My washing machine isnt draining despite me opening filter, I am not sure if the blockage is in the machine or the pipe because the drum itself isnt emptying at all, if I get the door to unlock I manually scoop out all but about a cup or two worth of water and then when I open filter the drum empties instantly and goes through filter (which I assume if there was a blockage before the pump then opening the filter wouldnt drain instantly!)

Last time I had a problem I just removed the tube from the u bend and poured thin bleach down it and it worked once(which supports the pipe blockage theory) so I want to unscrew the u bend part and get any gunk out of it.

I also cleaned the top of the pipe then blew into it(no jokes lol) and this got out a little bit of water in the pipe and some dirt, I then poured a little boiling water in and a trickle came out, blew it again and the water poured out with more dirt.

3rd time I put in some brown vinegar which just went straight through and got some more dirt(but still nothing that would cause a blockage unless it was all in one lump.

The u bend I want to try now and test machine tomorrow, my water is draining fine from sink so if there is a blockage its minor.

Probably best to upload some images or have a look for your u bend on youtube here

If I'm reading this right, your water is draining from the sink fine, which would indicate to me there is no issue with your u bend. The easiest solution would be for you to disconnect the waste pipe from the washing machine and test the washing machine with the waste pipe in a bucket or hanging out the back door.
Removing the filter will always drain the water, it's gravity. Regardless of the pump.
If slight blockages are affecting your machine, maybe the pump is on its last legs.
As for removing the U bend, it should just be fixed in before and after the bend with threaded grips - turn them with your hands.

It's most likely the machine and not the pipe. Your u bend shouldn't block up unless you're doing something antisocial like pouring fat down it.
Disconnect the the mains from the washing machine and then the waste water pipe from it. Put the pipe in a bucket and drain the machine. Could be a valve or impeller that has failed on the washing machine. Sometimes you can have small coins or screws jamming the impeller.

Well I cook fod in its own juices so only a few drips of oil go down the sink, I do use strong powder I think, its the stuff that comes in a plain white tub meant for things like hotels and schools(so it says) so wonder if its just made a lot of gunk.

I did try a quick wash just after I drained machine and all the water drained out and had no problems, the drum was empty and only a small amount of water(less than a cups worth) in filter

Hoping this means its fixed, and yes its the grips I wanted to remove just to double check theres no gunk, anda even if its just a tiny bit that shouldnt cause problems I want to clean it anyway.

A Regular U Bend should undo by hand by turning the bits at the end. However if, as you describe, the sink goes through the same U bend then that would confirm the U bend is OK. Sometimes washing machines have a separate u bend with a vertical pipe coming out. If you have this type - either dismantle it or tip some water down the vertical part.

I've had this problem twice on washing machines, the first time the pump in the washing machine had failed. The second time a kids bracelet had wrapped round the impeller on the pump stopping it turning.

Both were easy to fix by lying the machine down, didn't need specialist tools etc.

Yeah that describes my one the normal pipe from sink going down then near the bottom it curves to the left as well then has a u bend then a large pipe going back up so I was assuming something may got blocked at bottom.

I do not think the pump is dead as I can hear something moving and did try with an open filter to put a small long bit of card in it(dodgy I know) and I heard the pump)

Now I spent that time blowing into pipe and putting boiling water through it, the quick wash worked, drum was empty and I heard a little bubbling in the actual sink(not much) so that means water is getting pumped there.

Could be something with the pump though as when I first moved in I found a babies sock and loads of pebbles in the machine, last tenant must of taken a child to the beach.

Likelihood is some tissue or paper got into a wash and is blocking the drainage pump.

We had the same on out hotpoint, and I had to strip it down to fix it.
#8
Well until I do another wash at least I cant tell if its fixed, as the time before this I had problem I put some bleach down u bend and washing machine worked once then didnt drain again, so if it drains next time it still doesnt mean it is working and I do about 1 wash a week.

Bleach wouldn't clear a blockage.
#10
have you changed your washing powder or liquid recently, same happened to me machine not properly draining , i went on internet and said to check filters and also use pipe cleaner such as soda chrystals and then a v hot wash , i did this and the machine worked beautifully after and continues to do so.

I did try a load today but I had a sleeping bag and towel and dressing gown so may of been too heavy for machine, it didnt drain again but unlike normal the drum was almost empty and the water was in the actual filter so it seems its draining down the seal as its meant to and getting blocked somewhere else.

I wonder if the motor is rusty still as the filter area has some rust on it or something like that.
#12
I tried it again today and again it didnt drain, I have decided to risk removing the pump, currently have it on its side but cant find my pliers! I think its the best thing to do before calling in repair man

I notice the sump hose has no ball no idea if thats the problem but no blockages anywhere apart from some grit in the hose that goes out the back.

Now its a case of remembering how to put things back in correct and making sure the clamps are on the hoses.
