A malfunction always comes at an inconvenient time. First look at our page for malfunctions if we are carrying out maintenance on your installation or if we are already working on solving the malfunction. Is there nothing online? We would like to solve your problem as soon as possible. Call +31 (0) 85 - 130 48 29 (local rate) and indicate that it is a malfunction. We are available 7 days a week, 24 hours a day.

Please note: 

  • During office hours (Monday to Friday from 9.00 to 17.00) our customer service will assess the problem together with you. If necessary, we will instruct our maintenance party to fix the problem.
  • Outside office hours, reports are accepted by our emergency services. If your malfunction is not urgent, our breakdown service will accept the report and our customer service will contact you the next working day.
