Technical Details

Repair Steps:

  1. Verify Rinse Aid Level: Visually inspect the rinse aid reservoir located on the machine. Ensure the level is above the minimum fill line. If it’s translucent, check for air bubbles indicating it’s near empty.
  2. Refill Rinse Aid Reservoir: Carefully open the rinse aid cap and refill the reservoir with the appropriate commercial-grade rinse aid recommended for MEIKO dishwashers. Avoid overfilling. Securely close the cap after refilling.
  3. Prime the Rinse Aid System: After refilling, the system may need priming to remove airlocks. Consult your MEIKO UM, UM+, US operator’s manual for the specific priming procedure. This often involves running a short wash cycle or activating a dedicated priming function if available.
  4. Check for Dispenser Blockages or Damage: If the error persists after refilling and priming, inspect the rinse aid suction line and dispenser nozzle for any clogs, kinks, or visible damage. Ensure the dispenser pump (if accessible) is not obstructed.
  5. Test Dispenser Functionality: Run a test cycle to observe if the rinse aid is being dispensed. If no rinse aid is drawn or dispensed, there might be an issue with the dispenser pump itself, the level sensor, or the control board. In such cases, professional service is recommended.

Common Questions:

Q: What is rinse aid and why is it important for my MEIKO dishwasher?

A: Rinse aid is a specialized chemical designed to reduce the surface tension of water, allowing it to sheet off dishes more effectively during the final rinse cycle. This prevents water spots, streaks, and significantly speeds up drying, ensuring your dishes are ready for immediate use.

Q: How often should I check and refill the rinse aid in my MEIKO UM, UM+, US unit?

A: The frequency depends on your machine’s usage volume. For high-volume operations, it’s advisable to check the rinse aid level daily. For moderate use, a weekly check should suffice. Always keep an eye on the error code display as your primary indicator.

Q: I’ve refilled the rinse aid and primed the system, but error code 50 still appears. What should I do next?

A: If the error persists after refilling and priming, there might be a more underlying issue. This could include a faulty rinse aid level sensor, a clogged or damaged dispenser pump, or an electrical issue with the dispenser circuit. It’s recommended to contact a qualified RestoFixer technician for diagnosis and repair.
