CDS‑200B ultrasonic cleaner - AKA James Ultra 7050 etc.

There are many versions of cheap Chinese ultrasonic cleaners, and a fair few share this design, with a removable tank with handle. There are also fixed tank versions which look to use the same basic layout and presumably the same PCBs.

I picked one up "spares or repair" on ebay, and the cleaner was dead, but the fuse wasn't blown.

A quick diode check revealed D7 was shorted. D7 is a 12V 1/2 Watt Zener. I had one in my stash, so this was about as close to a "five minute repair" as...

I bought an ultrasonic cleaner from ebay and after a couple of years it blew one of the driver boards fuse and a couple of diodes. I replaced the parts and it worked for a while then died again. Since then I have thrown out the board and just use one. The unit had 2 drivers and the good one drives 1 transducer only. The fried board was driving 2 transducers. The unit works on 1 transducer but is weak in power. I am tempted to connect the 2 transducers that were driven by the dead board. And leave the single disconnected. Not sure if it there is a fault in them and will just kill the driver. As...

After a not very cool noise and the display dimming my ultrasonic cleaner powered off. The display and fan work, just nothing happens when I press the ultrasonic button.
I think it's at least the triac that is at fault (on the small PCB), showing 57 ohms between pin 1 and 3 and possibly one of the relays (marked in red), I was hoping someone might advise. Thank you....

Hi,
I have had an iROBOT i7 with a camera error (error 68) version REV M, year 2018.

I bought a liquid damaged Mainboard with WiFi module, from the same vacuum cleaner, but a different year and a different version (REV G).
(This board does not respond, only the LEDs light up in a circle.
The liquid damage is catastrophic and restoration is impractical).
(I bought this board to get the WiFi module and camera).

The boards are completely different in the installation of elements, even the connector for the WiFi module is different.

If...
