Servis M6160S, Soap Dispenser Hose Connections

I removed the soap dispenser to remove a blockage and, stupidly, did not take a photo before dismantling.
There are three hose connections on the back of the soap dispenser, two on the upper part and one on the lower.

The problem is that I only have two hoses so do not know which connections to use.
the two connections on the upper part have the moulded letters ‘L’ and ‘P’, the connection on the lower part does not have a designation.
