TLDR

On your UM, UM+, US unit, error code 965 signifies an Audio-Codec access fault, indicating a communication issue with the sound processing component on the control board. Often, a simple power cycle can resolve transient communication errors. If the issue persists, further diagnostics on the main control PCB or display unit are required.

Technical Details

Repair Steps:

  1. Perform a System Reset (Power Cycle):
    • Locate the main power switch for the MEIKO dishwasher and turn off the power supply completely.
    • Wait for at least 5 minutes to allow all residual power to dissipate and control systems to fully reset.
    • Turn the power back on. Observe if the error code 965 reappears on the display.
    • If the error clears, operate the machine through a wash cycle to confirm stable function.
  2. Inspect Control Board and Display Connections:
    • CAUTION: Always disconnect power to the machine before opening any panels.
    • Access the control panel and main control PCB enclosure. Refer to your MEIKO UM, UM+, US service manual for specific panel removal instructions.
    • Carefully check all wiring harnesses and connectors leading to and from the main control PCB, display module, and any auxiliary audio components.
    • Look for any loose, corroded, or damaged connections. Gently re-seat all relevant connectors.
    • Inspect the control PCB itself for any visible signs of damage, such as burnt components, bulging capacitors, or liquid ingress.
  3. Check for Software/Firmware Issues:
    • While less common for an “access fault,” outdated or corrupted firmware can sometimes lead to communication issues with integrated components like an audio codec.
    • Consult your MEIKO service manual or contact MEIKO technical support to inquire if there’s a relevant firmware update available for your specific UM, UM+, US model. Firmware updates should only be performed by qualified technicians.
  4. Advanced Diagnosis: Main Control PCB or Display Module Fault:
    • If the error persists after checking connections and power cycling, the fault likely lies within the main control PCB or the display module itself. The audio codec is typically integrated into one of these boards.
    • A qualified technician with MEIKO diagnostic tools can test the specific outputs and communication lines.
    • Replacement of the Main Control PCB or the Display Module may be necessary if internal component failure is confirmed. This should only be performed by an authorized service agent.

Common Questions:

Q: What does “Audio-Codec access fault” specifically mean on a MEIKO dishwasher?

A: This error indicates a problem with the machine’s control system attempting to communicate with or utilize the integrated audio codec. This component is responsible for generating sounds, beeps, or voice prompts from the machine. An access fault suggests a failure in communication, power, or the codec chip itself.

Q: Can I continue using my MEIKO UM, UM+, US dishwasher with error 965 displayed?

A: While the primary washing functions may still operate, it is generally not recommended to continue prolonged use with an active error code. An audio-codec access fault, though seemingly minor, could be a symptom of a deeper issue with the control board that might lead to more critical failures down the line. It’s best to address it promptly.

Q: Is replacing a part expensive for this type of fault?

A: The cost largely depends on which component is faulty. If it’s a loose connection, the repair is minimal. However, if the main control PCB or display module requires replacement, these are significant components and can be expensive, often necessitating professional service for diagnosis and installation.

When to call a technician

Consider calling a certified technician if:

  • The error keeps coming back after you've tried the steps above.
  • You're not comfortable doing the checks or repairs yourself.
  • You notice unusual noise, smell, or behaviour.
  • Equipment is under warranty and you want official service.
  • You need the unit back in service quickly with minimal downtime.
