Sterra S — Water Leakage from the MachineUpdated an hour ago
How to Fix a Water Leak on Your Sterra S
If you notice water pooling around or leaking from your Sterra S, do not panic. Follow this quick guide to locate the source of the leak, stop the water flow, and determine if it can be fixed instantly or requires a technician visit.
FIRST STEP: Isolate the Water Supply
Before inspecting the machine, shut down incoming water to prevent pooling:
Locate the metal adapter valve under your kitchen sink or near your main water connection.
Turn the valve handle 90 degrees so it sits perpendicular (at a right angle) to the water line. This completely shuts off water flow to the purifier.
Select Your Leak Location to Resolve the Issue
| Leak Location | What it Means | Immediate Action Required |
| Around the Internal Filter | The filter cartridge isn't fully locked or sealed into its mounting slot. | Open your filter side-panel door. Twist the leaking filter counter-clockwise to remove it, check that the rubber sealing rings are straight, reinsert it, and twist it firmly clockwise until it locks completely into place. |
| From the Back Panel (Droplets/Sweating) | This is harmless condensation caused by a dusty rear filter blocking airflow, making the compressor work too hard in a humid kitchen. | 1. Slide out the rear mesh dust filter, wash it under running water, and dry it completely. 2. Turn off the Cold Water function before bed using your front panel settings, and turn it back on in the morning. Monitor for 1 week to see if the moisture stops. |
| From the Front Spout or Underneath | Internal water tanks or dispensing solenoids have suffered a pressure failure. | Keep your main under-sink water valve turned OFF, unplug the unit from the wall, and click the link below to connect with a live agent for a priority repair ticket. |
| From the Thin Tubing / Supply Line | The external plumbing lines connecting your sink pipes to the machine have a loose fitting. | Keep your main under-sink water valve turned OFF and connect with us below so we can dispatch our original installation technician to re-secure your plumbing line. |
