How to fix a worcester bosch 28i please?
My boiler was turned off over last weekend when it was freezing. The system was turned back on last wednesday but after making a squealing noise the pilot light went out and there is no heat or hot water.
The pressure is at 0 and I have tried to repressurise it but the key turning has made no difference and it is not filling.
The green light and both red lights come on but when the water is running the red light begins to rapidly flash. Is there anything else I can do?
