Samsung dishwasher major issues

Samsung Dishwasher Overfilling or Underfilling

When you encounter a Samsung dishwasher that’s either overfilling or underfilling, it’s essential to understand the potential causes and consider some DIY solutions. Overfilling can lead to leaks and a malfunctioning dishwasher, while underfilling may result in inadequate cleaning. These issues can occur due to problems with the water inlet valve, the float switch, or clogged water supply lines.


Here are some steps you can take to address these problems:

  1. Check the Float Switch: The float switch is responsible for regulating the water level in the dishwasher. Ensure it moves freely and isn’t obstructed by debris.
  2. Inspect Water Supply: Make sure the water supply line to the dishwasher is not kinked or blocked. It should have sufficient water pressure and a steady flow.
  3. Clean the Inlet Valve: Sediment buildup can clog the water inlet valve, affecting water flow. Disconnect the dishwasher, locate the inlet valve, and clean it if necessary.
  4. Check for Blockages: Inspect the dishwasher’s drain and fill hoses for any blockages or obstructions that may hinder water flow.
  5. Adjust Water Temperature: Ensure the hot water supply to the dishwasher is set to the recommended temperature range (typically between 48 and 65 degrees Celsius or 120-150 degrees Fahrenheit).
  6. Run Hot Water First: To guarantee hot water is readily available, run your kitchen faucet with hot water for a few minutes before starting the dishwasher.
  7. Restart the Dishwasher: After performing these checks and adjustments, restart the dishwasher and monitor if the issue persists.


If the problem continues despite these DIY efforts or if you’re unsure about the cause, it’s advisable to contact a technician or professional appliance repair service for a thorough diagnosis and necessary repairs to ensure your Samsung dishwasher operates optimally.
