I have city water and I have this SAME problem. My question is if it's what the other guy suggests it is; then why would why would I be having black specks in my ice then? And its only one ice cube at that, It's like the section where the certain cube is coming from has chipped paint from it. There is no pump of any sort in our house IE: sump pumps. Nor are there any kinds of drillings or any water work being performed at this time by the city in the neighborhood either. I thought it might just be plain old calcium deposits. But I haven't been able to find any one who knows anything about this stuff to tell me if I am going about it in the correct way. I certainly don't want to pay mega-bucks for someone to come out to the house and swab the inside of the ice maker with LCR, then tell me to let it run about three to four days without digesting any of the ice cubes or we could get very sick so that and then charge me $75.00 you know what I mean?

I have the same problem and haven't solved it yet. I have a brand new water heater. A retired carpenter/contractor (47 years) posted this, saying that he knew what it was right away. He said it was the deep well pump. (I do have a well). The seal in it had broke and was leaking oil into the water. Every time the pump would come on it would stir up the tiny bit of oil, enough to make it look like a barrel. I haven't had mine checked yet, but it certainly makes sense to me.

Have cleaned rotary arms etc but still getting black specks insie cups and glasses. Is it safe to use a small amount of baking powdwer in the machine and then run it through a washing cycle (empty)?

Yes, you can use baking soda, I use it at work especially on the models with plastic tubs.
The black specks may be rust or a shutoff valve that is failing. (The water supply lines).

Hi, It sounds like maybe the house sat vacant for a long period of time.

The black specks can be from several sources but these are the 3 most common:

1. The internal and back of the fridge plastic tubing used to route the water from the water valve to the icemaker

a. If water sat in the tubing for months and there was decay of the water quality then the black gunk can build up in the plastic lines. You can clean the ice maker supply line on the back of the unit with bleached water after you gently pull the upper part of the hose from the fitting and unhook the lower part of the plastic hose from the water valve. Wear rubber gloves and be prepaired for bleached water drips. Just make sure you purge the line with fresh water after bleaching and then reconnect it on BOTH ends. I know it is not easy to get water into that tiny little hole.

Usually the water is turned off and the water line is disconnected on a refrigerator that is to sit idle of a long time and the water will drain back and out of the interan water lines of the unit.

2. It can be from plumbing that sat unused for a long period of time.

a. You can buy an in-line water filter usually for under $25.00 and install it on the 1/4 input line to your fridge (The filter kits come with installation instructions) An easy job for anyone that can follow an instruction sheet.

b. If you do install an in-line water filter purge the water line in a bucket by turning on the supply valve and fill the bucket about half full of water then turn off the water in install the filter.

3. The diaphram in the water vavle dried up when the unit was idle. The diaphram rubber could have broke down from being dry and is now showing up in your ice as black specs.

I would not give up on the unit yet.... It sounds like with a little persistence it will be fine.

Whirlpool ice dispenser not working, but water is

There are three common problems with icemakers:

There's no ice
Small or too few ice cubes
Specks in the cubes
Note: If your repair problem isn't listed, click here to email the RepairGuru. He will give you the help you need.

There's no ice If your ice maker has stopped producing ice completely, check these, in this order:

  • It may be turned off. Look for the wire along the right side of the ice maker that looks a bit like a coat hanger. If the wire is in the raised position, the ice maker is turned off. If so, try one of these:

    • If your ice maker has a small red plastic lever, lower it to lower the wire.

    • If there's no plastic lever, simply lower the wire.

    In either case, the ice maker should begin producing ice again. Also make sure that the temperature is 8 degrees Fahrenheit or lower. If the freezer is too warm, the ice maker won't cycle properly.

  • The ice maker fill tube may be blocked with ice. If so, melt the blockage using a hair dryer-but be careful to not melt any plastic parts! Also replace the water shut-off valve or water-inlet valve, or both, if necessary.

  • The ice maker head assembly may have broken parts. Look to see if the gears are broken. Check to see if the small plastic arms that rest against the ice rake are broken. If the ice maker head assembly is modular and you've found broken parts, you can just replace it.

Small or too few ice cubes If the ice maker is producing ice poorly--making small cubes or too few cubes--you probably have a clogged water line, a defective water-inlet valve, or a defective ice maker mold thermostat that isn't cycling properly. Check these:

  • The water line that's attached to the back of the refrigerator. Make sure you have good water flow. If the flow is poor, repair, clean, or replace the tubing or the shut-off valve that supplies the water.

  • The water-inlet valve. Replace it if it has failed.

  • Check the freezer temperature. If should be 8 degrees Fahrenheit or lower. If the freezer is too warm, the ice maker won't cycle properly.

  • The ice maker mold thermostat. Make sure that it's cycling properly.

Specks in the cubes If you find black or gray specks in your ice cubes, have a look at the ice cube tray. If the protective coating is peeling away, the most economical solution is to completely replace the ice maker.

Did you try cleaning the lense? You'll have to pull all the toners and open the little door below and wipe with a clean lint free cloth in ONE direction.
