How to Fix / Troubleshooting

User checks:

  • Remove the water tank, fill it, and place it on a sink or towel to see if it leaks when not on the machine.
  • Inspect the outlet valve and rubber seal for cracks or deformation.
  • Ensure the tank is seated correctly on the machine and that the base seal is clean.

Replace the water tank if it leaks off the machine or if the outlet valve is damaged. If the leak is at the machine-side seal, replace the tank base seal on the machine.
