The present invention relates to a programmer control device comprising a rotary cam block capable of being driven in rotation step by step by an advancing cam actuating an oscillating pawl carrier. The control device possesses means of blocking and releasing the action of the pawl, comprising a blocking lever 50' interacting with means capable of rocking the said blocking lever between two angular positions during each to-and-fro movement of the advancing pawl. In the first position, a part 51' of the blocking lever is located in the path of a slope 55 of the pawl 21, so as to prevent the action of the latter. In the second position, the part 51' is not located in the path of the pawl 21, so as to permit the action of the latter. Retention means, such as the nose 79a of a release lever 69a, which can be actuated, for example, in a delayed manner, are capable of retaining the blocking lever 50' in its second angular position counter to the action of the spring 49, to release the action of the pawl 21 at the end of a certain delay period. The invention can be used to control, in particular, a clothes washing machine or a dish washing machine.
