Possible Causes

Cracked sump, Loose hose clamp, Split circulation hose, Leaking drain hose connection

Safety first: Unplug the appliance and close the water tap.

Pull out and inspect: Pull the dishwasher out of the cabinet and inspect the underside and sides for signs of water trails.
Run a test: With panels removed, run a short cycle and observe where water drips from.
Tighten or replace: Tighten any loose hose clamps and replace cracked hoses or the sump assembly as needed.
Dry base: Dry the base tray completely before reassembling to avoid triggering the anti-flood system.
