GE Washer E23 Error: Flood protection drain active
This guide covers GE washer E23 error in detail to help you diagnose and resolve the issue. What Does GE Washer Error Code E23 Mean? Error code E23 is the flood-protection drain alarm on GE Profile PFW950, PFW870, and GFW front-load washers. The control board monitors the water level even when idle. If it detects […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. E23 indicates water entering the tub uncontrolled. Continuing to use the washer risks overflow, water damage to floors and cabinetry, and potential mold growth inside the machine.
Can I reset the code?
Yes. Unplug the washer for 60 seconds to reset the control. However, if the underlying leak or sensor fault is not fixed, E23 will return. Turning off the water supply before resetting is strongly advised.
When to stop immediately?
Stop if you notice: Water is visible on the floor under or around the washer, The tub contains standing water after sitting idle overnight.
Symptoms You May Notice
E23 displays while washer is idle or between cycles
The error appears without a cycle running, because the board continuously monitors the water level even when the machine is at rest and detected unintended water accumulation.
Washer pumps out water immediately after powering on
As soon as you press Power, the drain pump activates to remove water that should not be present. You can hear the pump running before any cycle begins.
Musty odor from the drum
Standing water sitting in the tub between uses can lead to mold and mildew growth inside the drum and door gasket, producing a persistent musty smell.
Wet floor or moisture under the washer
A leaking inlet valve that allows water to seep in continuously can eventually overflow the tub and pool beneath the machine.
Possible Causes
Leaking water inlet valve
A valve that does not fully close when power is removed lets water trickle into the tub continuously. Over time this raises the water level until the flood-protection sensor trips.
Requires ProfessionalFaulty water level pressure sensor
If the pressure switch sends an incorrect "high water" signal to the control board, E23 will trigger even when the tub is actually empty.
Requires ProfessionalBlocked or pinched pressure switch hose
The small rubber hose connecting the tub to the pressure sensor can become kinked or clogged with detergent residue, causing false high-water readings.
DIY PossibleSafe Checks You Can Do
-
1
Turn off the water supply
As a safety precaution, turn off both hot and cold supply valves behind the washer. This stops any water that may be leaking past a faulty inlet valve.
Leave the supply valves closed until the fault is diagnosed — running the washer with an uncontrolled fill leak risks water damage.
-
2
Check the tub for standing water
Open the door and look inside the drum. If water is present when no cycle has been run, the inlet valve is almost certainly leaking and needs replacement.
Even a small amount of water — just an inch — in an idle washer confirms an inlet valve leak.
-
3
Run a drain/spin cycle
If the tub is empty and you believe the fault is a sensor false alarm, turn the supply valves back on, press Power, select Drain & Spin, and press Start. Observe whether E23 clears after the pump runs.
If E23 returns immediately on the next idle period, the sensor or valve requires professional diagnosis.
When to Call a Professional
Contact a qualified technician if:
- Water is found in the idle tub — the inlet valve solenoid needs replacement
- Tub is dry but E23 persists — the pressure sensor or its connecting hose requires inspection
