Breville's new dual boiler machine BES900

ajst2duk

The gap on my bench and the one in my heart is filled again - aromas of fresh coffee once again get the day underway at chez AJ All it took was two weeks, one star washer and a new knob, now the machine is able to bite as well as it barks - creamy espresso with fresh beans is now the fisrt morning task, one that brings great joy I'm hoping now that the warranty has nearly slipped by, that it all holds together, and delivers good taste for a few years to come AJ

must admit I missed this earlier, but pretty impressive Brett... I can feel a coffee poetry comp coming on!? A 😉

Morning all. Hope your mornings have been full of delightfully aromatic (and tasty) brown liquid ... I'm talking about coffee for those of us who are a little slower 🙂 I have a question that I posted on "the other" forum but I haven't received an answer so thought I'd ask here as well: Does anyone have any knowledge on how the hot water outlet is supplied with water or an internal schematic of the BES900? I ask this because I am getting hot water out of the hot water spout that has a light brown tinge. Is it possible to get rancid coffee through the hot water tap or am I seeing something else? I clear water back flush after every coffee making session and I do a chemical back flush every few weeks using caffetto. I also filter all the water that goes into the machine and have been vigilant to change the filter in the machine as recommended.

Once again I'm reminded how lucky we are to have members like AM on our forum. Now, who likes jigsaws... http://www.ereplacementparts.com/breville-bes900xl-the-dual-boiler-parts-c-116052_116055_187843.html

I dont know if they have it in Perth, but the Local Hardly Normals ( And DJ's) , have a Breville display of the internals of the DB. Its an "exploded" section of the m/c using actual components to show the water paths and the functions... very informative. Its been a while since i looked at it, so im afraid i wouldn't rely on my memory to describe the plumbing ( its complex ) I will bet you could find it on line somewhere too !

See this link and you will find the cut away and many other helpful images - http://coffeegeek.com/proreviews/firstlook/brevilledualboiler/details KK

Thanks for the help guys ... to be honest I am having problems figuring out how it is all plumbed together from the images you guys have found etc. I might go see if the local hardly normals has a cut away model that I can look at otherwise I think it is a trip to the service center. I did spend quite a bit of time cleaning it this arvo (did 2 chemical back flushes) and it did clear up quite a bit so that is promising but I still want too know if it should be physically possible for it to happen under normal circumstances.

The review says hot water comes from the brew boiler, there should be a 3 way valve between the brew boiler which prevents flow going from the grouphead to the boiler but I cant find it in any of the pics. Its possible something is wrong with the valve though.

Another new reliability issue has popped up on mine, just posting in case anyone else has had the same or similar. Now and then, the machine will short-shot the brewing, so with a consistently filled and tamped basket, extracted at 9bar, sometimes the double shot program will just cut the shot off at 15-16 secs. It started doing this very occasionally, but now that I'm over the 12 month warranty threshold, it's started to become much more regular. As you can imagine, the growing incidence of "sink-shots" has become annoying and expensive. There is also a new clattering noise which is starting to worry me, happened the first time when I was backflushing. I'm reluctant to send it once again back to the servicve centre for two reasons, potential cost and another major time out. I do like the machine and I so want to believe in this product, however I'm starting to lose confidence in it. I hope it doesn't just decide to turn up its feet and fail on me AJ

I'm sorry to hear this mate. We all want this machine to succeed! Lets hope it's just a minor glitch.

This goes to the question of longevity. Just days over a year old my machine seems to have a very poor water flow. Where it previously took not a lot of time to get to OPV level with a blind, it now takes a whole 15 seconds to get to OPV level. It's all clean, that's not the issue. Any ideas?

Hatchy

I called Breville who gave me an authorisation number as my receipt may have gone walk about. She was really nice on the phone. Actually followed me when I said things like group head and solenoid. I then called Mr Sparky's at Oxley who said their tech was on holidays till next week and that Sparky's at Albion was the authorised repairer for BES900 anyway. Sparky's Albion is on holidays (as you said AM) or at least not answering the phone. Interesting that Mr Sparky's whilst listed on the Breville site didn't want to handle the machine, rather direct me to another repairer. Horses for Courses. Thanks AM for your feedback.

Hatchy

You Beauty. Thanks for the heads up AM Phoned them and will take it in hopefully this afternoon if I can make their 4pm close.

How did you go Hatchy ? Ours in addition to the now regular short-shots (usually fixed by reprogramming) is making funny noises in the pre infusion stage with no pressure showing on the gauge where it use to show 3bar. With a blind it still gets to OPV pressure ok. I've reverted to using the manual shot as I got tired of sink shots where they were just the result of being cut off early. In each case the grind dose and tamp have remained consistent. I thought that this machine might have been the endgame for us for the next few years but its proving a bit of a challenge. I would rather hang on and manually shot for the time being instead of sending it off yet again to the service agent and have to pay for 4 coffees a day for two weeks.

Hi AM - yep mine has already had the o ring replacement - in fact the whole solenoid assembly was replaced as a little bit of o ring had blocked it. Mine is out of warranty now being one of the first - in fact serial number 00000001 so I will deal with issues myself as and when they impact our ability to pull shots - happy to do this and I'm sure that this forum will help us all share ideas and experiences. If I come across as a little grumpy about our machine - I guess yes - we were a bit disappointed given the cost of the machine to have had problems so early but it was always on the cards with a ground breaker like this. - cheers and happy new year everyone !! 🙂 AJ

Hi Guys, I picked up the machine today. 1 week turnaround. Speaking with the local repairer in Brisbane, they have stopped using o-rings after going through 3-4 types and now have a gasket instead. They replaced this in the main solenoid and upgraded the software and reset the OPV to 10bar (I did like the feeling of having it set at 9.75 by AM - something nice about it being below 10, but the guy did talk about the needle flutter issue that doesn't happen at 10 - I did want to say that it doesn't happen at 9.75 either, but in reality there is nothing to quibble about, and I was grateful they went that extra mile to reset the OPV) I'm happy, have only pulled 5 shots thus far today, and all have been great. Flow is back to normal. I liked the comment from the repairer - "this machine makes a great coffee, we had one this morning" - they actually real world test every coffee machine they repair! The repairer in Brisbane is excellent and treated my machine with a lot of care. AJ - As for having to buy 4 coffees a day - that's a bit extreme, try pour over / chemex for a week or mocha pot. Plenty of alternatives in the coffee scene at the moment and beans to suit. Might be worth investigating a bit more to see what the go is with this new gasket instead of o-ring replacement as to whether it will more permanently solve your issue before you buy a Bialetti to see you through the repair wait. The repairer in Brisbane is excellent and I'm sure would give you the time of day if you just wanted to ask about the defect. AM - you're welcome to look at my machine to see what was done. Anytime.

This is great info thanks - I may try a call to Breville to see if I can get the gasket and software update done under warranty even though its expired. Yes I'll take advice on the coffee side - or fund another service crew who have a quicker turnaround.

I haven't seen anyone post about the problem that I am having. On occasion, about 6 times in the last month, the machine has started making pulsed gurgling sounds and the temperature display keeps going up past 102 before I noticed then shut it off. All the buttons become non responsive and steam comes out of the hot water outlet when turned on. Obviously the temperature is going above its setpoint of 94. The first time that I noticed this noise, the machine was actually in sleep mode. I have to let it cool right down and purge all the steam from the water outlet, then cross fingers its usualy ok for a few days. Its currently at Mr Sparkys at Oxley for warranty repair. Its only about 5 months old, Breville told me to take it there.
