1. Let the machine heat up for 5 minutes;
2. remove the cartridge from the filter, if fitted;
3. put 300 cc white vinegar + 100 cc water in the container. Be prepared to tilt the container to prevent the machine from
switching off on account of low water levels and take care never to let the pump operate without any water. There fore,
add more water and vinegar solution if necessary. Another alternative is to leave the container full of water and place the
pipes in a separate measuring jug containing the vinegar and water solution made up in the proportions described above.
This latter option has the advantage that you can see when enough water has flowed through the machine;
4. let the water run through the unit until you can smell the vinegar solution in the water;
5. let the water run through the steam nozzle until it begins to smell of vinegar;
6. 4 and 5 above, when performed in this order ensure that the pipes of the unit and on the steam nozzle are filled with
water containing the vinegar solution.
7. Insert the blind filter in the filter holder and insert the filter holder into the unit;
8. Lift the lever for 6 - 8 seconds until the pressure reads 9 or 10 bar; then switch off the machine. This will switch off the pump,
given that you do NOT want the unit to lose pressure (make sure that the unit E61 is full of water/vinegar solution);
9. leave the machine switched off overnight (approximately 12 hours) then empty out the water container;
10. wash the container and fill it with clean water;
11. depressurise the unit (by lowering the lever);
12. switch on the machine and wait a few minutes for it to heat up (carefully monitor the pressure if a pressure gauge is fitted
to the machine, and dispense water through the steam nozzle if the pressure should exceed 9 bar while the machine
is heating). Insert the blind filter and insert the filter holder beneath the unit, back flush the machine 6 or 7 times (see
paragraph 6.2);
13. remove the filter holder;
14. dispense water through the unit for periods of 20 seconds, waiting for 15 seconds between each one.
Do this 5 times;
15. dispense water from the steam nozzle until you can no longer smell any vinegar;
16. dispense water through the unit until you can no longer smell any vinegar;
17. replace the blind filter and back flush 5 times (see back flushing operation);
18. switch off the machine;
19. fill the container with clean water and start the machine again as described in the instruction manual;
20. dispense 30 - 40 cc of water through the unit into a container and make sure that it does not smell of vinegar or taste
unpleasant. Dispense the same amount of water through the steam nozzle into a container and make sure that it does
not smell of vinegar or taste unpleasant. If any unpleasant smell or taste remains, distribute more water through the unit
and steam nozzle and check it again;
21. the machine is now ready to be used again.
