In this guide, you will replace the mini pump. This is necessary if the Keurig is leaking or if liquid is not dispensed properly.

Why remove the circuit board?
Exactly my question ;)
Link to a new pump please
I agree. Why take out the circuit board. On the older Keurig models it was necessary to obtain access to the minipump, but for the 2.0 once the casing is completely removed access to the minipump is simple. However, if due to the failure of the minipump the pressure sensor ended up getting wet, then there might be a reason: to replace the sensor. There are videos claiming that 0V (0mV in this case) is the right output for the sensor. Not so, the correct output should be around 40mV when the pressure is zero. To test this, attach a voltmeter across pins 1 (-) & 3 (+) on the circuit board (pin 1 is above where the tube goes into the circuit board on the upper left side, 3 is upper right side, pins 4, 5, 6 on the bottom. Spec sheet for that device (FPN-07PG) is at https://www.fujikura.co.jp/eng/resource/.... With the tube disconnected, it will read ~.040 V. If it doesn't, try adding or subtracting pressure using a syringe--the voltage output should change.
