A Rapido whose heating stays cold or cuts out after a few minutes usually points to an interrupted fuel supply, a faulty circuit board or a dirty burner.

A Rapido whose heating stays cold or cuts out after a few minutes usually points to an interrupted fuel supply, a faulty circuit board or a dirty burner. With a Truma Combi or Alde system, an empty gas bottle or diesel shortage is the first suspect, followed by poor 12V supply or a seized fan.
The exact cause depends on the type of heating: Truma Combi (gas or diesel) or Alde (water-based). A thorough diagnosis is essential to avoid unnecessarily replacing expensive parts.
Rapido fits different heating systems depending on the model and year of manufacture. Most recent campers have a Truma Combi on gas or diesel, while the higher models are often equipped with an Alde wet heating system. Each system has its own typical quirks, but the symptoms are similar: the heating blows cold, switches off after a short time, or does not start at all.
With a Truma Combi on gas, an empty or frozen gas bottle is the most trivial cause. Also check that the gas tap is fully open and that the pressure regulator is not faulty. In the diesel version, a blocked fuel filter or a faulty metering pump can be the culprit. An Alde system works with a circulation pump and a heating element on 230V or gas; an air bubble in the circuit or a faulty pump often results in a cold radiator while the boiler does get hot.
Electronic faults occur in all systems. A faulty circuit board, a poor earth connection, or a flat leisure battery can cause the control to fail. If possible, read the fault codes via the control panel. Also consult our general explanation about camper heating for a step-by-step guide.
Costs vary widely. A simple cleaning of the burner or replacing a temperature sensor usually costs between 100 and 250 euros. A new circuit board or circulation pump can amount to 400 to 700 euros, including labour. With an older unit, it is sometimes no longer economically viable to repair it. Then consider whether you would rather sell your Rapido instead of investing in an expensive repair.
