Beretta Condensate Leak / Internal Water Leak

Water leaking from the bottom of the furnace cabinet

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Blocked condensate trap or hose, Cracked condensate collector, Loose hose connections, Corroded secondary heat exchanger (condensing models)

Safety: Turn off power. Condensate is mildly acidic; wear gloves.

Locate leak source: Remove the front panel and observe where water is originating—condensate trap, hoses, or heat exchanger area.
Clean trap and hoses: As described for A18, remove and flush the condensate trap and hoses. Reconnect securely.
Check external drain: Ensure the drain line to the building's waste system is not blocked.

If water appears to come from the heat exchanger body, shut down the furnace and call a technician immediately.
