We recently purchased the Creworks Ultrasonic Cleaner and it quit working after 2 uses. We ordered it on eBay and are working with the seller to get a new board but I wanted to see if we could repair it and it was a simple fix.
with a little knowledge and a few tools you can fix your ultrasonic cleaner too.
The are really simple in design, with a control board and power drivers. the first step is to see where you have power.
