easy fix.
lift out the blue part of the conditioner compartment and you'll see attached a tube at the end.
clean this out completely.
also check the tube in the compartment is clear.
poke a cotton bud down it to clear it.
if you want to check to see if its worked take the drawer out(blue button at back of drawer) put the blue grid back in the dispenser and fill the compartment up under the tap ,hold the drawer level.
as it gets full you should see water start to flow out the back ,turn the tap off and if its worked the compartment will slowly empty.
these were a big problem for hotpoint and concentrated conditioners will block it regularly.
