Hi,
The dishwasher wont drain and the panel displays "C3" which means Drain Sensor not functioning. I replaced the pump and motor a couple of months ago after a leak and it's been working fine. I don't think the drain solenoid was part of the new pump and motor but I'm not sure on that. One question is how do I know if it's the Solenoid Sensor or the Turbidity Sensor? I removed the lower front panel and moved the solenoid sensor's arm up and down but nothing happened. The solenoid sensor is around $60, but I don't want to spend that and then have it not fix the problem. Any other possibilities. Can I check the solenoid somehow to confirm it's not working?

Thanks very much.
