Issue: Dishwasher not starting or responding

Check the power supply: Ensure that the dishwasher is properly plugged in and that the circuit breaker hasn't tripped.
Test the door latch: If the door latch is faulty or misaligned, the dishwasher may not start. Inspect the latch and adjust or replace it if necessary.
Reset the control panel: Some dishwashers have a reset function that can be activated by pressing a specific button sequence. Consult your user manual for instructions.

Issue: Dishwasher not cleaning dishes properly


Check spray arms and nozzles: Remove and clean the spray arms and nozzles to ensure they're not clogged with debris. Use a toothpick or small brush to dislodge any blockages.
Clean the filter: A dirty or clogged filter can affect cleaning performance. Remove the filter and rinse it under running water to remove accumulated debris.
Use the right detergent: Ensure you're using the appropriate dishwasher detergent for your water hardness level and dishwasher model.

Issue: Dishwasher not draining water

Clear the drain filter: Locate the drain filter at the bottom of the dishwasher and remove any food particles or debris. Clean it thoroughly and place it back.
Check the drain hose: Ensure that the drain hose is not kinked or clogged. Straighten the hose and remove any obstructions.
Inspect the drain pump: A faulty drain pump can prevent proper drainage. Check for any signs of damage or blockage and replace the pump if necessary.

Issue: Dishwasher leaking water

Inspect the door gasket: Check the door gasket for any signs of wear, cracks, or damage. Replace it if needed to create a proper seal.
Tighten connections: Ensure that all hose connections are secure and tightened. Loose connections can lead to leaks.
Examine the float switch: A malfunctioning float switch can cause overfilling and leaks. Test the switch and replace it if necessary.
