Meiko Commercial Dishwasher Fault Codes — What They Mean
Meiko is a German commercial dishwasher brand known for high-quality flight machines, undercounters, and hood machines used in large hotel and institutional kitchens.
| Code / Display | Meaning | Urgency |
|---|---|---|
| Fault 1 / F1 | Water inlet fault | Medium |
| Fault 2 / F2 | Drain fault | Medium |
| Fault 3 / F3 | Temperature too low (wash) | Medium |

| Fault 8 / F8 | Door interlock fault | Medium |

Common Meiko Fixes
F3/F4 (temperature faults): Verify steam or electric heating system. On steam-heated Meiko machines, check steam supply pressure and steam trap. On electric models, check heating element continuity.
F5 (wash pump fault): Check pump impeller for broken glass or debris. Verify pump motor is drawing correct amperage. Meiko wash pumps are robust but can jam on foreign objects.
F8 (door interlock): Confirm door closes fully and interlock switch activates. Meiko door interlocks are safety critical — do not bypass.
