Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the machine immediately and do not use it until the leak is resolved. Water and electricity are dangerous together.
External checks:
- Remove and inspect the water tank for cracks, especially around the outlet valve.
- Check that the tank is seated correctly and that the tank seal is intact.
Internal inspection (advanced):
- Remove the bottom cover and look for signs of water trails, corrosion, or mineral deposits on hoses and around the heater.
- Tighten or replace hose clamps on the heater inlet/outlet and pump connections.
- Replace any silicone hose that is brittle, cracked, or swollen.
If the heater block itself is leaking (corroded or cracked), replace the entire heater assembly.
