We've now got some descaler working its magic in the path leading to the boilers. (Unless you skipped the previous step) Now we need to get inside the boilers to clean them.
-
Unplug your machine.
-
On the brew boiler (in front), there are two probe ports towards the front of the machine with blue wires attached. On the steam boiler (the other one), there are 3 probes. Take a picture of these.
-
Remove the wires on these probes. You should be able to use your fingers, but you might gently use the pliers instead. Remember the wire order.
-
Remove the clips retaining the hoses. Simply insert your needle nose pliers into the little loop and work them out, careful not to drop them.
-
Gently pull the probes out, noting that the short probe on the steam boiler goes in the port on the right. You'll want to scrub these or soak the rods in descaler and set them aside for later.
-
It's siphon time! Place a container (anything around 2 liters or more) below the level of your machine. I simply put a big measuring cup on a chair.
-
Insert one end of your tubing into one of the boiler ports and slide it down until you feel it reach the bottom. Start suction on the other end of the hose until you see the water close to your mouth. Place your finger over the end of the hose to prevent the water draining and drop the end of the hose into the container and let go.
