Possible Causes

Cracked water tank, Damaged tank outlet O-ring, Loose internal silicone hose, Failed boiler or thermoblock seal

How to Fix / Troubleshooting

Safety first: Unplug the machine immediately if you see water near electrical parts or under the machine.

User-level checks:

  • Inspect water tank: Remove the tank, fill it over a sink, and check for cracks or leaks. Inspect the outlet valve and O-ring for damage.
  • Check seating: Reinsert the tank firmly to ensure a proper seal.
  • Observe leak source: Place a dry paper towel under the machine and run a rinse cycle to see where water appears.

When to call a technician: If water appears from inside the chassis or from the back, an internal hose, fitting, or boiler seal is likely leaking and must be repaired by a professional.
