A/C not working

[Matty]

The Webasco air conditioner sends a E3 error code every time I try and power it up. E3 code says compressure low pressure protection. The water pump does not come on and it runs for about one minute before the error code comes on. The vents are all clear.
Unit is on a 2018 R27 not quite one year old. Any thoughts on what to check? Any idea if water pump should be one of the first items to cycle on?

Matty,

It sounds like the ac pump is air-locked, you need to prime the pump. Typically this can be done with a hose at the dock and in the water, turn on the hose and point directly into the AC pump feed hose port on the strainer, then turn on AC and pump and should get it to fire off. Once the pump is running open your seacock and turn off the hose. If you remove your boat from the water after running the AC and leave the seacock open it can lose its prime. Best practice is to close the seacock before removing the boat from the water. Let me know if you have any questions and you can always email me direct for a quicker response. Hope this helps!!

Thank you,
Kevin Lamont

Is there water flowing out?
If not need to prime pump, mine primed by removing out hose and running until water flowed, then replace hose.
