Question 1

Why doesn't the water tank of the CA-106 Smart come out?

Accepted Answer

If the water tank does not come out, it is usually because the locking clips are not fully unlocked. Here’s how to proceed:

Steps to remove the stuck tank

Turn off and unplug the device before any handling
Locate the two fastening clips located on the sides of the tank
Rotate the clips from the vertical position to the horizontal position - this rotation unlocks the tank
Ensure the clips are in the horizontal position before pulling
Gently pull the tank until halfway out, then remove it completely

Tip: If the clips resist slightly, do not force them. Just make sure they are fully in the horizontal position (parallel to the device). The tank should slide out easily once unlocked.

Reinstallation: When putting the tank back in place, rotate the clips back to the vertical position and ensure they are securely locked to avoid leaks. The tank has a capacity of 5.5 liters.
