An agent dispenser for a fabric treatment appliance includes a housing having a manifold and an agent compartment. The manifold may be configured to receive water and supply the water to the agent compartment through an outlet port. The agent compartment may be configured to receive an agent, such as a detergent or additive, in liquid or powder form. The outlet port may be in fluid communication with the bottom of the agent compartment to supply the water to the bottom of the agent compartment whereby the water supplied to the agent compartment mixes with the agent in the agent compartment substantially from the bottom up.
