Backflush Procedure

(Cleaning your Expobar Espresso Machine)


  1. Have the Espresso Machine ON (Heating as per normal use)
  2. Remove the single or double basket from the group handle, and replace it with the blind filter basket
  3. Into the blind filter basket, place approximately 1 - 1 1/2 teaspoons of Backflush Cleaning Powder 
  4. Lock the Group hanlde into the group head (simillar if brewing a coffee)
  5. Switch OFF the machine using the machine's power switch (not at the wall socket)
  6. While HOLDING DOWN the middle button on the keypad, switch the power back ON and the machine will commence a 5 cycle Automatic Back Flush Procedure (Use the corresponding keypad to the group you are flushing) Once the machine has commenced the cycle, release the middle button.NOTE: No water will come through the Group Spout. The back flush is now being mixed under pressure with the hot water from the group head. 
  7. The machine will automatically STOP and START for each of the 5 cycles, and the water and powder will exhaust from the machine into the drip tray.
  8. Note: If you nmeed to interrupt the 5 cycles - Turn the machine OFF and ON again. DO NOT REMOVE the group handle while under pressure
  9. Once the machine has completed the 5 cycles, ensure the group handle is not under pressure from the machine. Remove the group handle and inspect the basket (There should be some residuals from the powder and water mix with some coffee granules)
  10. With the hanldes removed, RESTART the Group head flow (as normal) so that clean water flows through the head - use the flow of the water to rinse the group handle . You may want to repeat steps 4 - 7 with no powder in the basket filter to flush any residuals of cleaing solutuion. ALWAYS REMEMBER TO EXERCISE CAUTION IN THESE STEPS AS THE MACHINE / GROUP CAN BE UNDER PRESSURE AND IS USING HEATED WATER.
  11. Once the machine has been cleaned of all backflush, with a damp cloth - wipe the group head and shower screen. Repalce the blind filter with the single/double basket - and make a coffee as per normal.
