Hi guys, We have a Megaflow Eco cylinder and no hot water. The Tundish shows it’s long overdue for a service and the pressure value is showing under 1 bar of pressure. Is there anything I can do myself in this situation or is it at the point that I should get someone in? Photos attached. Thanks for your help. Mike
Could be the programmer, zone valve or the thermal cut out (overheat) that’s operated. It will need some investigation. The thermal cut out is a good place to start. It will be under that grey cover. Be careful as it’s potentially got live cables.
