Customer service is extremely important to Wolf. The aim is to provide our customers with safety and reliability. To ensure our service hotline team can give you the right advice, please have the following information ready: the age of your system, the appliance type (can be found on the type plate) and the control unit accessories. We would like to point out that as a rule, warranty claims must be submitted to the seller of the system (installer, wholesaler). Service visits from Wolf customer service representatives can be requested by the installer, wholesaler or owner of the system.
