Technika Dishwasher - No issues but Detergent Container Lid Broken

Works perfectly fine, is clean and in running condition. The only issue is that the LID of the Detergent container got broken, see photos. The Detergent Container can be replaced but I don't know how to do that. Tried to get some quotes online but in the meantime wife bought a new one. Hence selling, L x W x H details are in the pictures Only used for 4 and a half years. *** Pick up from Point Cook, VIC ***
