Ps can you help...Have an Ariston Microgeneous 27 MFFI - ignition failure..and Drayton Wireless on wall next to Boiler has red Alarm button on constantly. So basically switch boiler on, ignites, pressure gage all good and then CH and HW kicks in and comes on...then after about 2/3 mins the reset led light come on which the switches heating off and HW goes cold....I then press the reset LED Button and all goes back to normal but again after about 3 mins the CH/HW goes off..
