there is no power to the ignition control board could this be a problem with the main pcb. this problem seemed to start when the gas board changed our meter. initially l had a problem with the condensate drain, l have sorted this out l know it sounds a bit silly but could the new meter be producing more condensation

most likely a fault with the air pressure switch or fan. and no, gas meter should not affect the boiler unless there is, or was previously a problem with the gas pressure.
