CAUTION: The discarded fluid from the machine will contain some of the acid solution. In all these
steps, discard the used descaling agent according to the manufacturer’s recommendations and lo-
cal regulations. If the used de-scaling agent can be legally and safely poured down a drain, allow
the faucet to run into the sink to dilute the acid. Never re-use the spent acid.
10 Wait at least thirty minutes for the descaler to work. As much as two hours might be necessary depend-
ing on the level of hardness of your water, how long since the last descale, and how much use the machine
gets.
11 Remove the reservoir, pour any remaining unused descaler back into the original mixing container, rinse
the reservoir, wipe the outside dry, and replace it in the machine.
12 Fill the reservoir with clean water.
13 Place the vessel under the group again and pump 16 ounces (0.5 liters) of water through the group, refilling
the reservoir as necessary.
14 Discard the liquid and repeat, pumping another 16 ounces of clean water through the group.
15 Rinse and dry the vessel. Run about ten more ounces of water through the group using the brew function
into the vessel again. If the water looks clear and clean, allow that water to cool sufficiently, and smell it. If
it smells clean, pick up a drop or two (no more) on a clean, dry spoon and taste it. The water should have
no acidic taste to it at this time. If it does, repeat steps 16 and 17 and taste again. Repeat the flush-and-taste
sequence until all traces of acidic taste has been removed.
CAUTION: Most proper de-scaling agents are a form of acid which is food safe, and when present
in this highly diluted form are relatively safe to consume. Read the label of the product you are
using to be sure it is safe before sampling the discarded water. Sample only a very small amount.
16 If there is no acidic taste left in the water, the descaling procedure of the brew boiler is complete. Continue
with Part B.
B - Descaling the Steam Boiler
Since the steam boiler is a separate internal component from the brew boiler, it too must be descaled.
17 Press and hold the PID power button until the display reads “oFF.”
18 Remove the end parts from both the steam wand as well as the hot water wand.
19 Turn the power switch to “Position II.” The PID display should still show “oFF.” Allow the steam boiler
to come up to its full operating pressure.
20 When the steam boiler comes up to pressure, turn the Power Switch to “Position 0.”
21 Place the vessel under the hot water wand and open the hot water valve. Discard the collected water. If
necessary, close the valve, empty the vessel, and repeat until no more water comes from the wand.
CAUTION: Water dispensed from the hot water tap can be over 200° F. (93 c.). This can cause seri-
ous burns. Use Caution!
22 Close the hot water valve.
23 Empty the reservoir and refill it with descaling solution.
24 Be sure that the hot water and steam valves are closed.
25 Turn the power switch to “Position I.” The PID should read “oFF” at this time. If not, use the PID power
button to turn the PID to “oFF.” The pump will run as soon as the power is turned on. Allow the pump to
run until it stops on its own. Be sure to check the level in the reservoir. If it becomes necessary to refill the
reservoir with descaler, turn the power switch to “Position 0,” refill with the descaling solution, then turn the
power switch back to “Position I.” Repeat until the pump stops on its own.
26 When the pump stops, turn the power switch to “Position II.”
27 Once the steam pressure gauge indicates the normal pressure range, wait at least thirty minutes for the des-
caler to work. As much as two hours might be necessary depending on the level of hardness of your water,
how long since the last descale, and how much use the machine gets
