i60 - 富及第 洗碗机

中文

含义

错误代码 i60 表示洗碗机加热系统故障，洗涤水温未能在规定时间内达到目标温度。控制器在加热阶段通过 NTC 温度传感器监控水温上升速率，若在一定时间内温升不足或温度偏离设定值过大，则判定为加热故障并中止程序。

加热管烧断、继电器触点烧结或温度传感器信号异常都可能导致此故障。

常见原因

1. 加热管烧断（开路） — 加热元件长期使用后内部电阻丝熔断，无法产生热量。万用表测量阻值为无穷大。
2. 加热控制继电器故障 — 继电器触点烧结无法释放（持续加热）或线圈开路（不加热）。
3. 加热管表面水垢过厚 — 硬水地区长期使用后加热管表面包裹厚厚的水垢层，热量无法有效传递给水体。
4. NTC 温度传感器信号偏移 — 传感器阻值漂移导致控制器读取到错误的温度值，误判加热不足或加热过度。
5. 加热管对地漏电 — 绝缘层破损导致加热管漏电至机壳，线路保护装置（漏电保护器或保险丝）切断加热电路。

自助排查

1. 观察运行中机器是否能正常出热水。若全程冷水，重点怀疑加热管或继电器故障。
2. 断开电源，拆下加热管接线端子，用万用表电阻档测量加热管两端阻值 — 正常应为 10-100 Ω（视功率而定）。阻值为 OL 表示开路损坏。
3. 用万用表测量加热管对地（金属外壳）绝缘电阻，正常应大于 1 MΩ。若阻值很小或导通，说明绝缘损坏需更换。
4. 目视检查加热管表面水垢情况。若水垢层过厚，可使用专业洗碗机除垢剂进行循环清洗除垢。
5. 如果加热管阻值正常且绝缘良好但故障依旧，可能为控制板继电器或线路故障，建议联系专业维修人员。

English

Meaning

Error code i60 indicates a heating system failure — the wash water did not reach the target temperature within the allowed time. The control board monitors the temperature rise rate via the NTC thermistor during the heating phase; if the rate is too slow or the temperature deviates excessively, the system declares a heater fault and aborts.

A burnt-open heating element, a stuck relay, or a drifting temperature sensor can all trigger i60.

Common Causes

1. Open heating element — the internal resistance wire has melted through after extended use. The element shows OL (infinite resistance) on a multimeter.
2. Defective heating relay — relay contacts are welded shut (continuous heating) or the coil is open (no heating at all).
3. Heavy scale buildup on the heating element — in hard-water areas, thick calcium deposits insulate the element, preventing efficient heat transfer to the water.
4. Drifting NTC temperature sensor — the sensor’s resistance curve has shifted so the control board reads an incorrect temperature, leading to under- or over-heating.
5. Heating element ground leakage — cracked insulation causes current leakage to ground, tripping the GFCI or blowing the thermal fuse that feeds the heater circuit.

Self-Check Steps

1. Run a short cycle and feel the water temperature mid-cycle. If the water remains cold throughout, the heater or its control relay is likely faulty.
2. Disconnect power, remove the heating element terminals, and measure resistance across the element with a multimeter — normal range is 10-100 Ω depending on wattage. OL indicates an open element.
3. Measure insulation resistance between each terminal and the element’s metal sheath (ground). A healthy reading exceeds 1 MΩ. Low or zero resistance means the insulation is compromised.
4. Visually inspect the element for heavy scale deposits. If heavily calcified, run a dishwasher descaler cycle to remove buildup.
5. If the element measures correctly but the error persists, the control relay or main board circuitry may be at fault — contact a qualified technician.
