Diverter valve is hard to turn or leaks water around the handle.

Safety first: Turn off power and avoid using the spa while the diverter is disassembled.

• Remove handle and cap: Unscrew the diverter cap and pull out the internal diverter assembly according to Arctic Spas instructions.
• Inspect and clean: Remove debris and scale from the valve body and diverter gate. Soak parts in a descaling solution if needed.
• Replace seals: Install new O-rings and seals from an Arctic Spas diverter rebuild kit.
• Reassemble and test: Reinstall the diverter, tighten the cap, and test for smooth operation and leaks.
