2007 315 leak

Hi I’ve had a 315 for a couple of years but recently have found a leak which I traced to a faulty pump and accumulator, which I have now replaced and all seems to be working. I think the previous leak had been ongoing for quite a while. I found water in the bilge where the bilge pump is located under the companionway, which I removed. A few days later a little more had come back. When I lifted the panel under the companionway , I could see a little water was coming from the hole to the adjoining under floor section, which is adjacent to the galley. I can’t seem to lift this panel as it’s under the galley. Is there anyway if accessing this as I’m sure that is where the residual water is sitting. I’ve checked under the saloon panels and they are all dry. Any advice appreciated.
