hi, I have a sears kenmore top loading, coin operated machine(model #110.82405130). The problem is that no hot water will go into the machine. The hose in the back entering the machine gets hot, but no hot water goes in. We had a plumber look at it, and he said it could be the fill valve. Do you agree, and if so where can I find a manual on the internet explaining how to replace the fill valve. thank you for your help...pete
