Bosch wfd2473 washing machine wont drain or spin

The machine goes through the wash program but wont drain or spin.

Filter blocked, bottom hose blocked the machine wont spin if theres still water left in the drum .

I have a bosch wfd 2473 washing machine...wont drain,I have had this problem before and resolved it by removing drain/filter plug...normally a button or hair clip....but this time there are no objects blocking.I am guessing the drain pump is faulty and needs replacing...?????
