Hi Tellie. I was referred to you by GordMay. We have a Spectra 1000 that is about a year old. We were in the boat yard last week and I turned off the water maker. We are now back in the water and yesterday I turned the unit back on and restarted the auto flush. I than went outside to see if there was water coming out and it was not. I than opened the seawater intake seacock and the fresh water went out there. Somebody told me it goes out there for a few seconds than goes out the side. But the water just kept going out the seawater intake. I opened the relief valve and there was a whistling sound and the water went out the side where it normally goes. I have never had to do this before. Thanks for any help you can give me. I have posted this question on the forum under Water maker problem.
