Universal Washing Machine Drainage Error Code: Step-by-Step Fix
Required Tools for this Fix
- Pliers
- Bucket
- Screwdriver
Quick Summary Answer: A universal washing machine drainage error code (such as OE, 5E, F9E1, or E18) indicates that your washer failed to evacuate water within the control board’s allotted time limit. This issue is usually caused by a clogged coin trap filter, a kinked drain hose, or a debris-bound drain pump impeller. You can usually clear this error in under 30 minutes by cleaning out the filter trap, checking the outlet hose, and resetting power to the machine.
WARNING: RISK OF ELECTRIC SHOCK AND WATER DAMAGE
Always disconnect the washing machine from electrical power by unplugging the unit or switching off the dedicated circuit breaker before removing any panels, filters, or electrical components. Working with standing water near electrical assemblies poses a severe shock hazard. Keep plenty of towels, a shallow baking pan, and a shop vacuum nearby to manage spillage.
Universal Drainage Error Diagnostic Overview
When your washing machine stops mid-cycle and leaves a tub full of soapy water, the main control board triggers a drainage error code. Different manufacturers use different alphanumeric combinations to flag this exact issue.
Samsung uses 5E or 5C, LG displays OE, Whirlpool and Maytag show F9E1 or LD, GE uses E22, and Bosch triggers E18. Despite the different labels, all these codes signal that the machine could not lower the internal water level within a set timeframe.
We designed this practical guide to help you diagnose and fix any brand of washing machine that refuses to drain water. Follow our step-by-step technical instructions below to isolate the fault and save money on a service call.

How the Washer Drainage System Works
Understanding how water leaves your machine makes troubleshooting much easier. The drainage sequence begins when the main control board finishes a wash or rinse phase and sends 120 volts of electricity to the drain pump motor.
The drain pump motor spins a plastic impeller at high speed, creating a centrifugal force that pulls water out of the tub through the sump hose. Water passes through a filter or coin trap, travels through the pump housing, and exits through the corrugated drain hose into your home standpipe.
While water evacuates, a pressure sensor (or water level switch) monitors internal air pressure through an air tube attached to the outer tub. Once water drops back down to the empty baseline level, the sensor sends a signal to the control board to start the spin cycle. If water remains in the tub after 10 to 15 minutes, the control board halts operation and throws a drainage error code.
Step-by-Step Diagnostic Checklist
Follow this quick diagnostic sequence in order to isolate the root cause without buying unnecessary parts:
- Power Check: Unplug the unit before starting physical diagnostics.
- Emergency Drain: Manually remove standing water to prevent flooding during repairs.
- Filter Check: Inspect and clear the coin trap or debris filter.
- Hose Check: Inspect the external drain hose for kinks, crushing, or blockages.
- Standpipe Check: Confirm the household drain line is flowing freely.
- Impeller Check: Verify the pump impeller spins freely and is free of debris.
- Electrical Test: Check the drain pump motor windings for electrical continuity using a multimeter.
- Air Line Check: Inspect the pressure switch hose for clogs or soapy sludge buildup.
- System Reset: Clear the error code from the control board memory.
Step 1: Drain Standing Water Safely
Before you can work on internal components, you must remove the water trapped inside the tub. Opening a front-load filter door or removing a bottom panel while the drum is full will cause a flood in your laundry room.
For Front-Loading Washing Machines
Locate the small access door on the bottom front corner of the machine. Inside, you will find a small, flexible emergency drain tube alongside the main filter cap.
Pull out the small rubber tube, place a shallow pan beneath it, and pull off the plastic plug. Allow water to drain into the pan, replacing the plug each time you fill and dump the pan.

For Top-Loading Washing Machines
Top-loading machines generally lack an external emergency drain tube. You can use a small bucket or plastic cup to scoop water out of the drum from above.
Alternatively, use a wet/dry shop vacuum to pull water directly out of the drum or from the end of the drain hose at the wall. Removing as much weight as possible makes moving or tilting the machine safe and easy.
Step 2: Clean the Drain Pump Filter (Coin Trap)
Small items like coins, hairpins, socks, and lint frequently slip past the tub seal and collect in the drain pump filter. This filter protects the pump impeller from damage, but a heavy buildup will completely block water flow.
Accessing and Cleaning Front-Load Filters
Unclip the access panel on the front bottom of your washer. Unscrew the large plastic filter knob counterclockwise while placing a towel directly under the housing to catch residual water.
Pull the filter assembly straight out and peel away any accumulated lint, hair, or debris. Wash the filter screen thoroughly under warm tap water using an old toothbrush.
Look inside the exposed pump cavity with a flashlight to verify no loose coins or buttons are trapped inside the housing. Reinsert the filter cleanly, screwing it firmly clockwise to prevent future leaks.

