Beko Dishwasher Error Codes

In this guide, we’ll explain the most common Beko dishwasher error codes, what they mean, their likely causes, and how to troubleshoot them. Beko dishwashers use diagnostic codes to detect problems in water filling, draining, heating, sensors, motors, leaks, and electronic control systems.

Common Beko Dishwasher Error Codes

E01: Overflow Error

This error indicates that your dishwasher has detected an overflow of water. The system will enter standby mode for 2 minutes, during which the drain pump automatically activates. If the overflow signal persists after this period, the E01 code (or “Call Service”) will appear, and the control board will become unresponsive except for the ON/OFF button.

Possible Causes:

• Damaged wire harness connector.
• Malfunctioning overflow float mechanism.
• Faulty overflow float switch contact.
• Flowmeter malfunction.
• Water inlet valve failing to shut off.

Solutions:

1. Inspect the Overflow Level Gauge: Ensure it’s not stuck or obstructed.
2. Locate and Repair Leaks: Identify the source of the water overflow. Repair the affected area and replace any damaged components as necessary.
3. Verify Float Installation: Confirm the overflow float is correctly installed and moving freely.
4. Test the Overflow Microswitch:
   • Measure the resistance across the microswitch terminals.
   • When the switch is “normal” (not triggered), you should see a very low resistance (approx. 0.1−1.0Ω).
   • When “engaged” (triggered by an overflow), the resistance should be infinite (∞Ω or OL – Open Line).
   • If these readings are reversed or incorrect, replace the microswitch.
5. Check Water Inlet Valve: If the valve isn’t effectively stopping water flow, it needs to be replaced.

E02: No Water Error (or Insufficient Water)

Related Error Codes:

• E07: Water inlet valve error.
• E15: Flowmeter error.

This error indicates that the dishwasher isn’t detecting sufficient water intake. The flowmeter, which counts the liters of incoming water via electronic pulses, is monitored during the “Water Inlet” phase. If no pulses are detected by the main board, the E02 (or E07/E15 or “Call Service”) code appears. The dishwasher will pause operation until the water signal is detected or the error is resolved.

Possible Causes:

• Damaged wire harness connection.
• Clogged water valve filter screen.
• Faulty water inlet valve.
• Malfunctioning flowmeter.

Solutions:

1. Check Wire Harness Connection: Ensure all connections are secure.
2. Verify Water Tap: Make sure the water supply tap to the dishwasher is fully open.
3. Clean Inlet Filter Screen: Sediment and debris can block water flow. Clean the filter screen on the water inlet valve thoroughly.
4. Test Water Inlet Valve Resistance:
   • Using a multimeter, measure the resistance of the water inlet valve.
   • A healthy valve should have a resistance of approximately 3680Ω.
   • Readings near 0.1−1.0Ω or infinite (∞Ω / OL) indicate a faulty valve that needs replacement.
5. Inspect Flowmeter:
   • Visually check the flowmeter’s turbine to ensure it spins freely and isn’t obstructed.
   • Verify that the flowmeter’s reed switch is receiving 5V. If not, the main PCB may be faulty.

E03: Heating Error

The NTC (Negative Temperature Coefficient) sensor monitors the water temperature. If the temperature rises by less than 1°C within 3 minutes during the heating phase, the E03 error will trigger. The dishwasher will skip the heating phase and continue the program.

Solutions:

1. Check Wire Harness and Connections: Ensure all connections related to the heating circuit are secure.
2. Test Heater Thermostat Resistance:
   • At 100°C, the heater thermostat should have a very low resistance (approx. 0.1−1.0Ω).
   • An infinite resistance (∞Ω / OL) indicates a fault.
3. Verify Thermal Fuse Protection:
   • At 230°C, the thermal fuse protection should also show very low resistance (approx. 0.1−1.0Ω).
   • An infinite resistance (∞Ω / OL) indicates a blown fuse.
4. Check Heater Resistance:
   • The heating element itself should have a resistance of approximately 30Ω.
   • Readings near 0.1−1.0Ω or infinite (∞Ω / OL) suggest a faulty heater.

E04: Turbidity Sensor Error

Your dishwasher uses the turbidity sensor to determine the soil level of the water and adjust the wash cycle accordingly (auto-cycling). If the main board doesn’t receive appropriate data from the turbidity sensor, an E04 error occurs. When this fault appears, the auto cycle will typically run as if intensive dirt has been detected.

Solutions:

1. Check Sensor Wire Harness Connector: Ensure a secure connection.
2. Clean Turbidity Sensor: The sensor can become fouled with debris. Gently clean it.
3. Replace Turbidity Sensor: If cleaning doesn’t resolve the issue, the sensor itself may be faulty.

E05: 3-Way/Multi-Valve Error (Diverter Valve Error)

This error relates to the diverter valve, which is responsible for directing water flow to either the upper or lower spray arms. An E05 error appears if the dishwasher doesn’t receive the correct position signal from this valve.

