Posted Sun Oct 27, 2013, 10:45am Subject: Re: specific hazards of breville dual boiler
I have repaired Brevilles for 4 years; not a high opinion of them, BUT for the price...idk. I dislike pressurized brewing filters and really dislike using aluminum t-blocks to brew with real filter baskets. None of which really applies to the dbl boiler.
I've repaired 3 . 1st thought-I doubt the regular assembly center is making them
2nd thought- just like the 800EXXL and BES8XX machines; solenoid issues. The 8XX models have riton (sp?) plastic connectors on the solenoids, and water freely flows to and from them from the t-block, making it effectively part of the boiler system (AND the line are not insulated!!). So the fail, snap, and there is my most common 8XX Breville repairs. Not having learned about heat, the dbl boiler has a brew solenoid at the group, which has (wait for it...) EPDM o rings, that come with the solenoid. All three I have serviced had these melt away and jam up the solenoid on two occasions, and the other some how some EPDM debris made it up and out the line to the brew pressure gauge, giving the customer no end of anxiety.
They can rock fairly well, but I don't feel the materials make it a good 10+ year machine.
