Water leak detected; machine may stop and display E13, sometimes with water in base tray.

Safety first: Unplug the appliance and turn off the water supply immediately. Mop up any visible water to prevent slipping.

Step-by-step checks:

• Inspect base tray: Remove the lower front or rear panel to check for water in the base. Many Proline combos use a float switch in the base tray; dry the tray completely and reset the float.
• Check hoses: Examine the drain hose, tub-to-pump hose, and recirculation hoses for splits, cracks, or loose clamps. Tighten or replace as needed.
• Door seal: Inspect the door gasket for tears, holes, or deformation. Replace the seal if damaged.
• Pump and tub: Look for drips around the pump housing and tub seams during a test fill (with panels off but all electrical parts protected from splashes). Replace any leaking component.

When to call a technician: If the leak source is not obvious or involves the main tub, professional diagnosis and repair are recommended.
