This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Loose thermoblock connection, Cracked steam hose, Failed O‑ring on heater outlet, Overpressure valve venting steam

Safety: Unplug immediately; steam can cause burns.

Do not continue use: Operating with a steam leak is dangerous.
Visual check: After cooling, inspect for visible cracks or melted plastic near the top vents.
Service required: Internal steam leaks must be repaired by replacing hoses or seals inside the L’OR machine. This is not a user‑serviceable repair.
