Hi I'm Mat from eSpares. In this video
I'll be helping you diagnose dryer problems with your washer dryer.
Now the machine we using for this is a Hoover washer/dryer,
but the process to be very similar for most makes & manufacturers.
Now if you have a problem with a washer dryer that isn't about the drying
section
please see our other diagnosis videos. Firstly a quick
explanation of your washer dryer. If you set it to a wash
rinse or spin cycle the machine behave as a standard washing machine.
However if you've also set the drying function the machine will continue to
tumble the drum
as hot air is passed through it.
So I've just turn the machine off and I'll take the lid off so we can see inside.
And here we have
the typical components of motor
and fan, heater box
with the elements and thermostats
or cut outs, and at the rear the machine
is the condenser. The fan pushes air
through the heater box this hot air then enters the drum
here. The hot air is then passed through the washing load
where it absorbs moisture. Moist air exits the back of the drum
via this hose where it enters the water cooled condenser
drawing out the moisture. This air then re enters the fan
and then is heated again. Now we have explain how the drying part works
let's have a look at some other common problems. The first thing I'm going to
check
is the elements. This washer dryer has two heater elements
one on top of the other, and a really easy way to check
these is to use a multimeter. I'm just going to disconnect one of the
electrical connectors
so that I get an accurate reading from the element and nothing else.
The reading you're looking for
is between 25 and the 150 ohms,
anything outside of this your element is likely to be faulty.
With the machine set to its lowest resistance setting
the reading we are getting from the elements
is around 80 ohms. So this element is fine.
The next thing I'm going to check is the thermostats
or cut outs. Using a multimeter
if you cross the probes the reading
should be very similar to that
across the thermostats as you can see these thermostats
are fine. The next place a check is the fan
now fluff or lint can enter the fan stopping it from spinning effectively.
A very easy way to check the fan is to spin the motor cooling fan
on the outside which is connected to the heater fan
via a spindle. This is spinning very freely
not obstructed. Now if you have a very high resistance reading
and your thermostats have these buttons on the top
press those, that effectively resets that then the stance
You can also check your motor using your multimeter,
a reading at below 500 ohms means the motor is fine.
If you washing is taking a long time to dry but is coming out very hot
it could be that water is not being fed into the condenser.
Simply follow the hose from the condenser
to the relevant valve and then you can check this with your multimeter.
A reading of
around 4,000 ohms means the valve
is fine. And those are the common problems.
