Easy Installation
Replacing your hot tub keypad is a straightforward process. First, ensure you turn off the power to your hot tub at the main circuit breaker to avoid injury. Access your spa's control box, unplug the old topside cord from the circuit board, and carefully wedge out the old panel without scratching the acrylic shell.
Clean the surface, route the new 7-foot cord through to your spa pack, and plug it into the designated jack. Control panels are mounted using the included double-sided sticky tape gasket. Once secured, peel off the protective backing and press your overlay firmly into place.
Frequently Asked Questions
How do I know if this topside control will fit my hot tub?
The best way to confirm compatibility is to check the part number on your existing topside control or your spa's control pack. The ML900 is specifically designed for Balboa EL and GL series systems. If you need hard to find part assistance, send us an email to fixmytub@gmail.com. Check your part number if known, or send us pictures, the make and model of the hot tub, and the serial number.
Does this control panel come with an overlay?
This specific ML900 replacement panel is sold without the overlay. Because different spa brands use different button configurations (ranging from 9 to 12 buttons) for the same underlying panel, you will need to apply the specific overlay that matches your hot tub's functions.
Can I upgrade my older hot tub control panel to this one?
If your spa is currently running a compatible Balboa GL or EL Series control system, the ML900 can serve as a direct replacement. Ensure that the panel dimensions (11-3/4" x 3-1/4") and the 8-pin Molex connector match your existing setup for a proper fit.
