My Samsung dishwasher normal wash light is blinking. I have checked for hose kinks and leaks. I have raised the drainage hose to be higher than the plumbing connection. Still throws code. And will try to drain even with the door open. Unplugging and plugging back in doesn't help. Now what?!

I just read this for the same problem: push sanitize, then heat and dry, sanitize, heat and dry, sanitize, heat and dry, cancel, then open and close the door. It worked. The dishwasher is running correctly even as I type this.

The drain valve is stuck open. This is electrically operated, but may have some debris inhibiting movement. If you can physically move it (with the power off) this should repair the problem.

This has happened to me twice. Both times I found the drain pump seized up with
1st time) The right rim from a pair of reading glasses
2nd time) A plastic toothpick
Both times the object was in the discharge port of the pump. You can see this by lifting the check valve with the pump removed. Removing the pump is simple. Unplug the washer. You have to remove the drain line from where its attached to the rear of the machine (one screw) to remove the rear access panel which slides into upper and lower slots. You will see the pump with an inlet and discharge line attached. The lines have simple squeeze clamps. When you remove the lines, you will drain the wash basin so have towels and a squeegie handy. Remove both lines and wait until the basin drains. When it stops draining remove the pumps electrical connector by squeezing the release catch on it while pulling it. The connector can only go on one way. Remove the 3 hold-down bolts on the pump baseplate. Remove the pump and lift open the discharge check valve and you'll find something there I guarantee it. Remove with needle nose pliers and re-assemble in reverse order.
This is actually a good design because the computer protects the pump by sensing a higher than normal current draw when foreign debris gets jammed in it. It will trigger the ND (No Drain) code and sometimes lock the door. Always check this first before you call the expensive repair man. If its not a jammed pump it will most likely be the control panel/processor. Good luck and always clean out pockets before loading the washer to prevent this,

Make the standpipe longer (the black pipe).
