Possible Causes

Damaged or worn tank valve, Debris stuck in valve seat, Tank overpressurized or overfilled, Tank body cracked

How to Fix / Troubleshooting

Safety first: Remove the water tank immediately and dry any water around the dock and robot. Do not allow water to enter electrical contacts.

Inspect tank:

  • Check the tank for visible cracks or damage.
  • Inspect the valve area for debris and clean gently.

Test off-robot:

  • Fill the tank and place it on a sink or waterproof surface, valve side down, for 10–15 minutes to see if it drips.

Replace if leaking:

  • If the tank leaks when off the robot, replace the water tank with a new Proscenic-compatible unit.

Advanced: If water has entered the robot body, allow it to dry completely for at least 48 hours before use and have it inspected if any abnormal behavior occurs.
