    Pretty sure that such a thing does NOT exist. The Flexa has a completely different grouphead to anything else in the LSM range. All the other machines use deep 53mm baskets and the Flexa has its own very unique 57mm design and is not compatible with any basket out there as the basket is integrated into the portafilter.


    In any event.. .enjoy your new toy!

    Ok, that make sense and was new to me and the main reason for a bottomless filter (except for taste) is the beautiful crema flow as I have seen on Youtube lately. To be able to get excellent espressos was the main reason for getting this hefty piece of equipment and I am sure it will deliver. The valves/filters are removed now and today I will measure the pump pressure just to be sure that everything is in good order. Do you have any pictures of the Palm unit? That would be nice to see, or if you just can explain what it is (is it just an electronic board mounted in or a plug in unit?)

    Austrailian swedish canadian, sounds like an adventure :-) So far we have not had any snow at all in Stockholm, today we have some +8 degrees and we will have the warmest Christmas since 200 years. A couple of days ago it was warmer than last Midsomer. I guess it has to do with global heating...

    God Jul & Gott Nytt År, tack för hjälpen! :-)

      Hi again, it seems as my machine is broken... :-( I get no crema at all now and it just flows out on the spill water exit. I have tried coarser grind as well as less coffee, down to 6 grams, does not help. Could it be the spill water valve that have had a hard time with me trying?

        Perhaps the OPV (spill water valve) has a build up of minerals inside and just needs to be cleaned

          Will try that later when the house is not so busy...
          I found on the Internet that a new pump cost only some 20 Euro,Iiguess a new valve in worst case is not either expensive. Can't wait until I can get good coffee... ����

            Ok, Christmas has passed and the hectic must-dos as well. I have worked intense with the Flexa E today. Started to open up the group just to find some loose strange greenish crystals (well, not actually crystals, more like hard pieces but very green.). Cleaned everything, removed all visible chalk and put the group back in place under the boiler. Moved on to the two solenoids, one that goes to the spill water tank (OPV?) and another that goes from the boiler back to the water tank. They where full of green hard particles so this was clearly the reason for why I did not get any coffee flow out from the portafilter. A thorough clean and removal of chalk residues. From there over to the brewer pump, Ulka EX4, that did not have any green parts inside, but quite a lot of chalk. I guess the Flexa E has been standing for a couple of years without being used at all. Its as new and most likely has been used only at a couple of occasions, everything inside, spill water tray etc has no signs of water and there are only minor scratches on the stainless steel tray under the group head.

            Finally everything works as it should! Tomorrow I will grind beans to find the right settings and I need to find a good tamper that is 56mm on Internet...not that easy since it seems as most tampers around that size are 55, 57 and 58mm.

            I will also search for smaller bean hoppers for one of the grinders since the commercial grinders are huge! :-)

            Picture of the green mysterious pieces... I added Vinegar and let it rest for 4 hours and most of it was actually gone!

            I also add some pictures from the inside of the Flexa E in case someone is interested. /P
