Leaking!!

I use a Respironics Comfort Lite interface with the "pillows". I have had it for about 10 months and really like it. I have a Respironics Pro machine and use humidity set at 2. I just got the CPAP machine back yesterday after it had to be repaired. The machine is just under 3 years old. Last night the interface leaked all out where it attaches to the hose and around my nares. It did not seem to affect my sleeping except that when I was up once in the night and removed it, I had rainout all over my face and I could feel water a bit around my nose when it started up again. It seemed to dry up as the machine and humidity kicked in. I did go back to sleep but this morning more rainout and my pillow was wet where the the interface connects to the hose at the top of my head. The same amount of water was left in the container as usual so no leaking there I guess. Any ideas about what might be going on? I will call my provider today but thought I would ask here first.
