i've got the same problem, still fixing it, but there is some progress. there is a coin collector at the bottom of the machine. it's hidden behind plastic cover, which is easily pops out. try to clean it up. stuff in there stops the draining motor. also i found some coins in the pressure chamber(that what i think it is) if you look at the back of the machine, there is sort of box where large hose from the drum comes into. disconnect it(it has spring fixture on it) and wonder around inside. i found almost two buck in there. hope it helps.
