Possible Causes

Safety first: Turn off water supply valves when diagnosing leaks.

Observe with valves closed: Turn off both hot and cold faucets. If water no longer accumulates, the inlet valve is likely seeping.
Replace inlet valve: Install a new Costway-compatible water inlet valve assembly.
Check drain hose height: Ensure proper installation to prevent backflow from the drain system.
