Abstract: A dispenser of washing agents for washing machines has a first tank, to contain a first washing agent, and a first dispensing arrangement, to dispense first dosed amounts of the first washing agent. The first dispensing arrangement has a peristaltic pump, which is configured to be driven in a first direction of rotation to cause delivery of the first dosed amounts of the first washing agent. The dispenser has a second tank, to contain a second washing agent, and a second dispensing arrangement, to dispense second dosed amounts of the second washing agent. The peristaltic pump has a command arrangement of the second dispensing arrangement, and is configured to be driven in a second direction of rotation, to drive the command arrangement so as to cause dispensing of the second dosed amounts of the second washing agent.
