Samsung Washer Error Code 1E — What It Means & How to Fix It

What Does This Error Mean?

The 1E error means the water level sensor has failed. Your washer can't detect how much water is in the drum. The cycle will stop because the machine can't operate safely.

Affected Models

WF45R6100AW
WF50R8500AV
WF42H5000AW
Most Samsung front-load and top-load washers

Common Causes

Water level sensor (pressure switch) has malfunctioned
The air hose connecting the sensor to the tub is kinked or disconnected
Debris or buildup is blocking the pressure hose
Wiring between the sensor and main control board is damaged
The main control board itself has failed

How to Fix It

Unplug the washer from the wall outlet and wait 60 seconds.

This resets the control board and can clear temporary sensor glitches.
Plug the washer back in and try starting a new cycle.

If the error returns immediately, continue to the next step.
Check the small rubber hose connected to the water level sensor at the top of the machine.

You may need to remove the top panel. The hose should be firmly attached and not kinked or cracked.
Blow gently into the pressure hose to clear any blockage.

If air flows freely, the hose is not clogged. If it feels blocked, replace the hose.
If the hose looks fine, the water level sensor itself likely needs replacement.

This is best handled by a qualified appliance technician.

When to Call a Professional

This error usually requires professional repair. The water level sensor or its wiring needs inspection. Do not attempt to run the washer repeatedly with this error. Expect repair costs of $150–$350 depending on the part needed.

Frequently Asked Questions

Can I still use my Samsung washer with the 1E error?

No — you should not try to run the washer with this error. The machine can't measure the water level. It could overfill or run without enough water. Both situations can cause damage.

How much does it cost to fix the 1E error on a Samsung washer?

The water level sensor itself costs around $30–$80. With professional labor, expect to pay $150–$350 total. If the main control board is the issue, it could be more expensive.

Is the 1E error the same as the IE error on Samsung washers?

Yes — on some displays, 1E can look like IE. They are the same error code. Both point to a water level sensor problem.
