How to Fix a Samsung Dishwasher 1E Error
A Samsung dishwasher throwing 1E (sometimes shown as an inlet fault) is telling you it did not sense the expected fill. Most 1E calls are supply-side — a closed valve, a kinked hose, low pressure, or a clogged screen — so work those first and only replace the inlet valve, part DD62-00084A, if the cheap checks come up…
The control watches for water arriving on schedule; when it does not, it stops and posts 1E instead of running dry. That means the fastest fixes cost nothing, and the valve — the part everyone wants to blame — is actually the last suspect, not the first.
Work the list in order and stop the moment the machine fills normally; there is no reason to open the door panel and meter a valve if a half-closed shutoff was starving the fill all along. Keep the bucket and towel handy at every water-line step, because even a "closed" supply holds a cupful that will find your floor the instant a fitting cracks loose.
What to have on hand#
A flashlight, adjustable pliers, a small bucket, and a towel cover most of this, with a multimeter optional for testing the valve coil. You will not need parts up front: most causes are supply-side. If the valve does turn out to be dead, order DD62-00084A (it varies by model).

Safety note#
Close the water supply valve before disconnecting any water lines. For electrical testing of the inlet valve, disconnect power at the circuit breaker first.
Diagnose from cheapest to deepest#
- Check the household supply valve. Under the sink, make sure the dishwasher's shutoff is fully open — a half-turned valve chokes the fill and mimics a dead inlet valve.
- Check the supply hose for kinks. Ease the machine out and look for a hose pinched behind a foot or crushed against the cabinet; straighten or reroute it.
- Check water pressure. Samsung fills need real pressure. Run the kitchen faucet full-bore; a weak stream hints at a whole-house pressure or supply problem, not the dishwasher.
- Clean the inlet screen filter. Where the fill hose meets the valve there is a fine mesh screen that scale and grit clog over time. Pull the hose (bucket ready) and rinse or gently brush the screen clear.
- Rule out household water issues. A softener mid-regeneration or a recently shut-off main can starve the fill for a cycle — that explains a 1E that appears only at certain times of day.
- Test the inlet valve electrically. With power off at the breaker, put your meter across the valve coil terminals. An open or wildly out-of-range reading means the solenoid is dead and the valve is the fault.
- Check for a mechanical fill-valve failure. A valve that reads fine electrically can still stick shut from mineral lock; if it clicks but never passes water at pressure, treat it as failed.
- Replace the inlet valve if needed. Shut water and power, unclip the harness, release the mounting screw, swap in DD62-00084A, and reconnect the hose and wiring in the same order.
- Verify the fix. Restore water and power, start a cycle, and confirm a steady fill with no return of 1E within the first few minutes.
Safety First — Know the Risks
Live 120V wiring in a wet environment is one of the most dangerous DIY scenarios. Water + electricity = serious shock risk. Our techs are licensed and insured — let them handle the risk.

When to call a pro#
If pressure and the valve both test good but 1E persists, the flow sensor or the main control board may be misreading the fill, which is a diagnostic step best left to a technician. A related 3E or 5E showing up alongside 1E also broadens the fault beyond a simple valve.
