000.4 - Dreaded ductless dryer DR code remedy

- This short howto video shows how to clean and likely eliminate the DR code on a ductless dryer when caused by a fouled sump pump. While specific to the Bosch 300 Series stackable unit, much of this is likely similar on other similar dryers.
The Torx screw in the video is a T-15 and is removed when pulling the pump out of the sump.
For a great overview of these dryers, please see Matt Risinger's video at:
• The Case For Ventless ...
This video goes a bit further but does not repeat another helpful video at Rob's Garage Woodworking which you should watch first if working specifically with the Bosch 300 Series:
• How To Fully Clean Bos...
We use this dryer in our super tight house as the only penetration in the house envelope beyond open doors or windows is the Zehnder ComfoAir 200 heat recovery ventilator.
This is an early episode for @outbuildinginfo, a channel devoted to building things, tools, and new design ideas. The first 9 of these episodes are "point releases" which will help develop the channel voice, learn the tools, and develop a pattern for documenting building projects, reviewing tools, and sharing workshop enhancements along with occasional howto's.
Thanks for sharing in the learning curve.

I had no idea how to get into that sump pump chamber, or even where you were, but the video you referred us to, Rob’s Garage Woodworking, showed all the details. Saved us from an expensive appliance repair!
Thanks for commenting. I'm excited to hear you avoided the repair. These dryers work great but occasionally require this cleaning step. We have found that we do it without removing the pump about every 6 months (for our use pattern) and that tends to keep things working well.
I have the Bosch 500 series ductless. The Canadian guy who made the video does a fantastic video as well on that Bosch unit.
I clean mine at least twice a year, I’d do it more often, but it’s our second set of and doesn’t get used as much.
So thankful for these videos, most likely saving me $$ hundreds in service charges..If you can find an appliance repair.
Good repair is tough to find in the world we live in where it is often suggested you just toss the unit and purchase another. Nice that these work well and with minimal maintenance can be continuously used.
Nice lesson on keeping your appliance working properly. This should be a lesson for the Bosch design engineers. Perhaps they should ship the dryer with a torx driver and some hemostats!
So true. If I were to sit over a beer with the Bosch folks, I would suggest a simple door panel in the back that would allow access to this little sump area. The back is already a piece of molded plastic and that change would allow super easy cleaning. That might even be less expensive than shipping hemostats and a torx driver!
Wow that was the best ventless dryer video ever made thank you
Thanks for the positive feedback. It isn't a videography masterpiece by a stretch but hopefully it is helpful or those frustrated by the codes. With this small fix occasionally, we have had really good results with our dryer.
Very helpful and informative. Thank you!
Thanks for the positive feedback. Looking back at this, the video quality isn't great but hopefully the information helps. If (when) I go through this again, perhaps I'll refresh the video.
Thanks for posting this video. Saved me big time.
Thanks for watching and commenting. I'm glad to hear this helped on your end!
Thanks for this video! I found that there is a channel with enough vertical space above the plastic housing to lift it over the pump and attach it after connecting the wires and drain hose. This is much easier than popping out the drain hose fitting and connecting it from outside.
That is awesome. I need to do this again soon and will give that method a try.
@@outbuildinginfo Did you try that method? We have a situation where the Washer/Dryer stack is in a cabinet directly adjacent to a toilet. In order to get to the back of the stack we have to pull the toilet and then slide the stack out. If this method that allows for cleaning of the sump without removing the pump assembly entirely (as described above) works, it is a godsend to me. Our Series 800 stack is 4 years old and we started getting the DR error about 6 months ago. I watched the Canadian video and the cleaning as described in that video cleared the error for a while but now we are getting the error again and it is likely that the buildup in the sump reservoir area that you show is what is leading to our more recent error given that the rest of the condensing apparatus is clean. Thanks so much for the video and I hope this method works!
The bad news is that I haven't tried it. The good news is that the dryer has been working since the video without needing to be cleaned. Famous last words.. I may just clean it out this week over the holiday to avoid an unexpected downtime.@@teambumblebee01
@@outbuildinginfo Hi there, I found a couple of other videos on pulling the sump pump and cleaning the assembly and reservoir - all from the front: ua-cam.com/video/7q-2zAiBFyw/v-deo.html&t and ua-cam.com/video/f6-7IJubg0U/v-deo.html&t
They both show a step by step procedure for doing everything from the front and it works! There is no issue with pulling the drain tube from the front, pulling the pump assembly, and cleaning everything. Hope this helps; for me it was critical as I did not want to have to pull the stacked washer dryer and pull the toilet just to clean the sub pump assembly and reservoir.
Thanks for sharing! I'll take a look. Lately, I reach back there and mop it up occasionally and haven't needed to dismantle anything since. I think having had it out, I now know where to clean.@@teambumblebee01
I think I will clean out the reservoir, exchanger and everything else more frequently so I don’t have to service the pump. My series Bosh 500 set is 3 years old and have not had any failure warnings yet.
Peter, thanks for the comments and for watching. I agree on doing this at some interval. It is pretty easy to scrub out with out pulling the pump and it seems to sort of develop a sludge over time that can be readily removed. I haven't figured out the timing exactly and it probably depends on what you are washing, your environmental conditions, and how frequently.
Thanks dude!
Happy to help! Thanks for watching.
Wow thank you!

I cant open that door
If you mean the door on the "floor" of the chamber, it is a bit tricky. There are two tabs that need to be moved to release a catch on each side and while doing it, you need to lightly pry the door up. Once it is up and out, you will see how it obviously works. Getting it out the first time is challenging.
