Robot stop climbing walls Premier from 2014
Premier from 2014 does not climb walls, unless pushed manually. Tried everything imaginable, no success (cleaned pool walls, replaced climbing rings and brushes, cleaned filter and impeller, reset). It still works in the floor, not sure what can be done. This is an expensive machine, cannot imagine that I need to put it in garbage?
Would new power box be helpful? I would hate to waste additional $200 just to try it.
Any idea would be very helpful, thank you in advance!
