Notes

4C on a Samsung dishwasher means: Water supply error — the dishwasher is not receiving enough water.
The same fault appears as 4E on other Samsung models. The code changed between generations; the fault did not. A search that turns up nothing under one spelling will usually turn up plenty under another.
Across brands this is the same fault as LG IE. No manufacturer publishes that mapping, because each one documents only its own codes — but the underlying failure and the order you check things in are identical.
Work the steps in order. They are arranged so the free checks come before the ones that cost money, which is also the order in which the causes actually occur.
Clearing the code is not fixing it. Every one of these machines will show the code again on the next cycle if the underlying condition is still there. A code that clears and stays away means the fix worked; a code that clears and comes back means it did not.