Accessing Top-Load Pump Housings
Most top-load washing machines do not have a front-accessible filter door. Instead, the pump is located beneath the tub or behind the rear access panel.
Disconnect power, turn off the hot and cold water supply valves, and unhook the fill hoses. Tilt the machine back against a wall or lay it gently on its side to access the pump underneath.
Squeeze the wire clamps on the sump hose connecting the tub to the pump using pliers, then slide the hose off. Check the interior of the sump hose for stuck baby socks or foreign objects.
Step 3: Inspect the Drain Hose and Home Standpipe
If the pump filter is clean, the block may be located further down the line in the external drain hose or wall pipe. Corrugated drain hoses kink easily when machines are pushed too far back against the wall.
Inspecting for Kinks and Mechanical Crushing
Pull the washing machine 12 inches away from the back wall. Inspect the entire length of the black or grey corrugated hose for sharp bends, flat spots, or kinks.
Straighten any twisted sections of the hose. If the plastic hose has formed a permanent crease that restricts water flow, replace the hose assembly entirely.
Performing the Bucket Drain Test
Pull the end of the drain hose out of the wall standpipe or laundry sink. direct the end of the hose into a large 5-gallon bucket, holding it securely so it cannot kick back.
Plug the washer in and select a manual “Drain & Spin” cycle. If water pumps out forcefully in a full stream into the bucket, your washing machine is functioning properly.
If water flows strong into the bucket, your household plumbing or standpipe is clogged. You will need to clear your wall pipe using a drain auger or call a licensed plumber.

Step 4: Inspect and Test the Drain Pump Assembly
When the drain pump motor receives power but cannot turn, it often emits a low buzzing or humming sound. This happens when foreign debris jams the impeller, or when the internal motor windings break down electrically.
Physical Impeller Inspection
With the pump filter removed or the pump unbolted from the frame, shine a light into the pump chamber. Locate the plastic impeller, which looks like a small four-blade fan.
Reach inside with needle-nose pliers or your fingers and try to spin the impeller. It should turn with a firm, spring-like resistance (a rhythmic clicking sensation) as it passes internal motor magnets.
If the impeller spins completely freely without resistance, the impeller shaft has snapped away from the motor drive, requiring pump replacement. If the impeller will not turn at all, clear out any threads, hair, or small objects wrapped around the shaft.

Testing the Drain Pump Motor with a Multimeter
If no physical jam exists, test the electrical health of the pump motor coils. Disconnect power to the machine and pull off the two wire harness leads connected to the pump motor terminals.
Set your digital multimeter to the lowest Resistance setting (Rx1 or Ohms $\Omega$). Touch one meter probe to each terminal on the drain pump motor.

A functional drain pump motor will show a resistance reading between 5 and 45 Ohms, depending on the brand and design. If your meter displays an open circuit (OL or infinite resistance), the internal coil wire has burnt out, and you must replace the pump.
Next, touch one probe to a metal terminal and the second probe to the bare metal frame or ground pin of the pump motor. If the meter reads anything other than open circuit (OL), the motor has shorted to ground and must be replaced.
Step 5: Check the Water Level Pressure Switch and Air Tube
Sometimes the washer drains all the water successfully, but the control panel still throws a drainage error code. This happens when the pressure switch system is tricked into thinking the tub is still full.
How the Pressure System Gets Blocked
A thin rubber tube runs from the bottom of the outer drum up to a pressure sensor located near the main control board. As water fills the drum, air traps inside this tube and pushes upward against a diaphragm in the switch.
Over time, liquid detergent scum, fabric softener, and lint can build up at the bottom nipple of this air hose. This traps pressurized air inside the tube even after the pump clears all water from the machine.

