Most machines will allow you to remove the side and front panels so it's all a lot easier to get at or, as Fbody says, go in from the bottom (ooh err)
Knowing what type of machine it is would help? and if you live in an area where appliance repairmen can get away with charging £90 for a call out then you must be rolling in money anyway
its about £30-40 around MK
Getting it back in is a POP; put a bit of washing up liquid on the floor in line with the legs and just slide that sucker straight in remembering to arrange the hoses so they don't snag/twist etc
