Match your pump label: Dynasty Spas uses the LX 56WUA400 on many models. Before ordering, confirm on your old pump’s label: 1-speed, 230V, 12 amps on high speed, 56 frame, 2" intake and 2" discharge. Always replace a pump with the same amperage to protect your spa pack and keep jet pressure right.
Cord and gaskets: Dynasty’s factory pump came with an 8 ft 4-pin AMP cord. If your replacement arrives without a cord, reuse your existing one. Replace the 2" union gaskets when you change the pump.
*Manufacturer reserves the right to make production changes. Actual product received may vary slightly in appearance but the function remains the same.
✅ Not Sure It Fits? Verify Before Ordering
Hot tub part compatibility can vary by spa brand, model, year, serial number, control system, and part revision.
To help us identify the correct replacement part, please send clear photos of:
- Your existing part label or sticker
- Your spa serial number sticker
- The equipment area or installation location (if accessible)
EZ Hot Tub Parts can help confirm fitment before you order and help reduce costly returns.
Dynasty’s build sheet for your serial number lists the exact factory parts. Send us your Dynasty serial number (on the metal tag in the equipment area) or photos of the label through the fit-check form above and we’ll confirm before you order.
Look at the label on your old pump: a 2-speed pump lists two amp ratings (12 / 4.4 A); a 1-speed lists one (12 A). Many Dynasty spas have one of each.
