Dishwasher Leaving White Residue & Water Badly Smeared

White streaks and uncleaned food particles on glass plates usually stem from clogged spray arm nozzles or depleted rinse aid dispensers.

1. Unclog Spray Arm Jets

Remove the upper and lower plastic arms and clean nozzle holes using a toothpick.

๐Ÿ’ก Master Engineer Safety Tip

Never attempt to bypass safety door switches, pressure sensors, or work on live electrical components without isolating the main power supply. If an error code persists after basic filter cleaning, call a certified technician immediately to prevent damaging the main PCB control board.
