    Take a print of the picture in post 25 to akihabra, one of the stall holders will have the switch and will know who can instal it if you are not able to do it yourself.

    Also look at screwing the switch "inwards" towards the chassis. Locknut on the inside of the fascia, just loosen and adjust so the switch is not sticking out as far. This means actuation is a little further on the roll up of the lever, but mine has been fine like this for a long time (5+years now).

    Yep...

    Handily though, sites like E14 usually provide all item dimensions to facilitate identifying the correct switch. Even better, to buy direct from one of our Site Sponsors. I'm sure there'd be no trouble in getting one sent to you. Bit like sending coal to Newcastle though...

    An addendum to the above: check size carefully if buying from RS or Element 14. The roller plunger switches they stock are the industrial standard which is too big to fit a coffee machine, especially a VBM junior: both the body of the switch (about 50mm long) and the diameter of the roller (about 12mm) will cause problems.

    All the ones in the pic above are this size, I haven't been able to find the subminiature size needed through RS, Element14, Mouser or Digikey so I bought mine from a coffee machine spare parts place.

    These are normally easy to acquire, several companies in Japan make them for the rest of us to use.
    Some samples here...

    Don't say I didn't tell you!
    Ha. Thanks for the tip, Caffeinator. Unfortunately I’m in Tokyo, and the only guy I know of in Japan who services these machines is on the other side of the country. The cost of sending the machine there and back usually amounts to more than the service charge. Despite that, I still send it over every couple of years.

    I’ll check out that roller microswitch. Cheers.

    "I solved mine by adjusting the lever further in ... ".

    Apologies for reviving a thread that's been dormant for the better part of a decade, but I've recently experienced the same issue with my lever/switch -- the popping noise is getting unbearable, so I came online to see what I could do. Is the adjustment of the switch an easy procedure? Or will I have to get inside the machine and tinker for a while? At the moment, I'm getting around the problem by using one hand to push in the switch, then the other to pull up the lever, but it's only a band-aid solution. I'd like to take care of the problem permanently, or at least until it recurs, which seems to be every 3-4 years in my case (the last two times, I was due to get the machine serviced anyway, so someone else fixed the problem for me). Thanks in advance. (Hopefully you still check this site!)

    (Lube inside the lever mechanism, and a smear on the lobe that pushes the microswitch made a huge difference to my COFFEE machine.)

    NO!!! Its not a scale inhibitor either. Pulycafe etc are backflush powders. They have nothing to do with descaling whatsoever.
    Backflush / Rinse / Chemical cleaner / Descaler scale inhibitor / group / basket / temperature etc etc

    The wrong word can complicate things... And some users wonder; why we some times get anal and try to spell out things..

    Backflushing with descaler
    I really hope that was a typo. NEVER backflush with descaler
    Yep - thanks for pointing that out! definate slip of the tongue  :-X
    i meant "scale inhibitor" ie, detergent (pulycaf etc)

    Agreed Mal, just give your vendor or importer a call as it helps us to look busy for the boss.

    We do our best to check lever feel and micro switch alignment when we do our pre-sale bench test. I would say if the unit is new and you are feeling a bump in action that the micro switch needs to be set back a mm as suggested Mr Talk.

    Otherwise its important to finish off a back wash with a good rinse back wash (no chemicals same procedure). This will make sure there is no residual chemical to harden and damage your lever group action. Then its a couple of seasoning shots to get the lever feel back to smooth.

    A dab of lubricant on the lever base (where the lever mechanism hits the micro switch) can sometimes be an easy fix .

    IMO its rare that the issue would be a faulty lever switch on a new unit.

    can strip away a lot of the grease from the levers internal cam.

    this makes the lever movement sticky.. its a problem on all e61 machines

    Not if they have a toggle switch or a touchpad!

    Then you get to replace both in time, and probably the group solenoid as well  :
    Just pointing out an over-generalisation - not making a value judgement!
