Just repair my neighbor's aquabot. The AS06080SP Pump was not turning at all.
Opening the pump: - all power FETS were fine. - the main IC (U1) is a MC33033DW chipset. Looking at the datasheet and checking the 20 pins, I notice that VCC was not provided. - The cause was D1 (Diode) which was broken.
Replacing the diode with a standard one (0.5V drop) and the pump is working again...
This diode is not supposed to receive a high current (20 mA MC33033DW VCC current), so I don't have a lot of clues concerning the reason of issue...

Problem with motor board by: Alessandro
I wanted to ask you if trying the card for a few seconds without immersing it in the oil is normal which immediately becomes very hot, in particular the two large resistances

No information on each transistor by: Gerard
Hi all Is there a way to know the place where the different transistors should be installed? Mines haven't got any inscription on it. Tia
