geospring hybrid water heater rusty condensate discharge

The GeoSpring Hybrid operating in the Hybrid mode appears to function fine with no errors but since the initial installation, the condensate discharge line (small plastic line) has always been a rusty color. I would assume the condensate being removed from the ambient air should be clear as it extracts heat from the air and transfers it to the tank. Got no answer from GE except they don't cover rust. Said I should contact a plumber.

Could be some steel component in the heat pump is rusting where the water contacts it. Could be dust in the air is promoting algal or bacterial growth, which can be almost any color. Could be a metal fitting or tubing section in the drain line rusting/corroding.

You would have to have a plumber who is familiar with hybrid water heaters dig into the condensate components and see. Certainly, you should see how to turn the power off and disconnect the line (might need to get him to put an easy disconnect fitting in the system) so in the future you can remove the line (put rag under connection so drips do not get into electrical) and wash it with vinegar and baking soda periodically to prevent blockage.
