The ACARS may or may not be accurate.
But, bear in mind, the 1st class galley is on the right, just aft of the cockpit bulkhead. High wattage circuits run to it from below, and wire bundles for it and other circuits run under the floor, up the bulkhead and up the outer fuselage wall.
Both the lavs and especially the galleys are very high maintenance areas, subject to heavy use and wear.
