Adding more water … ?
If you look up the help Keurig provides on this issue they pretty say … “just add more water”. But lets assume you have done the obvious and so this answer really is that helpful. Hopefully we can provide you with something more useful …
Cause of the Problem
Keurig are right in that the brewer worked out that it needs more water in the reservoir in order to carry out the brewing cycle you have asked for. The machine measures the water level through a magnetic sensor installed in the body of the brewer, matching this to where the floating magnet is in the reservoir itself.
As you can see in the two photos below, with the first showing the magnetic sensor on the side of our B60 and the second the corresponding magnet in the water reservoir.
When the brewer cannot gain the correct reading from its sensor the logic board thinks, well I better tell the user to add more water. What it can’t work out for itself is if there is anything wrong with the sensor, the magnet or the signal.
Solution 1 – Floating Magnet Check
Check to see that the magnet in the water reservoir can freely move up and down. They can become stuck through build-up or other obstruction. If you need to take the magnet out there are a couple of screws at the top of its casing; remove these and wash out the plastic cradle it sits in.
Solution 2 – Magnet Sensor Check / Replacement
If the floating magnet is working ok the next step is to look at the sensor itself and check that it is connected correctly, with no broken wires.
Rather than go through all of the steps here, check out our dedicated guide to checking the sensor. This guide will take you through all the necessary steps, along with full description and photos.
