Welcome to Justanswer … my name is Kevin and I will help you today!
I’m sorry to hear you're having trouble with your appliance; I know that can be frustrating.
Hopefully, we can get this resolved quickly.
It seems water has leaked in the base of appliance and activated anti flood device.
You can unplug it and pull it out, then tip it backwards by around 45 degrees so excess water drains off completely.
Then clean the mesh filter inside, drain pump and check the waste pipe for any clogs.
If this is Integrated unit then remove the inspection panel and clean it with a sponge, make sure it is all dried up.
Then plug it back and see how it goes.
Let me know how it goes.
