How do I know which Sundance spa pump I need?

Frequently Asked Questions

How do I know which Sundance pump I need?

Check the white label on your current motor. Look for the Part Number (e.g., 6500-343), Frame Size (usually 48 or 56), and Voltage. It is vital to match the Voltage and Frame size exactly; Horsepower can vary slightly without issue.

Why is my Sundance spa showing a 'FLO' error?

A 'FLO' or 'FL1' error usually indicates a failed circulation pump (like the 6000-125) or a dirty filter. If the filter is clean and the small circulation pump isn't moving water, it likely needs replacement.

Can I use an aftermarket pump instead of OEM?

Yes, but it can be tricky.  Many Sundance spas pump have been discontinued and the exact replacements are hard to find.  It's a good idea to send detailed photos to a Sundance Spa parts specialist for a match up.
