Can't open pump filter on Beko WM5120?

Hi, I am registered blind and a single mother. As I have a tiny bit of vision (5%), I usually manage to do things myself. Our washing machine stopped draining so I went to empty the filter and check for foreign objects, but it turns about one quarter and then sticks, although you can easily turn it clockwise back to starting position. I tried pushing it further and part of the 'handle' broke off. It also will not lever out. I have taken the plastic front off all along the bottom of the machine. I really need help as although I work full time we have no money right now and I don't know what to do, please can anyone help??
