I reckon apart from Blackfell, there will be a few other places in Washington that jump out (excluding the industrial estates). Ayton for example. 

A number of places not on the Durham Road, Stockton Road or Hylton Road corridors should have to incur a couple of changes I reckon. 
Anywhere on those roads, all have a direct link to Gateshead or Durham.

Few I can think of: 
Blackfell & Oxclose - 85/86 > 56/X1 > X66
Washington Village - 84 > 56/X1 > X66
Parts of Greater Usworth - 4 > 56/X1 > X66
Mount Pleasant (controversial, but was a District!) - 4 > 56/X1 > X66

But I suppose it comes down to how far you expect to walk... e.g. the village is a village, but it'd take you 10 minutes to walk to the other end of Spout Lane for the 56. Same with Mount Pleasant and walking to Harraton Community Centre.

Blackfell is probably the most genuine example.
