My Keurig Elite B40 has stopped working. Even after filling the tank and adding the k-cup the ADD WATER light starts to flash, I can hear it running but its not drawing water at all. I have cleaned and inspected for any blockage, the magnet is moving as designed so at this point I dont know if maybe its the pump??
The problem Janice explains in her email is not uncommon with the B40 brewers. As much as we like the older machines, that many many people are still using, the pump failure must be one of the most common faults we see with these units (in particular for the B40 and B60 brewers).
Janice is most likely right when she asks if it is the pump that is causing the problems with her B40. In particular it is most likely the water pump (as shown above), which is used to draw water from the reservoir and into the boiler unit. It’s the air pump’s job then to bring the water out of the boiler unit and through the K-Cup and into your coffee cup.
Before getting stuck into replacing the pump a technique that some of our readers have found works with faulty pumps like this is the Keurig Burp. By providing a firm slap to the side of the unit this can sometimes get the brewer back into action (if only for a temporary solution). You can find more information about this in our short guide to the burp.
If this doesn’t prove successful then the next step will be replacing the water pump. Again, we have a repair guide that will take you through all the steps necessary to replace the faulty pump with a new one. We also have Keurig parts replacement page that you might like to check out as it provides you with links to buying various parts that fail on these machines, including pumps.
