Samsung 4E — a dish care machine not getting enough water
Samsung's own troubleshooting page defines 4E and 4C in plain terms: the dishwasher is not getting water at the pressure or temperature that it needs, which on a new hookup points first at the supply connection rather than a part.

What to do when 4E shows on the applianceKind of codeWater supply and drain
The new appliance is reporting what it gets from the water connections behind it. A no-water or slow-fill message on the first fill usually means the supply valve is still closed or only half open, or the new line kinked when the unit slid back; a drain message means the drain hose is pinched, pushed too deep into the standpipe, or looped higher or lower than the installation instructions allow. Open the valve fully, straighten the hose, set it to the height the manual gives, and run the cycle again.
Usually leads toWater supply and shutoff connection
New supply lines from a working quarter-turn stop to each water appliance, tested under pressure.

A water leak after an install is water on the floor, a drip behind the kick plate or a wet cabinet in the first days after a new appliance was connected to water or a drain.

Before you book,
in this order.
Each step comes from Samsung's own guidance for 4E on its appliances. Follow it to the end: the last card says whether this is a visit.
Confirm the hot water supply valve behind the unit is fully open.
Check that the house water heater is set to the temperature Samsung's install manual specifies for the unit.
Inspect the inlet line for a kink left over from fitting the unit into its opening.
Run a normal cycle once the supply is confirmed before assuming any part is involved.
Still there?
It usually turns into water supply and shutoff connection. Book with the code and the model number.
What not to do
4E does not by itself mean the water inlet valve has failed. Samsung's own wording is about pressure and temperature reaching the unit, which a fresh hookup's supply valve and water heater setting can fully explain.

Can I clear 4E myself?
Why does a brand-new dish care machine show 4E on its first cycle?
Does 4E mean the unit needs its own dedicated hot water line?
Could low house water pressure overall cause 4E even with the valve open?

Still showing 4E?
A booking moves faster with three things: the message exactly as the display shows it, the model number from the carton or the rating plate, and the moment it first appeared. With those, the office can tell whether it is a setup step or a connection to put right, and send the part that fixes it.
