My GWL11 alternates between filling and draining so that it never fills completely. After many cycles of filling and draining, it ultimately displays error code #10. I have already replaced the pump and the motor controller. Help!
How did you decide that it is error code 10? That error code refers to the temperature sensor fault which would not make it fill and drain. Why did you replace the pump and the controller? Was there something wrong with them or did you just replace them for no particular reason?
