Sub-Zero Refrigerator Leaking – Why and Solutions

The following are the most common reasons Sub-Zero refrigerators leak water and how to fix them:

1. The Drain Pan is Cracked or Overflowing

The drain is located underneath the refrigerator. It has the role of collecting the melted water produced during defrosting. If your refrigerator is leaking underneath, then this should be your first stop.

Check the pan and see if it is overflowing. If it is, take it out and empty the pan.

However, the drain pan overflowing is an abnormality. This is because the fans are meant to blow warm air over the pan and evaporate the water in it. Therefore, the pan overflowing may be a sign of a more serious problem. We advise you to consult a service technician in this case.

If the pan is not overflowing then inspect it for cracks. If any crack is found, the pan should be replaced because it cannot be repaired.

You may also check to see if the pan is properly installed as if it is not, water may spill out of it.

2. Condensate Line is Clogged

The condensate line which is also known as the defrost drain transfers melted water from defrosting to the drain pan. This line can get clogged with food particles or ice which will result in water overflowing the line and spilling out.

If ice is the cause of the clog, use a hairdryer set at the lowest degree and heat the line. Or you may simply defrost the refrigerator, read this article for how to.

You can also unclog the drain by doing the following:

i. Locate the defrost drain hole inside the refrigerator. Clean the drain hole with a piece of wet cloth.

ii. Next, put a straight thick wire, like a straighten cloth hanger inside the hole and push out the clog.

iii. Make a mixture of hot water and baking soda. And use a turkey baster to flush the mixture down the drain until you hear water running into the drain pan.

3. Leaking Water Tank Assembly

The next stop is the water tank assembly; inspect it for tears and cracks. The water tank assembly cannot be repaired so if a crack is found, replace it.

4. Water Filter is Damaged

If the leak is inside the refrigerator, then you need to check the water filter. The filter head may be damaged or the seal is torn or missing.

Remove the water filter and inspect the head. If the seal is missing or torn, the filter should be replaced.

The filter may also leak if it was not properly installed. So consult your user manual for how to install the water filter.

Also, ensure you replace your water filter every 6 months. This is because the filter gets clogged with time and 6 months is the recommended length to use the filter. Ensure you buy a filter compatible with your refrigerator model whenever you shop for filters.

Sub-Zero Wine Fridge Leaking Water –What to Check

The following parts are the most common reasons why your Sub-Zero wine fridge is leaking water:

1. Drain Pan

If your wine fridge has a self-defrosting function, then the drain pan should be checked first. The drain pan collects melted water from the evaporator coils and may be the cause of the leak if it is cracked or overflowing.

The drain pan overflowing is an indication of a more serious problem so have a repair technician take a look at your unit. You can also manually empty the pan to solve the leak.

On the other hand, the pan should be replaced you discover a crack on it.

2. Door Gasket

The door gasket keeps warm air out of the fridge and helps maintain the temperature of the fridge. When worn-out or broken, the gasket will fail at its job and moisture will build inside the fridge and then spew out of the wine fridge.

Replace the door gasket to solve this problem. A part of this article gives detailed instructions on how to replace the door gasket of a Sub-Zero refrigerator. The instructions also apply to your wine fridge door gasket.

3. Wine Fridge

Condensation can build up too much in the wine fridge. When this happens, the extra moisture will spill out from any outlet. So, check the body of the wine fridge for any puncture or damage. If any is found, have a repair technician take a look at it to see if any repairs can be made.

We however recommend that you consider replacing the unit as a crack or leak on the fridge may not be easily repaired.

Also, to prevent excess condensation in the fridge, you may keep a packet of silica to absorb excess moisture.

Sub-Zero Fridge Water Dispenser Leaking – How to Fix

Do the following fixes if your Sub-Zero refrigerator water dispenser is leaking water

1. Level the Refrigerator

Your refrigerator is supposed to be leveled so that the front part is slightly higher than the back part. This is done to maintain the proper flow of coolant and ensure proper running of the refrigerator. Hence, if not leveled properly, it may cause water to drip out of the dispenser.

To level the refrigerator, remove the kick plates and adjust the leveling legs. Turning them clockwise will raise the legs while turning them counterclockwise will lower them.

Once you are convinced the tilt is right, use a level to confirm it. And then finally put the kick plates back on.

2. Flush the Water System

When the refrigerator water filter is changed, air can enter and get trapped inside the water line. This will cause a pressure buildup that will then cause water to drip from the dispenser.

The water system has to be flushed to resolve this problem. To do this, place a bowl under the dispenser and flush about 3 gallons of water.

Ensure you flush the water system after every filter change to prevent this problem from happening again.

3. Check the Water Line

Inspect the water line connected to the dispenser, see if it is bent or has a leak or crack. If any of these is found, then the water line should be replaced.

Simply remove the line from the compressor fitting and the inlet valve and put another line in its place.

4. Check the Water Pressure

The water inlet valve requires about 20 psi to shut off properly. And so if the water pressure in your home is lower than this, the inlet valve won’t shut off as it should. Ultimately, this will result in the valve constantly dripping water.

To troubleshoot the water pressure, turn off the water supply and then remove the water line from the valve. Hold the line over a bucket and turn the water supply back on.

Observe the flow of water; if it is strong then you do not have a problem with the water pressure. A weak flow indicates a problem with the water supply or the water line. Call a repair technician to know the best course of action in this case.

Sub-Zero Refrigerator Ice Maker Leaking – What to Do

The water line connected to the ice maker may be loosely connected hence the leak. So, check the line and secure it properly to the valve.

2. Unfreeze the Water Line

The line sending water to the ice maker can get frozen and then overflow with water. The solution to this is to thaw the ice in the line. Put a hairdryer in the lowest setting and heat the tube.

However, you may have to replace your water inlet valve if this keeps happening. This is because a defective valve is the major cause of this problem. A section of this article gives detailed instructions on how to do this replacement.
