Error Code Cb

Error Code Cb - Water Level Too High

This error code, Cb, signifies that the washing machine has detected an excessively high water level. This situation is critical because the appliance’s safety mechanism has been triggered, indicating that the water level has exceeded the maximum safe limit 5 times during the current cycle. This repeated triggering suggests a persistent issue that needs immediate attention to prevent potential water damage or further appliance malfunction.

To address this error, please follow these troubleshooting steps:

• Check the Water Supply:

  • Why: An incorrect water supply setting or a faulty inlet valve could lead to an overfill condition.
  • How:
    • Ensure the water tap connected to the washing machine is fully open.
    • Verify that the selected wash program is appropriate for the load size and type, as some programs have different water intake requirements.
    • If the issue persists, there might be a problem with the water inlet valve itself, which may require professional inspection or replacement.

• Check the Drainage:

  • Why: If the machine cannot drain water effectively, the water level will rise beyond the normal operational limits.
  • How:
    • Drain Hose: Inspect the drain hose for any kinks, bends, or blockages that could impede water flow. Ensure the hose is not inserted too far into the standpipe or drain, as this can create a siphoning effect that prevents proper drainage. The recommended height for the drain hose is typically between 60 cm and 100 cm from the floor.
    • Drain Filter/Pump Filter: Locate the drain filter, usually found at the bottom front of the machine behind a small access panel. Carefully open the panel (place a towel or shallow container underneath to catch any residual water) and unscrew the filter. Clean out any lint, coins, debris, or other obstructions that may be present. A clogged filter is a very common cause of drainage issues.
    • Drain Pump: After cleaning the filter, ensure the drain pump impeller (located behind the filter) can spin freely. If the impeller is damaged or seized, the pump may need to be replaced.

• Problem with the Water Level Sensor:

  • Why: The water level sensor (also known as a pressure sensor or pressure switch) is responsible for measuring the amount of water inside the drum. If this sensor is faulty or its associated air trap is blocked, it can send incorrect readings to the control board, leading the machine to believe there is less water than there actually is, or vice versa, causing an overfill.
  • How: Inspect the thin tube that connects the water level sensor to the drum. Ensure this tube is not kinked, blocked with detergent residue or limescale, or detached. If the sensor itself is suspected of malfunction, it will require testing and potential replacement by a qualified technician.

• Problem with the Drain Pump:

  • Why: As mentioned in the drainage check, a faulty drain pump is a direct cause of poor or no drainage, leading to the water level rising.
  • How: If the filter is clear and the drain hose is unobstructed, but the machine still fails to drain, the drain pump motor may have failed, or its internal components may be damaged. This would necessitate a repair or replacement of the pump.

If, after performing these checks, the error code Cb persists, it is recommended to contact a qualified appliance service technician for further diagnosis and repair.
