No not usually. If it is a double drawer you need to establish which one is leaking. Just use one drawer for several washes & check after each wash for any leak. If none then use the other drawer & repeat. Once you know which one then check the lid seal is ok & the surface on the top of the drawer where the seal sits is clean. You can remove lower drawer & check for any leak around inlet hoses & valve.
