Hi,

You will need to do the regen to clear the code. However this may require your Local Kubota dealer if the drivers have ignored all directions on the screen to date. Combilift technical team can help you define next steps.

You can call Combilift directly and ask for the tecnical team.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.
This will go direct to the service team (it goes to the team assocaited with your country/region).
Plaese contact Combilift today and the team can advise next steps.

Thanks
Richard
