Sterra 7 — E13 Cold and Self-Care Icons Blinking — Cooling Module OverheatUpdated an hour ago
Your Sterra 7 features built-in safety sensors that monitor internal temperatures. If the cooling component gets too hot, usually due to restricted airflow, trapped dust, or high ambient room temperatures, the machine will temporarily lock down to protect itself.
Follow this guide to safely cool down, clean, and reset your system.
Step 1: Immediate Safety Shutoff & Cooldown
To protect the cooling compressor, the machine needs to be completely powered down to drop its internal temperature.
Unplug the machine: Turn off the main power switch at the back/side of the Sterra 7, then completely unplug the power cord from the wall outlet.
Check the clearance: Make sure there is at least 15–20 cm of open space on all sides of the unit. Ensure no vents are blocked by walls, cabinets, or clutter.
Check the surrounding environment: Ensure your Sterra 7 is not placed near heat-producing appliances like ovens, kettles, microwaves, or refrigerator exhausts.
⏱️ Important: Leave the machine completely unplugged for 2 full hours. The internal cooling components cannot reset until they have cooled down entirely.
Step 2: Clean the Rear Dust Filter
While waiting for the unit to cool, clean the dust filter to ensure maximum airflow when you turn it back on.
Locate the mesh dust filter at the back of your Sterra 7 and gently slide it out.
Rinse the filter thoroughly under cool, running water to clear out any trapped dust or pet hair.
Let the filter dry completely before sliding it back into the machine. Never reinstall a damp filter.
Step 3: Restart & System Flush (15 Minutes)
Once 2 hours have passed and your dust filter is completely dry, you can restart your system.
Plug the Sterra 7 back into the wall and turn the main power switch ON.
Do not touch any buttons. The machine will automatically begin an internal system flush.
The main dispense button will pulse slowly in a "breathing" light pattern.
Wait approximately 15 minutes for the cycle to complete. When all the lights turn completely off, your cooling system is reset and ready to use.
Step 4: Prevent Future Overheating (Water Flow Checks)
If your machine cooled down successfully but you want to prevent it from happening again, restricted water flow can sometimes cause the system to overwork and overheat. Check the following:
Check Your Water Filters
When did you last change your filters? If it has been more than 4–6 months, a clogged water filter might be restricting flow and causing the motor to work too hard. We highly recommend replacing your filters.
Check the Under-Sink Source Valve
If your filters are new but your water flow feels unusually slow, your under-sink intake valve might be partially blocked or restricted.
