    Re: Random pump cut outs - 2 group Milano (wega)

    I suggest you keep trying, the group tripping out will most likely be a group solenoid shorting to earth, have your electrician mate disconnect it and try again.

    Alternatively call the Tech who replaced the pump and tell him the pump wasnt the problem, You shouldnt have to pay the full rate if it was misdiagnosed by the tech in the first place.

      Yea... If they replaced the motor, then by law and GMP, let alone duty of care and standard requirements of any electrical repair... Earth leakage should have been checked..

      While it may have passed, if something is getting old etc the test value would have been down a bit and that should have raised a warning flag..

      1M to earth is the basic min, but you should be at 10M or higher.  Once you start getting lower than 5M, it is advisable to start checking to se if it is the elements or something else.  With element disconnected you should be 10 or even 20M plus.  Anything lower would then point to something else at risk.

      Standard practice for any one with a duty of care and an understanding that if they perform work and return to service; they could be held responsible for any nasty outcomes.  Yes,  things could be tested as OK and then fail the next day, but depending on the fault etc an investigator with any real understanding will start to ask hard questions as to what was done and where the relevant paper work might be.  

      For me I have to have in date calibration certificates for all test equipment and document the test results on all service documentation. If an item fails, one has to record the pre and post test results and then the test results of the failed item to ensure all the measurements  make sense.  

      Traceability and risk management. NOTE: Many dont go to this extent but in Health, and where the media love a good story and to point the finger. If you screw up in one small area and something goes wrong... You get hung out to dry and if some one gets killed it get a little messy.

      PS. Try documenting static  ;D  So many report electrical shock, then have to have an echo done and the equipment taken off line.  Many hours of checking and double checking to prove that the machine is safe and some ones frilly underwear and or plastic soles on a carpeted floor OR a very dry environment will often cause static and it can be at extreme values.

      Sorry... Hobby horse again.  A good tec never takes one measurement and never assumes

        I should probably update this thread for the sake of anyone experiencing similar problems.

        Turns out the earth leakage problem was a dead solenoid as tek correctly suggested. Around $89 from Coffeeparts and 10 minutes work. Safe for anyone with half a brain to replace.

        The random pump cutouts have been suggested to me offline as a dying  capacitor. Around $24 from coffeeparts and even easier than the solenoid to replace. The problem with this issue is it is random so theres no way to know if its resolved yet. *fingers crossed*

        Makes you wonder why a so called reputable espresso repair place couldnt figure it out so easily. From now on Im going to do my own repairs.

            knowing how to use a multimeter is always helpful

              Hey Acog just wondering if you solved this issue as Im having it with my 3 group wega airy. Have already replaced the motor solenoid but didnt fix.

              Was it the motor as I suspect?

              Cheers

                meant capacitor

                  Hi G,

                  The outcome of my problem was the motor. I had replaced the capacitor and the problem improved, but didnt go away completely. Ive since replaced the entire motor and given the machine a good thrashing under real circumstances and had no problems.
