Sime Condensate Management / Flue Drainage Issue

Water heater’s flue terminal shows signs of condensation staining or water dripping externally.

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

Incorrect flue slope, Blocked condensate trap, Cracked condensate hose, Excessive flue length causing condensation

Safety: Turn off power before working on condensate components.

Steps:

Check flue slope: Ensure the flue is installed with the correct fall back to the heater as per Sime instructions.
Inspect condensate trap and hose: Clean the trap and ensure the hose is not blocked or kinked.
Check external drain: Make sure the condensate discharge pipe is not frozen or blocked.

Professional help: Flue reconfiguration or replacement should be done by a qualified installer.
