What the code means

water level does not change within the published drain interval

Follow the exact model manual. Stop repeated testing, record E21 and the full model number, and arrange Midea service; do not open fixed panels or test live circuits. Do not open fixed panels or test live circuits.

Typical symptoms

01E21 is shown on the Midea washing machine display, indicator, or connected app
02The published condition is: water level does not change within the published drain interval
03Water or condensate does not leave through the documented drain path as expected while E21 is active
04The important observation is when E21 appears and whether the exact published action changes that condition

Fault area and what the code does not prove

Separate the manufacturer-defined condition from components that still need exact-model diagnosis.

01Manufacturer-defined fault area — water level does not change within the published drain interval
02E21 does not distinguish an accessible restriction, hose installation, household drain, pump, wiring, or control until the drain path is checked
03Model boundary — apply this interpretation only to Midea MF110W80BA10-W, MF110W90BA10-W and MF110W100BA10-W washing-machine series covered by the linked official service manual

Safe next steps

  1. 1
    Confirm the exact Midea Washing machine E21 model and displayed code before changing settings.
  2. 2
    Complete only the user-accessible checks described in the linked official source.
  3. 3
    Run one controlled test after the check; if the code returns, stop and use the model manual or qualified service.

Step-by-step diagnosis

  1. 1
    Photograph the complete E21 display before changing controls or removing power
  2. 2
    Confirm that the full model number is covered by this scope: Midea MF110W80BA10-W, MF110W90BA10-W and MF110W100BA10-W washing-machine series covered by the linked official service manual
  3. 3
    Confirm that the observed condition matches the published meaning: water level does not change within the published drain interval
  4. 4
    Published check — Stop repeated testing, record E21 and the full model number, and arrange Midea service
  5. 5
    Published check — do not open fixed panels or test live circuits
  6. 6
    Stop at the published service boundary after these actions
  7. 7
    do not add a restart or test cycle that Midea does not specify for E21
  8. 8
    Published check — Give service the E21 photo, full model and serial number, when it appeared, and the result of every published external check
  9. 9
    Stop at the published service boundary after these actions; do not add a restart or test cycle that Midea does not specify for E21

Evidence-backed actions

  1. 1
    Stop repeated testing, record E21 and the full model number, and arrange Midea service
  2. 2
    do not open fixed panels or test live circuits
  3. 3
    Give service the E21 photo, full model and serial number, when it appeared, and the result of every published external check

Repair planning

Cost for the first check
E21 cost planning: €0 for an accessible blockage check; typically €10–€45 for a confirmed hose, cap, or seal. A diagnosed pump repair commonly moves into the €90–€220 service range before parts.
Time for the first check
E21 time plan: 15–35 minutes to drain safely, inspect accessible points, refit them, and run one short drain test.
🔧Tools
Dry towels, shallow tray, and household gloves, Flashlight, A coin or hand grip only if the exact-model manual permits opening the user-accessible filter cover
Parts or consumables
E21 parts decision: Usually none for clearing an accessible filter or hose. A drain pump is not confirmed by E21; match any pump, cover, seal, or hose to the full model only after diagnosis.

What not to do

  • Do not force a jammed pump cover, tip an appliance containing water, or reach into the pump area while power is connected
  • Do not run an extra test cycle after the source tells you to stop or arrange service for E21

Preventive maintenance

  • 1
    Keep user-accessible filters, seals, hoses, and drain connections clean and inspect them periodically for damage or seepage
  • 2
    If E21 begins recurring despite the documented maintenance, stop repeating the same action and request exact-model diagnosis

Frequently asked questions

What exactly does E21 identify?

Midea identifies it as water level does not change within the published drain interval.

Which action is actually supported for E21?

Stop repeated testing, record E21 and the full model number, and arrange Midea service; do not open fixed panels or test live circuits; Give service the E21 photo, full model and serial number, when it appeared, and the result of every published external check.

Can I run another test after E21?

Not unless the official procedure above explicitly includes it. Complete the safe external actions, then keep the appliance stopped at the service boundary.

Does E21 prove which part failed?

No. It identifies “water level does not change within the published drain interval”; parts are selected only after the exact model and failed function are confirmed.

What information should accompany a service request?

The E21 photo, full model and serial number, the operating stage when it appeared, and the result of each published check.
