Water pooling under a fridge is frustrating and often worrying. We might see it as a sign of a serious breakdown, but most of the time the cause is something simple. By knowing the most common reasons, we can spot problems early and prevent bigger repairs. Our team at Quick & Pro Appliance Repair Burbank deals with these issues often, so we know how important it is to address them quickly.
Blocked Defrost Drain
Sometimes melted frost cannot drain properly because the defrost drain is clogged. As a result, the water backs up and collects at the bottom of the fridge. Food bits, dust, or even ice buildup can block the drain opening. We have seen cases where a small piece of packaging from frozen food slipped down and created a blockage.
When the water has no place to go, it flows out onto the floor. To avoid this, we should check the drain area regularly. Warm water can help melt any ice, while a pipe cleaner or a thin brush works for debris. If the drain hose behind the fridge is kinked or clogged, clearing it restores the normal flow. Our company often finds this as one of the leading causes of service calls for fridge repair Burbank.
Faulty or Dirty Water Filter
Another possible cause is the water filter. Filters that are not replaced on schedule can clog and leak. In some cases, the filter itself is fine but not fitted correctly. That loose connection lets water drip and pool underneath. We recommend changing filters as the manufacturer suggests, usually every six months.
A filter that has cracks or poor seals also needs replacement. We have also noticed that generic filters often do not fit tightly, leading to leaks. By sticking to proper replacement parts and making sure they are installed firmly, we can prevent leaks from this area. This is a simple step that saves both water and damage to flooring.
Cracked Drain Pan
Every fridge has a drain pan that collects water from defrost cycles. Normally, the water in this pan evaporates on its own with help from the compressor heat. However, if the pan has a crack, the water escapes onto the floor. Sometimes the pan also shifts out of position, leaving one side lower and causing spills.
We suggest inspecting the pan from time to time. Pull it out gently and look for any damage or signs of wear. Replacing a drain pan is straightforward, and doing so quickly prevents water from soaking into flooring or cabinets. Our team has seen cases where homeowners only discovered a cracked pan after water stains appeared on nearby walls.
Faulty Water Inlet Valve
Refrigerators with water dispensers or ice makers have a water inlet valve. This valve controls the flow of water into the fridge. If it becomes worn, cracked, or loose, water can leak down to the bottom. Hard water can also cause buildup around the valve, making it stick and drip.
We always recommend checking the connections to this valve when leaks appear. Tightening the fittings or replacing a worn valve usually solves the issue. Since the valve is directly linked to the household water line, we advise turning off the supply before making any adjustments. At Quick & Pro Appliance Repair Burbank, this is one of the most common leak sources in modern fridges.
Improper Leveling of the Fridge
Something as basic as leveling can cause leaks. A fridge that tilts forward prevents proper drainage. Instead of flowing into the drain pan, water may collect inside or leak outside. Uneven flooring or shifting over time can create this imbalance.
Adjusting the legs of the fridge so that it leans slightly backward helps the water flow as designed. We often find this is overlooked, but correcting it takes only minutes. Using a simple level tool ensures the adjustment is accurate. It is a small step that makes a noticeable difference.
Overfilled or Misaligned Ice Maker
Ice makers can be another source of leaks. When they are overfilled or misaligned, water may spill over and settle at the bottom of the fridge. A clogged ice tray or frozen water line also forces water to back up. This issue is easy to miss because it often looks like normal frost at first.
Checking the ice maker regularly keeps it in good working order. Making sure the water line is clear and the tray is positioned correctly stops unnecessary leaks. Our team has handled many service calls where the ice maker was the hidden culprit behind repeated puddles.
Door Seal Problems
When the door seal is damaged or dirty, warm air enters the fridge and causes excess condensation. That extra moisture eventually drips down to the bottom and forms a pool. Over time, the rubber gasket can crack, loosen, or warp. Even small gaps are enough to let warm air in.
Cleaning the seal with mild soap and warm water helps it stay flexible and tight. If the seal is too damaged, replacement is the only option. We recommend checking the seal by closing the door on a piece of paper. If the paper slides out easily, the seal is no longer tight. Fixing this not only prevents leaks but also saves energy.
Extra Tip: Monitoring Humidity and Load
Beyond the usual causes, we find that storing too much food at once or setting humidity drawers incorrectly can also create leaks. Overfilled drawers block airflow, leading to extra condensation. Similarly, high humidity settings in already damp environments make water build up faster. By paying attention to these details, we can avoid unnecessary water at the bottom of the fridge.
For any of these problems, professional service may be needed if the issue keeps coming back. When that happens, our team at Quick & Pro Appliance Repair Burbank is ready to step in. We handle these issues daily, so we know how to diagnose and fix them properly. If you ever need full appliance repair Burbank, our company is here to help.
Take Action Quickly
The sooner leaks are addressed, the less risk there is of water damage to floors and cabinets. Small leaks left alone can lead to mold growth and costly repairs. Simple checks such as inspecting the drain pan, filter, and seals go a long way. When the problem is not clear, it is best to let a professional take a look.

FAQ
Why is water pooling under my fridge even after cleaning the drain?
This often happens if the drain hose behind the fridge is still blocked or kinked. Checking both the front and back of the drain system is important.
How do I know if my water inlet valve is leaking?
Look for water trails or mineral deposits around the valve. A constant drip, even when the dispenser is not in use, means the valve is failing.
Can a dirty door seal really cause water leaks?
Yes. A weak seal lets warm air inside, which leads to condensation and water collecting at the bottom.
How often should I replace my fridge water filter?
Most filters should be replaced every six months, but the exact timing depends on the fridge model and how often the water is used.
Is it safe to keep using the fridge if water keeps leaking?
It is not safe. Ongoing leaks can damage flooring, cause mold, and even affect the fridge parts. Fixing the issue quickly is best.
