Subject: Expobar Brewtus 1 PID Failure?
 

Hi all,

My Brewtus is maybe ten years old. Never had a failure or even a hiccup.

Buuuuuut.........

A couple days ago the temperature indication on the PID went  out. It stayed on while the machine was heating, but as soon as it got to temperature the red numbers went blank. If I turn it off and let it cool and then turn it on again, the numbers re-appears...until it reaches the set temperature of 96, at which point the numbers go out.

SO I thought I could live with that, but it got worse. Now it doesn't even get up to temp. The coffee comes out luke warm, and the digits go dark at some indeterminate mid temperature.

I have the PID removed and in my hand. I am on the cusp of ordering a replacement, but I thought I'd check to see if anyone thinks it might be the temp sensor or something else.

I am a competent home technician, and this seems to me to be an obvious PID fault (the disappearing numbers tell me it isn't the temp sensor), but I could be in error.

Anyone have a thought?

Thanks.

I'm surprised it lasted as long as it did, normally those AKO temperature controllers failed within 6 months.....perhaps being on US voltage has helped you there. If you can, retrofit a modern Gicar PID controller with SSR for the heating element. You will need a new thermal probe, because the one you have is unlikely to be suitable...but you should still be able to use the existing thermowell if you have to.

What's a good source for a kit and some actual instructions?
