3 temperature and point names in the board
The dishwasher hardly get warm, and sometimes it got temperature error from the sensor, and this time it wasn't warm but just cold water inside.
After opening I can't finde the termperature sensor but i have access to the board and there I see some point (most related to relays) that i would like to know what they mean:
IV , SV ,DV ,1/2 ,DP , WP
There is also a point called FAN but I assume that there is a fan for the drying stage)
Hi @alcrepaircafe
What is the make and model number of the dishwasher?

it is a supermarket rebranded but i can find out the real brand or manufactor.
The board is a POWER CARD DW-8

What is the make and model number that the supermarket uses for the dishwasher?
Did you check the back of the machine to see if the original manufacturer has a label there somewhere? Look on some of the major parts as well, e.g. pumps and motors
Searching for the power board model number gives no results.
Guessing what the designations could mean may lead you astray but perhaps the following might be it but who knows as this is a total guess
IV = inlet valve
SV = ?
DV = Drain valve
1/2 = ?
DP = drain pump
WP = wash pump
Have you measured the resistance value of the heater element?

I haven measured the resistance yet because after opening the motherboard box, I applied new solder tin on some points, then dishwasher heated without error.
Also I took advantage of the machine working to place inside some anti-lime product.
So, it has worked, but I am not confident about being the final solution...
Anyway i am not confident about this being the solution
