When brewing, you hear the pump but little or no water exits the spout; instead, water can be seen returning to the tank or leaking around the tank area.

Safety: Unplug the machine and remove the water tank before inspection.

• Inspect water tank: Check for cracks, especially near the bottom valve and along seams. Fill the tank and place it on a dry towel to see if it leaks.
• Check tank O-ring: Examine the rubber seal around the tank outlet. If it is flattened, cracked, or missing, replace the tank or the seal if available separately.
• Inspect inlet connector: Look at the machine's water inlet where the tank sits. Check for damaged or missing O-rings and visible cracks.
• Test after reseating: Refit the tank firmly and test with plain water. If water still bypasses to the tank area, stop using the machine.

Persistent bypass or visible leaks at the inlet indicate a failed inlet connector or internal hose, which requires disassembly and should be handled by a technician.
