Breville BES900 Dual Boiler - Owners thread

[snoopen]

Good on you. I was going to suggest that when the symptoms you report happen, it's often some kind of blockage in the group/solenoid pad complex. I have blamed these blockages before on scale OR corrosion damage from too high chlorides in your water.

Here is what my old -900 looked like from more than five years of water with no Ca and Mg (the components of scale), and no chlorides (which cause corrosion):

Looks like the machine I acquired was a little less cared for:

Thanks for sharing. I used your picture above in my "what to expect with good water" thread on HB. That was very kind of you to go to the trouble of taking off the solenoid and taking a nice snap, with the knowledge that you are not even keeping the machine. The community is a better place because of sharing like that.

That's great, Peter. I figure my pictures are a great reminder to take care of your machines.

I've updated my shared gallery with pictures of all the parts I've salvaged as well as the damage caused by not addressing the leaking water sooner.

In the gallery there's a blue bucket with all the junk I washed out of the large boiler. As well as a picture showing a metal strap on that boiler that had rusted all the way through. I do wonder how long the steam leak was happening and ignored by all it's previous owners.

I've found a home for some of the parts, but have plenty more as you'll see if anyone is interested.

Usually the steam leak presents as other symptoms such as runaway heating or tripping the protection circuit at the wall. People (wrongly), chalk that up to crap electrics. But it’s not. It’s the typical symptoms from a leaking steam mist on the triac board above the steam boiler. That strange electrical behavior goes away after you fix the leak with fresh o-rings, and dry out the triac board.

Hi, all. I recently replaced my o-rings and leaky machine (BES900xl) was fixed! However, after about a week, the machine will not heat past 153 F°. And it sounds like it's not filling up the steam boiler with water, no sound of the pump. Any tips? Thanks!

This is probably one best answered by Noids, but I made an attempt here: https://www.home-barista.com/espress...0.html#p706825

Help Please with a BES900 - I am hearing a clicking sound but no pump starting

I thought it might be the pump so I swapped it out for a new one.

Lights up and heats up no problem... just no pump

Any thoughts would be appreciated

Picking up a machine for repair is sometimes a matter of luck. I got luckier with a BES920 repair recently. Portafilter collar problem, which I managed to modify it to take a new 2 piece collar and the usual O ring changes.

I'm keen on picking up some parts if they are still available. Will send you a PM.

I would like upgrade brewing group to newer version from service kit SP0008924.

Anyone knows if this is universal part or it's 110V or 220/240V dedicated?

[level3ninja]

The red tips sticking out are the heating element, so it will be specific to one voltage only. The actual mechanical parts should be interchangeable, but the element won't be.

[Bacek]

But I did not saw nowhere information on that. It's low wattage so I thought it may be driven from electronics and not directly driven by mains voltage.

Ok I will probably buy it anyway. Then I'll compare heater resistance and depending on result use it or not.

I just hoped someone was doing it already and has some info on it.

[level3ninja]

It would be highly unusual for a heating element to be driven by ELV and much more likely that it is powered by mains voltage. I would advise you against connecting a different one regardless of the resistance.

[Bacek]

Anyway I found it. BES900/85.1 is 220V and BES900XL/85.1 is 110V. Generally part numbers with XL inside are US version parts. Attached document with other part numbers.

Bacek parts list has been moved to the appropriate documentation forum so others can easily find it.

Howdy all, I thought I’d post here and see what other BES900 owners have to say. Just last week I bought a BES900 second hand. It’s been beautifully cared for and I am super happy with it as an upgrade from Sunbeam EM6910. The steam wand is so much better, dryer and more powerful. And the whole group is easier to use and clean.

anyway, I see that the manufacturer intends for users to have it descaled only by the manufacturer. I have seen a couple of YouTube videos of ppl descaling themselves though.

I just wanted to ask for any hints and tips that users may have on doing the descale at home though? Taking the back off and detaching things patiently doesn’t scare me as I have done this on a friend’s 920 and also my 6910.

Also, I made shims from a cereal box for my 6910, and cleaned the group head regularly- any tips on whether the 900 will need shins as well and cleaning tips?

thanks!
