Step-by-step troubleshooting
Check Drain Hose
Do: Inspect the drain hose for cracks, kinks, or loose connections.
Observe: Look for visible damage or water pooling around the hose.
Means: A damaged hose is the likely cause of the leak.
Next: Replace the drain hose if damaged.
Inspect Pump
Do: Locate the pump and check for leaks or clogs.
Observe: Water dripping from the pump or debris blocking the impeller.
Means: A faulty or clogged pump is causing the leak.
Next: Clean the pump or replace it if damaged.
Check Level
Do: Ensure the washer is level on the floor.
Observe: Uneven leveling can cause water to pool and leak.
Means: An unlevel washer may lead to leaks during operation.
Next: Adjust the feet to level the washer.
Examine Hoses
Do: Check inlet hoses for cracks or loose connections.
Observe: Water dripping from the inlet hoses or connections.
Means: A faulty inlet hose is causing the leak.
Next: Replace the inlet hose if damaged.
Inspect Tub Seal
Do: Look for damage or wear on the tub seal.
Observe: Water leaking from the tub area or around the drum.
Means: A damaged tub seal is the source of the leak.
Next: Replace the tub seal if damaged.
Check for Overflows
Do: Ensure the washer is not overfilled.
Observe: Water overflowing from the top or sides of the washer.
Means: Overfilling can cause water to leak from the bottom.
Next: Reduce the load size and redistribute items evenly.
