    Do you wiggle?

    A tip known to most older Snobs, I thought worth mentioning for the benefit of newcomers to the site.

    The portafilter wiggle helps in keeping the group head area clean.

    When finishing a session with the machine still turned on lock the portafilter lightly into place then activate the pump, when the water starts to flow wiggle the PF from lightly locked to unlocked for a few seconds, helps keep the group head and shower screen clean and free of coffee grounds.

    If your machine has a three way over pressure valve then carrying out the same wiggle with a blind filter will do an even better job.

    I recently bought one of this for the wiggling, seems to do the job pretty well probably better than using a PF

    Yes I do this too on my Giotto PP but I use the blind filter and don't lock it in (if you try to unlock while under pressure, you risk spraying scalding water everywhere). Just insert loosely and gently wiggle back and forth for a few seconds.
    What I also do after the last chemical backflush cycle is remove the group handle and scrub the inside of the grouphead with a brush. Then I re-insert the grouphandle (with blind filter), give it a 'wiggle' flush before continuing with the backflush rinse cycles. It's sometimes surprising how much gunk is dislodged.

    Yep - a quick pressured backflush followed by a wiggle flush after every shot keeps the machine clean and the espresso mean

    I have a second style of portafilter wiggle that I use - with any sort of grind on demand style grinder (Mazzer Electronics, the Santos 55 I use at home, or any others) I rest the portafilter on the handle rest then twist the handle rapidly back and forth to rock the portafilter against the rest as the grounds fall into it, so that the grounds settle into the basket. Especially with deeper baskets where the correct dose would form a mound above the edge of the basket before tamping, it helps reduce mess/wastage, and by reducing wastage it also makes the dose amount more consistent.

    An old Asian man showed me this when I bought my EM7000 second-hand from him. I'd never seen anyone do it before, but it pretty much gets 99.9% of the grinds out of there, with minimal mess, compared with a brush or cloth technique! I thought I'd just picked up his weird habit until I saw this thread :-)

    The wiggle is part of my backflush routine with a blind basket. Can’t remember where I picked it up, I think just the first youtube video I watched on ‘how to backflush’.

    (I'm a Coffee Trainer, just giving my 2 cents :P)

    This was actually one of the very first things I was shown when it came to cleaning a coffee machine, at the cafe I work casual at it still astounds me as to how much I can get out from the shower area with a simple wiggle. Even when I remind my other colleagues about it constantly.

    Not only do I think it's good practice but also because I personally found what happens if you don't do that or backflush it properly (as well as other cleaning procedures of course). The owner of the cafe had moved the current machine from another store that closed, and the shower filter was completely blocked.. took me a good while of fixing EVERYTHING ELSE before thinking of checking the shower filter itself, so i've always made it a habit to do it myself constantly as well as to get everyone else to make sure they do it!

    (We had quite a few complaints about the coffee as you could imagine)

    Glad it piqued your interest to have a look It's aimed to make it easier for schools to organise this sort of training for students. Since it can be quite a hassle with permissions slips, cost, time etc (trying not to make this sound like an advertisement )

    I wiggle all the time, I pull the shower screen and gasket out every now and then to check them.
    They have always come out clean as a whistle.

    This must have been in the Instructions with my machine as I have always regarded it as a necessary part of the post-pour cleaning process. I don't know how else you would clean the group which is just loaded with grind after a pour.
    I would not have thought of it as a "wiggle". I just let the water flow and lock and unlock the portafilter. On the last one I let it build up pressure as I am slowly backing off the portafilter so that the last of the grind is expelled with a little bit of pressure behind it.
    I still need to give the inside of the group and shower screen a good wipe with a cloth to remove the remaining coffee.

    Yes, I like to wiggle. Especially when backflushing with a blind basket, gets the cleaner all up in dat shower screen.
