Indesit is70c no water coming out to tray

About a year ago I had this problem and just had to clear fluff from the hole between the reservoir tray and inside so it got out to the pump.

I have done this again, but nothing happening.

The back metal cover is hot. I cleaned the condenser thing.

Air is blowing onto it, seems hot on one side, cold on other (the air).

There does appear to be a kind of knocking sound as it turns.

Can't get water out of clothes etc. Some drips out front.

Help! :)
Thanks
