Hi I'm Josh from eSpares.
And in this video I'll be helping you to diagnose leaking
and heating problems in your dishwasher. Let's start by looking at
leaking problems, now a dishwasher can leak in two ways.
Firstly by leaking water out to the dishwasher
and secondly by leaking internally. If we just take a look at the
door seal on the dishwasher.
The door seal isn't actually a complete seal
it's just a splash seal designed to deflect
any water of the door back into the tray.
Now if the dishwasher isn't on a level
or flat surface or it's leaning forward it's actually going to raise the water
level
in the tray. And if it gets any higher the seal
here it can actually leak out the front.
So make sure the dishwasher is
completely level and that'll help to avoid any
any leakage. Now if your dishwasher is level and you getting any
leakage
from the front it could be due to a problem with
the detergent either you've used too much detergent
or the wrong type of detergent. And as a result as a lot of foam
has leaked out of the front. Now if that's happened obviously
use less detergent and you can also run a cleaner through the system such as the
eSpares limescale and detergent remover.
And that'll help to flush any blockages through and keep the system
running properly. If you have had and any floods or leakages as a result of
the
detergent and you've checked that the water level in the tray
is at the correct level. It's a good idea to run the clean through
anyway just to make sure that the system is completely clear.
And you should also be cleaning a dishwasher with a proper cleaner on a
regular basis anyway just to keep the system
working at its most effective. Now you can also get
leaks as a result of condensation forming
after the dishwasher has finished a cycle
you can get steam coming out at the gap in the top of the door.
And if the dishwasher is underneath a work surface this steam can condense
on the underside of the work surface and then drip down
onto the floor.So if you are finding this just grab a cloth and give the underside
of the work surface a wipe and this
should help too avoid the problem. If you are finding that there's an
excessive amount of condensation forming on the other hand
it might actually be that you need to replace the
door seal inside because it's letting too much steam out. And you can see how
to do that in another eSpares video.
You can also get leaks forming as a result of damage
to both the drain hose or the
inlet hose. Obviously if there's any tears or damage in the material that's going to
let water out. Also check the washers
on the ends of the inlet hose. If the rubber has perished in any way
they're obviously not gonna form a proper seal and that's gonna let water out.
Just replace those parts as necessary
Now covers the main external leaks
on a dishwasher. Now I'm going to put the dishwasher down onto its back and we'll
take a look at
internal links are taken the base
of the dishwasher. And the first thing we can see is this
anti flood switch here . The base
is actually a very shallow to tray and is designed so that
if they're is any internal leakage. The water can build up to a low-level
in that right. Now if it does that it will gradually raise
this polystyrene float and once It gets
to a certain level it'll activate the anti flood switch.
Now you know if there is afloat in the tray because when you first turn
your dishwasher on and you make a combination
all lights and beeps.
And you may have the pump running continuously as it tries to drain the
water away.
You can check if there's any water in the base just by tipping
the dishwasher slightly to one side and obviously if any water runs out that
would indicate there's a buildup in the base.
So just get rid of any water and that'll brings the float
back down and deactivate the switch and you should be able to
use your dishwasher again. Now to give you one a better look inside
the dishwasher I'm just going to remove the anti flood switch so I can fully
removed the base.
Okay so now I've got the base of we can have a look inside.
Now the source of the leakage will come from anywhere they obviously comes
into contact with
water so the sump the hoses
and the pump. Just have a look for any holes or damage to the material anywhere
obviously if you do you find anything and you just need to
replace the part as necessary. On the other hand if you can find any holes
in any of those parts and you can see any rust or discoloration
and in this sort of area here. It may be that the
seals in the sump are damaged.
In which case remove the sump and have a look at the seals
if they are dirty give them a good clean or replace them altogether
and then refit the sump. If you still can't find any problems with the seals
in the sump
the flooding may simply have been caused by too much foaming.
In which case reassemble the dishwasher pop the float switch
and the base back on and try it again.
While I've got the dishwasher on its back let's have a look at heating problems.
You usually know if a dishwasher has a heating problem
because it won't finish a wash cycle. It's going to keep
washing while it waits for the water to get up to temperature.
But obviously if there's a heating problem and it's never going to do that
Now dishwasher have two different types of heaters.
One is this standard element type
and this is located usually underneath
the tub. The other type of heater which is the one in this dishwasher
has a flow-through heater located here
in the base. Now you can test both types for whether they're working
just using a multimeter on a low resistance
setting. So just disconnect the heater
and place the probes onto the terminals
of the heater. And for a working heater you looking for reading of
around about 30 ohms although it could be about 5 ohms
either way now that's what I'm getting about 34 or
35 ohms so that shows that this one should be okay.
Now if your dishwasher uses
this type of heater it may also have a thermostat
or thermal cut-out fitted some where near to it
usually on the underside of the tub.
Now if thats faulty it's obviously going to cause a problem and you can test again
using your multimeter if the thermostat
is faulty it'll read as a infinite
circuits and give no reading on the meter.
On the other hand if it's working is a short circuit so
less than a couple of ohms. Obviously if you're not getting a short circuit
reading many need to replace that thermostat.
If you dishwasher uses this flow through heater
it'll probably also be fitted with a thermal sensor
some where in the door. Now the thermal sensors don't tend to fail
and they usually only available as part of the control board
So if you've checked all these other a reasons and you can't find a fault.
The chances are you just need to replace the control board
to resolve the issue. Now if you need help
diagnosing any other faults in your dishwasher check out our other
eSpares videos. And spares for dishwashers along with other appliances are
available on the espares website. Thanks for watching.
