    my take is probably a better fail safe feature; such as low water sensor and automatic shut off when water level/Auto refill.... that would make the Silvia a better machine than it is now...

    That's not a unit I'd want to use. .
    as i said ..Each to their own preference. !
    ..But presumably you are happy to rely on the $0.50 (+-10C) thermostat that is fitted as standard ?

    Think we're talking at crossed purposes so I'm going to but out...

    I dunno, operators breaking shit is great job security for techs...

    It surprises me that anyone with a background in process control would advocate reliance on operator intervention over improved design.
    Operator failure 1/100 procedure steps is the assumption on my current project. How often would one use an espresso machine in it's lifetime?

    A low water cutout would be less like improving performance, and more like having different sized fuel bowser nozzles for diesel and petrol. And yet, someone filling a car has presumably obtained a licence to drive one

    Mine too; controls and automation tech checking in.

    I agree up to a point; our German(?)-designed/built gear is great. Our Chinese, not so much (though the programming software is sweet).

    In an industrial process-control situation I can understand, but I suspect the Sestos PID ($40 retail including TC and SSR) will go the distance in it's current role on my Gaggia. And Auber Instruments make their PIDs in China as well. If the Sestos fails, replacing it is still half the price of a new thermostat...

    In the case of reliable PID Controllers of pretty well any kind, it is...

    Process Control and SCADA design, feature quite heavily in my background; which included a lot of testing and experimentation to eliminate unreliable componentry. Cheap never worked out to be reliable...

    Cost is not always an indicator of serviceability, as I'm sure you're aware.

    If someone wants to buy a mid-market quartz watch, I'm not gonna stop them, but the fact that it cost ten times what a Timex does doesn't make the Timex dodgy...

    *EDIT* Besides, Auber sells theirs for 37...

    Given that thorough operating procedures (simple as they may be) are provided in a User Manual, one must surmise that manufacturers such as Rancilio, expect that purchasers possess the wherewithal to actually read what the Manual says. Millions of Silvias and similar machines have been sold over the past couple of decades and many of those millions have been more than satisfied with the performance. No problem with the engineering and design as far as I can see.

    Sure, once you've got your technique sorted out, thought can be given to enhancing a machine's operational performance - not that dissimilar to owners improving the performance and handling of their motor vehicles. Doesn't mean the original vehicle was poorly engineered or designed, but possibly designed to provide a level of performance at a price. That's what Silvias and others do, IMHO...

    A well engineered design, should consider potential (or even likely) misuse by the operator and the inevitable consequences. Especially when the operator is potentially entirely reliant on your manual for operating instructions. A long history of sales with a similar design should provide plenty of useful information for targeted design improvement. Putting a footnote in the manual and excluding modes of failure from the warranty is not good design and can only be justified economically. I imagine it's one of the reasons we have statutory warranty.

    That said, you have to draw the line somewhere.

    As for temperature stability - you don't see many unicycles in the Tour de France ...

    ..It seems ridiculous to learn to compensate for a 30 C temp variation , when for $25 ( probably $5 at manufacturer cost), you can eliminate the issue completely.
    .. plus the added functionality of temperature adjustment and display. !

    I owned a sibling to the current line of Lelit machines several years ago. It was a very similar design to a Rancilio Silvia, particularly under the bonnet. The need to temperature surf never really reared its ugly head; I just allowed the machine to warm-up properly, probably 45 minutes or so, and then proceeded to pull my shots. The little beastie made excellent espresso.

    As an exercise and about eighteen months after purchasing it, I thought the addition of a small PID Controller might enhance the performance of the machine, and it did. It would warm-up more quickly, and hold the brew water temp. at a steady state much more quickly between shots. Of course, it also became possible to 'dial-in' the brew water temp. to suit different coffees and blends, which made the whole espresso experience even more interesting.

    However, the machine didn't need the PID Controller to perform, the addition of same merely enhanced an already excellently performing design.

    Thanks Barry, appreciate the pickup, have rectified it.
