Even though i stepped up from a Gaggia Classic, i really wanted to try installing a PID as I've studied electronics.

So i bought a used Gaggia Classic from ebay and after some research i present to you the results.

I used a Sestos PID and a made a custom box myself as i couldnt find something to fit nicely.

 

On the first video you can see the machine all around and an shot.

 

On this video you can see the steaming capabilities when using the PID (alarm function) for controlling steam temperature.

 

Hoping to sell it after i finish playing with it :)

I've got a gaggia classic and have done the mods that I feel are within my...ehem...technical ability (OPV and steam wand). Naturally I'd love a PID, so out if interest, how 'technical' was this to fit? Could a complete electrical idiot like me manage this mod with the right guidance?

Impressive - I'm not a Classic man, have only played around with my son in law's machine a bit.

 

Am interested to know the effect on the boiler drawing off that amount of steam. As I understand it, is it not possible to run the boiler dry as no water is going in during steaming.?

You are correct in steaming mode the pump does not replenish the boiler, which is why after steaming you should always refill the boiler by drawing water through brew head until water flows freely. Drawing too much steam could result in melting the thermal fuse link OR burning out the boiler elements.:o:exit:

It's very easy, really.

Yep this is correct and that is the only limitation you have. Although you have to steam for a long time to dry the boiler like that. I always refilled the boiler while doing my tests.

Best to make that clear as it appeared you just kept on steaming, other members might see it and not realise they can damage their boiler.:good:

It certainly improves the steaming performance considerably

Excellent extractions on your classic and very well produced video (liked the classical music too)

Well done:good:

The classic is as well engineered and fool-proof as a machine comes.

 

 

Minus the use of aluminium and not brass.....
