Hello everybody 'Lurgs' here welcome to my channel and today it's what to do if
your Bosch dishwasher is not draining water so you've just done a dishwashing programme
everything's come out clean but you've still got standing water in the bottom of your dishwasher
this might be filthy dirty and a bit stinky. Today there'll be two steps first we'll check the filter
and hopefully that will get it fixed if not we will then check the drainage pipework but first
we're going to check the filter now the first thing you must do is switch off the dishwasher and
unplug it just to be 100% safe this is the Bosch dishwasher here so just open up the front door
first thing you need to do is remove the bottom basket this literally just rolls out
and you can also remove the top basket if you want to you don't have to do this but it'll just make
it a bit easier for the access to the filter this literally just lifts up and off and there's a link
above about how to adjust the height of this top basket, get rid of any excess water in the
bottom of the dishwasher just using a sponge and a bucket just get rid of as much of this as possible
If you want to you can pop off this lower spray on to give you easier access to the
filter but you don't have to, okay so the filter is here and when these two arrows are lined up
that means that it's locked into position
now to remove the filter you literally just turn it anti-clockwise about 90 degrees
And then you just lift it upwards now depending on how clean your dishes are when you put them
in the dishwasher depends how dirty this filter is now we're pretty careful with the dishwasher
but that is pretty disgusting if you don't clean off your dishes before you put them in
this will get clogged up on a weekly basis now this filter element just literally just pops off
this makes it a little bit easier just to give it a good clean now don't clean it straight into
the sink otherwise you'll be watching a video on how to unblock your sink! So take your partner's
toothbrush and just get off as much dirt and debris and put that straight in the rubbish bin
likewise with the cover here just get as much of that off as you can
This is just general grease and fat pretty disgusting
then fill up your sink with some hot soapy water again take your partner's toothbrush and just
give this a really good scrub so it's coming out sparkling clean now I don't need to show you all
this footage so I'll just cut this footage short but you're basically just making sure
this is in tip-top condition before we put it back
Now before we put it back we're going to check the impeller just to make sure that isn't blocked
Now this filter just literally just pushes back on and there we go it's in position
now before we put that back in we're just going to check the impeller so take an old sponge and
just get rid of any excess water inside here and just squeeze that into a bucket
while I'm doing that there's a link above now about how to add Salt
to this Bosch dishwasher it's really important to add salt if you live in a hard water area
So just drain that out completely as much as you can if you haven't got a sponge a turkey
baster is a good idea to get the excess water out and then to get to the impeller or propeller
you just need to remove this plastic clip here so just take a blunt instrument don't take anything
sharp I've just got this teaspoon here and what you're doing is you're gently prizing it outwards
until that clip comes out and then you can just lift it upwards and outwards and then we should
be able to see the impeller \ propeller and there it is at the bottom now the prime suspect
for blockages in here is broken bits of china bits of glass or sweetcorn and bits of food,
now this one is actually pretty good but here's another one from another dishwasher that I
serviced and you can see here it's got bits of hair in it and an old raisin so I've just got my
partners I think they're eyebrow clippers or eyebrow removers I don't know what they are anyway
I'm just using those to get out any bits of debris if you can't get access to any of the debris try
just getting rid of as much water as you can so it's nice and dry and then just get your vacuum
cleaner nozzle and just use that if you've got a wet and dry vacuum cleaner that'll be ideal
or maybe a turkey baster to try and get any excess water and debris out, just a word of caution if
you're using your fingers down here just be very careful because there might be bits of
broken china or bits of broken glass as they are prime suspects for stopping the impellers spinning
Now to put this clip back in it literally just slides down
and then just pops in, whilst I'm doing that there's a link above now about how to add
Rinse Aid to your Bosch dishwasher that will keep your glasses and plates sparkling clean
Well we can now put the filter back in don't try and force it this should just lay in very easily
there we go
and then to lock it in just turn it clockwise about 90 degrees until those arrows line up
that is all nicely locked in fabulous
Then remember to plug the Bosch dishwasher back in and switch it on and then it's a good idea to
run the dishwasher cleaning programme so I've just got some Finish dishwasher cleaner here
you just peel the label off the top
this gives your dishwasher a really good deep clean and keeps it hygienically fresh
and hopefully flushes out your whole dishwasher system and hopefully no more blockages
so pop that in and run the hottest dishwashing cycle that there is
and then hopefully your dishwasher is draining water properly
and when you open the dishwasher there's no excess water in the bottom and the dishwasher
is smelling absolutely fabulous.
