**To quickly clear most error codes on your Philips Respironics DreamStation 2, perform a hard reset by unplugging the power supply from the wall outlet, waiting 30 seconds, and plugging it back in.**
If the quick reset does not resolve the issue, use these targeted steps to clear specific error codes on your device:
### How to Perform a Complete Hard Reset
If a simple unplug doesn’t work, clear the machine’s temporary memory with a deep power cycle:
* **Disconnect all power:** Unplug the power cord from the wall outlet and the back of the DreamStation 2.
* **Remove accessories:** Slide off the humidifier water tank and unplug the heated tubing.
* **Wait for discharge:** Leave the device completely disconnected for 2 full minutes to drain the internal capacitors.
* **Reassemble and power up:** Reattach the water tank, reconnect the tubing, plug the power cord back in, and press the **Therapy Button** to clear the screen.
### Clearing Specific Sensor & Connection Errors
Many DreamStation 2 errors are triggered by poor component connections. Clear them by reseating these parts:
* **To clear Humidifier/Heater plate errors:** Remove the water tank, wipe the gold electrical contacts on the bottom of the tank and inside the machine bay with a dry microfiber cloth, then slide the tank back in until it clicks firmly.
* **To clear Heated Tube errors:** Disconnect the heated tubing from the back of the machine. Inspect the connection pins for dust or damage, then firmly reattach the tube until the locking tabs click into place.
* **To clear Airflow Blockage/Filter errors:** Turn off the machine, remove the foam pollen filter and the ultra-fine filter from the back, tap out any dust (or replace them if dirty), reinstall them, and tap the screen to clear the alert.
### What to Do If the Code Will Not Clear
* **Identify locked hardware codes:** If your screen displays a persistent “Service Required” message or a code beginning with “E-” (such as E-3 or E-7), these represent internal mechanical failures.
* **Contact your DME provider:** These specific hardware error codes cannot be cleared manually by the user and require you to contact your medical equipment provider for a warranty repair or replacement.
