Whirlpool ADP4739SI Dishwasher Error F6: Programmer Damage & Triac Testing Queries

Hello everyone.
There is a problem with the Whirlpool ADP4739 dishwasher. The dishwasher draws water and, after about 2 minutes, drains and displays error F6. The programmer has found damage to the programmer. After opening the programmer, at least visually you cannot see any burned elements or paths. I checked the triac No. 1 (ACS 1086S S844) with a multimeter and they do not show short circuits. As for Triac No. 2 (ACS 120 07S), I'm not sure it's functional. When checking the multimeter I have set the circuit continuity (note). When I put the minus to the G foot and the plus to the T2, it is conduction as with triacs No. 1 but without taking the minus probe from G and by placing the probe to T1, there is conduction as if the triac was turned on. This phenomenon does not occur if I apply a plus probe to the G foot. It also does not occur with triacs No. 1. As for triac No. 3 (RNM P2F), it conducts in every position, but it is possible that without desoldering the measurements are incorrect and after the determinations I am not sure if it would be a triac. The resistors are all checked and hold resistance as normal by designation.
Checked micro switch on the water distributor valve in working order.
I am not an electronics specialist, so please be forgiving. What else and how can I check?
Thank you in advance for your help.
Regards.

Hello, check the hydrostat

Hello.
How? Is there any resistance testing?

If I'm not mistaken, there is an OVI sensor, it acts as a hydrostat, I am in the place of the filter at the bottom of the dishwasher, try to clean it only with a cloth, it's something transparent, plastic

Something seems to me that this is an Fb error, and this changes things a lot

Hello.
Micro switch tested and functional. This was a friend's dishwasher and I asked if it was sometimes just a Fb error because from the symptoms and description of another dishwasher 2 minutes matches Fb.
I am adding a description

If Fb, it's something to exchange https://north.pl/karta/zawor-przelaczajacy-pompy-do-zmywarki-481010745146,707-TL-0532.html

Is it possible to check this valve without taking it apart? I remember when I was checking the micro switch there were probably two diodes and under this metal frame I think the winding.

This valve has a seal on the shaft and is often water permeable, which also contributes to incorrect operation. So, you have to replace the microswitch and sealant (it's hard to get it).
It is easier and safer for a layman to replace the entire valve - you need to look for the cheapest on the network.

Hello.
It is unlikely to be the fault of this valve. I undressed it as I was checking the micro switch. Dry inside, no sign of water ingress.
