6. After the backwashing is complete, remove the portafilter and silica plate. Press the manual water output button to allow residual cleaning solution in the brewing system to flow out. Turn water off after flushing for about one minute or until the water is clear and clean.

a. During reverse flushing, remove and wash the copper plate and filter element with clean tap water. Wipe with soft cloth.
b. If process is unable to sufficiently clean the plate and filter element, immerse the components overnight in a mild cleaning solution of 3 tsp detergent in 1 pint hot water.

1. Rinse and reassemble components before restarting the espresso machine.

Portafilter and Filter Basket

1. Rinse the portafilter with hot water after each brewing cycle to dissolve residual oils in the filter basket and outlet nozzle and prevent oils from affecting the quality of coffee.
2. Disassemble the portafilter and place all parts in cleaning solution (3tsp of detergent in 1 pint hot water) for 24 hours to dissolve residual coffee oils. DO NOT immerse plastic portion in cleaning solution to avoid deterioration.
3. Rinse all components with clean water. Wipe with a soft, clean cloth only.

Steam Tube

1. After making steamed milk, use a slightly moistened soft cloth to wipe steam tube.
2. After wiping, release a steam burst through the tube to remove any residual milk remaining in the nozzle.
3. If hardened milk residuals remain in the steam tube, disassemble and immerse tube in hot water for about 20 minutes to soften. Reassemble and repeat step (1).

Estella CAFFE

Water Tray and Discharge Trough

1. Turn off the machine and remove the water tray. Wash thoroughly with cleaning solution and rinse with water.
2. After removing the water tray, wipe and remove sediments in the discharge trough with a wet cloth or napkin and wash with hot water to clear the discharge tube.
3. If water does not discharge properly, place a teaspoon of detergent into the discharge trough and flush with hot water to dissolve residual oils in the tube.
4. After the discharge trough is cleaned and the tray is dry, reassemble the water tray.

Boiler

To extend the serviceable life of your unit's boiler, or when you expect the machine to sit idle for a long period of time:

1. Turn power to the machine OFF.
2. Open the steam output to discharge pressure in the boiler. Continue until the pressure gauge reading falls to zero and steam discharge ends.
3. Once complete, empty and clean the water tray and discharge trough.

Leave the steam output setting open following steam discharge. Steam output should remain open until after the machine is turned back on and hot water begins dripping from the steam tube.

Contact a service professional to delime the unit every 6 months.

Filter

The manufacturer recommends replacing the filter element on the resin exchange filter after processing 53 gallons of water (about 3,000 – 4,000 cups of coffee). This schedule can be expected to vary based on the quality of water used in your machine.
