  • Silvia Auber PID cutting out

    Hi guys,

    I hope you can help me out of a dilemma that is annoying me?

    I have a Silvia with Auber PID that has been running flawlessly for a couple of years. Now it has developed a habit of randomly powering off the PID and in doing so no longer heats the boiler.

    Most times it works fine if I am making two coffees, but more than that it is a lottery.

    I have opened it up and checked/ re terminated all connections and all appears OK.

    I am at the stage where I will order the controller from Jetblack Espresso (where I purchased the kit). Before I do that though I thought I would throw it out to anyone that has seen this symptom before. Maybe my connections are still dodgy, but I don't think so.

    My wife really appreciates any help/ advice.

    Cheers,

    Rick

    G'day Rick...

    Could be a bad solder joint on the PCB, a dodgy Electrolytic Capacitor, etc etc....
    If you have an electronics tech. mate who could have a look at it for you, that may lead to a happy ending but not worth the time to fix in a commercial situation...

    It's definitely the PID Controller, eh and not the SSR?

      Suspect a faulty switchmode power supply, heat related failure. Probably easiest to replace, unless it's blindingly obvious when you open it up

        Thanks Mal,

        I tend to think it could be within the PID controller, SSR is working fine and I think unlikely to be the cause.

        I will get a new controller and see how it goes.

        90% of the time it is only the two of us having a coffee so not really a major problem, just annoying.

        Thanks again

          I tend to agree, not easy to open up anyway.

          I think replacement is the answer,

          Thanks for the reply
