Thanks DOMSAT313, I found 2 20p, 2 5p and 1 10p piece in there, also one small pipe, like a breather pipe, was completely blocked by what I can only describe as clay.
It worked great after I cleaned this lot out and remembered to re-connect the power cable after I'd re-connected everything and loaded it with clothes and set it going. It started 'clicking' again and I then had to tip it on its side again to connect the power lead - great fun! but at least it works now.
