Boiler shakes and vibrates before turning off - we think it is overheating causing the water to boil before switching off. Is there a thermostat in the system or is it in the control board as Approved Engineer seems unbale to solve the problem. New PCB part no. 5108434 fitted but is has got worse and we dare not use the boiler. PLEASE HELP
