    How long does it take you to backflush?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Backflushing my silvia is on the same list of "favourite" things to do along with visiting the dentist, mowing the lawn and steam cleaning the carpets.

    The reason is because from start to finish it takes me about an hour and a half and way too many litres of water (during a time of severe water restrictions) and paper towels.

    How long does it take you guys to do the backflush thing from go to whoa?

    I fill water tank and heat up machine, then put disc in pf without basket with teaspoon of Caffetto, then with plastic container to catch water run brew switch until it hisses then let water and dross drain into container, I repeat this about 6 to 8 times until it is clear water coming out, I then clean bottom of group and seal with brush and run more water through, flush out steam valve and run water through group and steam wand. Refill the tank and I"m ready to go once more, plus I clean bench area and machine casing etc. Probably takes about 30 mins after machine has heated up. I do it every Saturday as a ritual so that I dont forget!!

    Re: How long does it take you to backflush?

    Hi there
    Doesnt take me that long to backflush, I have a Giotto and use about 1/3 of the spoon of the caffetto at most and just keep flushing through into the blind filter until the water comes out clean.
    Generally takes me about 15 flushes so therefore 15 shots later but with no grinding.

    I then brush and clean the shower screen and soack the group handle and porta filter in solution for 10 mins. Do a sink shot and all is well.

    When i first got the machine i did it every week and was a little over zealous with the caffetto and as a result destroyed the food grade grease in the mechanism. Chris from Talk Coffee re packed it and its working fine, i only now clean once every two weeks.

    Re: How long does it take you to backflush?

    After heaps of experimentation, I have settled on doing a chemical backflush once a week. I tend to use a tiny amount ... like 1/3rd of a pallo tool scoop, but I use Andrews trick - flush it through once, so that detergent comes through the three-way valve, then let the PF sit in the group for five minutes. With the pump OFF!!! Then its just a matter of doing some cold water backflushes. It might take ten minutes all up, but I do it whilst cleaning up my bench, etc. This routine seems to have gone fairly easy on the grease in the group, but Im happy to grease it up every now and then if thats what it takes.

    I do have to admit that I have become a bit of a pedant; Im backflushing before every shot at home now. You wouldnt believe how much gunk you get rid of and how much cleaner the coffee tastes. It strikes me that part of the problem is definitely that filter baskets arent made to fit shower screens. Im probably widening the gap and worsening the problem by using the Ascaso filter basket that Synesso uses. I might switch back to a LM basket and see if that changes things. Forget tampers fitted to baskets; I want baskets fitted to showerscreens!

    Yeah. Sometimes it does get a bit ridiculous for a 30mL drink!

    Cheers,

    Luca

    90 minutes to backflush!? Are you sure you didnt mean descale? If it takes that long to backflush you are doing something wrong. Ten or fifteen minutes at the most should be sufficient.

    Please read my How-To on backflushing in the right-hand column of my website.

    Fair dinkum it takes me that long. I use the Cafetto Evo and I must admit Im a bit concerned about leaving any trace of it in the machine so I do a lot of flushes to make sure I get rid of it. If it was biodegradable, I wouldnt be that concerned (is it?).

    What I do is after pre-heating, I replace the normal filter with the blind filter, lock it in, run the brew switch until the sound changes indicating pressure overflow and off the brew switch. After this I do it for another 10-15 times before removing the PF. At the same time I have a kettle full boiling water... After that I switch off the silvia to cool it down (while letting some cafetto sit inside the machine). The cool down period is 15-20 minutes. Atthis time I put the boiling water into a salad bowl type container and add Cafetto in it and put in the PF, filter baskets as well as the shower screen, shower screen screw and the other bits that sits with the shower screen. I then take a toothbrush and dip it in the caffetto water and brush the grouphead without the shower screen on as well as the PF lock-in part . Because I used cafetto for that, it then takes me a while longer to "rinse" it out using paper towels, sponges at which point my benchtop is pretty much a wet mess. Ideally that should take me 15-20 minutes during the colldown but I think it takes a bit longer than that. Then I rinse off the PF, filter baskets, shower screen etc using another kettle full of boiling water and then rinse again with lukewarm water until there is no hint of soapy feeling on my fingers. Ill then put back the shower screen and switch on the silvia and run the pump into the blind filter and most times, much cleaner water would have come out by then. I do this for another 15 times, take out the PF to rinse it, lock it back and do it again for another 15 times. All in all, Ill use up 2 full tanks (silvia reservoir) of water for that, as well as the water rinsing out the PF separately etc... (which is why I said I use way too much water). Am I overdoing it?

    I will take a look at your site to see what you do...

    Re: How long does it take you to backflush?

    Say, which part of my process am I taking too long in? Am I being overzealous with the rinsing off of the cafetto?

    Why are you rinsing with sponges and paper towels? I just use the "portafilter wriggle" technique to rinse it off the grouphead, then backflush with clean water several times, pull a "seasoning" shot, and thats about it.

    Re: How long does it take you to backflush?

    I do like to leave the Cafetto in the machine for 10-15mins before rinsing and backflushing though, as that seems to remove a lot more coffee residue. I also soak the portafilter, filter basket, and often the showerscreen as well, in Cafetto for an hour or so to get it really clean. So it probably takes me a while, but itís not very time consuming as most of that time is soaking time.

    good advice Bill - this necessity is often overlooked. However, I dont really think you need to unscrew the showerscreen & soak it, as a fairly detailed backflushing process should do the job in the first place. ;)

    Re: How long does it take you to backflush?

    10 minutes would pull me up..... Let the PF and Baskets soak in Caffeto overnight. Use this routine once per week. Daily I just do a couple of water only backflush cycles and then a good flush through the PF/Basket before switching off at night.

    As an addendum I flush the basket/PF with the first cooling flush before every shot and then flush it out again after the shot. After each shot I do a series of cleaning/flushing shots during which the grouphead/shower screen is cleaned with a brush. Finishing up with a plain water backflush. This is done on every shot with a full chemical backflush and basket/PF cleaning done once a week.
