my Ariston Euro combi A/23 MFFI has suddenly stopped working. currently have it just set to hot water as no central heating on yet. No hot water from taps. checked the unit and dont seem to have a pilot light on or and LED displays over the on/off button or the reset button.
have tried changing the fuse as it looked like a power failure, but this has not helped. It doesnt seem to want to reset the pilot light or turn on at all.

any ideas anyone??
