Dishwasher not starting cycle after filling with water

Hey guys so I am a bit stuck at the moment. I have a LFT-04 Hotpoint dishwasher which stops its cycle after filling with water (looks to be the correct amount). After fillling up, I get LED 1 + 3 flashing which according to the hotpoint website indicates a faulty pressure switch or water in air trap. I replaced the switch and there is no air gap.

Circulation pump was buzzing so I replaced that. It was clogged full of jelly like mouldy food.

This also did not fix the issue. I do not believe the pump is making any noise now it's just stopping the cycle after filling. It's probable it's not even switching on after filling. I do believe I installed the pump correctly, although had to struggle a bit to fit it on the sump? bit it attaches to.

Filters have been cleaned, sprayer arm has been cleaned.

The bottom was full of old food which I removed although there is food clogging in the wash cycle pump part as shown in this manual: https://www.manualslib.com/manual/70570/...

Google results only show a recirculation pump so I am assuming this is the same part or is this some protection for the pump? It also says NEVER remove it so I am unsure how to get the clogged food out. Should I just take it out anyway?

Any other ideas?

Thanks Everyone!
