SEE REPLACEMENT PART: OBSOLETE

Hydro-Quip B-Series 2-Speed Extender Replacement Spa Circuit Board (33-0029-K) is a replacement electronic control component used to restore spa or pool equipment communication, switching, and operating logic when the original board has failed or become unreliable. Part number 33-0029-K should be matched closely to the existing system, revision, voltage, keypad style, and connected equipment before installation.

This Hydro-Quip part is best suited for service repairs where exact board compatibility matters more than general appearance. When replacing a circuit board, compare connector locations, labeling, software or revision notes, sensor requirements, and any included transformer or accessory details. A careful match helps prevent nuisance errors, non-responsive controls, incorrect pump operation, and avoidable repeat service calls.

Because spa control systems often changed over time, the safest approach is to confirm the printed part number and system model directly from the existing component. Installation should be handled with power fully disconnected and by a qualified technician familiar with electrical service work around water-bearing equipment.

  • Replacement control component for compatible spa or pool systems
  • Match part number, voltage, connectors, and revision before purchase
  • Helps restore equipment control, communication, and operating functions
  • Recommended for professional installation with power disconnected
  • Useful for service repairs where OEM-style fit is required
