Breville Precision Brewer Error Codes and What They Mean

Did you know that there are many factors when it comes to brewing? The brewing technique, the amount of coffee, the duration of the brew cycle, and the water itself. Even pre-infusion, which simply means soaking the grounds at the start for uniform brewing, can help improve the flavor of your cup of coffee. It is simple to see why brewing is referred to as a trip by coffee specialists.

The Precision Brewer, Breville’s newest drip maker, allows you to experiment with several of these options. You also might say the coffee maker possesses superhuman abilities. I had a clear road ahead of me now: keep tinkering with the Breville until I discovered the temp that I felt was ideal. I kept tinkering once I found it, separating additional factors like pre-infusion and testing the impacts of different brew rates. Finally, I discovered that 205°F, a minute-long pre-infusion, and a rapid brew pace were the right temperature for the Herkimer beans.

The Precision Brewer has additional great features as well as a few flaws. First, the positive. The brew temperature is not just high, but it is also constant, which is something that lesser coffee makers deal with. All original versions with glass carafes heated from underneath should be replaced with the insulated carafe (all of them, not only Breville’s).

The carafe also has two praises. it doesn’t drip when pouring and it has a big sufficient mouth for a hand to go inside to wash it. Cone brews for half a pot and basket brews for a full pot are both possible thanks to a smart detachable cone filter insert: extremely elegant.

On the downside, there is no holster for the measuring scoop that comes with it, which seems like a no-brainer, but we should be weighing our beans anyhow. It might be a bit tricky to line up the brew basket with the carafe.

The error notice on the display of the first device I examined was the main issue. A frustrating and perhaps catastrophic defect. This was especially frustrating because the diagnostic manual only discusses probable explanations for problem codes 1 through 5.

When I inquired about this, a business representative initially stated that the machine was "operating on the hotter side," but then suggested that it may be related to a light sensor. Nothing would trigger me to hurl my coffee maker out the door more than constant error warnings at 4:00.

Breville Precision Brewer Error Codes

Before we begin, you may get a PDF version of the Breville Precision Brewer User Manual by clicking here:

Breville’s call center line is 1-866-273-8455, which is open from 8 a.m. to 5 p.m. Pacific Time Monday — Friday. Dial 1-855-683-3535 if you are in Canada. The user handbook explains the error codes. You will also observe that there is no "Error 6." The user handbook covers Errors 1-5 and 7, but there appears to be no Error 6 to be concerned about.

Err1, Err2, Err4, Err5

Error with the internal system! Unplugging the item appears to be similar to rebooting your PC when it malfunctions, and in computer terminology, this appears to work very frequently. I am hoping that rebooting the coffee machine would solve the problem.

If you are at a loss for what to do and don’t want to call, follow the steps on page 18 of the user handbook to factory restore the coffee maker. The factory reset will erase any personalized settings you have stored, but it could perhaps solve your "Err" issue.

  1. This will return the machine to its original factory settings, along with the water hardness.
  2. Hold down the START, SELECT, and AUTO START buttons simultaneously for three seconds.
  3. To begin, click the SELECT button when the LCD displays “rES” (flashing).
  4. The following step asks if you want to acknowledge by saying "yes" or "no."
  5. Rotate the SELECT dial or button and push it.


If your Breville Precision Brewer is giving you Error 7, it is possible that you are not cleansing and/or descaling it sufficiently. All coffee machines, regardless of brand, type, or cost, require constant descaling. Breville’s descaling methods (page 18 of the user handbook) are as follows:

  1. The descaling cycle takes around fifteen minutes to finish.
  2. Remove the tank and empty it.
  3. Follow the maker’s directions to make a descale solution. Fill the empty water tank with this solution.
  4. Insert the carafe and the basket underneath the drip stop outlet. Ensure the carafe is empty and the lid is securely locked.
  5. To begin the descaling cycle, hold down the SELECT button for three seconds.
  6. The LCD will display “dSL” for 60 seconds before displaying the time remaining of the descaling cycle.
  7. The LCD screen will return to the main menu after the descaling procedure is completed.
  8. Invert the machine and brew with new water twice to thoroughly eliminate remaining water in the tank.
  9. Remove the water from the carafe and discard it.

It is a little strange that they state "make a descale solution according to product’s recommendations but then don’t provide any directions for the descaling solution! Breville’s descaling guidelines PDF page even states the same point. A 50:50 combination of water and distilled white vinegar is a standard descaling solution for most coffee machines.


On page 5 of the user handbook, it says: Before using, fully unwind the cable. Do not submerge a cord, plug, or item in water or any other liquid to avoid fire, electric shock, or personal harm. Allowing the cable to dangle over the edge of a bench or table, touching hot surfaces, or becoming tangled is not recommended.

It is suggested that you examine the appliance regularly. If the power supply cable, power plug, or item becomes destroyed in any way, do not use it. In a nutshell, ensure the power cable isn’t damp, broken, bent forcefully, or tangled in any manner.

“If an extension cord is used, (1) the marked electrical rating of the cord set or extension cord should be at least as great as the electrical rating of the appliance, (2) the cord should not drape over the countertop or table where it can be pulled on by children or tripped over unintentionally, and (3) the extension cord must include a 3-prong grounding plug” says the manual on page 6.

To put it another way, use a three-prong extension cable. If you get "err3" when using an extension cord, try replacing the extension cord. Although it appears to be a long shot, who knows.

“Do not use an adaptor or modify the plug in any way. Do not connect the appliance to an external switch or device (such as a timer, monitor or remote circuit) that can be switched on and off,” on page 7.

I am not certain why someone would have to use an additional timer with the Breville Precision Brewer because it is customizable. However, if your Breville is connected into anything other than a power outlet, it might be the source of your issue.

This being said, if a $300 price sticker, which is expensive but not insane when contrasted to other functional brewers, doesn’t upset your pocket, and you get thrilled by the prospect of a possibly long trip toward a flawless cup, then the Breville is the brewer for you. Collect some freshly roasted coffee beans, isolate a variable, and relax.

I read a few comments that said the user could not figure out what the problem was. One review said that they read the handbook completely, followed all of the troubleshooting steps, and set the temperature to its highest setting — 204 degrees Fahrenheit. But it was just not up to the task. Nevertheless, I hope the tips I provided in this article help you out!

In conclusion, this coffee maker is a high-end multitasker, and it comes with a nifty mini digital display that shows you what the device is up to. This is when the error messages come into play. Because it is digital, you will be notified when anything unexpected happens. It will, at the very least, try. Thank you for taking the time to read this article.

I am afraid I don’t have any quick fixes for each of the Breville Precision Brewer problem codes, but you can go over the user handbook to get a general understanding of what each code number signifies.
