Tupperware does not stop "smells" very well.

What kind of feed line do you have to the refrigerator?

Plastic lines can allow anything in the kitchen to get into the water headed for the ice maker.

A copper line does not have this problem.

It almost sounds like you are not using the ice very quickly, allowing multiple defrost cycles to occur before using the ice.

During a defrost cycle in the freezer the temperature is forced to rise above 32F by a small heater to melt off frost.

This affects things in the freezer, but especially things like exposed ice in the ice maker bin.

Before tupperware the smell was bad. After I don't notice it.

The feed line is the one that came with the fridge. GE - 25.0 Cu. Ft. Side-By-Side Refrigerator with Thru-The-Door Ice And Water - Stainless-Steel
Model: GSH25JSXSS
I think it was plastic/braided stainless steel. Any tips on where to get a copper one?

During the summer I go through the bin every few days. Right now it might take a week.

How often does the fridge defrost? I bought it 6 months ago.

Before you get excited about tearing anything up, get some bottled water that you like the taste of and make a few trays of ice out of it manually. Consume some right away. Wait a week before consuming the balance. Suspect it will tell you everything you want to know.

Basically saying I suspect your problem is the quality of water in the first place combined with rate of usage. I doubt very much it's the supply-line itself. Ref. filters are typically piss-weak substitutes for what's really needed -- more for sales-appeal than actual function. Connected up RO supply typically gives good results. If it sits around for long time, it will get a stale taste even if there's nothing else sharing space with it.

In any event, don't beat yourself up too much over it. That good clear ice you like in restaurants and stores typically comes from dedicated machines with upscale filtration and is turned over quickly. As close as you'll come at home with your frig. would be RO supply. If you can do something like that and bag some when the bin's full, you may solve the problem.

Copper tubing is available at the big box stores, but run the test first to determine the source of the off flavors.

I do have one other thought if you're a water/ice snob.....like I sort of am........

Good tasting ice comes from good-tasting water. I also prefer actual cubes or cylinders as opposed to the crescent-shaped pieces most ref. ice-makers produce. I resent the way they cling to the curved sides of my glass and make drinking a nuisance.

If you want, you could simply make your ice in cube-trays from whatever bottled water you prefer and double-bag them for later use before they've had time to sit around at all. Somewhat inconvenient, but does solve the problem.

Got news for you, homebound....it's already going on. Problem is, the total market is so small and so unwilling to spend nobody wants to deal with them.

I, myself, "invented" -- actually stole from the RV folks -- this pump affair that would supply the sink and fridg on-demand and at requisite pressure any type of water quality desired. Unfortunately, the only customer was myself. System was brilliant, if I may be forgiven my arrogance. Worked trouble-free in my own home for 18 years.....but nobody wanted it. Well, they wanted it but thought $200.00 was too much to pay. So much for my contribution to the advancement of western civilization. : )

So.....good luck with that.

Thanks for all the tips! I have access to carbon filtered water, RO water, and Arrowhead water at work. I am very picky about water and ice. Normally I don't drink much RO water as I don't taste anything but that might be perfect for making ice. I'll try filling up a empty bottle and bringing it home and making some ice.

I've tried the ice at work. There are 2 GE canisters under the sink which provide carbon filtered water to the fridge ice maker. During the summer usage is really high and you are lucky if there is enough ice to fill up a glass. That ice was a bit better then the ice from my fridge but it tasted similar.

Mostly I drink the Arrowhead water as it has a pretty good flavor.

Some more background info. I've never come across any ice at other people's homes in Southern California that I liked. I tried the bagged ice for sale at the local supermarket and that tasted similar to restaurant ice.

Anybody know how they filter the water for the ice you get out of the soda machine at restaurants?

IMHO best water for ice is distilled which is flavorless. Next best is RO below 20ppm TDI. Next is bottled water that you think tastes best or least-offensive. After that you're talking choose-your-flavor.

The filters in restaurant ice machines are typically charcoal stacks followed by 5-micron particulate filters. You may find some that use RO plus charcoal but I suspect uncommon....unless you're in an area like I'm in where the tap water is really terrible-tasting. RO units more common here. If you're friendly, I have little doubt your chosen restaurant owner would be happy to take moment to discuss his ice machine and filter. Might even be flattered that you noticed.

Can you get a filtration system with charcoal stacks followed by 5-micron particulate filters for home use?

There are a bunch of water stores in town that sell water that has been filtered.

I think I'll go and sample their water.

Activated charcoal filters and various-micron sized filters are pretty common and sizing is somewhat standard. I would think hardware stores and big-box stores would have all the components needed likely combined with various displays showing you how to do it. Typical set up would be charcoal canister followed by micron canister connected in-line by the usual fittings. Not at all hard to figure out. Would be similar to RO set-ups you may have seen except without the RO membrane cartridge or holding tank. Just pass-through filtration. And much less expensive.

Can't speak to quality of this unit but the configuration is quite typical. Linking to give you some idea of the probable set-up. Similar units are widely available.

Here is a link that might be useful: example of carbon/particulate filter configuration

I think any ice made in an icemaker by a frostless refrigerator tastes like the frost that we used to have on the sides of freezers (you young 'uns probably don't remember that), regardless of the water used. I live in the NW where we have fabulous water, but I always buy my refrigerators without an ice maker and simply buy bagged ice. The difference in price and electricity used buys a lifetime of it. I saw a story once about the way they make ice commercially and the filtering and extreme low temps used for quick freezing help make it free from impurities - impossible to duplicate at home.
