Hi I have a ferroli optimax HE plus 31c, and every time we run the hot water for 3-4 minutes the water goes cold and it gives the error code of A01 which means the ignition has gone and I have to reset the boiler. I had the divertor valve replaced about 6 months ago, but it does the same when the heating is out on. Has anyone come across this problem before or have any advice on what to do as my plumber can't make it until next week and it's getting really frustrating having to reset the boiler every few minutes when running baths ir showers. Thanks in advance :smiley2:
