Vacuum System Repairs
The vacuum system of the Tennant T7 is essential for maintaining a clean environment. When issues arise, knowing how to troubleshoot can save time and money. This section will guide you through common problems and solutions.
Loss Of Suction
If your Tennant T7 is experiencing a loss of suction, it can be due to several reasons. Begin by checking the vacuum motor. Ensure it is functioning properly. A faulty motor can lead to reduced suction power.
- Inspect the vacuum fan for damage or debris.
- Verify the vacuum seal is intact and not worn out.
- Check the recovery tank lid. It must be properly closed and sealed.
Another cause of suction loss can be a blockage in the system. Next, we’ll look at clogged hoses.
Clogged Hoses
Clogged hoses are a common issue that can affect suction. Inspect the hoses for any blockages or debris. Use a long, flexible brush to clear any obstructions.
- Disconnect the hoses from the machine.

Non-responsive Buttons
Non-responsive buttons can be frustrating. First, check if the buttons are physically stuck. Clean around the buttons to remove any debris. Sometimes, dirt can block the buttons from working.
If cleaning doesn’t help, inspect the wiring behind the control panel. Loose or damaged wires can prevent buttons from functioning. Secure any loose wires and replace damaged ones.
If the problem persists, the control panel might need a reset. Refer to your Tennant T7 troubleshooting manual for reset instructions. Follow the steps carefully to avoid further issues.
- Check for stuck buttons
