Product review (3 stars): Not compatible with reverse osmosis treated water.
This unit was installed in a summer home in 2007. The entire subdivision is supplied with reverse osmosis treated water by the Municipal Utilities District. The unit has been used for less than 100 days since it was installed since it is in a vacation home. It has been cleaned according to the owner's manual. I have had zero problems with this unit until the past three months when I noticed black specs of material in some of the ice cubes. I delivered it to an authorized Hoshizaki service company and was told that the black specs were coming from the evaporator plate that makes and shapes the ice. The nickle coating was flaking off. I was told that the pH of the reverse osmosis water was too aggressive and was causing the nickle coating to fail. The cost of parts and labor to replace the evaporator is $1000.00. Had I known that reverse osmosis water would cause this problem I would never have purchased an Ice maker.

Update 2/2/2017. I called the office of the water district and asked what the pH of our water was and was told it was 8.0. This is not acidic water so the explanation I received from the Hosizaki technician does not make sense. I have written the company for clarification.
