Samsung dishwasher only does drain

Hi

Model is dw60m6050fw

When you turn it on it goes straight into drain mode.

After the 60 seconds is up the front panel is locked out but it's not the child lock

I have checked the leak detector thingy on the bottom and it's dry as a bone

I have checked it's actually draining by chucking a bunch of water in and popping the drain hose in a bucket and it's draining fine.

No error codes

Weird thing is if you turn it on and start pressing other buttons the drain mode doesn't come on until you stop.

Could this be a faulty front pcb thats thinking the start button is being held down?(This is how you start the drain mode)
