Duet Sport Elec Dryer (not a steam model) produces about 1oz.(measured) of water in the vent hose for every hour of run time. Previous repairs done, troubleshooting for Error Code F-02, tested everything out to the point of needing to replace the Console Control Panel, did so, which fixed the display and selection of cycles issues. Runs normally except for water in vent hose bend. Cleaned vent, from dryer exhaust to roof top vent, still collects water in vent hose. Followed Tech sheet diagnostics on pg.7 for Test #3a Exhaust Thermistor, (exhaust temps check out ok). Did Test#4 on pg. 8, Moisture Sensor, checked out ok. I've upped the drying mode(Test #4a, pg.9) in hopes of drying more efficiently (unit has always been overly optimistic regarding est. dry times), but still have the water in the vent hose issue. One note: whenever entering the diagnostic test mode, the Error Code F-02 still appears and won't let me make any changes until I press the +/- buttons a few times to display the normal 88 code, then everything else works as advertised. Any ideas on how to fix the water accumulation issue would be appreciated.

Nope, the washer is the matching duet sport and does a pretty good job of spinning out moisture.

Thanks for the tip, will give your suggestion a try. Any other ideas would be welcome.

I do not think it is a moisture sensor problem. Since you are getting liquid water out of the unit I would expect the dry times to be longer.

Did you try more than one load?
My thoughts here is that there may have been water pooled in the dryer from previous loads and it spit out when you did the disconnected test.

I cannot think of any additional tests.
You have checked the units temperatures and air flow and both are OK.
You have also said that the clothes are not wet when put in the dryer.
I am stumped!!

[COLOR="Blue"]I'm not even sure which parts to throw?[/COLOR]
Everything checks out OK so I do not know.
The F-02 is a electronic communication problem but the cycles run OK other than being too long so it does not seem to effect the units operation.

In my opinion the clothes must be too wet and the unit is spinning out the water. Perhaps try a load of wash that was washed in a different washing machine.

Only other thing I can think of is that the vent pipe where the unit is located is so cold that the moisture in the warm air is condensing out as soon as it leaves the drum but you have not mentioned this so it is a long shot.

Since I am stumped I am going to ask for help from other techs on the forum in the Tech Talk section.
Hopefully someone else has seen this and will help.

Thanks for both the replies. I'm not convinced the problem is in the vent piping as I did the disconnected test that Denman suggested with the same results, about one oz. of water in the alum flex hose. I'm (fairly) confident that the clothes taken from the matching washer are not overly moisture laden and even lighter loads (t shirts and such, not heavy towels) still cause the moisture in the flex hose. Grasping at straws here.......
