Hi everyone,

I have a Spectra Aqua Knight V3. A few drops of water got onto the control board and corroded one of the inductors. The display no longer works, so I can't select or set any program. The LEDs still light up, but they're stuck on a fixed output.

Does anyone know if a replacement control board is available from the manufacturer? I emailed Spectra but have had no response so far.

If anyone has repaired one of these or knows where to source the board, I'd appreciate any pointers. Thanks.

You can try @_AV
Considering this light currently is around $100 well may be hard to justify the fix.
BUT.. not sure about Aliexpress or what you are offered..


It's everywhere..

Thanks a lot for the reply, appreciated.


Fair point on cost. I'm in Serbia, so shipping a board (or a whole new light) from pretty much anywhere would cost more than the light itself :D So at this stage it's honestly more curiosity, and I'd like to keep it as a backup or quarantine light if I can revive it. It's running on a wall timer on its fixed output for now, so I'm not in a bind.


I'll check the AliExpress link, thanks for that. @_AV, if you happen to see this, I'd really value your take on whether the board is repairable or where the part could be sourced. Thanks again, everyone.
