Are you travelling with your HYMER camper van or motorhome in winter and your step cannot be extended or can only be partially extended?
This is most likely due to an icy step mechanism. In this case, the protective device - the anti-trap protection - has been triggered due to overload current.
Please clean the entrance step and carefully remove the ice. This is usually sufficient to restore the function of the step.
If you have any questions, please contact your dealer.
