A drain cleaning machine with an electronic cable counter is disclosed which is of the character comprising a frame supporting a rotatable drum which is driven by a motor through an endless belt. The drum contains a flexible drain cleaning snake which is rotatable with the drum and axially displaceable into an out from the drum, and the frame supports a cable feeding device through which the cable extends and by which the cable is displaced into and out of the drum. An electronic cable counter is configured to count an amount of cable payed out from and retracted into the drum and includes first and second sensor portions mounted on the rotatable drum and a cable follower member, respectively to sense relative rotational movement therebetween. A process determines an amount and direction of relative movement therebetween and generates a signal representative of an amount of cable payed or retracted into the drum. A fixed receiver unit is mounted to the frame and includes a human readable display portion and a receiver portion configured to receive the signal generated from the processor portion.
