DreamStation PRO issue - cam - 01-12-2018

I just purchased a Philips Dreamstation PRO. I only have one question... On the first night, I noticed that there was some residual water on top of the heater plate. A few drops were also in the silicone orifice which the humidifier butts up to. I think it may be from filling the reservoir to the MAX fill level and maybe the sloshing water (as I carried it) got into the tube which provides air from the main chamber into the humidifier as well as possible back flow as a result of putting the mask on after the machine turns on. The air might be causing water to splash upward and out. Has anyone else had this problem?

It’s very easy to overfill a humidifier chamber. What I do, is fill to just under the line, instead of right on the max fill line.

I would make sure that everything is dry. Remove chamber, and use a soft cloth to dry whatever you can and let everything air dry for a bit.

Also, make sure your hose is angling downward toward the humidifier, so that any moisture would flow back in.

Thanks for the reply. I agree with you completely. Indeed it is very difficult to see the MAX FILL LINE on these units unlike others I have used in the past. Unfortunately with the furnace running more often up here in the GREAT WHITE NORTH it does tend to dry the air quicker so I was afraid to underfill  it just in case it does run dry but presently seems to be using about 1/2 of the reservoir water supply.  It certainly doesn't help that these units lack a water fill or quantity window which almost every other comparable unit seem to have.

In time, you will figure out what your humidifier usage is. Of course, that changes with the season. Don’t forget, you can always run a stand alone humidifier in your bedroom, which could be helpful.

Alot of the usage depends on the temperature and humidity level already in your room.

I used a black permanent marker to outline the full marks on my chamber.

One way I found to get the water level right without worrying about the fill line is to watch where the water level hits the bottom of the air tube in the middle of the water chamber. I found that stopping when there was between 1/2" to 1"  of water spread out across the bottom of the tube the level was good. This is much easier to see and just a accurate as using the fill marks. The image below shows the water level on the bottom of the tube when the water is right on the full mark. You could fill the chamber to the full line and look at the bottom of the tube to get a better idea of what I'm talking about.

Thanks for the photo.  That's exactly it.  I think besides carrying it from the bathroom to the bedside which may have caused some water to enter the tube, it was also a bad idea to turn the unit on before putting the mask on which probably caused a lot of spraying internally as well.

The air tube is actually sloped down toward the open end to make it harder to get water into the machine. I have actually filled the chamber enough to have water in the air tube and no water got in the machine, although it did gurgle for a while until the water level went down.

I think the most likely cause was water being sloshed into the unit when putting the chamber into the machine or when moving the machine after putting the chamber in. I always tip the back of the chamber down while placing it into the tray. Also, always remove the chamber before lifting or tipping the machine.

Thanks very much! Now I also just use the bottom of the tube to gauge the water level.
