Bosch Dryer DR Code: Door Not Closed or Condensation Water Not Draining (How to Fix It)
What the code means
Bosch's US dryer error code guide lists DR as the door not being properly closed or an issue with the door switch. It says to make sure the door is firmly closed and not obstructed, and if the code persists, to inspect the door latch and switch for visible damage or misalignment and check that the wiring connections are secure. Bosch's own manuals agree that a door that isn't latched stops the dryer: the WTG86403UC manual says that if the door has not been closed properly the dryer will not start, and to check for laundry caught in the door and close it until you hear a click. On that same 300 Series condenser dryer, though, the manual's troubleshooting table uses a DR indicator for a different problem: water has not drained completely because the drain hose is blocked. Condenser dryers collect the water pulled out of the laundry, and on models plumbed to a drain the water leaves through a drain hose. The manual says that if the DR indicator lights, check the drain hose for kinks, restrictions or blockage and check the hose connection, and if DR still lights up after that, contact Customer Service. So the fix depends on your dryer: look up the use and care manual for your exact model (the E-Nr on the rating label inside the door) to confirm which meaning applies.
Likely causes
- Door not fully closed or latched, which Bosch's US error code guide names for DR
- Laundry caught between the door and the opening, so the door can't click shut (Bosch WTG86403UC manual)
- A damaged or misaligned door latch, a failed door switch, or a loose switch wiring connection (Bosch US guide)
- On the WTG86403UC condenser dryer, a kinked, restricted or blocked drain hose that stops condensation water from draining (Bosch manual)
- On that model, a poor drain hose connection at the back of the dryer or at the drain (Bosch manual)
Safe DIY checks
Unplug the appliance or switch off its breaker before opening panels.
- Find your model number on the rating label (Bosch calls it the E-Nr). If you have the WTG86403UC or another Bosch dryer whose manual pairs DR with drainage, start with the drain hose steps; otherwise start with the door.
- Door: open it, remove any clothing or fabric caught in the opening or seal, and close it firmly until it clicks. Bosch says the dryer won't start if the door isn't closed properly.
- Door: look at the latch and hinges for visible damage or misalignment. Don't force a bent door shut.
- Drain hose (condenser models plumbed to a drain): turn the program selector to Off, then check the whole length of the drain hose for kinks, restrictions or blockages and straighten or clear it.
- Drain hose: check that the hose is securely clamped on the hose barb at the back of the dryer and that the other end is still properly in the drain. Bosch's manual says to check the drain hose connection conditions.
- Restart the program. If the power was interrupted, Bosch says the program won't resume on its own; check the settings and press Start/Pause.
๐ When to call a pro
- DR stays on with the door firmly closed and clicked shut: the door switch, latch or its wiring likely needs service. Bosch's guide points to the switch and wiring, which sit inside the cabinet, so call Bosch at 1-800-944-2904 or an authorized technician.
- On a condenser model, DR still lights after you've cleared and reconnected the drain hose: Bosch's manual says to contact Customer Service, since the internal drain pump or its circuit may be at fault.
- Water is leaking out of the dryer: Bosch's manual lists an unlevel dryer, a dirty condenser seal and a leaking drain hose. Fix those, and call service if the leak continues.
