Ariston keeps losing pressure E02 error code comes up!?
My Ariston condenser boiler loses pressure when its not fired up.... looking at other posts I have checked for leaks and which there arent any but I put a bucket by the blow off pipe outside and that has filled up.... It works ok once I refill from the 2 taps on the boiler but when its off overnight its empty again in the morning.... any ideas??
