  I replaced the thermistors in mine and also the small control board. Its a similar age to yours. It was pretty easy and the parts relatively cheap. Theres plenty of info on the net about it. When i took the top off mine you could see where there was a steam leak around the thermistor in one of the boilers straight onto the pcb.

    Thanks, not sure if that is also my problem, online other people say ut might be the pump if I find other site of people with similar error codes.

    My biggest worry is I end up changing parts that didn't need to be changed then it costs me more in parts to fix when I could have paid someone to fix it for me.

  It doesn't hold pressure

  Change the seal, google it for part number.

    As above, I don't want to replace something until I know it actually needs to be replaced.

      Time to buy a new one. 🙂

        yeah or pay someone to fix it which hopefully will be the cheaper option.

        We paid pre covid prices and the cost of this machine has gone crazy the last few years!

            @boomramada: thanks, done. Now I just have to remember to check back on that forum and not be like the new users we get on Ozbargain!!

          @onetwothreefour: FWIW mate of my mine got their bes870 serviced through an authorized repair place then a few weeks later developed same issue again. Labour costs are through the roof these days, if doing it I’d prob see if they can give a definitive quote, and will guarantee the work.

            @Jimothy Wongingtons: yeah, I saw someone recommended on our local suburb facebook page recently, some guy who repairs appliances and is an expert at coffee machines apparently. Either way whether I repair it myself or get someone else to do it, I don't want to spend too much as it only cost $600 when we bought it, although to replace it with a new one is over $1k now I think.

  It sounds like the pump that delivers water to the coffee boiler.

  08:99 means 99 instances of error 08. So this is your most common error and sounds like the pump.
  10:39 is your next most common. Coffee NTC overtemp is likely to occur when there is no water in the coffee boiler. Again, sounds like the pump.

    Yeah I was leaning towards replacing the pump as that's what I found online on other sites. The pump seems to be about $90 tho, which is getting expensive if it's not that.

  Agree with looking for steam leaks too. If you remove the top and there is corrosion around the steam boiler and up into the PCB on the lid then you need to resolve the leaks and understand whether there has been any other damage as a result.

  Are you handy at fixing things? If so they are fixable, if not, it is most likely cheaper to buy a new one than pay a service fee + parts.

  Head over to the Breville owners group on fangbook. Lots of helpful people there if you want to have a go at fixing it.

  If doing the pump, consider brass pump with brass opv as an upgrade.

  Pump wiring is crimped, you would need new crimp connectors and a tool for crimping if you don't already have one. Jaycar sell a kit with the right connectors. The wiring is straight forward.

  I've managed to keep my bes900 going more times than I care to remember. Much of the time it's just replacing the original atop the boilers and in the steam valve. These often leak steam which can cause the triacs on top of the machine to trip the breaker if I don't catch them in time.

  Just be mindful if you are troubleshooting with the top off the machine, live 240v etc. Only do this if you are comfortable.

  If my bes900 dies properly, a new bes920 will replace it, as I understand they no longer use the orings on the boiler connections and they are much more robust.

  The water is likely running cooler from the head because you are measuring what comes out (which is cooling, not what's inside)

  5 years is the longest you can go with a proper machine, the seals are just o-rings which fail and leak, if you don't get it early the probes they seal in the two boilers will rust out and this is what causes the error codes.

  You can usually bring it back from the brink with just o-rings but a new set of probes may be needed, remove the top to see what looks rusty and replace that to start.

  I've had a 920 from new and its now done 12000 coffees and been re-sealed 3 times. New pump, steam valve, and still the original steam solenoid- but it's noisy. 920s are built like pro machines enough that you can keep them running with regular maintenance. It's not for everyone I know but people prefer to throw out the old and buy worse products new anyway… I wouldn't swap mine for anything other than a new 920.

  btw southwestcoffeegear are great for parts.

  I've also a used BES900 I rebuilt, it was used in a cafe and flogged, but I repaired it and it's perfect for the holiday house.
