Removing intergrated Candy washing machine filter

[TomoTheBlue]

I have an intergrated Candy washing machine that is displaying the E20 error code. I have tried to remove the filter from the front (bottom) of the machine. The white screw cap comes off but there is some other plastic thing behind the cap that I assume also needs to be unscrewed to get to the filter. There are slots in this other thing and I have put different tools into it to attempt to unscrew it, but it just won’t budge. Any advice would be greatly appreciated. Colin.

Some filters just unscrew a bit and then pulling it pulls it all out. Such filters leave half inside if you totally unscrew it. 
 

If it isn’t like that I can’t suggest anything except to check the instruction manual. Pump filters normally just turn to the left and pull or unscrew and pull.
