Re: HDM Z1 Have a fault 33 code. Anyone know how to fix it?
Z1 cpap about 6-7 years old (lightly used) with new error 33. I tried replacing the pressure sensor with a new MPXV5004GC6U as mentioned in other posts. The new sensor soldered in and fit fine. Unfortunately no luck as error 33 continued to appear.
