三洋洗衣機顯示EA1，教你檢查方法，十幾塊錢換個件就能修好 #我愛電器維修

hello friends Today we repair a Sanyo washing machine Its problem is after washing for a while Displayed error code e A1 Now let's take it apart and examine it After we take the washing machine apart now let's take a look first step The first thing to check is this water level sensor The water level sensor is here buckle this down first let's take a look After the water level sensor it has a problem it will show error code EA1 In this case we have to remove this come check it out See if it's the problem When we disassemble, we can see that there are three lines on it. Let's take a photo with our phone first waiting for installation and put it in this order Don't get the order of these three lines wrong Then there is a tube on this Let's pull this pipe out of the way Let's take a look after we take it apart The water level sensor We can simply judge See if he is good or bad we can Put your mouth on this tube first give him some pressure Listen to whether there is a sound of suction inside him. If there is a clicking sound Well, it can be roughly judged that this is not bad. This is just an approximate judgment and can't say 100%. If you want to be more precise We can use a multimeter to see The three lines above This is a mechanical water level sensor This pin corner is a common pin Then the other two wiring is a low water The other one is high water We can blow him a pressure with our mouths Measure the pressure with a multimeter Uh, a test pen to connect this Then another test lead is connected to this pin If you can hear a click inside Then he can turn on to prove the low water level he is normal And then we'll go up and blow him some pressure Measure this foot again See if they can get along if he can also conduct After turn on All three pins are fully turned on. If it can be turned on It proves that the water level sensor is a good one If only these two are connected during the test Then this doesn't work he still has problems Now after I check the water level sensor It is normal to find that the water level is low High water level, if it is not directly connected, it has a resistance value So his question It's the water level sensor. The measurements aren't 100% accurate either. we better be Get a new one and test it this is the best way and this one is new i have put it on This is the broken one that was taken apart Now let's test If it's okay, it's his problem In the case of EA1 The most bad one is actually this kind of water level sensor After replacing it, we are testing it. no problem Look, the countdown is now 8 minutes left Okay, thank you for watching the video today see you next time
