Seaps out under the lid??? I assume you mean the door. AS you do not give full info, I assume the door on the front. IF top loader, would be a lid.
So for that probably seal gone, Replace.
As for water in m/c Always. The pump will pump out, BUT it pumps up over to the outlet pipe. AS long as outlet is clear, most of water will go out. BUT when the pump stops, ALL the water in the pipe, will go back into the m/c Water finds its own level. The pipe is already full, so the water will be in base of m/c.
