Water is leaking around the base of the furnace or from internal panels.

Safety: Turn off power. Avoid standing water near electrical components.

• Locate source: Remove panels and identify whether water is coming from the condensate trap, drain tubing, collector box, or vent connections.
• Clear drain: Disconnect the condensate trap and drain tubing. Flush with water and, if needed, a mild vinegar solution to remove slime. Reassemble ensuring proper slope.
• Inspect collector box: On Wolf condensing models, check the plastic condensate collector box for cracks or leaks at seams. Replace if damaged.
• Vent slope: Verify that horizontal vent runs slope back toward the furnace or per Wolf installation instructions to allow condensate to drain properly.
