    I'm giving auto tune a spin, definately getting better results with it.

    The only issue i'm having now is the Steam Thermostat doesn't cut out until 157*C which is aufully close to the main cut off switch @ 165*C.
    There is a bit of play on the thermostat since installing the thermocoupler so i'm wondering if that is causing the issue or if I need to replace
    the Thermostat.

    Cheers Rob.

      My steamers all get up around that temp, its alarming isn't it. Even more so when you consider that's the temp they have been getting up to all along! Interesting what you discover with accurate temperature monitoring. I have left the steamers all on the original thermostat, alternatively you could use the alarm output to control the steam temp if you so desired.

      BTW did you have to cut away a little bit of the thicker black painted steel plate on the left lower side beneath the stainless control panel cover to make room for your cabling loom to the controller box?

        In reality it's not actually an issue for me because I usually start clearing out the wet steam at 120*C and steam milk from there so it rarely gets above 140*C.
        Not sure what everyone else does?

        Just the odd occasion when you get distracted and it would skyrocket.

          ok, checked the OPV and it was peaking above 11.5 bar, now with another pair of copper washers its pretty much bang on 9 bar now.

            You got lucky!

            Mine was 11.5 Bar as well, adding a second washer droppied down a bit but not 9 bar. I'll try again with 2 x new washers perhaps the old one have been squashed down too much.





            Did you use a closed system to test? here's mine



            Cheers Rob.

              yes closed system test as well, same setup as yours except i had a little bit of tube between elbow and gauge fitting. bit of a pain using the Lucy portafilter with the notch, had to cut a bit of insertion rubber to plug the notch, next time i will use my newer silvia portafilter without the notch.

              Originally i tried 2 copper washers and a fibre washer between then and it was way to low under 7 bar, removing the fibre washer made it about 8.5 bar.

              the copper washers i used were a little convex so i flattened them down and dressed them with emery and then i hit 9 bar so it was a bit of trial and error, i did have a bit of scale in the OPV which possibly could have effected the seating of the valve as well.

              but all good now, will be interesting to see what my silvia V1 down at the beach house is set to.

                I got the notch on the portafilter brazed & cleaned up by a very nice forum member

                Just tested mine again with 2 washers and it reads 155 PSI which is 10.68 bar, I'm going to try some thread tape around the washers to see if that will give it a bit less pressure.

                  i suspect my washers were a tad thicker than yours,
                  quick tip, go off the kPa scale, 100kPa is very close to 1 bar with 10 meters of H2O head pretty much one atmosphere :-)

                    Ah good to know!

                    I got there in the end added a decent amount of thread tape and kept tightening it up unti it hit 9 Bar.

                      Don't forget with no flow you should set to ~9.5-10 as the pressure will drop with flow.

                      Not super critical as you are in the ballpark.

                      Cheers

                          Hey Guys,

                          Well after 5 Months of everyday usage, My PID bellowed out with black smoke and shorted out my RCD.
                          I'm just going to order another one but does anyone have any idea how I can prevent this from happeing?
                          Some sort of inline fuse?

                          Cheers Rob.

                            G'day Rob...

                            Failure could have been initiated by some unfriendly voltage spikes via the mains supply.
                            Wouldn't hurt to grab a Belkin Surge Protection device or similar and yes, an In-line fuse
                            to protect the rest of your machine from any mishaps with the PID unit wouldn't be a bad
                            idea also...

                            Mal.

                              I would say a surge device or fuse would likely not have saved this controller. I have 3 and none have bitten the dust yet but might just be worthwhile to grab a spare .

                                i shoulda grabbed a spare controller... one of my xmt7100s (the one on my silvia installed sep 2014) died this morning after letting out a little puff of smoke, looks like i will be temperature surfing until a replacement arrives.

                                So this Auber clone controller lasted just over 2 years before giving up the ghost, not too bad for a $27 controller i guess.
