BES920 (Dual Boiler)

This is actually for the BES900. This is a loan machine and I can only sometimes get the right pressure on pressure gauge when making a coffee. They did not give me the proper tamper but I have a stainless steel measuring cup which seems pretty close to the right side. I’m using espresso coffee and I tamp it down as firm as I can get it. Today’s coffee only just got past the pre infusion bar. Help please!!

Hi Kathy, I have only had this issue on my old machine also the BES900 when the seal wasn’t fitted correctly. It would never reach the desired pressure and I finally gave up and sent it away - the result was that at manufacture level the seal was faulty. You can try to clean the machine, do a factory reset and play around a little with the grind though - it could be a mix of those factors also. Good luck

@AdrianandShel i am having the same problem, im thinking mine is the seal are they easy to replace?

If it was the seal it is likely it would be leaking out the sides. If you are using pre-ground coffee it is likely to be too course unless you are using a dual wall filter.

BES920 (Dual Boiler)

Machine keeps telling us to descale. This is after maybe one or two days after doing a descale. A good many of the questions/answers here are a bit confusing so can anyone give some possible reasons that I might attempt before chasing Breville. After a descale the machine appears to function ok, it is just that the descale message keeps popping up within a very short timeframe. Any ideas?

Hey, I had a similar experience, before contacting breville try to do a factory reset on the machine - it is found in the manual but I can’t remember what page sorry, good luck - check back in and let me know if it solves your issue :)

BES920 (Dual Boiler)

Has anyone had the pressure guage malfunction after doing a brew-head clean cycle? We just did our first clean cycle on our BES920, using the supplied cleaning tablet and following the instructions in the owners manual. Now the pressure guage does not seem to work. The machine still seems to work fine...still brews coffee and steams milk, but the pressure guage either doesn't change at all, or will jump to like 5 mbar and stay there, even when the machine is off.

In the questions in this forum I saw a lot of folks having issues with the descaling process, but not with the cleaning...has anyone else experienced anything like this with regards to the pressure guage after a cleaning cycle, and what did you to do to fix it? Do we need to replace the pressure guage?

My bes920xl blowing more pressure on group head, steam wand and in hot water outlet when I opened it , but less water coming out. And when the temperature reached 93 degrees the lcd never stop blinking. What's wrong with it? Is this fixable?

Hi, I bought the bes920 a year ago, love it. Just recently it's taking a lot longer to reach temperature of 94° - just hovers on 92°. Sometimes it hits temp, sometimes I have to turn off then on and shortly thereafter it reaches 94°. Any ideas?
Thanks

BES920 (Dual Boiler)

Just after some advice on grind size? I only seem to get a nice extraction when I grind my fresh beans at grind size 20 on the smart grinder if a go finer the extraction is very slow and only pouring about 15-20 ml of coffee with pressure at 10-11 bar and help would be appreciated cheers adam

i've tried 24, 22, 20 & 18...whilst i find no issue with the actual extraction, i found the taste seemed best at 20.
But i do know that going finer than 18 does result in slow extraction as the grinds are too fine & inhibit the flow of water.
But also, over-tamping will also cause the pressure to be high & the extraction slow due to denser grinds in the portafiller which also inhibits flow.
So perhaps in your case you are simply applying too much pressure when you tamp the coffee down?

I hope this helped...

Adam
Adam

Hi moose thanks for the tips, I definitely think that I am over tampering,I have found that the campos beans I have been grinding will only extract from the porter filter if I grind the beans at 20, however I brought some fresh beans from my regular cafe and am getting a really good result with grinding on 12-14 with a 30 sec extraction so maybe just different beans require more coarse grinds, only new to the barista game so still learning is this common with different beans?

My machine wont build pressure despite many attempts. The water filters through fine but the pressure gauge only moves marginally. Am I prepping i correctly. I am grinding the beans at 3 or 4. Is there somthing I am missing?

Hey Tracy. It would seem that you maybe grinding your beans to coarse.
I have mine set on 16 while the grind time is about 11.
Maybe start from there and adjust accordingly.
All the best.

I have tried a few different bean with different result. One of them also cannot build up enough pressure like your situation. Try different grinding size. What my experience was some beans do need a very special grinding size (very big different to the others) to have the pressure correct.

