The error log in the Breville Machines is very useful in diagnosing faults. For some reason they are a secret and not meant to be disclosed. But it’s a poorly kept secret as I see them all over online forums. So not to be outdone I’ll mention a few of the common ones we see on the machines and what they tell us about the machine and how to get into them.

Error Messages that just appear

The most common error you are likely to see on the BES 980 is the “Err“, this may just appear and the machine will not function. You can turn it on and off, or bang the machine but the error will persist. It refers to the NTC on the steam wand being open circuit. You may be able to resolve this error by cleaning the wand or untwisting the NTC sensor. But this will only be a temporary solution. The steam wand is cactus and will need to be replaced.
There is one other code that may appear ‘Coer‘, this is a serious situation and will require a software update. Don’t worry too much about it I’ve never seen this error present.

How to Access the Fault Log

As Iv’e said these Breville Machines have a Black Box, well kind of, which can be very useful when diagnosing faults. To demonstrate it, a YouTube video would make life easier. But he’s my best written instruction. To get into the menu, with the machine off, but powered at the wall socket, press and hold the “one cup” and “two cup” buttons and then press the “power button”. You will hear a beep and the machine will enter Service Mode.

The software version will be displayed along with Fr.

Now you press the ‘Select’ Encoder button, it will be lit up. And by dialling through this you will be able to scroll through all the errors in the log.

There are 32 errors and they appear as the error number followed by the number of times that error has occurred. So the machine pictured below is showing error number 22 has occurred zero times. I will go though some of the important errors once I have told you how to reset the error list.

To reset the errors, simply scroll through errors right past number 32 until ‘ErSt’ is displayed, them press and hold the ‘select’ button for 3 seconds (it will be lit up) and the error log will be reset to zero, a beep will indicate success. This is useful if you want to capture a fresh fault. The cup count will not be reset nor will stored recipes be deleted.

The Common Errors we see in the Workshop

Error 23 – Coffee pump. This error indicates the coffee pump has been activated but limited clicks have been detected on the flow meter. So water is not moving. This is a common error associated with a failing coffee pump. You may also notice the pre infusion is no longer flowing. Replace the pump.

Error 26 – Steam boiler NTC over temp. This is usually associated with a leak around the steam probe. Steam venting from the steam probe insertion port will cause this issue. It may also be a more serious issue with the triac locked on and over heating the steam boiler. You find that the steam boiler thermal fuse is open circuit and needs replacing as will the triac board.
Associated with a Triac fault are high temp alerts for the coffee boiler (error 25) and block high temp alert (error 27. Remember this fault may present as the machine not reaching temp as a thermal fuse may be open.

Error 30 – Grinder Motor times out, often resolved by cleaning the tamp fan and cleaning the grinder, buffing the blades and re calibrating the grinder. This flag comes up more frequently as the grinders age. Replacing the grinder is the best solution. Consider this action after 6000 cups. replacing the grinder blades may also improve the quality of your coffee.

Error 20 – The steam pump is being activated but timing out as the high water probe on the steam boiler has failed to detect water (closed circuit). You will have a cold steam boiler. So check the steam pump is running by removing the high level (red) probe and listening for the steam pump to start. If it does check for scale in the inlet line from the steam pump. Finally the steam pump may need replacing. And of course clean your water level probes.

Error 21 – This error is usually associated with a descale attempt and it indicates the high level probe is detecting water but the low level probe is not. Clean your probes. Try flushing the steam boiler. This issue is usually resolved by taking these actions.
