The noise filter in a Samsung dishwasher minimizes electrical interference, allowing the appliance to operate smoothly and quietly. It may be time to replace this component if you’re experiencing excessive noise, power disruptions, or electrical issues like flickering lights or tripped circuit breakers.
Signs of a Faulty Noise Filter
It’s important to identify the signs of a malfunctioning noise filter before replacing it. Here’s what to watch for:
- Excessive Noise: Buzzing or humming sounds during operation.
- Power Interruptions: Dishwasher turning off unexpectedly or failing to start.
- Electrical Issues: Flickering lights or repeated tripping of circuit breakers.
- Burn Marks or Smell: Visible damage, such as scorch marks or a burnt odor coming from the filter housing.
If you notice any of these issues, the noise filter may need replacement.
Tools and Materials Needed
- Replacement noise filter (compatible with your dishwasher model)
- Phillips screwdriver
- Flathead screwdriver
- 5/8-inch wrench
- 9/64-inch hex screwdriver
- Pliers
- Towels
Confirm Part Compatibility
To avoid installation issues, confirm that your replacement noise filter matches your dishwasher model. Locate your dishwasher’s model number, which may be found in these areas:
- Side panel or door frame
- The back or bottom of the appliance
- Control panel or console
Look for a label with “MOD” or “Model” before the number. Write it down or take a photo for reference.
Follow Safety Precautions
When working on any appliance, prioritize safety. Here’s a checklist to keep in mind:
- Unplug the dishwasher or switch off the circuit breaker to eliminate the risk of electric shock.
- If the appliance was recently used, wait for it to cool down before starting.
- Turn off the water at the outlet, and have towels ready to catch any residual water.
- Make sure the area is well-lit, free of clutter, and inaccessible to children or pets.
- Avoid working with wet hands and confirm the workspace is completely dry.
- Avoid excessive force to prevent damage to the appliance or injury.
- Insulated gloves can protect your hands from sharp parts or debris.
- Take photos or notes of wiring terminals and connections to simplify reassembly.