BES920 (Dual Boiler)

Our BES 920 is a great machine and the shower screen cracked so Breville sent me a new one at no cost and no fuss.
But..the only bugbear I have is when you fit the handle into the group head the two spouts are at an angle to the tray making it awkward to line up two cups.
So my question is, is it possible to rotate or remove and re-align the spout so it is aligned with the machine?
I am a habitual DIYer but always like to research before I dive in.
Any advice would be appreciated.

BES920 (Dual Boiler)

This is our 3rd Dual Boiler - the two others both replaced under ext. warranty. 1 under "lemon" clause (too many repairs) - 2nd because the ext. warranty we took out replaces the item if the repair takes too long. Anyway - our 3rd machine is not behaving in the same way as the previous two. It gets up to the optimal pressure initially - but after that, for the rest of the pour the pressure continues to drop - sometimes down to 3 or 4. Obviously we are are doing everything the same as we always have (same beans [fresh], same tamping amount etc.) We've played with the grind fineness and amount (as we have done MANY times before), so just wondering if we should be taking our (month old) machine back. I have a nasty feeling they are going to blame user error which is why I'm stressing the point that we've had nearly 6 years experience with the same (model) machine. Any thoughts? Anyone with the same issue?

I have a breville BES920. Two days ago I completed the descaling process. The manual had instructions, however it said to follow instructions of the descaling product, which was included in the purchase of the machine. The descaling was successful however it is still saying descaling needs to be completed. Please advise how to remove notice?

OMG!. I I have not yet been asked to descale and until I read your question I didn't know I would have to. I will have to buy some descaling solution. I can't find in my Breville book how much solution to use when the time comes. As for your question it just says to Press the Power button to exit the descale mode but you would have already read this. I hope it's am easy task when I get to do it. So sorry!

I had exactly the same problem with my BES 920. Ran through the whole descale process (firmware v3) and still got that pesky descale message! Read all the posts and resetting the machine was the common theme. Tried resetting - didn’t work. After my third reset attempt I noticed that machine still had the correct time of day...which I thought was a bit strange after a full factory reset. Turned off the machine at the wall for 30 seconds and still got the message and the clock time was still correct. I figured that the machine must have a short term memory (capacitor?) so this is what I did:

1. Switch off machine at the wall
2. Wait ten minutes
3. Switch on machine at the wall
4. Do a full reset (instructions easy to find online)
5. Descale message gone! (Don’t forget to reset your clock, auto start etc)

Yep. Both Breville and Bravo repairs didn't know and wanted to charge me to fix this. So well done Ian.

BES920 (Dual Boiler)

I have the BEP920 in black and have little flting ants in my water holder at the back and have cockroaches nesting somewhere in the top, similar to others with the ants. Also the black paint on the machine has been bubbling at the top around the edges of the flap which you press to put the water into, I have rung the service centre and the machine is less than one year old, so well within warranty time but my question is, is the paint bubbling a design fault because if so it would seem rather futile having a new piece put on (which is what the service man said they could do) if the second piece is likely to bubble. Has anyone else had their plaint bubble? Thanks

BES920 (Dual Boiler)

Hi there - Another issue after descaling my breville bes920. It was working perfectly before machine indicated a descale was due after 2-3 years. I followed brevilles guidelines exactly and after descale the steamer will not function/heat - 3 dreaded beeps! I Contacted breville and they instructed me that there was probably an air lock and to drain the steamer tank, leave valve open for 3 hours then close. I did this twice and the second time left it overnight to drain but still the same problem. I contacted breville again and they indicated as it is out of warranty there is nothing much they can do........ From what I am reading this seems to be a very common problem and it appears that there may be a batch software fault or similar! any help appreciated?

If the problem was reported prior to warranty expiry and not resolved the warranty remains valid for the problem. You might need to unblock the steam wand holes.

Greenhills

Steam wand definitely not blocked. I actually spoke to the Breville Service agent here in Adelaide to see if it was worth repairing and I was directly informed that there is a known software issue with these and that the thermofuse blows after descale. They advised me that if the thermofuse was replaced and software updated then this would stop it from happening again. I have now contacted Breville service centre and advised them of this and am waiting to hear back with the outcome.......

Hi,
Because the problem started after you descaled the machine, it is related to the steam boiler. The corresponding screw to draining this boiler is the one on the right.
To make sure that the boiler is filling up with water, follow the descale procedure by pressing and holding the single shot button before pressing the power button. navigate to the dESC setting and press the menu button. You should hear a click sound and the display screen is blank.
Make sure the tray has been emptied and remove the silicone tab from the boiler screw recess at the bottom right. Open the boiler drain by turning the right screw anti clockwise. Make sure there is a damp cloth covering the right side of the tray cover, because there may be steam released from the boiler drain.

