My grippa system stopped working in October. It was hardly ever used and only bought in February.  First one of the controllers just stopped working  and after a couple of weeks the whole system stopped working.  The red light is on but nothing happens.
Anyone got an idea of what may be wrong.

Why would you spend thousands of pounds on a hot water system and hardly ever use it?or get it fixed while its under warranty?

If you have a marina nearby then a good boat engineer will most likely have the diagnostic equipment for a Webasto.
Servicing although simple (usually they coke up) certainly won’t be cheap.
