Hi Tony~

The water pump turning on….And the water pump pumping water are two differing problems…

We need to know which it is….

• Does the pump run when installed ?
• If not, does it have voltage ?
• If it runs installed…Have you assured it has good water supply ?
• Is it mounted below the outside waterline ?
• Have you tried to prime it…and how did you do that ?

These are all common questions to ask….The answers will help me help you…

Steve thanks for the reply

Does the pump run when installed ? No

If not, does it have voltage ? Yes

If it runs installed…Have you assured it has good water supply ? Yes, when I unhook the hose from the pump to the AC units its drawing water from the seacock.  When I took it out and conected a power supply to it, it pumps water very well…I'm confused here Tony…It runs & pumps water when out of the boat…Yet you say it has power when installed in the boat but does not run…If it runs with power out of the boat…The motor should run with power in the boat…Obviously it can't pump water without the motor running, so I would double check for 115 volts while connected to it's power source in the boat…

Is it mounted below the outside waterline ? Yes

Have you tried to prime it…and how did you do that ? No I did not sense it had water going into it, if I should still how would that be done?

Ok Tony…Like I say at the top of every forum page…I need some more info because my crystal ball is only so good…

How many systems on the boat ?…This could mean you have a pump relay if there is more than one system…Yes the pump relay has a fuse in it…It should also have it's own breaker in your main panel if there is a pump relay…and the pump relay board could be bad too…

You could also have a bad board in the Passport I/O control box that is not sending out power to the pump, or pump relay…

This is why I asked about power in the boat…You told me it had power but would not run…Have you actually checked for power at the pump with a meter ?

If you don't have a meter that's ok but you are going to need some way to test for voltage to find the problem…The only thing you can do is check the fuse inside the pump relay (if the boat has a pump relay) without a meter or voltage tester.

Hi Steve, ok still working on the same problem AC unit is giving me HPF, here is what  have done, took out the water pump and hooked it up to a power and it ran fine, put it back in and does not run, I have water coming in from the lake and cleaned the filter, I unpluged the cable from the head unit to try and reset it but still does not turn on the pump lastley tryed to force water into the thru hole and no help thier.  Lost on other ideas.

Hi Steve, I'm back with the same problem, so let me start over,

When I turn on my AC unit it runs for 2 or 3 min without any water coming out the thru hull and shuts off with a code of HPF.  So I one of the other boaters took the water pump out and connected it to a straight elect connect and put it in a tub of water and the pump shot water out great.  When he put the pump back into the boat still no water pumping out of the thru hull. 

I have cleaned the filters, strainer no help, I have water coming into the pump from the seacock based on when I disconnected the hose from the water pump to the ac unit with the seacock open there is water flowing.  I only have one AC unit on the boat it is a 2005 Rinker 270 Fiesta Vee.  I cannot seem to find any additional fuses other than the circuit breaker switch on the panel which controls the entire AC unit.  So bottom line something is keeping the control unit from turning on the water pump, and I hate to spend $410 on a circuit board if not necessary,  I appreciate any further assistance you can provide.
