-ABSTRACT- An electric drip coffee maker hot water generator wherein a unique self-cleaning water channel construction is provided in an aluminum casting. A plurality of transverse lands and grooves are formed in the walls of the water channel so that mineral deposits that build up on the lands and grooves and other surfaces of the water channel will crack off or flake away in relatively small chips from differential thermal expansion and contraction. The small chips will be flushed through the channel and into the coffee grounds.
