The dishwasher is out of warranty unfortunately.

The normal light keeps blinking after starting any cycle. It keeps blinking exactly as in the video here.
I got the dishwasher out and dried everything. When I tried to start another cycle, it took almost two minutes until the normal light returned to blinking again and making the sound like it is trying to drain. I can't figure out where is the source of the leakage.

Any help would be appreciated.

Hi, I'm attaching the service manual below.

Look on Page 28
Normal light blinking--->When the water leakage sensor date is equal to less than 3V for 2 seconds.

Possible Causes:
- The case brake fails to detect the pulse.
- The valve water is out of order.
- The overflow sensor is broken.
- There is a water leakage.

Look on Page 36
Check whether there is any trace of water leakage in the shutter.
Normal: No water leakage trace

Faulty: Check the leakage location. Replace the Faulty part.
Normal: Replace the Main PBA assy.D12

Here's the main PBA assembly for your model:

Thanks Jake, That was very helpful. I dried the dishwasher and then restarted it.
I noticed a leak in the water inlet valve. Is this something I can fix or I need to replace the whole water valve.

Appreciate your help.

I watched a video on a slightly different Samsung dishwasher about how to disconnect everything and pull the unit out. My units water hose isn't connected in the front like the video but the electrical wires are. How would I pull the unit out from the counter safely? Breaker off, water off, drain hose disconnected, panel covering electrical wires off. What next besides disconnecting wires?
