Possible Causes

Missing or damaged internal seals, Cracked top cover allowing steam path, Loose hose connection venting steam, Overfilled reservoir causing overflow

How to Fix / Troubleshooting

Safety: Unplug the unit and allow it to dry completely before further use.

  • Check fill level: Do not exceed the maximum fill line on the reservoir; overfilling can cause internal overflow.
  • Inspect seals and hoses: Open the housing and look for loose hose connections or missing grommets that could allow steam to escape into the base.
  • Replace damaged seals: Install new grommets or seals where hoses pass through panels.
  • Check top cover: Replace the top cover if it is cracked or warped and no longer directs steam correctly.
  • Dry thoroughly: Allow all internal components to dry for at least 24 hours before reassembly and testing.
