enough cold water to reach the proper ratio. Once the solution is cool, use it to fill the

water reservoir at least ½ full.

10. Plug the machine in and only turn the power switch to Position I.

Allow the boiler to

fill. Do not continue to the next step until the pump stops. Please note: Some of the

earlier versions had a time-out function which will disengage power to the autofill

box after 1 minute. If that is the case in your unit, and the autofill shuts off on its

own after 1 minute, turn the power switch to 0 and the back to I and it will

reactivate the autofill. This safety function will continue engaging throughout the

whole process, so keep in mind that you’ll have to reactivate the autofill when

necessary.

WARNING: In many of the following steps, such as when pumping descaler through the

grouphead and removing the hoses from the water tank, splashing acid can create a safety

hazard. Gloves, eye protection, and work-area protection are required.

11. Place a suitable container under the grouphead, turn on the brew function, and run about

8 ounces of descaling solution through the grouphead. This also ensures that the

thermosyphon pipes, the heat exchanger, and the internal components of the grouphead

will be descaled.

12. Snap the blind filter into the portafilter handle and simulate backflushing the machine.

Turn on the brew function and allow it to run for about 10 seconds after the pressure

reaches its peak. This will force descaler through the over-pressure relief valve. You

will see the liquid flowing back into the reservoir through the secondary hose. When

that takes place, turn the machine to 0 and UNPLUG the power cord. Leave the hoses in

place and move the reservoir off to the side of the machine and lift off the reservoir

platform.

13. Remove the two Phillips head screws holding the top of the divider panel and swing it

back and off the machine. Take care not to stress the wires attached to the water-level

microswitch which is attached to the panel.

14. Remove the water level sensor wire

by loosening the screw inside the

plastic housing shown in the

picture. Leave it disconnected for

now. This will fool the boiler into

thinking that it is low on water and

needs to be refilled. Set the wire off

to the side where it cannot

accidentally connect with any metal

parts.
