Error F04 in Siemens washing machine

How to eliminate F04 error in Siemens washing machine?

Error: F04

Description: Water drainage problem.

Causes

• Drain pump filter clogged or obstructed.
• Drain pump propeller stuck or restricted.
• Hose connected to the drain pump bent, folded, or blocked.
• Thick hose leaving the washing machine tub (Cuba) obstructed.
• Electrical failure in drain pump wiring or electronic module.

Step-by-step solution

1. Disconnect the washing machine: Unplug the appliance from the electrical outlet to ensure safety.
2. Close the water intake: Turn off the water supply valve connected to the washing machine to prevent water flow during maintenance.
3. Open the filter cover: Locate and open the filter lid at the bottom front of the washing machine.
4. Remove and clean the drain pump filter: Take out the filter plug and inspect inside for lint, debris, or any blockages. Clean thoroughly if clogged.
5. Check the pump propeller: In the same filter hole, inspect the drain pump impeller (propeller) to ensure it is not stuck or obstructed by residues. Remove any debris found.
6. Inspect the drain hoses: Tilt the washing machine back carefully and check the hose connected to the drain pump for kinks, folds, or obstructions. Also, check the thicker hose that leads away from the tub (Cuba) for any blockages.
7. Verify electrical supply to the drain pump: Using a voltmeter, measure the voltage arriving at the drain pump.
   • If there is no voltage, the issue might be with the electronic control module or wiring, requiring professional diagnosis.
   • If voltage is present, the pump itself is likely faulty and should be replaced.
