Washing system, server, control method, and program

The present application addresses the problem of enabling a washing machine to use information transmitted from a terminal device while the washing machine is not connected to a network. A washing system according to an embodiment has a washing machine. The washing machine is configured to be connectable to the network. A server is configured to transfer the information from the terminal device, and to hold the information transmitted from the terminal device when a response of the washing machine to the transfer is not detected. The washing machine is preset to start communication when a predetermined condition is satisfied, and to attempt communication with the server and connect to the network when the predetermined condition is satisfied in a state in which the washing machine is not in communication. If the washing machine connected to the network transmits the information held by the server from the server, the washing machine receives the information transmitted from the server and performs an operatio
