just got a replacement mains filter for a dishwasher and am a little confused as to the wiring. it is not a direct replacement for the one already fitted. it has four tags two labelled L and N which are self explanatory but the other two are both labelled U. Does the U mean unfiltered input?
It would help if you told us the manufacturer of the filter and some model or ID info.

Hi! If this is a european unit L and N are the mains input U and U the output into the machine. Thus the U opposite the L gets the brown wire and the U opposite the N gets the blue wire (if the machines internal wires are so coded). Important: The filter case usually gets bolted onto the frame of the machine (safety earth). Note: If you aren't comfortable with domestic appliances, I suggest you employ a qualified electrician, as the voltages found inside appliances are quite dangerous - their fees are based on having discovered this fact painfully ;-) Good luck, Pierre.
My vote would be that L and N are line in and U/U are line out to the apparatus.
NPAul:
I completely agree with NSM.
