shower blockage

[mcdommo]

Hi all
I wondered if anyone could help. I fitted a new shower and tray and waste about 3 months ago but it sometimes blocks.

Last week it was ok but the week before it blocked twice.

Sadly i tiled all around the shower tray so it is a pain to get access under the shower just to let you know.

Anyone have ideas or clues, many thanks

with most shower plug holes/wastes you can remove the grate and even sometimes the insides of the traps from the top.
