Hotpoint FDW80P Turbidity sensor?

Thanks ck. I suspect it is polarity sensative as the sensor consists of a transmitter and a receiver I.R Led, there are 3 wires on the plug One is common to both the transmitter and receiver and of the other Two One goes to the transmitter led and the other the receiver. But thanks for the suggestion anyway.

usually if they are not keyed/polarised they are not polarity sensitive so can go either way without any effect
