How to test a dishwasher circulation (wash) pump motor

The wash motor pushes water to the spray arms. Older units use an AC induction motor; many newer ones use a brushless DC motor driven by the board. Rule out a jam and a filter clog before testing, and use the tech sheet for winding values.

How to test a wax motor (dispenser, lid lock, diverter actuators)

A wax motor is a slow thermal actuator: a small heater melts wax that pushes a plunger out over a minute or so. Test the heater resistance and watch it extend when powered.
