Any ideas please. Away for a few days been totally off grid and boiler( combi 4) has been working fine both for hot water and blown air heating. We moved moved today a to a campsite plugged EHU in and turned boiler on to heat up water. Green light came on then orange as expected however after 30 seconds both lights went off. Tried again and no lights came on. Check gas ok. Tried again green light then orange listened to boiler quiet whirly then turned its self off. No red flashing light on boiler indicating fault. Check main fuses ok replaced fuses tried again and all working. Now been on for 20 mins and it seems fine. Did notice that all three lights , on the boiler, orange green and red are all illuminated - is this right? Any thoughts on the problem please.

Got a similar problem.
Plugged in to EHU. Turned on Combi hot water (control panel lights lit) and left it for an hour.
Came back and water only lukewarm. No lights on control panel.
Tried it on gas only and still nothing.
So interested in the feedback you get.

Update. Boiler worked fine heated up tank of hot water. Turned it by off, used hot water then turned it on again and fired up with no problem. Not sure if it was me being paranoid but it did seem to take a bit longer to fire up. When running I looked on boiler and there are three leds showing. Is the red one meant to be on when running or does it mean a fault. It is not flashing.
