Duet dispenser leak

Small leakage from rear of dispenser assembly. If standing in back of dryer looking forward it would be to the right rear portion of assembly. There is a clip there that attaches the top cover of assembly to the bottom of assembly. It seems to be leaking from that immediate area. Nothing looks cracked or out of kilter. I have checked the hose to the tank, it is clear and the plastic shoot to the tank is clear. Help please
