    Is this normal?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi all,

    Fired up the Carimali tentatively today for the first time..

    Pump came on, ran for a few minutes then cut out, all good so far.

    Turned on the boiler power (separate switch on the Carimali) and things started heating, also good.

    Tried one of the brew switches while this was happening and got no response from any of them. The question is, is it normal or common for the switches to be disabled until the boiler is up to pressure and the ready light comes on? It seems unlikely that everything would be non-functional otherwise, so Im hoping..

    I ask because I cant wait until that point and test, because I seem to have a pressure leak from the relief valve, it starts bubbling a little liquid and then a small jet of steam quite soon in to the heating cycle. So waiting for it to cool down now to remove the valve and clean it.

    Thanks for any info.

    Cheers,

    Dennis

    Hello Dennis.


    "Pump came on, ran for a few minutes then cut out, all good so far..."

    This may not be such a good thing at all... if the boiler had been drained and the water level was very low, then yes...all good... otherwise....?

    "Tried one of the brew switches while this was happening and got no response from any of them. The *question is, is it normal or common for the switches to be disabled until the boiler is up to pressure and the ready light comes on?

    Carimali is not really a common brand machine over here and your best bet would be to ask whoever is a service agent for the dreaded "Robert Timms" as they have been / or were / or whatever / the importer here for some time. It seems very *unlikely* there would be some kind of control to disable flow from the groups until the boiler has reached operating pressure...certainly this does not happen on any reqular commercial machines I can remember ever working on.

    But you havent told us if the groups were subsequently switched as normal once the boiler DID reach operating pressure....in which case.......I guess it must be a feature of this model and quite OK!

    "I ask because I cant wait until that point and test, because I seem to have a pressure leak from the relief valve, it starts bubbling a little liquid and then a small jet of steam quite soon in to the heating cycle. So waiting for it to cool down now to remove the valve and clean it. "

    Aha...Not so Im afraid. There is no reason why you cant operate the machine while the pressure relief valve is leaking. Just make sure any condensed water doesnt end up on something electrical....and it usually wont, because leaking steam or water will steam straight off the surface of the surrounding hot boiler. / OR,
    Are you sure you are not confusing the pressure relief valve with the anti vaccum valve because it is quite common for anti vaccum valves to leak */ spit steam at first, then seal up as more pressure builds in the boiler. Anti vacuum valves that DONT seal once a good head of steam has been reached can be "corrected" by simply tapping the leaking nipple with a screw driver until it seats itself in a position that does not leak. *

    If it does turn out to be a leaking safety valve (pressure relief valve) and you dismantle it....make sure to count the number of turns it takes to get the bits apart and when you have repaired it ( if that is possible), screw the bits back up together to the same number of turms as you undid it originally...or you will end up on a different setting for *pressure* relief.

    "Thanks for any info".

    Youre welcome.

    Regardz,
    FC.

    Re: Is this normal?

    Many thanks FC, things have progressed since I originally posted.
    Firstly I had indeed deduced that it was the vacuum valve leaking, not the relief valve, and a quick dismantle, clean and reinstall fixed that, and everything came up to pressure fine.

    That allowed me to ascertain that in fact there is *not* a cutout for the group switching, all dead still :(. Things got better though, some fiddling and tightening of wiring connections and one group is back in action. The other one Im hoping is not far off now that Ive narrowed it to one control box to concentrate on.

    Other than that, so far I have: one leaking steam wand - slight relocation of the valve in the frame should fix that as it seems to simply be mechanical interference between the handle and front panel preventing the valve closing entirely; apparently non-operational flow sensing on the operating group (at least), most likely more electrical connection problems I expect.

    At least so far I have a one-group manual machine hopefully capable of very good coffee :)

    Cheers,

    Dennis

    PS. Hoping to remove the after-image of the dreaded Robert Timms logo from the back panel of the machine...

    Im relieved to hear that the machine is almost up and running...

    The guy supposedly had just had the machine serviced, too!

    Cheers....

    Thanks Stratford, from what he told me I gather it was serviced just before he bought it but was leaking water. He dismantled it and fixed that leak but did little else other the disassembly required to do that. This disturbing of long-untouched electrical connectors is probably where the problems have crept in, as well as potentially inoorrect reconnections. He seems genuine and helpful and really i fully expected some stuff to not be working out of the box so to speak :) Of course if it turns out to be more wrong with it than claimed my opinion may change!

    Cheers,

    Dennis

    Re: Is this normal?

    A traders point of view:

    The "just been serviced" statement is a beauty and good food for thought in this forum.

    If no invoice can be provided, then everyone should assume the statement is ill founded and you should consider it as totally irrelevant...ie the equipment purchased is "as is where is" and thats it.

    The "just been serviced" statement also goes both ways....that is it causes upset in more ways than you might think as a consumer.....we as traders occasionally get a call or a visit from someone that bought equipment from elsewhere and they make the statement that they were advised we apparently "serviced it" *just before it was sold....

    Its an interesting statement.

    Firsty there is no such thing as a "service". You fix a manifested problem...and thats it...otherwise, you would have to pull half the machine apart and replace or recondition anything that might fail sometime in the future. And this of course still would not guarantee against something failing tomorrow!

    So in the case of people coming in saying something was *"just serviced" before they bought it *the truth is usually that as service providers we either:
    actually did fix a specific problem just before it was sold OR
    actually fixed something (anything) many months ago OR
    we never heard or the vendor or the equipment AND
    whatever was fixed is probably not the prpblem that is manifesting itself at this particular time...and
    there wouldnt be any form of guarantee anyway given most of the preceeding points......

    So basically as stated above when CS participants are faced with the statement that something "has just been serviced" you should ask what specifically was fixed and/ or ask *how long ago and ask to see the invoice. This is not so that you can hold some poor "serviceman" to some kind of theoretical guarantee on some "fix" but rather, just to note that a problem was repaired some time in the past (check the date on the invoice, thats the only reason for wanting to see it) and hopefully there arent any others.

    Remember, unless equipment is actually sold to you by a trader who offered some form of "guarantee", the "just been serviced" statement is just a furphy, the item is as is where is and thats it, you takes your chances that it will run ok and if not, well you will fix it even if it was only just "fixed" beforehand.

    Hope this helps forum participants being served up with this basically irrelevant statement when you are checking out used equipment.

    Regardz,
    FC.

    Good advice FC. In fact I didnt bother to ask for details of the alleged service precisely because I put no stock in the claim (which was second-hand in any case) in the first place. The decision to purchase was based entirely on other factors, thus so far Im pleasantly surprised that things are looking promising :)

    Cheers,

    Dennis
