My dryer (purchased summer of 2019) is doing the following:
  • When I push the start button, after 30 seconds, the countdown changes from the original time to 0:600 (six minutes). (For example, on the Cotton Extra Dry cycle, the time for the cycle starts at 2 hours and 20 minutes - that's the program. It switches to 6 minutes at the 30-second point.)
  • When the now new 6-minute time displays, I can hear the pump start to run. Of course, there is no water in the sump yet because the cycle has only been running for 30 seconds.
  • At 5 minutes, the machine shuts off and gives the DR error with 1 minute left on the display. DR indicates that there is a fault with draining/pumping out the water. (But there was no water to drain)
Observations:
  • I did go in and clean the sump just to make sure there was no clog - there is not. If I fill the sump with water, the pump will remove it just fine
  • dryer does not appear to be getting hot - perhaps because it is when machine thinks the cycle is ending?
  • this happens on all cycles, even those with manual time sets (timed dry) which don't rely on the moisture sensor
  • it even happens on the Air Fluff/No Heat cycle - very weird
  • Once the time has changed from the original setting, the start/pause button will not allow me to pause/stop the cycle

The repair guy can't come for several weeks. Is there anything I might be able to reset (or even better yet fix) to get my dryer up and running again? I don't want to keep using it now because it isn't going to dry the clothes and I figure the thing with the pump is going to damage it (if that isn't already a part of the problem). I don't know if there is a way I can run some type of diagnostic program? Thanks for any help you can provide. Laura
 
Hi Laura,

I'm not familiar with this model and I couldn't locate the tech. data sheet on it. Hopefully another tech. that works on these Bosch Dryers "day in and day out" can shed some light on this problem for you.

Just noticed I made a typo in my description of the problem. In the last bullet describing what the dryer is doing, it says: It should say
  • At 5 minutes, the machine shuts off and gives the DR error with 1 minute left on the display. DR indicates that there is a fault with draining/pumping out the water. (But there was no water to drain)
It should say:
  • AFTER 5 minutes, the machine shuts off and gives the DR error with 1 minute left on the display. DR indicates that there is a fault with draining/pumping out the water. (But there was no water to drain)
 
I guess I've stumped everyone. Rats. The good news, is that there was a cancellation and the repair guy will come next week. I'll let you all know what happens in case someone else experiences the same problem. Fingers crossed that it doesn't involve ordering a part that will be stuck in port for months. Laura
 
Got it! Thanks Laura!

Repair man came this morning. He is going to replace the pump (thinks it is not operating properly, thus the DR signal) and possibly a sensor. No ETA on when the parts will arrive - hopefully soon. I'll let you know if this actually fixes the problem. In the meantime, I'm off to get a clothesline to hang up in the sunporch. Laura
 
Ok thanks Laura for the update so far.:)

Let us know what happens when the tech comes back when the parts arrive.

The repairman came back and installed a new pump and a sensor (don't know which one - believe it is a load sensor). It works now! Laura
 
Thanks Laura, on the receipt he/she gave you should be the part numbers he/she installed, can you post them here please?

Thanks!

Glad to hear its fixed.(y)
