Finding Your Leak’s Source
Before you can fix anything, you need to know exactly where that water’s coming from. Here’s how to track it down:

- Dry the entire area completely with towels
- Place paper towels around these common leak points:
- Water supply connection at the wall
- Water line connection at the refrigerator
- Along the entire water supply line
- Under the ice maker unit itself
- Around the water filter housing
- In the drain pan beneath the fridge
- Wait 30 minutes and check which paper towels get wet first – that’s your leak source

FAQs
Test your water pressure – it should be between 20-120 PSI. Too high pressure can force connections loose and cause leaks. Install a pressure reducer if needed.
This usually indicates a problem with the water fill system – either a faulty water inlet valve or misaligned fill tube. Check both during an ice-making cycle.
A small amount of water during defrost is normal, but it should drain properly. If you’re seeing pooling, your drain system likely needs cleaning.
Plastic water lines should be replaced every 5 years, while braided stainless steel lines can last 10+ years. Replace them sooner if you notice any wear.
