There are various reasons why your front windscreen washers wouldn't work:
Fuse gone (in which case your rear wouldn't work either as it's a shared fuse AFAIK).
Washer motor pump gone (most likely in your case as you say you cannot hear the motor anymore).
Blocked or disconnected pipe (if it's blocked you'd still hear the motor/disconnected then you'd see a puddle of screen wash eventually appear under the car).
Blocked return valve (usually still get a dribble from the washer jets) or simply no screen wash in the reservoir (you've already checked that & topped up).
There are separate washer motor pumps for the front & rear windscreens fyi.
The pumps are both fixed to the washer reservoir located on the drivers side in the lower bumper section just in front of the wheel/tyre behind the wheel arch liner. If you cannot hear the motor running then it is most likely the pump motor has died imo.
I went through 1 front windscreen washer pump motor & two rear ones during my Zed ownership (fairly common especially as the 350's get older). It's a fairly simple job to replace them although it can get a little messy if you've a full reservoir of screen wash.
You can get the washer pumps (both front & rear) from various places but I've found Clark Motorsport (a trader on here although other traders are available) to be very good & fairly priced.

Also I forgot to mention: the tubing & the non-return valve for the front windscreen washer jets are located underneath the windscreen scuttle panel. You can get at some of it from inside the clutch/brake reservoir cover location although I still think the pump is your problem.
Hope that helps.
Looks very good, ...be interested to know what garage floor paint you've used and if it holds up.

Yep he is BM but I know last time I spoke to him he was winding it all down & literally had just sold his last 350Z LED bulb kit.

He's still very knowledgeable on the LED bulbs front though if you meant just to tap his knowledge.
