回答1:

很好判断,只要出现以下几种情况就说明水位传感器是坏的:

1、漏气:这种很好判断,吹一下就知道;

2、线圈断了:可以使用万用表测量;

3、线圈有短路:这种情况很少,不好判断;

4、电容漏电,短路,容量减少:这种情况经常发生,两脚的传感器不好测量,三脚的就容易得多。好的传感器接入电路就能够测量到特定频率,漏气的也可以,其它故障的传感器通常会主板报警,灯闪,频率变为工频50HZ或者直接停震。

扩展资料:

全自动洗衣机水位控制主要通过水压控制水位开关来实现,该部位发生故障时就会出现类似现象。出现此类故障可能有以下几种原因:一是电脑板损坏,不能识别水位开关信号;二是水位控制开关不良;三是水压传导皮管破裂或漏气。

判别电脑板好坏的方法比较简单,只需断接两根水位开关信号线即可,洗衣机如能进行正常进水,说明电脑板是好的。也可能是隐蔽故障所致,如拆开洗衣机会发现洗衣机外桶壁上附着很多纤维杂物,或将水位检测孔堵塞,清除干净后故障即能排除。

出现这一故障的洗衣机一般使用年限较长,所以最好能从内部彻底清洗一下根除隐患。

1、检查前首先确认洗衣机盛水桶里没有残留水、导气管有无扭结或堵塞的现象。

因为如果盛水桶有水或者导气管管路不畅,则都可能使储气室内气压过高或过低,造成水位传感器反馈信息输出错误导致不进水或进水不止。如有以上故障排除后,再进行进水试机,若还是不能进水或进水不止,则可能是水位传感器故障所致。

2、电磁式水位传感器(水位传感器):若水位传感器线圈损坏,电脑板会检测到水位传感器异常停止进水并报警。即开机启动就就报警(显示E4),不进水;此故障是水位传感器坏,更换水位传感器即可解决。

3、触点式水位传感器(水位开关):在断电状态下,用万能表测水位开关两接线端子之间的电阻,如若是电阻很小,则说明开关触点未断开,可能是防伪弹簧断裂或失去弹性,或者是公共触点与常开触点卡死,此时因更换水位开关。

水位传感器是指能将被测点水位参量实时地转变为相应电量信号的仪器。其工作原理是:

容器内的水位传感器,将感受到的水位信号传送到控制器,控制器内的计算机将实测的水位信号与设定信号进行比较,得出偏差,然后根据偏差的性质,向给水电动阀发出"开"和"关"的指令,保证容器达到设定水位。

进水程序完成后,温控部份的计算机向供给热媒的电动阀发出"开"的指令,于是系统开始对容器内的水进行加热。到设定温度时。控制器才发出关阀的命令、切断热源,系统进入保温状态。

程序编制过程中,确保系统在没有达到安全水位的情况下,控制热源的电动调节阀不开阀,从而避免了热量的损失与事故的发生。

广泛用于水厂、炼油厂、化工厂、玻璃厂、污水处理厂、高楼供水系统、水库、河道、海洋等对供水池、配水池、水处理池、水井、水罐、水箱、油井、油罐、油池及对各种液体静态、动态液位的测量和控制。
