To reset the dishwasher, press and hold the "Start/Stop" button for 3 seconds until the display shows "End" or the indicator lights turn off. Then, power off the machine and restart it.
Check for clogs in the drain hose, filter, or garbage disposal connection. Ensure that the sink's drain is not clogged and that the dishwasher's filter is clean.
Remove the lower rack and unscrew the filter located at the bottom of the dishwasher. Rinse it under running water to remove debris and reassemble it back into its position.
Ensure that dishes are loaded correctly and not touching each other. Check for any foreign objects in the spray arms or filter area that could cause noise.
Ensure the door is fully closed and latched. Check the power supply, and verify that the circuit breaker has not tripped. Also, make sure the control panel is not locked.
It is recommended to clean the spray arms every 2-3 months to ensure optimal performance. Remove them and rinse under water, using a brush to clear any blockages.
Ensure that the rinse aid dispenser is full, as it helps with drying. Also, check that you have selected a drying option in the wash cycle settings.
Regularly clean the filter, use dishwasher cleaner once a month, and occasionally run a hot wash cycle with vinegar or baking soda to eliminate odors.
Regularly clean the filter and spray arms, check for and remove any lime scale, ensure the door seal is clean, and inspect hoses for leaks.
If the dishwasher isn't filling with water or fills too slowly, check the water inlet valve for blockages or damage. You may need to replace it if it's defective.
