Slow flashing light

Post  Nupp on Mon May 14, 2018 10:18 am


We have a Pulsa coil A class and do not have any hot water unless we press the boost button. I have read multiple other entries on this issue and obviously it can be a number of different issues that could be causing it. This did happen a while back but it seemed to sort itself out.

From looking at the fault lights inside the unit (2 x 7 segment displays) there is no light illuminated for the 'Off peak supply present'. Could this be the issue that there is no eletrical supply enabling water to be heated on off peak? If so will this require an engineer?
