How do you get your hands on the tools to remove the bottom of the pot? (HB40616)That big hexnut inside, and the weird “screws” with two holes on the outside bottom? That said, cleaning the well did nothing, 4 minute peek instead of seven, 157 degrees. Warming light has been dimming, is that a sign? Just bought a Farberware to replace the Hamilton Beach: burns the heck out of the coffee, even smells burnt. Thanks
