Midea E21 on washing machine: drain timeout emptying drum
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
E21 on Midea front-loading washing machines means water draining exceeded the time limit because the drum water level did not change within 6 minutes. Check that the drain hose is not kinked or hung above 1 m, let the water cool, and clean the pump filter before calling service.
Safety first
Stop and check this first
- Always wait for the water inside the drum to cool down and unplug the washing machine before opening the emergency drain hose or pump filter to avoid scalding and electric shock.
- Never pull the emergency door release cord while the washer is running or filled with hot water, and always refit the emergency drain hose plug securely to prevent water leaks.
Safe checks you can perform
- Inspect the drain hose routing and installation height
- Drain cooled water via the emergency hose and clean the pump filter
- Run a spin-only test cycle to verify water evacuation
- Technician check of internal hose, drain pump and level sensor
Leave these tasks to a qualified professional
- Do not attempt this professional task: Remove the internal pump hose and clear trapped articles
- Do not attempt this professional task: Test drain pump resistance (150-250 ohms) and replace if faulty
- Do not attempt this professional task: Inspect the water level sensor (10-50 ohms) and PCB wiring harness
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Remove the internal pump hose and clear trapped articles
What they doThe technician disconnects power, detaches the hose from the drain pump housing, and inspects both the hose and pump chamber for small socks or foreign objects before replacing any part.
They must show youany obstruction removed from the internal hose or pump housing and a full drain test.
In writingcode E21, the internal drain path cleaning performed, and leak-free reassembly.
Test drain pump resistance (150-250 ohms) and replace if faulty
What they doThe technician safely tilts the machine, unplugs the drain pump connector, measures coil resistance with a multimeter (150 to 250 ohms is normal), and replaces the drain pump if out of range.
They must show youthe multimeter reading on the old drain pump and normal water discharge with the replacement unit.
In writingmeasured drain pump resistance in ohms, replacement part number if fitted, and test result.
Inspect the water level sensor (10-50 ohms) and PCB wiring harness
What they doWith the tap closed and the top cover removed via its 2 rear screws, the technician checks the water level sensor connector, measures sensor resistance (10-50 ohms), and verifies harness continuity to the PCB.
They must show youthe 10-50 ohm measurement on the water level sensor and the condition of its terminal connector.
In writingmeasured water level sensor resistance, harness inspection findings, and any part replaced.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Inspect the drain hose routing and installation height
- Who:
- you.
- How:
- check behind the Midea washing machine to make sure the drain hose is not kinked or crushed and that the hose end is not hung higher than 1 m (100 cm) above the floor.
- Result that matters:
- ruling out a pinched hose or excessive drain height that stops water from leaving the tub.
- If the hose was bent or hung above 100 cm:
- straighten it, set the height within the installation limit, and test a spin-only cycle.
- If the hose runs freely at the proper height but water remains inside:
- proceed to draining and cleaning the pump filter.
- Evidence to keep:
- a photo of the rear drain hose routing and the height of the drain connection.

Drain cooled water via the emergency hose and clean the pump filter
- Who:
- you.
- How:
- wait until the water cools, switch off and unplug the washer, open the lower service flap, pull out the emergency drain hose and remove its cap to empty the tub, then turn the pump filter counter-clockwise to remove debris.
- Result that matters:
- clearing trapped lint, coins, or small items from the drain filter and refitting both the cap and filter clockwise.
- If foreign matter comes out of the filter housing:
- clean the filter, screw it back in clockwise, refit the emergency hose cap, and test.
- If the filter is clean yet E21 returns after 6 minutes of draining:
- leave internal pump disassembly to an authorized technician.
- Evidence to keep:
- any debris removed from the pump filter and confirmation that the emergency hose cap is sealed.

Run a spin-only test cycle to verify water evacuation
- Who:
- you.
- How:
- once the drain filter and emergency hose plug are securely refitted, plug the Midea washer back in, turn it on, and select the spin-only program to drain any residual water.
- Result that matters:
- verifying whether the drum empties within the 6-minute threshold without triggering E21.
- If the machine drains normally and completes the cycle:
- clean the drain pump filter every 1 to 3 months as preventive maintenance.
- If water still does not drain and E21 reappears:
- unplug the appliance, close the water tap, and contact authorized service.
- Evidence to keep:
- whether the drain pump hums during the spin-only test and whether the water level drops.

Technician check of internal hose, drain pump and level sensor
- Who:
- authorized service technician with mains power disconnected.
- How:
- remove the hose from the pump body to check for trapped clothing, inspect wiring connectors, and measure the drain pump resistance (150-250 ohms) and water level sensor resistance (10-50 ohms).
- Result that matters:
- pinpointing whether E21 is caused by an internal hose blockage, a failed pump coil, or a faulty level sensor.
- If pump resistance is outside 150-250 ohms or level sensor resistance is outside 10-50 ohms:
- replace the faulty component with a genuine part.
- If pump, sensor, and harness test within specification:
- replace the main PCB and verify draining in service mode.
- Evidence to keep:
- multimeter ohm readings for both the drain pump and the water level sensor.
Tilting the washer or removing the top cover exposes 220-240 V internal wiring: authorized technician only with power unplugged.

What it means
In Midea front-loading washing machine service documentation, malfunction code E21 indicates overtime water draining triggered when the water level inside the drum does not change within 6 minutes. Common causes include a kinked drain hose behind the cabinet, a drain outlet hung above 100 cm, or foreign matter and small garments trapped in the drain pump filter. Seeing E21 on the display does not by itself prove that the drain pump or PCB is defective.

Symptoms and causes
Probable causes · in order
- Drain pump filter or hose blocked by lint, coins or small socksCommon
Foreign objects such as coins, buttons, or a small sock caught in the drain pump filter or hose prevent water from leaving the tub within the 6-minute window.
Evidence: Midea front-loading washing machine technical service manual L11 · Midea MF200D80WB series manual de usuario de lavadora-secadora
- Drain hose kinked behind the washer or hung above 1 mCommon
A pinched drain hose behind the machine or a standpipe connection higher than 1 m (100 cm) restricts outflow enough to trigger code E21.
Evidence: Midea front-loading washing machine technical service manual L11
- Defective drain pump motor or loose pump wiring connectorPossible
An unplugged harness or a drain pump coil outside the normal 150 to 250 ohm resistance range stops the pump from emptying the drum.
Evidence: Midea front-loading washing machine technical service manual L11
- Out-of-range water level sensor or main PCB faultLess common
If the water level sensor resistance drifts outside 10 to 50 ohms or its wiring to the main board fails, the controller cannot register the drop in water level.
