I have a GE PDWT380V00SS that is 13 months old. It just started to make a noise (see youtube: ) last night. At first thought it sounded like an impeller hitting something. I rebooted the disk washer (unplug it for 30 seconds) and the noise is still there. I also noted that the tub is not filling with water. Any ideas? The only manual I have is the standard user manual which is useless.
