We have an icemaker that makes ice cubes; however, they taste moldy and your hands smell moldy when you finish putting them in a glass. Is there a way to resolve this problem other than getting a new icemaker? We did change the water line once and it helped for a very short time.
If your icemaker is working correctly other than the smell and taste, and that no other sources of water have any issue, then I think that a cleaning process is in order. First, make sure that the water line (which you said you replaced) is copper and not plastic. If it is plastic, be sure to change it over to copper, as the plastic lines could be part of the problem.
Begin the cleaning process by turning off the valve to the icemaker line. This is usually in the basement, and has a small ¼” line running to it. Then remove the icemaker unit from inside the freezer to clean it. Each unit may be slightly different, so I can’t give you exact directions, but you’ll need to remove the plastic tube that comes from the back of the freezer to the top of the icemaker, allowing the water to enter into the ice tray. The icemaker unit usually hangs from two screws, which may need to be loosened slightly to lift the unit out. However, the electrical plug will still be attached, so once the unit is off the screws, unplug the unit from its receptacle. You’ll now have the freedom to take the unit over to the sink.
The icemaker unit has a motor inside of it, so do not immerse the unit in water. Instead, I would suggest as thorough of a cleaning that you can, without dipping the unit in water. A bleach solution might be a good idea, using a sponge to clean. Afterwards, be sure to rinse the unit as thoroughly as you cleaned it, and then let it dry completely before reinstalling the unit.
My next suggestion is to consider purchasing and adding a water filter to the ice maker line. The larger hardware stores carry these for about $15 – 20, with all of the parts needed to add the filter to an existing line. The filters last for about 6 months. Replacement filters cost slightly less, and take even less time to install. In reading reviews on these filters, I think this will solve your problems.
After the cleaning and adding of the filter, carefully move the refrigerator back into place, being sure not to pinch the copper water line. Once your icemaker starts making ice, I would suggest that you throw away the first batch or two of ice, in case there were any cleaning agents left inside the icemaker.
