It's very likely the check valve under the tank. Those can be "fun" to replace, but if it looks like you have to take them all off, there's a shortcut. Cut the fitting off right before it and add a union. I worked on one that didn't even have ball valves on it, and I thought I was going to have to shut the whole wash off for most of a day, but after the owner cried about lost income I managed to only have it down for about fifteen minutes while I cut out the bad check valve and added a ball valve so I could work on it. At least it was 170° degrees in the room because his 2 million BTU boiler wasn't vented to the outside.
It could also be one of the tubing lines that go into the manifold under the tank, or a bad fitting at one of the soap, wax, or presoak solenoids.
