If the Alde heater in your motorhome does not light, this is particularly critical when it is cool outside and you are dependent on heat. A functioning heater is essential for your comfort and safety when C-Class.
Recognising ignition problems
Ignition problems with your Alde heater can become visible through various signs. A common problem is that the heater cannot produce a gas flame, which affects both comfort and safety when camping. Typical symptoms are error messages on the control panel, no ignition noise or a strong odour of gas.
These problems can occur with various models, for example with the Alde Compact series
Possible causes at a glance
- Electrics: A missing 12V supply or a flat battery will interfere with the ignition mechanism and prevent the heater from starting correctly.
- Supply: Problems with the gas supply, such as a blocked line, an empty gas bottle or a closed valve, can prevent the flow and interrupt the ignition.
- Environment: External factors such as unfavourable weather conditions or severe temperature fluctuations can affect the performance of the heater and lead to ignition problems.
- Security systems: The safety system could have activated the crash sensor, making ignition impossible.
Solution approaches
In the event of ignition problems, the Alde heater usually displays an error message on the control panel. This will help you to recognise the specific causes and react in a targeted manner.
- Error code E01: This code indicates an interrupted gas supply. Check that the gas bottle is open and sufficiently filled. Make sure that all valves are free and open.
- Error code E02: This indicates a problem with the power supply. Make sure that the 12V supply is active and that the battery is fully charged and correctly connected.
- Error code E03: This error indicates that there is a blockage or fault in the wiring that is preventing ignition. Check the free flow of gas or air and look for dirt or kinks in the pipes.
- Error code E04: Indications of a technical problem in the ignition module. An intensive inspection by a specialist is recommended.
- Error code E05: If there are problems with the safety device, e.g. the crash sensor is activated. Reset it to enable ignition again.
Irrespective of the error messages, the following general measures should be taken to rectify ignition problems:
- Ensure electrical and gas supply: Make sure that all electrical connections of the heater are firmly connected and the battery is fully charged. Check the gas bottle for sufficient filling levels and open all valves completely to avoid blockages or leaks. These simple steps will help to guarantee the energy and gas supply and keep the heater in good working order.
- Consider environmental conditions: Adjust the settings of your heater to harmonise better with the surroundings. In extreme weather conditions, such as severe frost, you should ensure that the heater is operated at the optimum settings to minimise heat loss.
- Reset the security system: Activate the crash sensor to enable ignition again.
When is professional help necessary?
If the Alde heater does not ignite despite all the suggested measures or if problems continue to occur, it is advisable to contact a qualified specialist company or Bürstner service partner to identify the cause of the problem and safely restart the heater.
⚠️ Safety note
Always ensure a well-ventilated environment when implementing the suggested measures to avoid the risk of gas accumulation. Visually check that all gas bottles and pipes are safe and tight without carrying out any repairs yourself. Keep away from naked flames and sources of sparks when operating the heater. If the smell of gas persists or if you are unsure, switch off the heater immediately, open the windows and contact a qualified professional.
💡 Our tip
Always have a detailed checklist ready that includes the condition of the gas bottles, the battery charge and the settings of your heater. A preventive check can help to identify technical problems at an early stage and initiate the necessary measures before you set off on your journey.
