    My M4D clumped a bit until it was broken in. The clumps were soft and easily 'mashed' by the tamper.

    Hi Greg,

    How long did you need before the grinder has been broken in?

    It took me about 1 to 1.5kgs of beans.

    Thanks barri.

    I've definitely gone through more beans than that and I'm still getting clumping every time. It's not a huge problem but I just expected better for a grinder of this price range!

    I'd say that's right - I've had virtually no clumping up here from the M4 or the conical, but we're away from the coast and at high altitude, so the humidity is pretty low all year round. I wouldn't blame the grinder on this point, although the speed of a big conical will 'aerate' the grinds more I guess as they chuck them out!

    Don't think the clumping affects the flavour anyway

    Keep in mind that after you tamp there are no clumps. Its a non issue other than it doesn't look that nice.

    Hi all,

    Have had my Macap M4D for about 2 years and have put maybe 50Kg through it. I'm the second owner and whilst its hard to know how much coffee went through it before I had it (another home user), I'm starting to wonder if the blades are starting to get a little worn. I find it very hard to isolate this as being the cause as there are so many variables (dose, technique, grind etc etc) but I get so much variance from shot to shot that it has got me wondering. I have another hand grinder (Portaspresso Rosco hand grinder) which I love - it always delivers an interesting pour with much more mouthfeel than my macap mostly does.

    Would my best bet be to take apart the blades and feel if they are still sharp? I'm wondering if wiser heads can point my in the right direction in which to begin...

    Hi Pretzal
    It is worth a good clean first if you haven't ever done that before - I always found I could taste the difference when I scraped away all the ground in gunk from between the burrs! I used to do mine every 6 months or so…

    But, I ended up replacing the burrs after about 5 years. I could feel that the burr edge was no longer sharp to touch (but I'm also a fussy ex - industrial arts teacher so can obsess about sharp tools!) and also notice that the grind was less consistent and the grinder also less responsive to changes. When new, I could adjust the micro-adjuster around 1/4 to half turn to go from tight pour to gush. When older, it was just 'sloppy' to get in the zone…

    Cheers Matt

    Thanks very much for your response Matt. I ran some of the caffetto grinder cleaner a month or so ago but whilst I've owned it I haven't taken the burrs apart yet to give it a good clean mostly as it doesn't look convenient to do. I've got the day off tomorrow so I'll take it apart, clean it up and check out the burrs while I'm at it.

    Well I took apart the burrs and gave it a good clean. I didn't think it was that dirty really compared to an old cafe grinder I cleaned out a few years ago but that's a whole 'nother story ��. Most of the coffee brushed out fairly easily from the burrs and surrounds and a thorough vacuuming followed. There were a couple of nicks in the burrs, which was surprising to me, but they felt relatively sharp in that there was a bit of resistance on my finger tips when lightly dragged across them.

    I've only made about 4 coffees since cleaning it, whilst it's hard to say with authority after such a small sample, it seems to have had an impressive impact. I left the double shot time the same and just adjusted the grind until I got an acceptable pour. The dose seems to be a bit lower but it tastes much much better (not perfect). Unfortunately I'm over the other side of the country for 5 days so won't be able to sample more until I return home, but I'm glad I've cleaned it as the results have been intriguing and encouraging��

    That was always my finding too - surprising the difference it made when it didn't seem that bad! But then again we shouldn't be surprised- try cutting with a dirty chefs knife sometime

    I have a M4D about 7 yrs old. The ON/OFF switch on the side has stopped working. Would appreciate some advice. Is the switch easy to replace? Can it be removed/replaced from outside the machine without taking the whole machine apart by unscrewing from the bottom?
    I live in a regional area so easy access to a repairer is not possible.
    Any DIY diagram would be appreciated.
    Thanks

    Having just pimped my grinder here: Pimping my Macap M4D Grinder I can tell you that the disassembly is very straight forward. You could have very good access to the switch in under a minute by taking 3 screws from the bottom of the grinder to get access from below. It might be possible to remove without unscrewing the bottom but you would risk damaging the paintwork/chrome if you did. It is designed so that it doesn't fall out as it has pinch style tabs on the inside to keep it in place.

    It seems like a fairly standard switch. I would firstly try the company you bought it from to see if they carry spares. Failing that I would try the quote form at the bottom of the page to email all the sponsors to see if they can supply the part you're after. If that doesn't work PM me I have a exploded parts diagram and another company's details. If that doesn't work then there are places that do sell switches like that - I know because I had to replace a switch on a cement mixer that wasnt that different! I don't know where you're located but I can recommend one in Adelaide if you need.

    Hope that helps.

    Thanks for your reply. I shall attempt to extract the switch by unscrewing the base as you suggest, then see how I go.

    I've done a search of this thread, but nothing relevant came up.

    Our M4D has developed a problem where it will sometimes start and sometimes not.
    It is about 6-7 years old.
    It is set on "continuous". However when pushing the portafilter against the button, the motor sometimes starts but sometimes won't.
    You hear the click of the button but the motor won't start.
    If you persist, the motor will eventually start.
    It sounds like the brushes may be worn, but I really am clutching at straws.

    Anyone had this experience or knows how to fix it?

    G'day mate...

    No brushes with this type of motor.
    Most likely problem is that the Start/Run Capacitor is cactus. If you don't know what that is, then it's a trip off to a qualified and licensed Tech.
    Also, if the grinder internals haven't been cleaned for some time, it may possible be that excess coffee residue could be binding up the rotating burr. Hopefully, that is not the issue...

    Thanks Mal.
    I'm fairly experienced with a soldering iron.
    Is the cap easy to obtain?
    i.e. Tandy, Jaycar, etc?

    Mine had the same symptoms and as the guys suggested it was the SC. I didn't replace mine but had one of our sponsors take care of it for me, all good since
