How to Diagnose a Faulty Washing Machine Heater


Hi I’m Josh from eSpares. And in this video I’m going to be
showing you how to diagnose a faulty heater in a washing machine. Now the usual
symptom of a faulty heater is that the machine won’t finish a wash
cycle. And this is usually going to a result in
the machine either continuing to wash or in
displaying a fault code as it waits for the water to get up to
temperature. Obviously if the machine has a faulty element then the water is
never gonna get warm. Now safety first make sure you’ve unplugged your machine and in order to access the element on
most machines we need to get to the back although it may be on yours that you
access the element from the front of the machine. So I’m just going to turn this machine
round and remove the back panel. Now this is the element here under the drum,
I’m just gonna start by disconnecting the connections from the terminals. And then I’m gonna grab a multimeter and put that on to a low resistance setting. And
just place the probes if the meter onto the terminals of the element. Now for a working element
I’m looking for reading that between 20 and 50 ohms and on this 1 I’m getting about 27-28
so this should be okay. And next let’s have a
look at the temperature sensor which is next to the
element here. So I’m just going to pull that out disconnected
from its plug. And thrn if I put the meter on to a higher resistance setting and put the probes onto the terminals inside the sensor. For working sensor i’m looking fora reading.
between 20,000 and 50,000 homs. On this I’m getting about 47,000 so
that’s okay. And you can check the sensor is working
as well just by placing your hand over it and if it’s working the reading should
go down. Which it is so looks like the sensor is OK as well. Once you check both
the element on the sensor just have a look at all the wiring that surround it make
sure that it’s not burned or damaged or loose anywhere. And once you happy that the wiring is OK
and you still can’t find the source of the fault. It’s likely to be due to a problem
with the control board. Now if it is you can see more about how
to find out in another eSpares video. for washing machines and other
appliances are available on the eSpares website. Thanks for
watching.
