Tristar Low Steam Pressure / Wet Steam

Steam wand sprays water instead of dry steam, or pressure is very low.

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

Insufficient boiler temperature, Scale in boiler, Steam thermostat cutting off early, Partially blocked steam tip

Safety first: Use caution around hot steam and water.

Preheat longer: Allow the Tristar machine extra time in steam mode before opening the steam valve.
Clean steam tip: Remove and clean the wand tip thoroughly.
Descale: Run a descaling cycle to improve boiler performance.

Note: If steam remains weak, the steam thermostat or boiler heater may be underperforming and require service.
