Diverter Motor Assembly
The diverter motor governs the distribution of water between the various spray arms. A failure in the internal gearing or a leak in the shaft seal typically leads to the motor seizing, which prevents the internal cam from opening the port to the upper spray arm. This results in the top rack receiving no water while the bottom rack may still function.

Circulation Pump Motor
This BLDC (Brushless DC) motor generates the hydraulic pressure required for the cleaning cycle. If the impeller is damaged or the motor bearings have increased friction, the pump cannot maintain the high-velocity flow needed to reach the top rack nozzles, causing poor cleaning results despite the arms spinning slowly.

Water Supply Tube Assembly
The supply tube delivers water from the sump to the middle and upper spray arms. If the docking gasket where the top rack meets the tube is deformed or if the tube itself has developed a stress crack, the resulting loss of pressure will prevent the spray arms from reaching the RPMs required for effective mechanical soil removal.
