If the water is not hot, it is likely your boiler’s water level probe. The cause of this is usually scale/mineral buildup on the probe. An out right failure of the probe could in more rare circumstances be the issue. Unplug your machine. Empty the water reservoir. Then fill your water reservoir with vinegar to the “Max” line. After that, have at least three big glasses or containers and plug your machine in, letting the vinegar get into your system, specifically your boiler where the water level probe is located. When the vinegar in the water reservoir looks like it is nearly at the bottom of the water reservoir level, unplug your machine and let it sit for at least 4 hours. After 4 hours, dump out the vinegar remaining and rinse your water reservoir thoroughly and then fill it with water. Get your 3 huge cups or containers again and plug you machine in and let the water displace your vinegar from your boiler. At the point you plug your machine in, it might just start working again and not pour water. If...
Likely not the pump. But before ruling that out completely, take a look at this video on Youtube for what is widely considered to be the most common problem causing the issue you describe: https://www.youtube.com/watch?v=bYyx8dWx...
Instructions state 100 percent vinegar up to the “Max” line for the BKC600XL model and a purge to replace the water with the vinegar followed by letting the machine sit turned on for a minimum of 4 hours. There is no need to unplug the machine for 15 minutes as the machine detects the need for descaling. If the descale message persists, you’ll need to run another cycle of vinegar through the machine. You can find precise instructions on descaling your machine on page 28 of your manual and the purge process on page 18.
Sounds like your magnetic sensor is stuck in the down position or malfunctioning. (1) Take a look in your water reservoir in the bottom front right area. You should see something that looks like a dark grey cookie (about the diameter of a 50cent piece (or looney if you’re a canuck). It will be vertically inside a clear slot and will float up and down based on water level. If that is stuck in the down position and does not float up to the top, Mr. Blinky Machine will go to town; (2) If the thin hockey puck has free movement up and down with water level changes, then the sensor inside the machine that detects water level, by sensing the position of the floatie cookie/thin-hockey-puckey thingee, could be having a bad day. Take a look there first and post a response. Once you’ve ruled that out the next suspect can be considered.
Wow, the only thing worse than no advice is bad advice. First and foremost, are you getting a “READY TO BREW” message? That would indicate both your boiler water level is sufficient and your temperature is sufficient. Secondly, lets clarify whether your several descales were done prior to the failure beginning or was it when the machine intermittently began working for a day outside of the weeks of malfunctioning? Thirdly, yes, @mbesho did correctly identify several of the key systems onboard your shiny BKC600/700XL precursor to Elon Musk’s Martian transport. Fourthly, the question you pose is where in the chain of command has one of the soldiers identified by @mbesho gone AWOL. You seem to be indicating this is an intermittent problem, although the way you have written your question, it could be a failure that began and persists unabated at anytime. I will guess you are saying it is intermittent that the machine works one day and then takes an unannounced and rude vacay for a few weeks. One unlikely...
Well, @kyle is in the ballpark, now it’s time to order some popcorn and crackerjacks. @m.d.decker, your pump is running constantly. A pump that is always on, or never on, depending on the machine, is usually a failed water level probe, reed switch, or sensor. When a probe, sensor or switch fails, it can be in open or closed state or it can just not be able to detect the correct condition, such as water level in the boiler in preparation for a next cup. This could also be interference with a probe/switch/sensor, a defective or ineffective (due to mineral build up or running it without water or ignoring a “descale” indicator message for example) water level probe is the more likely point needing inspection. As well, as another way of looking at this, Keurigs (such as the BKC600/700XL models) follow an algorithm of filling the boiler somewhat in preparation the next cup. It does this by: (1) Applying a 12 V signal to the aft pneumatic solenoid valve causing it to open; (2) Next, a 12 V signal is applied to...
Your pump is running constantly. You pump doesn’t seem to care what instructions you are sending to it, it just wants to make your water bill go higher. A pump that is always on, or never on, is usually a failed water level probe, reed switch, or sensor. When a probe, sensor or switch fails, it can be in open or closed state or it can just not be able to detect the correct condition, such as water level in the boiler in preparation for a next cup. This could also be interference with a probe/switch/sensor as well, but because your machine just runs out the gate like a racehorse being ridden by chupacabra, a defective or ineffective (due to mineral build up or running it without water or ignoring a “descale” indicator message for example) water level probe is the more likely point needing inspection. As well, as another way of looking at this, Keurigs (such as the BKC600/700XL models) follow an algorithm of filling the boiler somewhat in preparation the next cup.

Yep, @oldturkey03 is 110%. CLR will not only foul your machine, nearly permanently, but it will likely destroy sensors and corrode delicate components inside your machine. Breville recommends in their BKC600XL manual to purge the boiler of any machine that has been sitting for over a week. Breville also recommends descaling once a month by: # Dumping water out of the reservoir, and (1) Then filling the water reservoir to the “Max” line with vinegar; (2) Purging the system using vinegar (this will replace the water with vinegar); (3) Let the machine sit for at least 4 hours with the vinegar in the hoses and boiler; (4) After 4hrs, empty the remaining vinegar from the water reservoir and rinse the reservoir followed by filling the water reservoir with clean water; (5) Use the “Purge” method to empty the boiler and tubes of vinegar and replace it with water. If your BKC600XL is not producing full amounts of the setting you selected or it is very slow to start, the culprit is likely the plastic screen below...
