You do not need to diagnose the fault before getting in touch. A short description of what you expected to happen and what actually happened is a useful starting point.
Include these details where available
- The product models and the installer or vehicle details relevant to the installation.
- The exact wording of any warning or fault code, with a clear photo if possible.
- When the issue started and whether it happens every time or only in particular conditions.
- Which charging sources and appliances were in use at the time.
- Any recent changes, servicing or new equipment.
- The normal user checks you have already completed, following the manuals.
Photographs of the display and accessible labels can help. Do not remove covers or disturb wiring to obtain them. Do not send account passwords or other credentials.
Where to start
Your installer is often best placed to explain how the vehicle's components have been configured together. You can also use the Litherra contact form to ask for help with product information or the next step.
If there is visible damage, unusual heat or a burning smell, stop using the affected equipment and seek qualified assistance rather than continuing tests. The support information above is for reporting an issue, not permission to keep operating faulty equipment.
