Clicking noise coming from drain pump(no blockag)

Fwx221as1 Frigidage washer:

 

So my mothers washer is making a clicking sound when draining. It's not draining completely, but will drain with additional drain cycles. She also reported a burning smell, but I haven't replicated this. I took it apart, and there was no blockage, and the pump made the noise when it wasn't attached to any hoses and the housing off. I used a multimeter to confirm correct voltage(I'm bad with electric stuff so potentially did that wrong); I checked the pump electrical connection and the wire connected to the washer. I am assuming the pump is failing and will fail completely eventually. Should I order a replacement now, or no? Any other potential causes?

Pump noises are usually caused by small obstructions inside but if the noise was present when run separately and you can't see anything inside it then it seems like it's faulty. If the pump is very noisy and not draining well it should be replaced asap otherwise when it fails you will be left with washing machine full of laundry and water.
