I have a Bacharach at a Costco location in Parker Colorado that one of the sensors in the walk in cooler was flooded with water, the Bacharach then was reading no flow in the zone, I disconnected the hose from the box too see if it was the zone sensor, but it turn our to be the main sensor in the box, 

my question is, can I repair this with the maintenance kit ? or do I need to buy specific parts? or would I need to replace the whole Bacharach, and I ask this because if you see in the pictures, you can notice there is humidity inside the hoses. please let me know as soon as you can what parts do I 

need to purchase to get this fixed.

thank you.
