Ice maker leaking

The error code 1F on an LG refrigerator indicates a problem with the ice maker fan. The most common cause of this error code is frost or ice buildup around the fan. If you have disconnected the water line to the ice maker, then the most likely cause of the error code is frost or ice buildup. To fix the error code 1F, you will need to defrost the ice maker fan. This can be done by following these steps: Unplug the refrigerator or turn off the circuit breaker that powers the refrigerator. Remove all food and drawers from the freezer compartment. Open the freezer door and allow the ice to melt. Once the ice has melted, use a hair dryer or heat gun to melt any remaining frost or ice around the ice maker fan. Wipe away any moisture with a clean cloth. Reassemble the freezer compartment and plug in the refrigerator or turn on the circuit breaker. If the error code 1F persists after defrosting the ice maker fan, then there may be a problem with the ice maker fan motor or the control board. In this case, it is best to contact a qualified technician for assistance. Here are some tips to prevent the error code 1F from coming back: Keep the freezer door closed as much as possible to minimize air circulation. Defrost the refrigerator regularly, even if the ice maker is not in use. Clean the ice maker coils regularly to prevent frost buildup. If you live in an area with hard water, consider using a water softener to reduce the amount of minerals in the water that can contribute to frost buildup. By following these tips, you can help to prevent the error code 1F from coming back and keep your refrigerator ice maker working properly.

2 causes for this problem. one, the drain was in fact plugged up. Two, if the machine has an icemaker, the fill hose from the water valve to the ice maker is leaking, causing water to leak and then freeze in the bottom of the freezer.

Check two things.

1: see if you have ice buildup in the water inlet tube above ice maker, if you do chance are the water valve is bad, if not,

2: see if you have icicles hanging from bottom of ice maker, if you do you have a bad ice maker.

Either way, will need full model number and serial number both to get you the right part numbers for parts.

If it overfills and drips, look for an adjustment behind the plastic endcover with a +/- on it. - is less water.

If it continuously drips, replace the water inlet valve on the back where the house water supply comes in.
The water inlet valve on the back of the unit where the water supply comes in can have a slow leak and will cause ice to buildup and block the fill tube. Disconnect the ice maker line from the valve and watch to see if it has a slow drip. It doesn’t take much to eventually block the fill tube.
