If your Electrolux dishwasher isn’t cleaning dishes as it should, several factors could be to blame. The dishwasher’s cleaning process involves multiple components working together to ensure water, detergent, and heat are distributed properly to remove dirt and grime. If any of these components malfunction, the cleaning performance can be compromised.

In this detailed guide, we’ll explore the key parts to inspect when your Electrolux dishwasher isn’t cleaning properly and provide step-by-step instructions on how to troubleshoot each issue.

1. Filters: Essential for Efficient Water Flow

Dishwashers rely on filters to trap food particles, grease, and debris that come off your dishes during the wash cycle. When the filters are clogged, the dishwasher’s ability to circulate water is reduced, leading to poor cleaning results.

Why Filters Matter

• Coarse Filter: Traps large food particles and prevents them from clogging the drain.
• Fine Filter: Catches smaller food particles to improve water circulation.

How to Inspect & Clean Filters

• Turn off the power to the dishwasher by unplugging it or switching off the circuit breaker.
• Remove the bottom rack and locate the filters at the bottom of the dishwasher.
• Twist and pull the filters out. The coarse filter is typically larger, and the fine filter is underneath.
• Rinse the filters under warm running water to remove trapped debris. Use a soft brush or sponge for stubborn buildup.
• Once cleaned, reinstall the filters, ensuring they are secured properly in their slots.

Signs of a Problem

If your dishwasher leaves food particles on dishes or emits a foul smell, the filters may be clogged. Clogged filters are one of the most common reasons for poor cleaning performance, so regular cleaning is essential.

2. Spray Arms: Distributing Water Effectively

The spray arms are responsible for distributing water to clean the dishes. If the spray arms are obstructed or aren’t spinning correctly, water won’t be evenly distributed, and your dishes won’t be thoroughly cleaned.

Why Spray Arms Matter

• Water Pressure: Spray arms rely on high water pressure to spray detergent and water onto dishes effectively.
• Clogged Holes: Over time, mineral deposits or food particles can block the spray arm holes, preventing water from reaching certain areas.

How to Inspect & Clean Spray Arms

• Remove the bottom rack and lift the spray arm out.
• Check the spray arm holes for any blockages. Use a paperclip, toothpick, or small brush to clear out debris.
• Test the rotation by manually spinning the spray arm. It should rotate freely. If it doesn’t, there may be an issue with the mounting or motor.
• Run water through the spray arms to ensure proper water flow from all holes.

Signs of a Problem

If your dishes have food particles stuck to them or are not fully cleaned, the spray arms may be clogged or obstructed. If the spray arms don’t rotate or only partially spin, water won’t reach all the dishes.

3. Detergent Dispenser: Timing and Proper Dispensing

The detergent dispenser releases detergent during the wash cycle. If it doesn’t open fully or releases detergent at the wrong time, your dishes won’t get properly cleaned.

Why the Detergent Dispenser Matters

• Proper Dispensing: If the dispenser door doesn’t open fully or at the correct time, detergent won’t be released when it’s needed.
• Blockages: Old detergent residue can build up and block the dispenser, preventing it from opening correctly.

How to Inspect the Detergent Dispenser

• Open the dispenser and check if it opens fully during the cycle.
• Inspect the door for any blockages or detergent buildup. Clean any residue inside the dispenser with a damp cloth.
• Check the latch mechanism to ensure it’s working. If the latch is broken, it may not open the dispenser door.

Signs of a Problem

If detergent remains in the dispenser after the cycle or your dishes are not properly cleaned, the dispenser may not be opening at the right time. A clogged dispenser or broken latch can significantly reduce cleaning efficiency.

4. Circulation Pump / Wash Impeller: The Heart of Cleaning

The circulation pump (or wash impeller) pushes water through the spray arms and circulates it throughout the dishwasher. If the pump is weak or malfunctioning, it won’t create the necessary water pressure for effective cleaning.

