E61 - 富及第 烘干机

中文

含义

E61 故障代码表示干衣机加热器继电器电路出现故障，控制系统无法正常接通加热元件的电源。此代码通常在启动加热循环后几秒钟内触发，当控制板检测到继电器驱动信号与加热器实际状态不一致时报告。干衣机仍可运转但无加热，导致无法烘干衣物。

常见原因

1. 加热器继电器线圈开路或短路，无法吸合或持续吸合。
2. 继电器触点烧结粘连，导致加热器持续通电不受控制。
3. 继电器驱动三极管或 MOSFET 击穿，控制信号无法到达继电器线圈。
4. 加热器本身断路（电热丝烧断）或热熔保险丝熔断，控制板误判为继电器故障。
5. 主控板焊点开裂或继电器插座接触不良，间歇性断连。

自助排查

1. 断开电源，打开机壳找到加热器组件，用万用表电阻档测量电热丝两端通断；若为无穷大则电热丝烧断需更换。
2. 检查串联在加热回路中的热熔保险丝是否熔断（用万用表通断档），若熔断需排查过热原因后更换。
3. 找到加热继电器，在启动烘干程序时用万用表测量继电器线圈两端是否有 12V 或 24V 驱动电压；无电压则主控板驱动电路故障。
4. 用万用表测量继电器常开触点两端在吸合时应导通，断开时应无穷大；若始终导通则触点粘连。
5. 检查主控板上继电器相关焊点是否有环形裂纹，必要时补焊或更换主控板。

English

Meaning

Error code E61 indicates a fault in the dryer’s heater relay circuit — the control board cannot properly engage power to the heating element. This code typically triggers seconds after the heating cycle starts when the board detects a mismatch between the relay drive command and the actual heater state. The dryer may tumble normally but produces no heat, making it unable to dry the load.

Common Causes

1. Heater relay coil open or shorted, preventing the relay from pulling in or staying engaged.
2. Relay contacts welded or stuck together, causing the heater to remain powered uncontrollably.
3. Relay driver transistor or MOSFET failed open, blocking the control signal from reaching the relay coil.
4. Heating element burned open or the thermal fuse blown, causing the control board to misinterpret the open circuit as a relay fault.
5. Cold solder joints on the main board or poor contact in the relay socket causing intermittent disconnection.

Self-Check Steps

1. Disconnect power, open the cabinet to access the heater assembly, and measure continuity across the heating element terminals with a multimeter — infinity indicates a burned-out element requiring replacement.
2. Check the thermal fuse in series with the heating circuit for continuity; if blown, identify and resolve the overheating cause before replacing.
3. Locate the heater relay and, with the drying cycle running, measure for 12V or 24V DC across the relay coil terminals — no voltage indicates a control board drive circuit failure.
4. Test the relay normally-open contacts: they should show continuity when the relay is energized and open (infinite) when de-energized; continuous continuity indicates welded contacts.
5. Inspect solder joints on the main board around the relay driver section for ring cracks; reflow or replace the board as needed.
