Don't despair when you discover that your washing machine is leaking. Several things can cause it to leak while filling with water, and many of them only require minor repairs. To diagnose the problem, try to pinpoint the leak source. After you've identified the problem, you can take action to remedy the issue, so no further leaks occur.
Split Water Supply Hose
One of the first places to check for a leak is the washer's water supply hoses. Most washing machines have one hose for hot water and another hose for cold. The hoses connect to the valve on the laundry room wall and to the washer. Water flows through the hoses into the machine when you turn your washer on. Run your hand over each hose to feel for any wetness. If you feel moisture, inspect each hose for possible cracks. Replace broken hoses.
Faulty Tub Seal
Between the outer tub and the washer transmission is a tub seal. The seal protects the transmission from becoming wet when the tub fills with water. However, the seal is liable to break as a washer ages, and when it does, water leaks from the washer when it fills. Check below the washer in the vicinity of the outer washtub for signs of leakage. Contact a washing machine repair specialist if you suspect the seal has broken. Unfortunately, replacement involves an extensive repair.
Defective Water Level Switch
The water level switch alerts the control panel when water fills to a certain level in the washtub to close the water inlet valve, so filling stops. However, if the switch breaks, the control panel has no way of knowing how much water is in the washtub and never closes the water inlet valve. As a result, water continues to flow into the washtub until it overflows and leaks from the washer door. Shut off the main water supply valves to stop water from entering the washer. Contact a washing machine repair specialist to replace the broken component.
Corroded Water Inlet Valve
The water inlet valve is prone to corrosion and rust from mineral deposits in your water supply. Over time, the deterioration can impact the valve's function and cause it to stick. If it becomes stuck while it's open, the water never stops flowing into the washer when the machine fills, even after its instructed to close by the control panel, and consequently water overflows the machine. Immediately close the water supply valves to stop water from entering the washing machine. Consult a washing machine specialist to switch the valve out with a new one.
