What the code means

communication failure between the main PCB and motor-inverter PCB

Isolate the appliance when safe. Stop repeated testing, record E64 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

01E64 is shown on the Midea washing machine display, indicator, or connected app

02The published condition is: communication failure between the main PCB and motor-inverter PCB

03The affected motor, drive, or movement function is stopped or limited while E64 is active

04The important observation is when E64 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 — communication failure between the main PCB and motor-inverter PCB

02E64 identifies a drive condition but does not alone prove the motor, inverter, belt, bearing, rotor, wiring, or control failed

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
Confirm the exact Midea Washing machine E64 model and displayed code before taking action.
2
Keep the appliance in a safe state and use only the external checks named in the official source.
3
If the condition remains, stop and arrange qualified service; do not open panels or bypass a safety device.

Step-by-step diagnosis

1
Photograph the complete E64 display before changing controls or removing power
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
Confirm that the observed condition matches the published meaning: communication failure between the main PCB and motor-inverter PCB
4
Published check — Stop repeated testing, record E64 and the full model number, and arrange Midea service
5
Published check — do not open fixed panels or test live circuits
6
Stop at the published service boundary after these actions
7
do not add a restart or test cycle that Midea does not specify for E64
8
Published check — Give service the E64 photo, full model and serial number, when it appeared, and the result of every published external check
9
Stop at the published service boundary after these actions; do not add a restart or test cycle that Midea does not specify for E64

Service-safe actions

1
Stop repeated testing, record E64 and the full model number, and arrange Midea service
2
do not open fixed panels or test live circuits
3
Give service the E64 photo, full model and serial number, when it appeared, and the result of every published external check

Repair planning

€Cost for the first check
E64 cost planning: The published load, obstruction, or restart check costs €0. A drive-system diagnosis is generally planned within €90–€220 before parts, with the component and labor quoted separately.

⏱Time for the first check
E64 time plan: 10–20 minutes for the permitted E64 external checks and one controlled test; professional drive diagnosis commonly takes 45–90 minutes.

🔧Tools
Phone photo of E64, Full model and serial number, Flashlight for an external stopped-appliance inspection only, No live motor or inverter test equipment

▣Parts or consumables
E64 parts decision: E64 identifies communication failure between the main PCB and motor-inverter PCB. It does not alone confirm a motor, inverter, belt, bearing, rotor, wiring harness, or control board; the exact failed item must be diagnosed on the listed model family.

What not to do

Wait for all movement to stop
Do not rotate a powered mechanism, bypass an interlock, test inverter output, or order a motor from E64 alone
Do not run an extra test cycle after the source tells you to stop or arrange service for E64

Preventive maintenance

1
Follow the exact Midea maintenance schedule for the washing machine and keep the model, serial number, and service history available
2
If E64 begins recurring despite the documented maintenance, stop repeating the same action and request exact-model diagnosis

Frequently asked questions

What exactly does E64 identify?

Midea identifies it as communication failure between the main PCB and motor-inverter PCB.

Which action is actually supported for E64?

Stop repeated testing, record E64 and the full model number, and arrange Midea service; do not open fixed panels or test live circuits; Give service the E64 photo, full model and serial number, when it appeared, and the result of every published external check.

Can I run another test after E64?

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

Does E64 prove which part failed?

No. It identifies “communication failure between the main PCB and motor-inverter PCB”; parts are selected only after the exact model and failed function are confirmed.

What information should accompany a service request?

The E64 photo, full model and serial number, the operating stage when it appeared, and the result of each published check.
