Error Code ER06

Washing Machine Error Code ER06: Problems with the Motor or Tachogenerator

Unfortunately, your Beko or Blomberg washing machine is displaying error code ER06. This is a critical functional error indicating that the appliance’s control board (PCB) is not receiving the correct feedback regarding the motor’s rotation or speed, or the motor is unable to start/maintain rotation. This usually points to a fault within the motor assembly itself, the associated wiring harness, or the tachogenerator (a sensor component essential for accurately measuring motor speed).

What to do?

1. Safety first: Disconnect Power

   • Before attempting any inspection or repair, always completely unplug the washing machine from the mains power outlet. If the appliance is hardwired, switch off the corresponding circuit breaker. This step is crucial to prevent electrical shock and further damage to the sensitive electronic components.

2. Visual Inspection of Wiring and Connections

   • Locate the main motor, typically situated at the bottom rear of the drum.
   • Carefully trace the wiring harness connecting the motor assembly to the control board (PCB) and the specific, smaller wires leading to the tachogenerator.
   • Look specifically for any wires that appear loose, disconnected, frayed, chafed (where insulation is worn down), or showing signs of burning or melting, particularly near terminal blocks or plastic connectors.
   • Ensure all electrical connectors are seated firmly and securely. A poor contact can easily trigger the ER06 error.

3. Inspect and Replace Carbon Brushes (If Applicable)

   • Note: This step applies specifically to universal motors (brushed motors). Accessing the brushes usually requires removing the back panel of the washing machine and potentially the motor itself (consult your detailed service manual).
   • The carbon brushes deliver electrical current to the motor’s armature and wear down naturally over the lifespan of the appliance. Severely worn brushes are one of the most common causes of motor failure errors like ER06.
   • Examine the length of the brushes. If they are worn down significantly (generally less than 1.5 cm or 1/2 inch remaining), or if they exhibit chipping, cracking, or uneven wear, they must be replaced.
   • Always use new carbon brushes that are the exact size and specification required for your specific Beko or Blomberg motor model.

4. Test the Tachogenerator (Speed Sensor)

   • The tachogenerator (or tacho coil) is a small sensor usually located at the opposite end of the motor shaft from the pulley. Its function is to provide crucial feedback to the control board about the motor’s speed.
   • Visually inspect the sensor and the small magnet on the motor shaft it reads; ensure there is no debris, rust, or physical damage.
   • Use a multimeter set to measure resistance (Ohms). Disconnect the tachogenerator’s wires from the main harness and measure the resistance across its two terminals.
   • Compare the measured resistance value to the manufacturer’s specified range (typically found in detailed service manuals). If the multimeter shows an open circuit reading (infinity or OL) or a dead short reading (0 Ohms), the tachogenerator is faulty and needs to be replaced.

5. Attempt System Reset

   • Once all inspected components have been resecured or replaced, plug the washing machine back into the power outlet.
   • Attempt to clear the error code by performing a system reset or running a diagnostic cycle. Refer specifically to your appliance’s operating manual for the exact key press sequence required to clear stored fault codes and reinitialize the system.

When to call a technician?

If the error code ER06 persists after thoroughly checking and replacing the carbon brushes and/or the tachogenerator, or if you are unsure about any of the diagnostic steps involving electrical testing, professional assistance is required.

• Complex Internal Failures: If the motor and tachogenerator appear functional, the cause may be a failure in the main electronic control board (PCB) or a severe internal winding failure within the motor itself.
• Specialized Motors: If your appliance uses a brushless DC (BLDC) or inverter motor instead of a traditional universal motor, the diagnosis procedures are specialized and should be handled by an authorized technician.
• Safety Concerns: If you are uncomfortable working with internal wiring or high-voltage components, please contact a certified Beko or Blomberg repair technician. A professional can accurately diagnose the root cause of the problem using specialized tools and perform the necessary repairs safely.
