Air Con issue please

Stateroom Air Con works well

The Salon unit throws off the “HPF” code… tried running the fan only, the fan will NOT run either.

I read the many posts about priming the raw water pump… however, the strainer and pump are feeding the Stateroom Air fine…

How can I isolate the salon raw water feed and prime that separately ?

Many thanks,

Fixed it.
Documenting it here for the Tugnuts Knowledgebase.
Bought a <$4.00 female garden hose-end replacement at the hardware store. I will try to post a photo of this simple, small device that will fit in the boat tool box.
1) removed the rubber hose from the water pump. The long hose that ultimately connects to the A/C unit. Note, the hose was difficult / impossible to remove from the pump. My boat pal suggested using a heat gun and soften the hose from the barb. Hose end came right off… a great tip.
2) inserted the new female hose end to the long runber hose. Attached a garden hose to the new female hose end and turned the water on. Let it run for a few minutes. The water came out of the 2 hull-throughs.
3) removed the garden hose and new female hose end and reattached the long rubber hose to the water pump. Turned on both the Salon and Bedroom A/C units. Worked perfectly.

Re the attached photos above:
First pic shows the female end replacement for a household garden hose I bought at the hardware store.

Second pic shows the “blue” colored Marina garden hose attached to the female-end replacement part … which is inserted into the long rubber hose that ultimately attaches to the A/C unit…( that is normally attached to the black & white colored pump)
