Sterra S — Room Icon and Volume Icons Lit on Touch PanelUpdated 2 hours ago
If your Sterra S touch panel has frozen with the Room Icon and all Volume Icons lighting up simultaneously, your machine is displaying an internal error code. This pattern appears when the purifier detects that it cannot pull in enough water or when its internal engine is working too hard to maintain proper pressure.
Follow this quick step-by-step reset process to clear the error lights and restore standard operation:
Step-by-Step System Reset Protocol
1.1. Power down the machine:System Rest.
Locate the main power switch at the back of your Sterra S and turn it OFF. Unplug it from the wall outlet. This stops the internal pump and resets the display brain.
2.2. Wash the rear dust filter:Restores internal airflow.
Slide the mesh dust filter out from the back of the purifier. Wash it thoroughly under running tap water to clear away any trapped lint or dust. Shake off excess moisture and allow it to dry completely before sliding it back into place.
3.3. Inspect your water supply valves:Fixes fluid supply restrictions.
Make sure your home's raw water supply is fully active and that the unit's supply lines aren't pinched. Ensure both water valves feeding your Sterra S are turned completely to the open position (the handles should line up straight with the tubing, not point across it).
💡 Unsure where to look? Open our Visual Valve Guide to verify your kitchen setup matches our diagram perfectly.
4.4. Re-power and initialize:Clears active error codes.
Once the filter is dry and reinserted, plug the power cord back into the wall socket and switch the machine ON. Give the system a few minutes to complete its full startup calibration. The error lights should clear, leaving the panel ready for normal use.
