Issues with Timer and /or filter (newbie)

[yeros]

Hi there,

This is my 1st post, so please be nice with me

We bought a house and there is middle size ground pool ... 4-5 days pool filter and timer was off, and when we tried to turn-on pool filter - I noticed that it doesn't stop. It's scheduled for 8 hours work (6pm - to 2am), but unfortunately timer doesn't stop and last 2 days I need to turn-on/turn off manually from the switch.

Guys, can you tell me what I'm doing wrong and how can I force timer to work.

Timer T104 (unfortunately manual is in Spanish, but I checked some youtube videos and everything seems setup right)

I Googled Timer T104 and came up with this
https://www.intermatic.com/en/Timer-Controls/Mechanical-Time-Switches/T104 (their is an instructions download link on the page)
It's a very simple electro mechanical time switch
The only thing that I assume it could be is that it's not moving or is set to manual
Try moving it round by hand and see if any thing works
