How to change the Sealing Element and lid gasket

Changing the Sealing Element (Heating Wire) on Your DZ Vacuum Sealer

Changing the sealing element (heating wire) on your DZ vacuum sealer is a straightforward process if you follow these steps carefully:

Tools & Materials Needed

  • Replacement sealing element (heating wire)
  • Teflon tape (PTFE cover strip)
  • Screwdriver
  • Pliers
  • Scissors or utility knife

Step-by-Step Guide

1. Unplug the Machine

Before starting, ensure the vacuum sealer is completely powered off and unplugged for safety.

2.Open the Sealing Bar Assembly

Locate the sealing bar where the heating wire is installed. Depending on your model, remove any screws or clips securing the cover over the sealing bar.

3. Remove the Old Heating Wire

Carefully lift the Teflon tape covering the heating wire. Unscrew or unclip the old heating wire from its terminals on both ends. Take note of how it was installed for proper replacement.

4. Install the New Heating Wire

Align the new heating wire in the same position as the old one. Secure both ends of the wire to the terminal connections. Make sure the wire is tight and not loose, as slack can cause uneven sealing.

5. Replace the Teflon Tape

Cut a new piece of Teflon tape and place it over the heating wire. Ensure it is smooth and properly aligned to prevent sealing issues.

6. Reassemble and Test

Secure the sealing bar cover back in place. Plug in the vacuum sealer and test it with a bag to ensure proper sealing.

Tips for Better Performance

  • ✔️ Use the correct replacement wire for your DZ vacuum sealer model.
  • ✔️ Ensure the wire is tight and not overlapping to prevent burns or weak seals.
  • ✔️ Replace the Teflon tape every time you change the heating wire for best results.
  • ✔️ If the machine overheats or does not seal properly, check wire tension and connections.
