The washer was replacement for an older TROMM LG. It fits on the old pedistal which has the screw+adhesive side plates, but a new set of side plates and screws is required. The current pedistal design has screw attachements that do not require the side plates. One potential improvement: It would be helpful to have a volume adjustment on the tone which signals the end of the cycle. The wireless notification is only useful if the phone is not on silent..., which ours is much of the time.
