I have just been on Dettol's website and one of the questions is "Can I use Dettol Laundry Cleanser (Sensitive) with fabric softener?" and the answer was
"Laundry Cleanser should be used instead of fabric softener; place it in the compartment normally reserved for the latter"
so, instead of fabric softener then is what they say , that's interesting because I have been adding it to the manual compartment in the autodose drawer.
I wonder how this will work in the autodose fabric softener compartment instead of fabric softener then and if it will be OK? - at least its not as thick as fabric softener is so maybe that would help the pump issues people are having ?
