Water dispenses automatically without heating
When the unit is turned on it immediately starts dispensing water while saying heating and won't stop unless you turn the unit off
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. It does this by:
After all this, a process will begin whereupon other valves are opened by application of a 12 V signal and only then will the boiler be activated to push the temperature up the PID controlled temperature as designated in the digital menu on the machine. Once that temperature is reached the BKC600/700XL models will indicate on the screen that it is ready to brew.
So there’s your most likely problem then . . . a faulty water level probe. This could be caused by a bunch of things, but scale/mineral buildup is the likely culprit. You are going to have to take advantage of your on off switches/plugins and careful timing. Try this:
Good luck! Report back for all to see for future fixes if it works.
