About this topside/keypad

The Balboa ML551 Spaside Control (G8351) is a 7-button LCD control panel designed for Balboa-equipped hot tubs and spas. This OEM replacement control features a clear LCD display for easy temperature and function monitoring, giving you precise control over your spa's operations. The ML551 delivers reliable performance with intuitive button layout for jets, lighting, temperature adjustment, and system functions.

At Bubbles Supply, this genuine Balboa spaside control comes with our exact fit guarantee, same-day shipping on in-stock orders, and a full 1-year warranty for complete peace of mind. Our OEM parts ensure seamless integration with your existing Balboa control pack system. Note that this control requires the appropriate overlay (sold separately) for proper labeling and weather protection. Verify your current control's model number before ordering to ensure proper compatibility with your spa's control system.

Common symptoms this part fixes

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

  • Blank or unresponsive LCD display
  • Buttons not registering when pressed
  • Spa won't respond to temperature adjustments
  • Error codes stuck on display with no button response
  • Control panel cracked, water-damaged, or physically broken
  • Spa functions (jets, lights, blower) can't be toggled from topside

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

Before you buy — quick checklist

  • Confirm your existing spaside control is labeled ML551 — do not order by appearance alone
  • Verify the connector type and pin count on your current control's cable matches the G8351
  • Check that your spa's Balboa control pack supports the ML551 topside — not all Balboa packs are compatible with every topside model
  • Note that an overlay is sold separately and required for proper button labeling and weather protection — confirm the overlay part number before ordering
  • Inspect the topside cable for damage before replacement — a faulty cable can cause the same symptoms as a bad control panel

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