Wow, old threads are great. Having stripped and descaled my Gaggia I was having a similar issue.

 

Very nearly bought a new Rancilio.

 

Gaggia is working again, well it will be once I've stripped down the solenoid again.

Just a 'Thank-you' for the advice in this thread. Had exactly the same issue after a stripdown and thorough descale, and wouldn't have 'twigged' the cause without this. (knew it was the element shorted with a few kohms to earth, but didn't realise they were unsealed). All good now.

Im perplexed reading this thread - are you guys lifting the earth from your machines on a permanent basis? That's a move that potentially results in a Darwin Award...

 

As for the earlier comment about copper pipes being used for earthing - they shouldn't ever be used for an earth. However, they have to be earth *bonded* as a safety precaution in order that if a piece of faulty electrical equipment in contact with the pipework became live, the RCD would protect you rather than a massive piece of copper in your house / building becoming live!

Not permanently. It's just temorary while the insulation on the elements dry out if you've managed to get them wet during descaling.

So long as you don't touch the machine while the earth is disconnected,it won't injure you.

It's safer to just stick the boiler in a low oven for 15-30 min or even the whole machine in a airing cupboard for a few days but that's more labor intensive and/or more time consuming.


Laissez les bons temps rouler
