Fujimak Commercial Dishwasher Fault Codes — What They Mean
Fujimak is a Japanese commercial foodservice equipment brand whose dishwashers are common in Japanese and Asian fusion restaurants, hotel operations, and institutional kitchens across Asia and increasingly the US.
| Code | Meaning | Urgency |

| E2 | Drain fault | Medium |
| E3 | Wash temperature below setpoint | Medium |

| E6 | Booster heater fault | Medium |
| E8 | Door interlock fault | Medium |
Most Common Fujimak Fixes
E1 (water level/fill): Verify water supply valve is fully open. Check supply pressure (minimum 0.5 bar). Clean the water inlet valve filter. If the unit has a rinse water softener, verify it’s regenerating correctly.
E3/E4 (temperature): Fujimak machines require 60°C (140°F) wash and 82-85°C (180-185°F) rinse. Check the booster heater element continuity. On models with steam injection, verify steam supply. Low incoming water temperature extends heat-up time and causes E3/E4.
E5 (wash pump): Check for glass fragments or debris in the pump sump filter (clean it every day). Test pump motor. Fujimak pumps are reliable but debris is the most common cause of pump failure.
