remove the top cover of the machine,(power off) and disconnect the flexible hoses from the dispenser. Check if theyre blocked. The dispenser itself can be separated - generally held together with plastic clips. Clean out any crud or hardened detergent. Top generally slides off towards the rear of the machine after removal of screws at rear.
