Ice maker will not make ice with Reverse osmosis filters

Just opinion from personal experiences. I have dealt with probably a double hand full of escalated issues over the years, especially on clear ice machines where the reverse osmosis system did have a negative effect on optimal ice production. On more than one case we would go through a couple of product exchanges before convincing home owner/ builder/ plumber to take the machine off the Reverse osmosis system and finally when they did low and behold the machine would start making ice and the intermittent issues would go away. That being said the manufacturers of the Reverse osmosis systems have come a long way with their technology / pressure regulation over the past few years.

Some argue and I tend to agree clear ice machines don’t need filtration on the water supply in most cases. The very nature of how they make ice separates most of the impurities and flushes them down the drain hence the label clear ice.

Again from my experience the Reverse osmosis issues seemed to be more prevalent in the clear ice machines than the traditional crescent cube ice maker that reside in most refrigerators.

I have also run across flow pressure issue and volume issue on ice machines where needle/ saddle / piercing valves are used to create a water supply to them instead of having a dedicated water supply plumbed to the machine.

Hope that helps.