Great stuff now if this hasn't cured your dishwasher not draining water
we can move on to the next step and the next step is to check the drainage pipework if you
didn't do it earlier make sure you switch off the Bosch dishwasher and unplug it just to be
100% safe and it's a good idea to isolate the cold water supply into the back of your dishwasher just
in case there's any plumbing issues if you don't know where that is locate your main stopcock and
turn the mains cold water off there, it's a good idea to know where your main stopcock is in case
you've got any plumbing issues if you can't locate that then turn it off in the street but don't do
that if you live in a block of flats because otherwise everyone is going to lose their water!
And there's generally two types of drainage pipework the pipe work like this where it
goes into your under sink unit into a U-bend and there's another type where it literally goes to
the back of your dishwasher we've just got some pipework on the wall so we'll concentrate on that
one first, I'll show you the under sink pipework later on after this one. If the drainage hose
from your dishwasher doesn't go to your under sink unit you need to pull your dishwasher out
be careful not to pull it out too far because obviously you've got the cold water mains feed
and the drainage hose in the back so just pull it out gently dishwashers aren't very heavy so
they're quite simple to pull out and that is the drainage pipework at the back there so you've got
your cold water mains feed into the back of the dishwasher which you've already isolated
and this is the drainage hose and we're going to be checking this U-bend here,
so remove your drainage hose it literally just pulls out check for any blockages
inside this one's actually not too bad but there's lots of sludge on the outside
so give that a really good clean in some hot soapy water and the easiest way to check for
any blockages inside this drainage pipework is to take your phone put it into video mode with the
flashlight on and just video down inside there check the footage and see if you can see clear
water or any sludge this one actually doesn't look too bad but I'm just going to remove the U-bend at
the bottom of this drainage pipework just to show you how this works, now the U-bend is there to
stop any smells coming back into the kitchen and it also helps catch any sludge and grime
so just undo these nuts here hopefully nobody's glued them on and they're easy to remove
make sure you've got a tray ready and an old towel because you will get some water out of here
That is now disconnected and this water is actually not looking too bad so I'm just
going to drain that into the sink but if that was full of sludge make sure you put that in the bin
and then give it a really good clean with hot soapy water and make sure that's nice and clear
if that was full of sludge that wouldn't be helping with your dishwasher draining water
this is now ready to go back on so we just tighten these nuts up here
And then very important remember to put your dishwasher drainage hose back down
inside the drainage pipework otherwise next time you run a dishwashing programme
you're going to get water all over the floor, now don't push this all the way
down to the bottom just rest it in the top between eight inches half a foot to a foot
and the other type is the drainage hose going into your under sink unit
again have a bucket ready for any excess water
and you're checking for any blockages this one is actually not looking too bad
the hose and the connector are free of any
blockages so I can just put that back on, this one's got a metal clip as well,
and as previously if you undo these nuts here and check for any sludge in this U-bend
if that is full of sludge put that in the bin make sure it's nice and clear and then reinstall it
then remember to plug your Bosch dishwasher back in and switch it on and also remember to
turn the cold water mains feed back on as well, and then it's a good idea to run the dishwasher
cleaning programme, so I've just got some Finish dishwasher cleaner here you just peel the label
off the top this gives your dishwasher a really good deep clean and keeps it hygienically fresh
and hopefully flush out your whole dishwasher system and hopefully no more blockages!
So pop that in and run the hottest dishwashing cycle that there is
And I hope that's fixed your dishwasher not draining water and it's draining successfully,
if it still isn't draining water then I suggest you go outside lift any drain hole or manhole
covers see if you've got any blockages in your drainage system if you cannot get access to
that I recommend you get a CCTV drainage survey done to make sure they're all nice and clear, if
that's still not working it could be a dishwasher drainage pump fault in which case you'll need an
engineer to come out and have a look at that or it could be a computer board fault, to help with
ventilation always leave the dishwasher door slightly ajar after a dishwashing programme
stops it smelling, I'll tell you what I think that definitely deserves a lovely cup of tea!
Whilst I'm having a cup of tea on the top left there's a link on how to keep your curtains
super smooth on the curtain rails that is a top tip and on the top right how to disconnect a
dishwasher and in the bottom left how to install a brand new dishwasher catch you later. 'Lurgs'.
