About this circuit board

This Marquis Spa circuit board (part number MQ2KUR2A) is an OEM replacement control board designed for EL2000 systems in Marquis spas. This genuine Balboa-manufactured Mach 3 circuit board serves as the central command unit for your spa's electrical functions, controlling pumps, heaters, lights, and filtration cycles with factory precision.

When your spa's control system fails, this exact-fit replacement ensures seamless compatibility with your existing setup. At Bubbles Supply, we guarantee this circuit board will fit your system perfectly, and we back every purchase with our comprehensive 1-year warranty. Plus, we ship same-day to get your spa running fast. Before installation, ensure power is completely disconnected and consider having a qualified technician handle the replacement, as improper wiring can damage sensitive electronic components.

Common symptoms this part fixes

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

  • Spa displays error codes and will not operate
  • Pumps, heater, or lights fail to respond to topside controls
  • Spa powers on but heater does not activate
  • Control panel is unresponsive or shows blank display
  • Spa trips GFCI repeatedly due to board fault
  • Spa functions cycle on and off erratically or without input

Before you buy β€” quick checklist

  • Confirm your spa uses an EL2000 control system β€” check the label on your existing board or control pack enclosure
  • Verify the part number MQ2KUR2A is printed on your current circuit board before ordering
  • Check that your topside control panel is compatible with the Mach 3 board β€” a mismatched topside can cause communication errors after replacement
  • Inspect wiring harness connectors for corrosion or heat damage before installing β€” a damaged harness can kill a new board quickly
  • Diagnose the root cause of board failure before replacing β€” water intrusion, power surges, or a shorted component elsewhere in the system can damage a new board if left unresolved

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