I have a leaking AEG Lavamat 610 washing machine. I took the back cover

off and I can see the leak is coming from the water pump. I can order a

replacement pump. How easy is it to change it? And, can you get access
to the pump (to unbolt if) from the back? or do you have to remove the
front cover. I assume I can reuse the motor - as the pump works (but
leaks). Any suggestion of where to buy a replacement pump? Thank you.
