Hello,

My boiler has been getting progressively worse and worse and I'm literally getting just cold water out the hot tap now. the diverter valve seems to be working fine, and i tried putting some limescale remover in the secondary heat exchanger after cleaning out the central heating system and adding protector afterwards. There is a fault code that come up that means 'central heating thermistor flow faulty (open circuit)'

Someone please help, i just had fill my bath with kettle water, haha!
