Temperature Display showing 4...

Fitted new control valve, NO noise. Thanks to all who replied to this thread.

Thanks. Off out to get a new valve!!

Thanks for that. I have finally been next to the valve when its banged and its definitely the valve. Have emailed Drayton to find out if fitting the valve the wrong way round is the problem. Will post details if problem solved. Many thanks

Thanks for that but its a two way valve. What I have noticed though is the valve has been fitted the wrong way round. Would this make the noise. Thanks

HW off, CH on. When the thermostat trips out there is a very loud bang in the system. This does not happen every time but always happens when tripping out. Bled the system, all radiator valves open, boiler 4 years old. Any ideas?

I'm replacing a monobloc mixer tap with new. Do I need a non-return valve in the pipework and if so which pipe, the Hot or the cold. There isn't one in the existing pipework. Regards

No the noise hasnt been there all the time but I did replace the 3way valve + actuator and also replaced the actuator of the zone valve. Still the noise. Regards

Many thanks for the replies The reason for asking is that the system I have at present is the Y plan with an additional zone valve between the 3way valve and the HW cylinder. What is happening when HW is called for there is a loud bang from the 3way valve. If I change it to S plan this would...

What are the pros & cons of S plan as against Y plan

Saunier Duval SB30e I have had this problem for over a year with a competent CH man visiting 6 times and not being able to sort the problem. Just to explain that when the system calls for heat or HW the boiler starts up then after a few seconds goes to lock-out. Previously with the pump on the...

Mick Thanks for that. How should the 2 way be wired in? when I took the old one off it had 4 wires, 2 of which were taped up together doing nothing. These I think were from the internal switch regards

Saunier Duval SB30e boiler Drayton MA1 3way Valve Sunvic SZ2301 2way Valve On my system between the 3 way valve and the HW cylinder there is a 2 way valve. The problem is more times than not there is a hell of a bang from the 3 way valve when HW is called for as if the 2way is fighting the...

Sometimes when the CH or HW calls for heat the fan comes on and just as the boiler fires it goes to lock-out. Replaced circuit board, ingnitors, temp sensor and presure diff sensor. One thing that also happens now and again is that there is a bang as if a valve is sticking. (Have replaced the...
