On most vehicles, the wiper fuse also serves for the washer pump motor. Not too sure about Peugeots, though. Just check for power at the pump motor connector, with key on and lever/switch pressed for the washer. If the wire has power, it is the motor or the ground for the motor. If there is no power to the pump motor, check the washer switch. There should be a hot wire going to it with the key on.

Most likely the pump (motor) is gone and needs replacement. However, it is worth checking that fuse allocated to windscreen washer is intact. Furthermore, you may also need to check the wiring for flow of current at lever end (handle on the steering wheel) and wires connecting to pump on the water reservoir.

check where you took the power source,,, sounds like wrong place
