Frequently Asked Questions

Does this power supply include a cable?
No. This unit requires a separate power cable. If you also need a replacement cable, please add the appropriate Maytronics cable to your order.

How do I know if my Dolphin power supply needs replacing?
Common signs of a faulty PSU include the cleaner not powering on at all, the unit cutting out mid-cycle, error lights on the PSU, or physical damage to the unit. If the cable and cleaner are confirmed working but the unit won't start, the PSU is likely the cause.

Is this a genuine Maytronics part?
Yes. Part No. 99956033-AU-15 is a genuine OEM Maytronics replacement power supply, not an aftermarket substitute.

Will this suit my Dolphin cleaner?
This PSU suits the Dolphin X40 Plus, S300i, S200, DB1, DB2, and Pentair Prowler 920. If your model is not listed, contact us with your cleaner's model number before ordering to confirm compatibility.

What does the Bluetooth do on this power supply?
The Bluetooth connectivity allows compatible Dolphin models to be controlled and scheduled via the Maytronics MyDolphin app on your smartphone. Not all compatible models use the Bluetooth feature — refer to your cleaner's manual to confirm app support.
