Old Pegler tap - needs new washer, but top is stuck on

[Peterpiano]

Hi,
I have an old Pegler cold tap. The top has four prongs and a small plastic circle in the middle, but there's no grub screw to unscrew. Will there be a screw under the plastic circle? It seems difficult to remove (bloody impossible, actually) without completely wrecking it.
Or should the top just pull/twist off with a bit of persuasion?
Any help would be much appreciated.

Remove the plastic cap, Then you'll see the screw.

I have similar pegler taps, if the water is off you can sometime unscrew the shroud cover and lift it enough to be able to get your spanner on the main brass body to unscrew it & access washer! It save having to remove the tap handle head.

Sometimes I find it easier to just fit tap revivers these days! There relatively cheap, plus you get a nice new brass body & new tap heads! Sometimes putting a replacement washer in it does not last as long!

A picture of your tap would be helpful too if you still struggle

Thanks for you help so far.
Here's a couple of pics. Maybe I'm a bit of a whip, but are you sure there will be a screw under the red plastic button? I don't want to completely mess it up by removing it.
As I said before, there's no grub screw on the shaft, so maybe I have to bite the bullet and try to get the button off, exposing a screw.

definitely a screw under the red cap

There is no need to remove the cross head.
Turn your water off
Open the tap fully.
Lift the shroud up (it may be a threaded shroud depending on the age of them so you may need to unscrew it) This will reveal the nut.
Use a spanner or pair of grips to unscrew the head , swap the washer and refit in reverse order.

Either that or phone a plumber.

No they won't.
Decent adjustable, any decent set of pump pliers or proper spanner
