An automatic detergent and fabric softener dispensing system for use with a washer with cold and hot water input lines which are opened upon the actuation of associated solenoidal valves. The present invention includes a pair of cylindrical tanks. The tanks each have an output conduit each connected at first end thereof to a bottom of the associated tank and a second end thereof in communication with the washer. The pair of tanks consist of a detergent tank with an associated detergent pump situated in communication with the corresponding output conduit. Such pump is adapted to effect the transmission of detergent to the washer only during the receipt of an activation signal. Associated therewith is a fabric softener tank with an associated fabric softener pump situated in communication with the corresponding output conduit. Similar to the pump of the detergent tank, the present pump is adapted to effect the transmission of fabric softener to the washer only during the receipt of an activation signal. Control circuitry is provided for transmitting an activation signal to the detergent pump upon the first actuation of the solenoidal valves and further for transmitting an activation signal to thee fabric softener pump upon subsequent actuation of the solenoidal valves. Finally, control knobs are included for selecting the duration of the activation signal which, in turn, determines the amount of detergent and fabric softener is dispensed.
