as above sounds like an F1.
You have to make sure the area around and under the mains filter board is bone dry, and that the board has no corrosion/damage.
Once the board is out for inspection you can push a screwdriver under the board chassis gently and it will lift from the base so you can get some kitchen roll underneath .
Worth checking
1 Abnormal load ie something obstructing the lid closing properly.
2 Lid motors
3 Link support broken causing 1
4 Leak from inlet pipe/waste pipe mice like the waste pipe
5 air flap in spray arm
6 Impellor on motor loose
I love them and I get to work on them every day 🙂
