How can I fix my hotpoint BWM129 1200spin?

Our outlet hose was full of muck when I looked at the end that connects to the unbend of sink, I decided to clean it out with a small brush on a meter long flexible wire, but all I did was to ram the muck down to the filter pump, when I tried to get the machine to pump out the muck it dint have enough force to bust through the blockage.
I had a bright idea, Hmmmmm!! I connected our garden hose to the end of the pipe and blew the rubbish into the washing machine, that cleared it!! But now when I turn the drum by hand there is an awful clicking/grating sound. It did however pump all the water and muck out and spun quietly but when in a wash cycle it is grating and noises. Is there something in the drain pump that I could have blown into the machine??