Solutions:

1. Check Diverter Wire Harness Connector: Ensure the connection is secure.
2. Test Diverter Micro-Motor Resistance:
   • Measure the resistance of the diverter micro-motor.
   • It should be approximately 9200Ω.
   • Readings near 0.1−1.0Ω or infinite (∞Ω / OL) indicate a faulty motor.
3. Check Diverter Microswitch:
   • When “engaged” (activated), the microswitch should have very low resistance (approx. 0.1−1.0Ω).
   • When “normal” (not activated), it should show infinite resistance (∞Ω / OL).
   • Incorrect readings suggest a faulty switch.

E06: NTC Sensor Error

The NTC sensor measures the water temperature inside your dishwasher. An E06 error occurs if the control system detects an open circuit (no continuity) or a short circuit (unintended continuity) within the sensor.

Solutions:

1. Check Sensor Wire Harness Connector: Ensure the connection is secure.
2. Test Thermistor Resistance:
   • Measure the resistance of the NTC sensor.
   • At 20°C (room temperature), it should be approximately 60000Ω.
   • Infinite resistance (∞Ω / OL) indicates an open circuit; near 0Ω indicates a short circuit. Replace the sensor if abnormal.

E08: External Board Communication Error

Related Error Codes:

• E09: Display board communication error.
• E10: Conductivity board communication error (The conductivity board helps adjust water hardness and prevent glass corrosion).

These errors indicate a loss of communication between the main control board and various other boards within the dishwasher.

• E08: Main board and external board communication failure.
• E09: Main board and display board communication failure.
• E10: Main board and conductivity board communication failure.

Solutions:

1. Check Wire Harness Connections:
   • Verify the connection between the external board and the main PCB.
   • Verify the connection between the display board and the main PCB.
   • Verify the connection between the conductivity board and the main PCB.

E11: Conducto Probe Open Circuit Error

Related Error Code:

• E12: Conducto probe short circuit error.

These errors indicate issues with the conductivity probe, which monitors water hardness.

Solutions:

1. Check Probe Wire Harness Connector: Ensure a secure connection.
2. Replace the Conductivity Probe: If the connection is good, the probe itself is likely faulty.

E13: Pressure Switch Error

If the dishwasher’s control system doesn’t detect the pressure switch in the “ON” position, despite having over 2.8 liters of water inside, an E13 error will occur. When this happens, the heating phase will be skipped, and the program will continue.

Solutions:

1. Check Pressure Switch Wire Harness Connection: Ensure a secure connection.
2. Replace the Pressure Switch: If the connection is good, the pressure switch is likely faulty.
3. Replace Flowmeter (If Error Persists): In some cases, a faulty flowmeter can contribute to this error.

E14: Drain Filter Error

Related Error:

• E16: Drain pump error.

These errors indicate a problem with the dishwasher’s drainage system, either due to a clogged filter or a faulty drain pump.

Solutions:

1. Clean the Filter: Thoroughly clean the dishwasher’s drain filter.
2. Clear the Drain System: Check for any blockages in the drain hose or sink connection.
3. Check Connectors: Ensure all electrical connectors to the drain pump are properly seated.
4. Test Drain Pump Resistance:
   • Conventional Drain Pump: Should have a resistance of approximately 180Ω.
   • BLAC Drain Pump: Measure resistance between phases (U and V, V and W, W and U); each should be between 168 and 282Ω.
   • Readings near 0.1−1.0Ω or infinite (∞Ω / OL) indicate a faulty pump.

E17: Automatic Detergent Dosage Position Error

Related Error Code:

• E18: Automatic Detergent Dosage Motor Continuous-Run Error.

These errors relate to the automatic detergent dispenser.

• E17: The sensor cannot confirm dosing, even after the expected dosing period.
• E18: The sensor (reed switch or optical rinse aid sensor) detects detergent dosing when it shouldn’t be happening.

Solutions:

1. Check Wire Harness Connection: Ensure all connections to the dispenser are secure.
2. Check/Replace Dosing Reed Switch: This sensor often confirms the dispenser’s position.
3. Test Dosing Motor (Wax Motor) Resistance:
   • Measure the resistance of the auto-dose wax motor.
   • It should be approximately 2100Ω.
   • Readings near 0.1−1.0Ω or infinite (∞Ω / OL) indicate a faulty motor.

E23: Circulation Pump Communication Error

Related Error Code:

• E24: Circulation Pump Error.

These errors indicate a problem with the dishwasher’s circulation pump, which sprays water during the wash cycle.

Solutions:

1. Check Wire Connection: Verify the connection between the pump motor board and the main PCB.
2. Test Motor Resistance:
   • Measure the resistance between the phases of the circulation pump motor.
   • It should be approximately 56Ω.
   • Readings near 0.1−1.0Ω or infinite (∞Ω / OL) indicate a faulty motor.
3. Check/Replace Pump Motor Board: If the motor tests fine, the dedicated pump motor control board might be faulty.
