I think the Professor is right, slates.

Fit what is known as a "water hammer arrester" also known as a "shock arrester". Around 15 to £20. Fit as near to the offending washing machine as possible.

I know it's on your neighbour's side, but it seems that you share an incoming water supply. This shouldn't happen if you are on separate meters though.
