HD11

The HD11 has 12 catalogued probe and guide references here — pick the one matching your probe label for its fault table. Philips accounts for most of what is catalogued on this system. Types catalogued: endocavity, phased-array and convex. On these, seal failure and fluid ingress is the failure mode we see described most often. Send the full probe label photo along with the console model — revision differences matter for the assessment.