Inspecting and Clearing the Pressure Hose
Disconnect power and remove the top or rear panel of your washer to locate the mechanical pressure switch or digital pressure sensor. Carefully disconnect the thin rubber hose from the nipple on the switch.
Blow gently through the rubber hose down toward the tub. You should feel minimal resistance, and you should hear air bubbling out through any tiny residual water at the bottom of the drum.
If the hose feels blocked, pull it off the lower tub connection and flush it with warm tap water to clear out trapped soap scum. Inspect the rubber for pinhole punctures or cracks, as air leaks will also cause false water level readings.
Step 6: Inspect Door Locks and Drive Belts
Certain secondary mechanical failures can halt the drain phase before the pump completes its cycle.
Door Lock Assemblies and Lid Switches
Front-load washers will not enter a high-speed drain or spin cycle if the door latch switch fails to signal that the door is securely locked. Top-load machines use lid switches or strike switches that break circuit continuity if the lid bounces or misaligns.
If your washer refuses to pump water and shows a door lock icon or lid switch code along with the drain error, inspect the latch mechanism. Replace broken plastic door catches or worn electrical door lock assemblies.
Belt Condition on Top-Load Washing Machines
Some older top-load washing machines use a single drive motor to turn both the transmission impeller and a mechanical drain pump via a rubber belt.
If this drive belt slips, stretches, or breaks, the pump will not spin fast enough to clear water before the timer runs out. Inspect the belt under the unit for cracking, burning, or loose tension, and replace it if worn.
Step 7: How to Replace a Failed Drain Pump Motor
If your diagnostic tests point to a dead or mechanically broken drain pump motor, replacing it is a straightforward DIY repair.
Parts Removal and Installation Sequence
- Disconnect the main power plug and shut off all water supply lines.
- Manually drain all residual water using the methods outlined in Step 1.
- Access the drain pump by removing either the front lower panel, rear access cover, or bottom base plate.
- Unplug the plastic wire harness connector from the pump motor terminals.
- Use spring pliers to slide back the hose clamps securing the inlet and outlet hoses to the pump body.
- Twist and pull the rubber hoses off the pump ports.
- Unbolt the mounting screws securing the pump frame to the washer chassis.
- Lift out the old pump assembly and set the replacement pump in place.
- Tighten the mounting screws, reattach the rubber hoses, and secure the wire clamps tightly over the hose barbs.
- Reconnect the electrical wiring harness, reassemble the cabinet panels, and plug the unit back into power.
How to Clear and Reset the Error Code
Once you have identified and fixed the mechanical or electrical fault, you may need to clear the saved error code from the washer memory.
Soft Reset Procedure
- Press the Power button to turn the washing machine off.
- Unplug the main power cord from the wall outlet for a full 5 minutes.
- While the unit is unplugged, press and hold the Power/Start button for 5 seconds to discharge residual capacitor energy from the control board.
- Plug the washer back into the wall outlet.
- Open and close the washer door or lid 6 times within 12 seconds to send a reset signal to the board.
- Run a brief “Drain & Spin” cycle to confirm the error code is cleared and the machine runs properly.
Preventative Maintenance Practices
Taking a few basic maintenance steps will keep your drain system working smoothly and prevent future drainage errors:
Use Proper HE Detergent Dosages
Excessive laundry detergent creates heavy suds that cushion water movement and trap air in the pressure switch tube. High-efficiency (HE) washers require low-foaming detergent; use no more than 2 tablespoons of liquid detergent per standard load.
Protect the Pump with Laundry Mesh Bags
Small items like baby socks, thin thongs, coin pockets, and brassier underwires are the main causes of jammed drain pumps. Always wash delicate or tiny clothing items inside zippered mesh laundry bags to stop them from sliding into the outer tub sump line.

Regular Cleanout Routines
Clean your front-load pump filter every 3 to 6 months to remove hair and sediment build-up. Run a monthly tub clean cycle using hot water and a dedicated washer cleaner tablet or citric acid powder to dissolve soap scum deposits throughout the pump lines.
Frequently Asked Questions
Why is my washer making a loud humming or grinding noise during the drain cycle?
A humming or grinding noise almost always points to a mechanical obstruction inside the drain pump housing. A coin, button, or small screw has likely passed into the pump chamber and is striking the plastic impeller blades as they spin. If you do not clear the object quickly, it will chip the blades or burn out the pump motor.
Can a bad lid switch or door latch trigger a drainage error?
Yes. Many modern washing machines will not run the drain pump or begin the spin cycle if the main control board cannot verify that the door or lid is fully closed and locked. If the door lock mechanism fails electrically, the board may time out and throw a drainage or door lock error code.
How much standing water is normally left under the tub after a cycle?
It is normal for a small amount of water—typically between 1 to 2 cups—to remain in the bottom of the pump housing and sump hose after a completed cycle. This residual water seals the check valve and prevents foul sewer gas smells from coming up through your household plumbing into the washer drum.
What should I do if my washer drains slowly but doesn’t throw an error code yet?
Slow draining is an early warning sign that a complete blockage is forming in your drain filter, hose, or standpipe. Clear your front-access coin trap filter immediately and check the external hose for kinks before the system clogs completely and stops working mid-cycle.
How do I know if the drain pump or the main control board is bad?
Test the drain pump terminals for 120V AC electrical power using a multimeter while the washer is running a manual drain cycle. If the pump receives 120 volts from the board but refuses to run or hum, the pump motor is bad. If the pump never receives voltage from the board during the drain cycle, the control board relay or wiring harness has failed.
Safety Precaution Notice
Before proceeding with any repair checklist: Always unplug the appliance from its electrical socket and turn off shutoff valves for incoming water (for washers and dishwashers). Discharge capacitors if working on motors.
