Cracked water tank, Damaged tank bottom seal, Loose or cracked internal silicone hose, Failed O-ring on heater or pump connection
How to Fix / Troubleshooting
Safety first: Unplug the machine immediately and remove it from power if you see water leaking. Do not operate a leaking appliance.
- Inspect water tank: Remove the tank, dry it, fill it over a sink, and check for cracks or leaks from seams or the bottom valve.
- Check tank seating area: Dry the base and observe if water appears around the tank connection when the tank is reinstalled.
- Do not open housing with water present: Allow the machine to dry completely before any further handling.
- If leak is internal: The issue is likely a hose, O-ring, or heater connection inside the unit. Internal repairs should be performed by a technician due to electrical shock risk.
