A common issue for many refrigerator brands is water leaking from the fridge. This problem can be triggered by smaller issues, such as a clogged drain line due to food debris or excessive ice buildup. In some cases, simply defrosting the refrigerator periodically might suffice. However, this often doesn’t fully resolve the issue, and professional repair, thorough cleaning, or even replacement of certain parts may be necessary. In most cases, our technicians carry the necessary parts, allowing them to complete repairs on the same day, typically within one to two hours, in 90% of situations.

Main Issues When Fridge or Freezer Is Leaking Water
Description and Troubleshooting of Problems
Clogged Drain Line
When a refrigerator defrosts, which happens automatically a few times a week, water flows into the drain line. If the drain line is clogged, water begins to freeze, creating ice that further blocks drainage, causing water to leak into the refrigerator and eventually onto the floor. If you notice ice at the bottom of your refrigerator, it’s likely due to a clogged drain. The drain becomes blocked over time due to buildup, small debris, food particles, or packaging that can get in. To resolve this issue, start by defrosting the system and checking all elements of the defrosting system, such as the defrost thermostat, temperature sensors, and heating element. Then, defrost and clean the drain line. If all electronic components are functioning correctly, in most cases, defrosting and cleaning the drain line will be enough to solve the problem.


Malfunctioning Defrosting System
If the defrosting system isn’t working correctly, it can also lead to ice buildup inside the refrigerator, causing water to leak onto the floor. This is a common issue for all refrigerators, regardless of the brand (here you can mention specific refrigerator brands). A faulty defrost thermostat or heating element is often the culprit behind defrosting system problems. Our technicians can quickly inspect all components for any malfunctions, replace them if necessary, and defrost your refrigerator.

Damaged Water Line
The water line connected to the water dispenser or ice maker may be damaged, or there might be a loose connection at the fittings. In this case, water might leak slowly when you use the water dispenser or when the ice maker is operating. This issue can occur due to high water pressure in the system or if the refrigerator has been moved. To resolve this problem, a detailed inspection is necessary to locate the source of the leak. If the water line is damaged, it should be replaced. Often, leaks occur at the connectors, which can usually be repaired.

Damaged Gasket or Door Seal
A damaged gasket on the refrigerator or freezer door can cause a water leak. When the gasket is compromised, warm air enters the refrigerator, creating condensation and ice buildup inside. This causes the door to not close properly, leading to a frozen drain line and ultimately water leaking from the refrigerator. This is a common issue across all refrigerator brands. To fix this problem, the gasket needs to be replaced, and the system should be fully defrosted. This includes not only the interior of the refrigerator but also the coil and drain line, as these areas often freeze up as well after the initial problem.
Leaking Water Valve
Water valve leaks can stem from several issues, with common causes being poor connections in the tubing or a faulty seal within the valve itself. Leaks may also occur due to sudden increases in water pressure within the system. Depending on the specific issue with the water valve, you might notice constant water leakage or intermittent leaks a few times a day with only a small amount of water. After a thorough diagnosis to determine the leak source, the problem can be addressed. This might involve replacing the water valve if it is the root cause or repairing the tubing connections to the valve. Additionally, checking the water pressure is crucial; excessive pressure can lead to leaks and improper functioning of the refrigerator’s water system. High water pressure can also cause leaks through the water dispenser or ice maker.

I was confused about why my fridge was leaking water, but after reading your article, I’m pretty sure I need a gasket replacement. Do you have a new gasket for the Sub-Zero BI-36U? Will you be able to replace it on the first visit?
Good day! That’s a specialized part, but we can source and replace it for you. However, before proceeding, let our technician confirm that it’s the actual cause of the issue. If it is, we’ll replace it the same day. Feel free to reach out!
We often leave for extended periods, so we turn off the refrigerator every time, usually for 2-3 weeks in a row. Recently, we’ve started noticing that the refrigerator is leaking. The fridge is only 1.5 years old. Could frequent shutdowns be damaging the fridge?
Frequent shutdowns of your refrigerator for long periods shouldn’t typically cause leaks, but it can lead to issues like mold or condensation, which may result in leaks when turned back on. Also, turning it off for extended periods can affect components like the defrosting system, seals, or water line. Therefore, it’s better not to turn off the refrigerator but to keep it in energy-saving mode. This minimizes electricity costs while maintaining the proper temperature for the correct functioning of all systems.
My fridge leaks water only when I open the freezer door. Could this be caused by a faulty door seal or something else?
If your fridge leaks water when you open the freezer door, it could be due to a faulty door seal, causing condensation and ice buildup. It might also be a clogged drain line or a malfunctioning defrost system. A technician can help diagnose and fix the issue.