Why the Circulation Pump Matters

• The pump ensures water reaches all areas of the dishwasher and provides the necessary pressure to clean dishes effectively.
• If the pump is not working at full capacity, the water pressure will drop, resulting in ineffective cleaning.

How to Inspect the Circulation Pump

• Listen for unusual sounds during the wash cycle. A malfunctioning pump may make a humming, grinding, or buzzing noise.
• Check for leaks around the bottom of the dishwasher. Water pooling may indicate a problem with the pump.
• If accessible, inspect the pump motor for any visible damage or blockages that could be obstructing the flow of water.

Signs of a Problem

Weak water pressure or inconsistent spray arm rotation is often a sign of a failing circulation pump. If the dishwasher isn’t distributing water properly, it’s likely that the circulation pump is either clogged or defective.

5. Water Inlet Valve: Ensuring Proper Water Flow

The water inlet valve controls the amount of water entering the dishwasher. If the valve is clogged or malfunctioning, the dishwasher won’t receive enough water to clean effectively.

Why the Water Inlet Valve Matters

• A clogged or stuck valve can prevent the dishwasher from filling with the correct amount of water.
• Without sufficient water, your dishwasher will not be able to generate the necessary pressure for cleaning.

How to Inspect the Water Inlet Valve

• Check the water supply to ensure the valve is open.
• Inspect the valve for clogs. You can clean the valve with a damp cloth or run water through it to check for blockages.
• Test the valve’s continuity using a multimeter. If there is no continuity, the valve may need replacement.

Signs of a Problem

If the dishwasher is not filling with enough water or the cycle is incomplete, the water inlet valve may be clogged or defective. Low water levels inside the dishwasher during a cycle are a clear sign that the inlet valve isn’t functioning correctly.

6. Heating Element: Ensuring Hot Water for Effective Detergent Activation

The heating element is responsible for raising the water temperature to around 120°F (49°C), which is optimal for detergent activation and cleaning. If the heating element is malfunctioning, the water won’t get hot enough to clean effectively.

Why the Heating Element Matters

• Hot water activates detergent, dissolves grease, and helps sanitize dishes. Without proper heat, detergent won't perform at its best, and your dishes may remain dirty.
• The heating element ensures the water is hot enough to break down grease and food particles.

How to Inspect the Heating Element

• Look for visible damage on the heating element. If there are cracks, burns, or exposed wires, it’s likely faulty.
• Use a multimeter to check for continuity. If the multimeter shows no continuity, the heating element needs to be replaced.
• Check the water temperature to ensure it reaches at least 120°F (49°C). If the water is cold, the heating element may not be functioning.

Signs of a Problem

If the water doesn’t get hot enough or if your dishes are still greasy after a cycle, the heating element may need repair or replacement.

7. Control Board: The Brain of Your Dishwasher

The control board manages all the functions of your dishwasher, including water flow, temperature regulation, and cycle timing. If the control board malfunctions, it can prevent the dishwasher from running properly, affecting cleaning performance.

Why the Control Board Matters

• The control board is responsible for the timing and sequencing of the wash cycle, including when to release detergent, heat the water, and activate spray arms.
• A malfunctioning control board can result in delayed wash cycles or inconsistent operation.

How to Inspect the Control Board

• Check for error codes displayed on the control panel. These codes can indicate issues with the control board.
• Listen for unusual behavior, such as the dishwasher not starting or stopping prematurely.
• Inspect wiring connections on the control board for damage or loose connections.

Signs of a Problem

If your dishwasher starts and stops unexpectedly, or if it doesn’t progress through the wash cycle, the control board could be the issue.

Regular Maintenance Tips to Keep Your Electrolux Dishwasher Cleaning Effectively

• Clean the filters every few uses to prevent food buildup.
• Inspect the spray arms for blockages or signs of wear.
• Check the water temperature to ensure it’s at least 120°F (49°C).
• Use high-quality detergent and a rinse aid to improve cleaning performance.
• Run a cleaning cycle monthly with dishwasher-safe cleaner to prevent mineral buildup.
