Answer to continue safely
Is it safe to keep using?
No. Without accurate water level monitoring, the dishwasher cannot control water intake properly. This could lead to underfilling (poor wash results) or overfilling (leak risk). Do not operate until the sensor is repaired.
Can I reset the code?
Yes. Turn off the circuit breaker for 5 minutes to reset. If 1E was a temporary glitch, it will clear. Persistent 1E requires sensor service.
When to stop immediately?
Stop if you notice: Water is leaking from under the dishwasher, The tub fills with more water than normal.
Symptoms You May Notice
Dishwasher stops mid-cycle
The machine halts during the wash or rinse phase when the control board cannot verify the water level.
1E error code on display
The digital panel shows 1E, preventing the cycle from continuing or starting.
Tub does not fill with water
The dishwasher may attempt to fill but stops prematurely because the sensor reports an incorrect level.
Water overflows slightly
If the sensor is stuck reading low, the valve may continue filling past the correct level before the error triggers.
Possible Causes
Blocked pressure sensor tube
The narrow rubber tube connecting the tub sump to the pressure switch clogs with food debris or detergent scale, preventing accurate pressure readings.
Requires ProfessionalFailed pressure switch
The electrical pressure switch can wear out and no longer respond to changes in water level pressure, sending a constant or no signal to the board.
Requires ProfessionalWiring issue
Corroded or loose wire connections between the pressure switch and the control board interrupt the sensor signal.
Requires ProfessionalSafe Checks You Can Do
-
1
Power cycle the dishwasher
Turn off the dishwasher circuit breaker for 5 minutes, then turn it back on. Start a new cycle to see if 1E clears.
Samsung dishwashers do not have a dedicated reset button — the breaker method is the standard reset procedure.

2
Check the dishwasher level
Place a spirit level on the door opening. Adjust the front leveling legs until the bubble is centered both side-to-side and front-to-back.
An unlevel dishwasher affects the water sump depth, which can confuse the pressure sensor.
Tools required
When to Call a Professional

- 1E appears on every cycle after power cycling
