David,
Your dispenser will likely be gunged up. If you take out your dispenser drawer and look at the roof of the dispenser I bet it's all black?
This means that when machine is filling water is being squirted into the wrong compartment syphoning away the conditioner. Try giving it a good clean with a nail brush.
I this doesnt help report back.
