Bosch WTW87NH1UC dr Error Code | dr Door Not Closed

Error dr on Bosch wtw87nh1uc: Door not closed — door is open or door switch is not detecting door in closed po. Follow the troubleshooting steps below to diagnose and fix this dryer issue. ## What Does dr Mean on a Bosch WTW87NH1UC? Your Bosch dryer is displaying a ‘dr’ (door) error code, which means the dryer cannot detect that the door is properly closed. The dryer requires the door to be securely latched before starting or continuing a drying cycle — this prevents hot air from escaping and clothes from tumbling out. The ‘dr’ code appears when the door is physically open, when the door latch is not fully engaged, when clothing is caught in the door, or when the door switch has failed and is not registering a closed position. ## Fault Details | Field | Value | |-------|-------| | Error Code | dr | | Appliance | Bosch WTW87NH1UC 500 Series 24-inch Compact Ventless Heat Pump Dryer | | Fault Type | Door not closed | | Severity | Low | | User Serviceable | Yes — follow steps below | | Applicable Models | WTW87NH1UC, WQB245AXUC, WQB245B0UC | ## Common Causes - Door is physically open or not fully pushed to the closed and latched position

  • Clothing item caught between the door glass and the drum opening, preventing full closure
  • Door hinge damaged or misaligned, preventing the door from reaching the latch position
  • Door latch (striker) worn or broken — door closes but does not click into locked position
  • Door switch (micro-switch) failed — switch not activating when the door is closed
  • Door gasket protruding and blocking full door closure ## Step-by-Step Troubleshooting | Step | Action | What To Do | Expected Result | |------|--------|------------|-----------------| | 1 | Check for clothing caught in the door | Open the door and inspect the door gasket perimeter for any items — socks, small garments, or fabric pieces trapped between the gasket and the drum. Remove all obstructions and firmly push the door closed until it clicks | Door closes with an audible click; ‘dr’ code clears | | 2 | Test door closure with the cycle running | Start a new drying cycle and observe the display. If ‘dr’ clears immediately when the door is firmly closed and the cycle starts, the door was simply not fully latched. If ‘dr’ appears again after the door clicks shut, the door switch or latch may be faulty | Cycle starts normally after firm door closure — latching issue resolved | | 3 | Inspect the door gasket for bulging | Run a finger around the door gasket. If any section has separated from the cabinet frame or is protruding inward, it may prevent the door from closing fully. Firmly press the gasket back into its channel | Gasket fully seated around door perimeter — door closes completely | | 4 | Check door hinge and latch condition | Inspect the door hinges for bending or looseness. Check the door latch receptacle on the cabinet for damage. A worn latch striker or a bent door may not allow the latch to engage | Door hinges and latch intact — no deformation visible | | 5 | Contact Bosch service for door switch replacement | If the door closes, clicks, and appears fully latched but ‘dr’ persists, the door switch micro-switch has likely failed. This requires accessing the door interior. Contact Bosch at 1-800-944-2904 for professional door switch replacement | ‘dr’ resolved after door switch replacement | ## Frequently Asked Questions ### Can ‘dr’ appear during a running cycle? Yes. If the door pops open or the door switch intermittently loses contact during a cycle, ‘dr’ will appear and the dryer will pause for safety. This is more common on older units with worn door hinges or latches. Persistent mid-cycle ‘dr’ codes indicate a failing door switch or weakened door spring. ### How do I know if my Bosch dryer door switch is faulty? If the door clicks shut, the latch appears engaged, but ‘dr’ still shows, the door switch is likely faulty. A technician can confirm by testing the switch with a multimeter — the switch should show continuity when the door is closed and open circuit when the door is open. ### Can a stretched door gasket cause ‘dr’? Yes. An old or damaged door gasket that has lost its shape can bulge inward, preventing the door from fully closing. Replace the door gasket if it is deformed, torn, or no longer seating flush against the cabinet opening. ### How long do Bosch dryer door switches last? Door switches typically last the life of the dryer (8–12+ years) under normal use. Switches can fail earlier if the door is frequently slammed or if the machine vibrates excessively due to an unlevel installation. Gentle door handling helps extend switch life. --- Source: Bosch 500 Series 24-inch Compact Ventless Heat Pump Dryer service documentation.
