Pymp led flashing

[Greg38]

Hello

The led is flashing green... no issue for the moment.

I saw on the forum there is a pump node to check but didn't find it (I looked near the pump and near the power link r5 at the back of the camper).

My camper is a rimor horus 45 from 2000.

Thanks for your help

Hello

I suppose that the problem is on Bus cable from control panel to or main board (poverlink). We suggest to check if there is a no good connection on it or change complete cable with new.
