Periodic Maintenance

Here’s a checklist of basic long-term maintenance; each step is explained after.

WARNINGDo not immerse power cord, power plug or appliance in water
or any other liquid.

Decalcifying

After regular use, hard water can cause mineral build up in and on many of the inner functioning components, reducing the brewing flow, brewing temperature, power of the machine, and taste of the espresso. We advise decalcifying the machine every month and especially if not using the machine for an extended period, e.g., before going on vacation. Replacing the water filter every two months will reduce the need to decalcify the machine.

WARNINGThe water tank should never be removed or completely emptied
during decalcifying.
TO DECALCIFY:
  1. Remove the portafilter.

  2. Pour a 50:50 mixture of white vinegar and cold tap water into the water tank.

  3. Place a large container beneath the group head and steam wand.

  4. When the brewing temperature has been reached and all the button surrounds on the control panel have illuminated, press and hold the 1 CUP button to commence a manual pour. Release the button once half the mixture of white vinegar and water has run through the group head.

  5. Set the STEAM/HOT WATER dial to the hot water position and allow hot water to run through the hot water outlet for approximately 30 seconds. Return the dial back to the STANDBY position.

  6. Set the STEAM/HOT WATER dial to the steam position and allow steam to run through the steam wand for approximately 2 minutes. Return the dial back to the STANDBY position.

  7. If any of the mixture remains in the water tank, press and hold the 1 CUP button to commence a manual pour. Release the button once the tank is empty and nothing runs through the group head.

  8. In harder water environments, we recommend repeating this cycle.

  9. After decalcifying, remove the water tank and rinse thoroughly then refill with fresh cold water only. To rinse the machine, repeat the steps above.

Replacing the Water Filter

The provided water filter helps prevent scale build-up in and on many of the inner functioning components. Replacing the water filter every two months will reduce the need to decalcify the machine.
If you live in a hard water area, we recommend you change the water filter more frequently. The water filter should be removed if using filtered or bottled water. (Replacement water filters are available at BrevilleUSA.com.)

Remove and discard the old water filter from the filter holder; remove the new water filter from the plastic bag.

1.Soak the water filter in a cup of water for 5 minutes, then rinse under cold running water.
2.Wash the water filter holder with cold water, taking specific care to rinse the stainless steel mesh.
3.Insert the water filter into the two parts of the water filter holder.
4.Set Date Dial 2 months ahead.
5.To install the assembled water filter holder into the water tank, align the base of the water filter holder with the adapter inside the water tank. Push down to lock into place.
6.Slide the water tank back into position at the back of the machine, ensuring to push down completely to lock into place.

Cleaning Cycle

The CLEAN ME light will illuminate when a cleaning cycle is required. This is a back-flushing cycle and is separate from decalcifying. (Additional espresso cleaning tablets are available at BrevilleUSA.com.)

TO RUN THE CLEANING CYCLE:
  1. Insert the 1 CUP filter basket into the portafilter, followed by the supplied cleaning disc, followed by 1 cleaning tablet.

  2. Lock the portafilter into the group head.

  3. Place a large container beneath the group head.

  4. Ensure the water tank is filled with cold water and the drip tray is empty.

  5. Press the POWER button to turn the machine Off.

  6. While pressing the 1 CUP and 2 CUP buttons, simultaneously press the POWER button. Hold all 3 buttons together for 10 seconds.

  7. The cleaning cycle will commence and last for approximately 5 minutes. During this time, water will intermittently pour from the group head. Once complete, 3 beeps will sound.

  8. Remove the portafilter and ensure the tablet has completely dissolved. If the tablet has not dissolved, repeat until the tablet has dissolved.

Silicone Seal & Using the Allen Key

Over time, the silicone seal surrounding the shower screen will need to be replaced to ensure optimum brewing performance.

1.Press the POWER button to turn the machine Off and unplug the cord from the power outlet.
2.Carefully remove the rear water tank and drip tray, taking particular care if they are full.
3.Using a skewer or similar, clean the center of the screw of any residual coffee.

5.Once loosened, carefully remove and retain the screw, stainless steel shower screen and black dispersion plate. Make note of the side of the shower screen and dispersion plate that are facing downwards. This will make re-assembly easier. Wash the shower screen and dispersion plate in warm soapy water, then dry thoroughly.
6.bes840xl-siliconeRemove the silicone seal with your fingers or a pair of long-nose pliers. Insert the new seal, flat side first, so the ribbed side is facing you.
7.Re-insert the dispersion plate, then the shower screen, then the screw. With your fingers, turn the screw clockwise for 2-3 revolutions then insert the Allen Key to tighten until the screw is flush with the shower screen.
8.Re-insert the drip tray and rear water tank.
