X11 right function indicator lite green but left function lite and battery lites not illuminated

My X11 Pool Cleaner was working fine. Plugged it in to recharge. Charger indicator turned green. After unplugging from charger, I put the cleaner in S mode and only the right function indicator lighted up green. The left function indicator and the battery status indicators do not light up and the cleaner will not work. Same for the F mode. Both the left and right tracks can be moved manually.
The charger indicator is green when not plugged into the cleaner.
Any assistance would be appreciated.
