    Leaking Nemox

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I just bought a Nemox dell Opera (similar to the Napoletana - see http://www.lygonimport.com.au/product_details.php?pid=49 for details) and have a quick question. A couple of times in my first week with it, I have filled the coffee filter too much, or have tamped the coffee too firmly, as its taken too long for the espresso to brew. Thats fine - teaches me to use less coffee or not tamp so firm.

    But what is more worrying is that when this happens, the machine leaks - there are drips from the right of the front of the machine, just below the switches. My question is, is this leaking just a sign that Ive overfilled the coffee basket, or is it more serious than that and I should get it looked at?

    All advice is appreciated.

    Timothy

    Id try to fill the basket correctly and tamp and get my 25 second run-of-the mill shot first. Youll probably find its just coffee escaping the group seal.

    Some of these machines seem to leak a little coffee around the portafilter until the the gasket breaks in a little.

    See how you go then -

    If it is leaking water (not coffee) from the position you describe, it can only be coming from the boiler asssembly therefore, take it back and have it checked.

    Regardez,

    Hi Timothy,

    I had a similar problem with my machine (Imat Mokita Super Inox... aka Nemox w/o Grinder) and discovered, with Alan Frews very valuable assistance, that the problem was with the "Swivel" fitting on the Silicone Tubing that goes from the Pressure Relief Valve to the Water Reservoir.

    The PRV is fitted to the discharge end of the ULKA Pump where the High Pressure line goes off to the Boiler. All that had to be done was to remove the Rubber Swivel Fitting from the PRV, it just pulls of with relatively little force, check it to make sure that there is no foreign matter in there, clean if necessary and then push it firmly back on to the nipple of the PRV so that it wont pop off.

    Mine had what appeared to be a small O-ring segment inside the fitting. I just removed this and pushed the Swivel Fitting back on to the PRV Nipple and that was the problem solved. The reason you only see water leaking from your machine when you "stall" the pump is that most of the water from the pump is being diverted back to the reservoir under these conditions and if the Swivel Fitting is not properly attached to the PRV or something is preventing a proper seal, then that diverted water will leak and exit from the machine via what ever is the easiest path.

    Hope this helps you out. All the best,

    Mal.

    Suggest you call the vendor, importer or service agent, ask advice, see if they mind you getting into the machine or whether this would void your warranty.

    Hi F_C and Timothy,

    Good advice F_C. In my case Alan Frew was the vendor from whom I purchased my equipment and it was only after talking to him about the problem that he suggested I should open up the machine and do as I indicated above.

    Yessir, always consult with the vendor before opening up any machine still covered by manufacturers warranty. All the best,

    Mal.
