Hi Gary and thanks to all for info and

others news :

-the fun of LP pump works and the pump too : the water
flows out before the HP pomp starts.

-my electrical box is different from yours, it is a
previous model, I think, more simple.

At the moment it may be a problem of gauge and I'll
check it as you told me in detail. Thanks so much !

Anyway I have time , if necessary, to order it to Olivier
when I'll be back at home ( VENEZIA, IT ) next summer.
Now I'm in Venezuela sailing tomorrow to Cuba.

This group is GREAT !

All the best and..vento in poppa.

Hi Giovanni:

Regarding your post : " At the start the low press
gauge doesn't mark green and remains on red, but after 2

minutes ca the HI press starts and it is possible to
regulate the Restrictor valve and to have fresh water. No

allarm. It seams all working properly, also the Low

To trouble shoot this problem I suggest the following:

1. While you are in the engine room next to the low
pressure pump, have your

assistant start the watermaker. After approximately 20
seconds you should hear

the low pressure pump start. Approximately 90 seconds
later you will hear the

high pressure pump start.

2. Once the low pressure pump starts (if it does) and prior
to the high pressure pump starting, look over

the side of the boat and see if sea water is flowing out
the thru hole on the port side.

If the low pressure pump fails to start it could be due

A. Tripped circuit breaker for the BP pump (located in the
electrical box on the back

side of the water maker which is accessible from the port
lazerette , see my water maker picture folder)


B. Bad control relay on the the circuit board in the
electrical box (again, see the photos in the Watermaker

Service Folder)

C. Bad ganged relay in the electrical box.

You can manually set the ganged relay, thus bypassing the
control relay, by using the small lever on the

front of the ganged relay (see Photos). If manually
setting the ganged relay with its lever causes the low

pressure pump to run, then the control relay or its
circuitry is bad. Write back for instructions on how to

wire a manual override like Richard suggested.

If the BP pump Circuit Breaker is ok and the ganged relay
clicks and the pump doesn't run then you have

a bad pump (most likely)

If the pump runs, you have sea water out the side of the
boat, but you still don't show feed water pressure

at the panel then you have a faulty gauge.

Check to see if the gauge is leaking or the fluid in it is
discolored or cloudy. You can obtain a new gauge

from Amel by emailing Olivier Beaute at sav at amel dot
fr , as I have done so. Dont' bother trying to have

Dessalator ship directly, it is a nightmare. They
don't have any expertise in shipping or handling


The gauge is removed by removing the three screws on the
faceplace, then unscrewing the gauge

from the rear of the panel using a wrench. The gauge
merely screws into a brass manifold. These

are typical European non-NPT (National Pipe Thread)
threads. That is they are not tapered pipe

threads and therefore are difficult to seal. When
installing the new gauge you will need to seal the

threads with something, 3M5200 does NOT work.

Hope this helps, let us know what your finding are.
