Do you have a one way vent under the kitchen sink? If it’s stuck closed the drain isn’t vented and might not drain properly. The same would be true if the sink vents through the roof if that is blocked by something. Draining the tanks might create enough of a vacuum to pull the water through. Easy to check.
