A washing apparatus such as an automatic laundry washing machine includes a wash agent dispenser drawer including an additive compartment for storing various additives such as detergent, bleach and fabric softener. One or more water inflow tubes may extend downwardly into the additive compartment and may be configured to deliver water for diluting the additives contained in the compartment. The inflow tubes are of sufficient length to reach a sub-surface portion of additive held in the compartment. Water may simultaneously be delivered to the surface of the additive. Furthermore, inflow tubes have their outlets positioned adjacent to the base(s) of one or more siphon post/cap assemblies located in the additive compartments, such that a churning effect is produced from the injection of water through the tubes and the siphoning action of the siphon post, whereby mixing is enhanced and additive buildup may be avoided and/or removed.

A chemical solution dispensing apparatus uses a dissolving tank to hold a solid chemical cake. The dissolving tank delivers the chemical solution into a holding tank by gravitational flow and then to a receiving system. A liquid level sensor in the holding tank senses the liquid level of the solution and calls for water delivery through a conduit into the dissolving tank. When the level reaches a low point a circuit opens a inlet flow valve to deliver water into the dissolving tank. When the level reaches a high point, the circuit closes a safety shutoff valve in the conduit line. A pressure regulator and control relay enable the conduit line to be properly pressurized by an inlet source of water through a shutoff valve that is normally open. When the level in the holding tank rises above the high point, an alarm signal is released to initiate an audible alarm.

An automatic washing machine includes a wash additive dispenser for dispensing detergent and one or more additives into a wash tub. Water is delivered to a first wash agent chamber in the wash additive dispenser for delivery into a wash tub during a wash cycle. Water is subsequently delivered to a second wash agent chamber to flush from that chamber any unintended collection of water or additive residue therein, as may result from the water delivery to the first wash agent chamber and/or from an earlier dispensing of additive from the second wash agent chamber.
