Bosch washer dispenser drawer tablet mush

[BazzaS]

I've a Bosch Classixx washing machine. I use washing tablets. Of late, after a wash there's the mushy remains of the tablet still in the dispenser drawer. The fabric conditioner clears out of its section of the drawer OK.
I've cleaned (toothbrush/wire) the holes above the drawer and run a 90 cycle but the problem returns.
Help please what else should I do.

Thanks

put the tablet in the net bag and put it through the door into the tub with the clothes.
