Re: Air conditioner seawater pump won’t start

Dean Gillies

Hi Olivier and Ruedi,
Sorry I should have said that I did spin with a screwdriver, and the spindle runs freely.

Now that I know that the pump should start immediately, that is very helpful.  It seems that there is a problem with the relays.

i will try again with all three systems powered up to see if that makes a difference before I start looking at the relay board. 

Many thanks
