Amber fault on MHCP_LED model B

[Jetcamper]

Dear support team!
The waterpump symbol on the control panel continuously flashes amber and the pump does not react. Complete reset of the panel does not help and all connections seem to be ok. The led on the distributor box flashes green and all fuses have been checked. I cannot figure out the problem and the instruction manual does not adress this fault either.
Could you please give any further advice?
Thanky you!

Hello. Probably the problem is on control panel or cable from control panel to poverlink. If the cables are OK we suggest to go to a dealer and check the system.
