Hi Andrew
You have got great responses here already, but if you still need support, you can complete a quick technical support form at the bottom of the main combilift.com web site or direct link https://warranty.combilift.net/technical-support-form/. The form only asks for the minimal info so the team can quickly help you. There is no login required and no charge for this support.
Combilift has Technical support technicians across the world including the UK specific technical team and they will get your submitted form automatically.
You can also request access to our knowledgebase where you will find more information available. Hope you get sorted.