This next part is different from the user manual.
Empty all the water from the water container and remove the filter from the container. Fill the container half with white vinegar (just a woolies brand is fine). Add a Hillmark Expresso Kleen sachet coffee machine cleaner from Bunnings. About $7 for a pack of 3 sachets. Dissolve the sachet in warm water and add to the container, continue to fill up the container with water until full. Turn on the machine. Once the machine reaches 93 degrees, open the steam wand. Don't worry if it bleeps. The hot water with the cleaning solution will find its way into the wand and other parts of the boiler. Leave the wand open and wait for about 10 minutes. If nothing happens, close the steam wand and wiat another 5 minutes. Open the wand again and leave it open for about 10 minutes, or until steam is coming out of the wand. Repeat running steam through the wand and other parts of the machine, including the group head and hot water spout.
If this does not produce any result, your steam boiler will have to be replaced. (Still a lot cheaper than a new machine)

BES920 (Dual Boiler)

For the last couple of months I've been unable to get good results from the steam wand. The milk heats up too quickly and boils before I have a chance to build any volume (the jug becomes too hot to handle after about 5 seconds). The machine also seems to stay very hot, even after unplugged. When it is on the warming area at the top is too hot to touch. Any ideas what might be wrong, or am I just imagining things? Thanks.

The jug feels hot because the end of the steam wand is too close to the jug bottom and your hand. If its heating the milk too quick turn the steam power down. Tje machine will stay hot for some time, it cools slowly.

There are 2 boilers in this machine. One is for the hot water, which has been factory set to 93 deg and can be changed in the settings. The 2nd boiler is for the steam wand and is fixed at 130 deg. It sounds like the steam wand is getting too hot, which is strange. Maybe it is due for a good descaling. (See your manual)
The plateau on top of the machine is designed to get heated. This is so you can heat the cups you use for your coffee. As the boilers heat up, this area can become quite hot to the touch.
I use a milk thermometer for the milk, so the temp is always around 65 degrees.
When heating the milk, make sure the spout sits just below the surface of the milk, near the edge of the jug. This will generate a maximum amount of micro bubbles - great for your flat white. Keep ithe wand in the one place, try not to move it around.
Hope this is helpful.

BES920 (Dual Boiler)

My BES920 has been descaled. Problem is my Steam is not pumping, the steam boiler gets the water but there is obviously no heat and as such (I assume) there is no steam (there are 3 beeps though). Does anyone know how to fix this or is it that the heather in steam boiler stopped working. Also, I used to have only POWER button illuminated and now All 4 of them (Power, Manual, 1 Cup and 2 Cups). I am sure after the descale something hasn't been completed and lights are still on. The following day I have repeated the process as per the instructions but still no luck.
Thanks, Ed

If the steam boiler worked immediately before the descale process but not now then you are probably correct and the software still thinks its in a descale process. When I descaled it took me a few goes to complete the process. Have another go at trying to complete the descale. turn off and disconnect from the power to reset the machine. If none of this works then you can call Breville to try and resolve it or you'll have to take it to a service centre.

Thanks Tangent,
I have tried everything including full descale 5 times but it still thinks its in the descale mode. Did power reset, than reset of the machine itself (water hardness) and still nothing. Spoken with Breville and they say there is air block somewhere and machine needs to be unblocked. Tied all the suggestions but still no joy. It seems it will need to go for de-blockage at breville service.
Thanks Ed

BES920 (Dual Boiler)

Hello,
I have a problem with my dual boiler. There is leaking steam from the drip tray and the machine does not heat up to the full temperature. It stops at about 80 C. Could it be that the small boiler (100W?) below the main boiler is broken? Steam on the right works fine.The Steam goes into the drip tray on the left (!) I really need some helo to get it fixed. Maybe another one has the same problem with it.

I have Dual boiler 920 for about two years now. It start leaking water from the opposite side of the steam. This only happening while the machine is heating up. The water stops after it reaches the desired temperature. Also the first shot or despised water from the group head take about 12 second till water come out. Any ideas?

I've had this same problem for a few weeks now. Pulled out the tank. Nothing obvious. Let the machine cool down, removed the drip tray, and turned it on to heat up. Leaking on the left side. Must be a worn gasket in the boiler? I put in a request ticket. I hope I don't have to send it in for repairs, but I doubt any of the faulty parts are home serviceable. Good luck.
