Silvia Auber PID cutting out

[rickd Junior Member Find all posts View Profile Close rickd]

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
