Dishwasher Repair Checklist

Before calling a dishwasher technician, it’s helpful to perform some basic troubleshooting to either resolve the issue yourself or provide useful information to the technician. Here’s a checklist of things to check:

• Power Supply
  • Check the Power: Ensure the dishwasher is plugged in and the power outlet is working. Test the outlet with another device if necessary.
  • Inspect the Power Cord: Look for any visible damage to the power cord or plug.
• Water Supply
  • Verify Water Supply: Make sure the water supply valve is turned on and that water is flowing to the dishwasher.
  • Check the Inlet Hose: Inspect the water inlet hose for kinks, leaks, or blockages. Ensure it’s securely connected.
• Drainage
  • Inspect the Drain Hose: Check for kinks, blockages, or clogs in the drain hose. Ensure it’s properly positioned and not submerged in water.
  • Check the Drain Pump: If the dishwasher isn’t draining properly or is making unusual noises, the drain pump might be clogged or faulty.
• Filters and Spray Arms
  • Clean the Filters: Remove and clean the filters at the bottom of the dishwasher. A clogged filter can affect performance.
  • Check the Spray Arms: Ensure the spray arms are not blocked by debris. They should be able to spin freely.
• Door and Seal
  • Inspect the Door Seal: Make sure the door seal is clean and free of damage. A damaged seal can cause leaks.
  • Check the Door Closure: Ensure the door closes properly and latches securely.
• Detergent and Rinse Aid
  • Check Detergent: Make sure you’re using the correct type and amount of dishwasher detergent. Using too much or the wrong type can cause issues.
  • Refill Rinse Aid: If your dishwasher uses rinse aid, check and refill it if necessary.
• Error Codes
  • Look for Error Codes: If your dishwasher has a digital display, note any error codes or messages. Refer to the user manual for their meanings.
• Cycle Issues
  • Test Different Cycles: Run different wash cycles to see if the issue persists across all settings.
• Noise and Performance
  • Listen for Unusual Sounds: Note any unusual noises during the cycle, as they can help diagnose the issue.
  • Check Performance: Observe the cleaning performance to identify if there are specific issues with washing or drying.
• Manual and Warranty
  • Review the Manual: Consult the user manual for troubleshooting tips specific to your model.
  • Check Warranty: If your dishwasher is still under warranty, review the warranty terms to see if repairs are covered.

By performing these checks, you can either resolve the issue yourself or provide the technician with detailed information, which can help expedite the repair process.
