A puddle under the washer is more than an annoyance — it can damage your floor, subfloor, and the room below. The good news: most washer leaks come from one of six common sources, and five of them are DIY fixes. Here's how to find the leak and fix it.
The braided or rubber hoses that connect the washer to the water shut-off valves are the most common leak source. They crack at the connections or develop small holes from vibration and mineral buildup.
Find it: Turn on the water. Look at both supply hose connections (at the wall and at the washer). Check for drips, mineral deposits, or a damp patch on the floor directly below the hose.
Fix: Replace the supply lines ($10-20 each). Use braided stainless steel lines, not rubber. Tighten the connections finger-tight plus a quarter turn — not wrench-tight, which can crack the fitting.
The rubber gasket around the front-load door has a seam where it meets the tub. Over time, the gasket cracks, tears, or the seam separates. Water leaks from the front of the machine during the wash and rinse cycles.
Find it: Look inside the door gasket. Feel for cracks. Check the seam where the gasket meets the tub. Look for dampness on the front panel below the door.
Fix: Clean the gasket and the seam. If the gasket is cracked or the seam is separated, replace the door seal assembly ($30-60). This is a moderate DIY job — you'll need to remove the door and the front panel.
The drain hose connects the washer to the standpipe or wall drain. If the connection is loose, the hose has a hole, or the standpipe is too short (the hose end is below the water level in the standpipe), water leaks at the back of the machine.
Find it: Look behind the washer. Check the drain hose connection at the standpipe. Check the hose for cracks. Make sure the hose end is at least 30 inches above the floor and not submerged in the standpipe.
Fix: Reconnect or replace the drain hose ($10-20). Add a hose clamp at the standpipe connection. If the standpipe is too short, install an extension.
The inner tub is suspended in the outer tub by a bearing and seal assembly. When the bearings wear, the seal fails, and water leaks from the bottom of the machine. This is accompanied by a grinding or squealing noise during spin.
Find it: If the leak is at the bottom center of the machine and you hear a grinding noise during spin, it's the bearing assembly. Check for dampness on the floor directly below the center of the washer.
Fix: Replace the bearing and seal assembly ($50-150 part, $300-500 with labor). This is a major repair — it involves removing the entire tub assembly. For most washers, this is the "repair vs replace" tipping point.
The water inlet valve sits at the back of the washer and controls water flow into the machine. If the valve body cracks or the internal seal fails, water leaks from the back of the machine during the fill cycle.
Find it: Look at the back of the washer during the fill cycle. If you see a drip or stream from the valve body (not the supply lines), the inlet valve is leaking.
Fix: Replace the water inlet valve ($20-40). Disconnect the supply lines and the electrical connector. Replace and reconnect.
If the leak is at the top front of the machine and only happens during the wash cycle, the detergent dispenser may be cracked or the lid isn't sealing properly. Excess suds can also overflow from the dispenser.
Find it: Check the dispenser tray and the lid. Look for cracks. Make sure you're using the correct amount of detergent — too many suds cause overflow.
Fix: Replace the dispenser ($10-20). Use HE detergent for high-efficiency machines. Don't overfill the dispenser.
