hi, my baxi 80 eco is igniting intermittently.. it has been doing this since i changed the heat exchanger.. i have also changed the diverter valve, and the temperature sensor. it has also been reset many times from the front and the reset switch just below the temp sensor. sometimes the boiler will not ignite at all. its happening with the H/W and C/HEATING.. PLEASE ADVISE FURTHER.
thankyou
