Error Code ER10

Washing Machine Error Code ER10 / Error 10 (Beko / Blomberg)

If your Beko or Blomberg washing machine display shows error code ER10 or the numerical designation Error 10, this is a serious indication of a major internal fault related to water containment. This error specifically signifies that the Aquastop safety system has been triggered and has shut down the appliance.

The activation of the Aquastop mechanism occurs primarily when the machine detects:

• A significant water leak into the appliance’s base pan (sump): This is the most common cause. A leak from an internal hose, a failing seal on the pump, or damage to the tub allows water to collect in the lowest point of the machine chassis.
• Activation of the float switch: A safety float switch is positioned within the base pan. When water accumulates, the float rises, mechanically or electrically tripping the Aquastop system and interrupting the washing cycle and water inlet.
• A potential water overflow detection: This implies that the water level sensor (hydrostat) may have failed or given an incorrect reading, causing the machine to overfill the drum until the excess water spills into the base pan.

This error is designed to prevent flooding and requires immediate investigation before the appliance can be used again.

What to do: Immediate Safety and Preliminary Inspection

The following steps are critical for ensuring safety and performing a preliminary check of the unit:

1. Turn off the washing machine immediately. Press the power button to cease all current operations, including any attempts by the machine to drain or fill, which could worsen the leak.
2. Unplug the appliance from the power outlet. Physically remove the main power plug from the wall socket. This ensures complete electrical isolation, which is absolutely crucial when dealing with potential water leaks near internal electrical components and wiring.
3. Check if there is water in the base pan. The base pan is located at the very bottom of the appliance chassis. Accessing this area may require carefully tilting the machine forward (if done gently) or removing a lower inspection panel. If water has pooled in this area, the float switch will remain elevated, preventing the error code from clearing. Carefully remove all accumulated water using a highly absorbent sponge, towels, or a wet/dry vacuum cleaner. The float switch must drop completely back down to its resting position.
4. Check for visible leaks. Once the base pan is dry, thoroughly inspect external components and easily accessible connections for the source of the leak. Pay specific attention to:
   • Supply Hoses: Check the main water inlet hoses connecting to the back of the machine for any signs of cracking, splitting, or weak points.
   • Inlet Connections: Ensure the fittings where the hoses connect to the appliance are secured tightly and that the rubber washers are intact.
   • Drain Hose: Inspect the integrity and connection points of the drain hose for any damage or seepage.
5. If you find a definitive leak source or suspect internal failure, contact an authorized repair technician. If the leak originates from an internal component—such as the pump, the motor seal, the tub gasket, or an internal circulation hose—do not attempt complex disassembly or repair yourself. Internal plumbing repairs require specialized knowledge and tools to ensure seals are correctly fitted and watertight.
6. If there is no visible leak, the problem may be with the water sensor or the float switch. If the base pan was dry when checked, or if the water was removed but the error returns immediately without a new leak, the problem is likely related to the electrical system (a stuck float switch or a faulty hydrostat sensor). In this scenario, where the fault is electrical rather than hydraulic, it is also essential and advisable to contact a qualified service technician authorized for Beko or Blomberg appliances.

Important Safety Notice: A leak, even a slow one, within the appliance chassis can cause serious long-term damage, leading to internal component corrosion, mold growth, and potentially hazardous electrical short circuits. Avoid using the washing machine completely until the precise source of the water infiltration is identified, professionally repaired, and the ER10 error code is fully resolved.
