Hi,
have a warm new year everyone, it seems I will be having a not so warm one.
I have a Ariston Micro Genus II combi boiler in the flat. Today I noticed that there is a problem: When taking a shower, the water was hot for around first 15-20 sec, then it becomes cold and does not heat any more.
What happens with the boiler meanwhile - the HW light switches on as normal (showing it is heating HW), the temperature dial shows 99 (Not E99, also not sure what does it normally show), the flame dissapears in 15-20 seconds, leaving the HW light on with the temperature dial still showing 99.
(So I guess boiler thinks the water is 99 degrees C hot and thus stops heating.)
Any suggestions what this might be?
