MAINTENANCE

 

DAILY MAINTENANCE

 

Daily cleaning and maintenance procedures are essential for maintaining optimum performance of your es-
presso machine. The following are procedures to be carried out on a daily basis:

 

Backflushing: 

 

This process forces water through the inlet tube and drain system. This should be performed on EACH brew 
group daily. 

 

1. Replace the filter basket with the 

‘

blind

’ 

basket, which has no filter holes.

 

2. Engage the portafilter, then follow the instructions on page 21 to use the auto backflush function. 

 

3. When using an approved espresso industry detergent during backflushing, follow the manufacturer

’

s in-

structions. It is extremely important to thoroughly rinse the blind filter basket and repeat backflushing sever-
al times with clean water to clear the system of any detergent residue. 

Failure to rinse after using detergent 

can cause valve problems and bad flavor.

 

Note: 

NEVER remove the diffuser screen and screw when backflushing. Backflushing without the screen can 

cause detergent and other unwanted particles to enter the brew system and can lead to valve and flow prob-
lems. Remove and clean the screen and screw after backflushing is complete. Do not forget to reinstall.

 

General Machine Cleaning:

 

1. Clean the surface of the machine using a soft damp cloth. Avoid using abrasive cleaners or cleansing pads. 
Take extra care on the mirror finish stainless steel surfaces. A 

“

micro

-

fiber

” 

towel is recommended to avoid 

scratches.

 

2. Make sure the steam wands and tips are free of milk build

-

up. It is always best to clean the steam wand 

and tip after each use by purging and wiping with a damp cloth. Approved espresso industry cleaners can be 
used to dissolve milk build

-

up. Tips can be removed to soak. Deep cleaning of the wands and tips should be 

carried out periodically. 

 

3. The drip tray, drip tray grates, and portafilters should be removed and cleaned every day. If you clean the 
portafilters in the dishwasher, first remove the filter baskets and springs before washing. Do not place wood-
en handled portafilters in the dishwasher. Wood should be cleaned using wood

-

safe cleaning procedures.

 

Wood and Water

 

Wood accents should be wiped down with a damp rag to clean. Do not soak or soap wood. 
Never place wood products in the dishwasher! Treat wood with food safe oil or wax quar-
terly or more often if the surface appears dry.
