Technical Details

Repair Steps:

  1. Verify Wash Arm Presence and Installation: Open the dishwasher door and visually confirm that both the upper and lower wash arms are present. Ensure they are securely clipped into their respective positions and not loose or dislodged. Refer to Section 5.1 of your MEIKO UM, UM+, US operating manual for correct installation procedures during daily cleaning.
  2. Check for Blockages: Manually rotate each wash arm to ensure it spins freely without obstruction. Inspect all spray nozzles on both arms for any food debris, scale, or foreign objects that might be blocking them. Use a small brush or toothpick to clear any visible blockages.
  3. Inspect for Damage: Examine the wash arms for any cracks, breaks, or warping, especially around the mounting points or nozzles. A damaged arm may not distribute water correctly, even if present. Replace any compromised wash arms promptly.
  4. Clean Wash Arm Filter/Inlet: Some MEIKO models have a small filter screen or inlet where the wash arm connects. Remove the wash arm and check this connection point for any accumulated debris that might restrict water flow to the arm. Clean as necessary.
  5. Reinstall and Test: After inspection and cleaning, carefully reattach both wash arms, ensuring they click into place securely. Close the door and run a short test cycle with no dishes to observe water distribution and confirm the error code clears.

Common Questions:

Q: What are the common symptoms of a wash arm problem on my MEIKO UM, UM+, US?

A: Beyond error code 116, you might notice dishes are not getting clean, especially in certain areas of the rack, or water pressure inside the wash chamber appears weak or uneven. The wash arms might also not rotate freely.

Q: How often should I inspect my MEIKO wash arms?

A: It is recommended to inspect and clean your MEIKO UM, UM+, US wash arms daily as part of your routine cleaning procedures (refer to Section 5.1 of your manual). This prevents debris buildup and ensures optimal washing performance.

Q: Can I run my MEIKO UM, UM+, US if error 116 persists?

A: While the machine might technically run, operating it with wash arms missing or blocked will result in very poor wash quality and could potentially waste water and energy. It is strongly advised to resolve error 116 before regular operation to ensure proper sanitation and efficient operation.
