If a washing machine is leaking water and leaving wet spots on the floor without leaking when it's turned on, there could be a few possible explanations:
Drainage Issue: The most common reason for this problem is a drainage issue. The washing machine might be improperly draining water during certain parts of its cycle or after the cycle is complete. This could be due to a clogged or partially blocked drain hose, a malfunctioning drain pump, or an issue with the plumbing connection.
Overloading: If the washing machine is overloaded with clothes, it can cause water to spill out during the washing or spinning cycles. When the machine is turned off, the water may not leak because there is no agitation or spinning action to force the water out.
Damaged Gasket or Seal: There could be a damaged door gasket or seal that is allowing water to seep out during the washing or spinning process but remains sealed when the machine is not in use.
Uneven Leveling: If the washing machine is not properly leveled, it might tilt or wobble during certain cycles, causing water to splash out of the machine.
Detergent or Fabric Softener Dispenser: Sometimes, leaks can be attributed to issues with the detergent or fabric softener dispenser, where water overflows or doesn't drain properly.
Hidden Leaks: It's also possible that there's a small, hidden leak that only occurs under specific conditions during a wash cycle.
To identify the specific cause of the issue, it's recommended to perform some troubleshooting steps:
Check the drain hose and drain pump for clogs or obstructions.
Inspect the door gasket or seal for any signs of damage or wear.
Ensure the washing machine is properly leveled.
Verify that the detergent and fabric softener dispensers are functioning correctly.
If none of the above steps help, consider contacting a professional appliance repair technician to diagnose and fix the problem.
Remember to always disconnect the washing machine from the power supply before attempting any inspection or repairs. If you're not familiar with appliance repair, it's best to seek the assistance of a qualified technician.
