Taz 6 not lifting back up after wiping


I have a Taz 6 that’s been giving me a “failed to probe” error on occasion lately. At this point it’s happening almost every time. The nozzle will go to wipe itself off, stay at the height of wiping, run straight to the back corner washer, and roll over the edge of the scotch pad and bump over the probe button. Any ideas why this is happening?
