How to Fix / Troubleshooting

Safety: Unplug the machine immediately when a leak is noticed. Dry any spilled water around electrical outlets.

  • Check water tank: Remove the tank and inspect for cracks or a damaged bottom seal. Replace the tank if it leaks when filled and held over a sink.
  • Inspect tank connection: Look at the tank docking area for damaged O-rings or seals. Replace worn seals.
  • Open housing: Remove covers and run a short brew or rinse cycle while observing (use extreme caution around live parts). Identify the exact leak point.
  • Repair hoses and fittings: Tighten hose clamps, reseat push-fit connectors, or replace cracked silicone hoses. If the leak is at the thermoblock, replace the affected fitting or the thermoblock if corroded.
