Hoshi Flaker Yellow Ice

[chilltech]

I have a client that is complaining of yellow ice. I cleaned the machine today-was pretty scaled and slimy. I ordered water filter replacement cartridges and will replace those tomorrow. What else might cause this problem?

[MikeySq]

bad bottom seal maybe??

Thats what I was thinking also. Guess I was hoping for something else. Thanks!

Disgruntled employee? :whistle:

Anyone complain of getting sick moderate or really really sick after drinking/eating ice from machine? Could be co2 from pressurizer tank leaking via back flow preventer the co2 reacts with the copper and makes carbonic acid.

I am very familiar with bev. systems. Where does yellow ice tie in with carbonic acid?

Ice can be discolored IE. Yellow from carbonic acid.

I got that you are saying this...Have you seen this or can you state cases where this has happened?

Carbonic acid can present from a brown to yellow depending on concentrations of minerals gas and copper or whatever.
But if it gets you off heres a pic!:D It looks yellow to me.

No need to be a jerk about this. I was simply asking if you have seen carbonic acid make yellow ice. I can pee in ice and make it yellow! A science experiment is not the same as an ice machine producing yellow ice.Not trying to get you upset but again I ask have you seen or have any proof of carbonic acid making yellow ice?

I was being sarcastic sorry if i sounded like a a$$ to you, yeah I've seen it yellow in that link there are years of reports in there it's amazing check it out it's like every back flow preventer disaster big or small ever kinda sorta.

I tried googling yellow ice in relation to carbonic acid and only came up with yellow and brown water from an experiment. It would seem to me that the level would be rather high to produce yellow ice. I would think a whole lot of people would have been sickened by this and the board of health would be investigating. Oh well...I'll look thru those links a bit to see if any have a case with ice. It is usually in the soda.
