![Breville Single And Double Filter Size Lights Flashing [Fixed] Breville's reliability based on the error-indicating system is so good. One of those systems is the light flashing on the machine. If your Breville single and double filter size lights flash and you’re worried about why is happening? Here is a quick answer. Breville single and double filter size lights flashing are safety measures that the machine takes to avoid brewing espresso. Because some coffee intake component is not locked correctly. You can fix this by taking away the hindrance blocking the machine from being locked. Further in this article, you will get to know more about these light flashes deeply. You will get to have a deeper insight into the reasons for these problems and also how to resolve these issues. So, make sure that you read till the end and benefit from the knowledge that I provide you about these problems. 3 Reasons For The Breville Single And Double Filter Size Lights Flashing 1. Coffee Grinder is Not Locked Properly The very first reason for the light flashes you are facing is that the grinder part of your machine is not locked properly. This grinder has two components, one is the burr grinder and the hopper of the machine. The most common thing that would be keeping it from getting locked is the coffee grounds stuck in it. This could be pretty annoying sometimes but is not that hard to fix this issue by yourself. 2. Issue With The Contact Pressure Switch The contact pressure switch is a part of the Breville espresso machine that regulates the pressure in the compressor. The issue with this component could be that the grinder’s hopper would not be perfectly locked in with it due to which lights would flash. This is a problem that would make the machine take precautionary measures because if there is not enough pressure in the machine compressor, then the espresso will not brew correctly. 3. Coffee Grinder Is Not Clean Sometimes, when the coffee grinder of your espresso machine is not clean, then the lights of single and double filter sizes could start flashing. This is mainly because the machine does not allow you to brew espresso because the dirty grinder could damage your machine. Solutions For The Breville Single And Double Filter Size Lights Flashing 1. Lock The Coffee Grinder Properly As explained before, when the coffee grinder’s parts are not locked correctly with each other, the machine will not brew any espresso. In this case, you can use a little amount of force to push the hopper and the burr to lock them to each other. If this does not work out for you, you can also disassemble the parts and lock them together manually using the physical methods. So, in the end, it is up to you what method you choose. 2. Engage The Contact Pressure Switch Engaging the contact pressure switch means that you will need to try and put the hopper and the switch in a lock that would make them become in contact with each other’s mechanism. You can easily see it by observing the locator pins of the switch. In this case, if the switch is not locked in with the pins, it will slide over it. You can easily lock it with the pins and engage them by simply taking them back and sliding them together again. 3. Clean The Coffee Grinder The Breville espresso machine’s grinder could also need some cleaning if the lights on its filter sizes start flashing. You can easily clean it by following the steps given below; First off, you will have to unplug the machine and remove the container in the machine that holds the coffee beans. In the next step, you will have to get rid of any coffee residue in the container. You can use warm water with a nylon brush if you want, or you can also use a vacuum cleaner to suck out the dirt and residue. After this, you will see a socket in a hexagon shape. Remove it and use the same method as before to clear out any remains or residue. After everything, at the very bottom, you will see a small ring with a cloth on it. Remove it and use warm water to clean it. In the end, you have to put the machine back together and voila, you can plug it back in and start brewing all the espresso you want without any light flashes. Are Single And Double Filter Lights Flashing A Major Issue? The single and double filter size lights’ flashes are by no means an issue. These lights are the safety measures taken by the Breville espresso machine to tell you that the functionality of the machine will not continue because the machine would get damaged. It may seem like an issue, but it is more of a safety check to keep your machine maintained and away from any kind of damage. So, do not get worried or anxious whenever you see such a sequence on your machine interface. Why are the lights flashing on my Breville coffee machine? The light flash sequences represent different scenarios in a Breville espresso machine. If you are doing a cleaning cycle, the machine will flash because it is telling you that the cycle is underway. But, if there is no cycle running, then it could mean there is something wrong with the machine. It could be some safety measures being taken by the machine or a warning like the need for descaling, etc. Directed towards the user. So, watch what issue you have before referring to any place. Why is the power button flashing on my Breville dual boiler? The power button on your Breville dual boiler represents the process during which the temperature for your boiler is reached. Once the temperature reaches the optimal level, then the power button will stop flashing. This is not an issue, rather, just a way of a machine that tells you about the temperature condition of the machine. How do I stop the flash from descaling? If the descale light on your Breville espresso machine is flashing, it means that it needs descaling and cannot operate without it. In this case, the only option that you have is to descale the machine. You can easily do this by first rinsing the machine with warm fresh water and after that using a descaling solution to start a brew cycle of the machine. In the end, rinse the machine again with some warm fresh water. Conclusion Breville coffee machine provides you with many features including the filter size selection. But, if they start to flash all of a sudden, you would certainly get worried. But, fear not, those are not some errors that could damage your machine. They are just safety measures. You must follow them to maintain the functionality of your machine. If you are observing one right now, just use my guide to walk yourself through it. Now, what are you waiting for?
