Philips Respironics DreamStation Troubleshooting Manual

Nothing happens when you apply power to the humidifier.

High Leak

Remove the water tank from the humidifier base, and then place the tank back in the humidifier, making sure it is completely seated.

If high leak persists, issue may be caused by a misaligned or damaged seal. Ensure that dry box seal and humidifier lid seal are in present, in their proper orientation and fully seated. If a seal has come loose, gently press around the edges of the seal to re-seat it.

The humidifier is cracked or damaged.

The therapy device is operating but the humidifier's airflow is low or stopped.

Excessive condensation in the tubing.

Heated tube is not warming.

The humidifier has fallen off your table or night stand.

Always make sure your humidifier is placed on a hard, flat surface so the rubber feet on the bottom of the humidifier base can adhere to the surface (make sure there is no fabric under the base). The humidifier must be level for proper operation.

Also, place the humidifier away from the edge of the night stand or table, so it doesn't accidentally get knocked off the table.

If the humidifier falls and water gets into the therapy device, drain all water out of the therapy device. Allow it to air dry to make sure it is completely dry before reapplying power.

If the placement of the tubing causes the humidifier to fall, make sure that you use proper hose management when setting up your device. Route the tubing behind the bed's headboard.

If the humidifier does not operate correctly after falling, contact your home care provider or Philips Respironics.

I'm having difficulty adjusting the heated humidifier setting or the heated tube temperature setting.

The water in the water chamber runs out before morning.

Under most conditions, a full water chamber should last for a typical sleep session. However, many factors impact water consumption, including: the ambient temperature and humidity in your bedroom, your humidifier or heated tube settings, the level of mask leak, and the duration of your sleep session.

First, make sure that the water chamber is filled to the maximum fill line at the start of your sleep session. Check that your mask is fitted properly, and adjust as needed to reduce mask leak to normal levels. You may use the Check Mask Fit function to evaluate your mask fit. Also, confirm that the device, humidifier, humidifier seals and tube are connected properly and not leaking. You may also choose to lower your humidifier and/or heated tube settings or change the humidification mode from Fixed to Adaptive humidification mode to increase the time that your humidifier water will last.

I hear a leak or whistling sound coming from my therapy device or humidifier (not related to mask leak).

I accidentally spilled water into my humidifier basin.

A small amount of water spilled in the basin of the humidifier will not harm your device. A small spill in the humidifier will evaporate under normal humidifier use. However, too much water in the humidifier basin could spill over the humidifier lid hinge and might damage your furniture.

Disconnect power from the device. Remove the water chamber, pour out any excess water until the water level is at or below the maximum fill line and set the chamber aside. Separate the humidifier from the therapy device, and pour out the spilled water. Once the heater plate has cooled, wipe the inside of the humidifier with a paper towel or soft cloth. If needed, dry the underside of the humidifier and confirm that your table top is dry. Reconnect the humidifier and power supply, and reinstall the water chamber.
