What the code means

communication fault between the main board and display board

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

01Ed is shown on the Midea dishwasher display, indicator, or connected app
02The published condition is: communication fault between the main board and display board
03The appliance has reached the manufacturer-defined stop or service condition associated with Ed
04The important observation is when Ed 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 fault between the main board and display board
02Ed defines a service boundary; the failed internal part still requires exact-model diagnosis
03Model boundary — apply this interpretation only to Midea WQP12-WU7703Q (MDWEB1403QB-WU) dishwasher covered by the linked official manual

Safe next steps

  1. 1
    Confirm the exact Midea Dishwasher Ed model and displayed code before taking action.
  2. 2
    Keep the appliance in a safe state and use only the external checks named in the official source.
  3. 3
    If the condition remains, stop and arrange qualified service; do not open panels or bypass a safety device.

Step-by-step diagnosis

  1. 1
    Photograph the complete Ed display before changing controls or removing power
  2. 2
    Confirm that the full model number is covered by this scope: Midea WQP12-WU7703Q (MDWEB1403QB-WU) dishwasher covered by the linked official manual
  3. 3
    Confirm that the observed condition matches the published meaning: communication fault between the main board and display board
  4. 4
    Published check — Stop repeated testing, record Ed 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 Ed
  8. 8
    Published check — Give service the Ed 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 Ed

Service-safe actions

  1. 1
    Stop repeated testing, record Ed 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 Ed photo, full model and serial number, when it appeared, and the result of every published external check

Repair planning

Cost for the first check
Ed cost planning: The source-listed safety check is usually €0. €90–€220 is a typical Europe planning range for diagnosis before parts; it is not Midea pricing. Ask for separate diagnosis, parts, labor, and call-out lines on the quote.
Time for the first check
Ed time plan: 5–10 minutes to document and isolate safely; 30–90 minutes is a typical diagnostic visit before any model-specific repair.
🔧Tools
Phone camera for the complete Ed display, Full model and serial number, Power or water isolation access as described by the official procedure
Parts or consumables
Ed parts decision: No component should be ordered from Ed alone. The documented fault area is “communication fault between the main board and display board”; the technician must identify the failed model-specific part and revision.

What not to do

  • Do not open fixed panels, test live circuits, bypass protection, or keep operating the appliance after an urgent stop instruction
  • Do not run an extra test cycle after the source tells you to stop or arrange service for Ed

Preventive maintenance

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