Replace the Upper Piston O-Ring
The upper piston o-ring must be replaced every 5,000 drinks.
When the message REPLACE O-RING is displayed, follow the
procedure below.
1. Open the machine doors.
2. Use the brush provided in the cleaning kit to clean the
upper piston and o-ring area.
3. To remove the o-ring: press both sides of the o-ring
with your index fingers and gently pull the o-ring
towards the front of the machine. You should see a
portion of the o-ring pull away from the o-ring groove.
Using your thumb, press down on the exposed edge and
roll the o-ring down and off of the upper piston.
NOTE: If it is difficult to use your thumb to remove the
o-ring, you can use a small flathead screwdriver to
remove the o-ring. If you use a flathead screwdriver,
very gently insert it gently between the o-ring and the
upper piston; once the head of the screwdriver is under
the o-ring, gently run it under the o-ring to loosen (it is
only necessary to loosen half of the o-ring).
WARNING: Be very careful not to damage the piston.
