of the PID controller.

modes. Operating the machine in 20 amp mode on a 15 amp circuit could pose a
fire hazard and should never be done. Chris Coffee Service Inc., CaffeTech

Regular Maintenance
Back flushing is a vital maintenance procedure you must follow to help keep your
machine running flawlessly for years to come. There are two types of back flushing:
one with plain water, and the other with espresso machine cleaner.
Plain water back flushing :
Should be done at least once a week, however if you are so inclined, feel free to
back flush with plain water as often as you like.
To back flush, you use the portafilter’s blank insert (the round stainless steel disk
without holes). To remove your single or double portafilter basket, use the blank
portafilter insert. Turn it upside down and use its edge to pry the basket out of one
of your portafilters. (If you always make double espressos, you may choose to keep
the blank portafilter insert in your other portafilter so you always have one ready.)
Next, place the blank insert into the portafilter and slap it hard with the palm of your
hand to secure it in place. To perform a plain water back flush, place the portafilter
into the group and snug it firmly. Next, raise the brew lever all the way up for 15
seconds, and then lower it all the way down. Water will forcefully discharge out of
the bottom of the group into the drip tray; this is normal. Repeat three to five times.
Back flushing with espresso machine cleaner
is the same procedure as above with a few minor differences. The first difference is
back flushing with espresso machine cleaner only needs to be done approximately
once a month or every 35-50 espressos. I don't recommend back flushing with
cleaner more often than once every three weeks since overuse will remove oils that
lubricate the brew lever and valves. You can water back flush as often as you
prefer. For cleaning supplies see the following link:
