Has your boiler emptied itself? Has the safety/drain valve opened?
To protect the system in your motorhome or camper van, the vehicle automatically drains the boiler at an interior temperature of 3°C. This is controlled by the so-called frost monitor. Please heat the interior to prevent this effect.
If you have any further questions, please do not hesitate to contact your sales partner. You can find an overview of all Carado dealers easily and conveniently in our dealer search.
