Why is my Hoover WH20400 Steam Cleaner not producing steam?
- SSteven DavisJul 31, 2025
If your Hoover Steam Cleaner isn't producing steam, consider these possibilities: 1. The twin tank might be empty. Please refill the twin tank. 2. The twin tank may not be correctly attached. Ensure the tank is fully seated. 3. A clogged water filter may need to be cleaned or replaced. 4. The thermal protector may have turned off the pump. Unplug the steam cleaner and allow it to cool down. 5. The steam path may be blocked. Please refer to the “Clearing Blockages” section.
