About this topside/keypad

The Sundance Spas 880 Series Keypad 6600-858 is a genuine OEM spaside control panel designed for Sundance spa systems equipped with 2-pump configurations. This 12-button control interface provides complete command over your spa's essential functions including pump operations, lighting, temperature settings, and filtration cycles. The durable 880 series panel construction ensures reliable performance in wet spa environments while maintaining the sleek appearance that complements your Sundance spa design.

At Bubbles Supply, we guarantee this keypad delivers an exact fit for your Sundance spa system, backed by our comprehensive 1-year warranty and same-day shipping on most orders. The 6600-858 control panel connects directly to your existing spa pack wiring harness using standard Sundance connections. Before ordering, verify your current keypad displays the 880 series marking and confirm your spa operates with a 2-pump system to ensure proper compatibility and functionality.

Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

  • Keypad buttons unresponsive or require multiple presses
  • Blank or dim display with no readout
  • Spa functions cannot be controlled from the topside panel
  • Error codes displaying that cannot be cleared via keypad
  • Spa stuck in a single mode due to failed button inputs

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

  • Confirm your existing keypad is physically labeled or marked as 880 Series — do not assume based on spa model year alone
  • Verify your spa runs a 2-pump configuration, as this keypad is designed for that specific setup
  • Locate the SKU or part number on the back of your current keypad and confirm it matches 6600-858
  • Check that your existing topside cable connector is compatible — count pins and inspect connector housing before ordering
  • Inspect the topside cable for damage; a faulty cable can mimic keypad failure and may need to be replaced separately

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
