Why does the washer keep leaking on the inside after you finish with the cycle ad the load?

It could be a couple of things. The water level switch could be bad or the water supply solenoid is not closing, possibly from dirtn or debris in the solenoid or the timer is bad.

You most likely have a scaled up water valve. You can disassemble the assembly and soak the parts, except the solenoids, in vinegar or Lime-Away. Look carefully at the brass pieces on the diaphragm that have a little hole in them and make sure to clean them out. Clean the screens, too. Inspect the piece that goes in the solenoid with a spring on one end and a rubber tip. If the tip has grooves on it then you may want to replace the entire assembly so that you will have one that seals.
