My boiler switches on for 10 seconds then off, hot wate takes ages and when it does come through it goes cold after about 5 litres worth and then warm again. I have had all the sensors replaced. The gasman thought it might be the PCB but dont want to waste £200 if its something else.
Any ideas?
Thought it might be the gas flow into the house as my cooker has no different between full gas and half, only a difference if you turn down to low.
If anyone who a goo dgasman than can sort this in the Lichfield, Staffs area would be helpful
