We’re in the Cairngorms, having driven up today.

Parked up at a beautiful spot after 12 hours of travelling and put the hot water on. No issues.

Followed a burn upstream for a bit to see the scenery and listen to the grouse, oystercatchers and curlew shouting their good news. Saw first ever snow buntings too!

Got back to the MH and turned the Truma from water only to water and heating, at which point the Truma lights went off. Nothing.

Checked the main distribution board fuse. Tested OK but was loose and dull. Replaced with a new one. Fit nice and snugly. Still no heating.

Dismantled wooden surround protecting the Truma and got to the control panel on the body of the actual heater. 10A fuse tested fine. Found a little red LED stabbing out a morse code-type message. 8 flashes

Does anyone have a list of the codes? They’re not on the Truma site.

HOWEVER! I googled the code sequence and the inter web came up with the solution: low voltage. This was the fault of the dull wobbly blade fuse, I reckoned. Having changed it I now know that’s what it was.

It would help if anyone was able to share the panel fault codes so we have a record of them.
