Washing machine connected to sink issue.

the_sphinx82

Hello, sorry I am no expert at all on this things.
My washing machine drain is connected under the kitchen sink (pic below).
It worked well until now (1 year more or less), but today when it was washing, the sink got full of dirty water and cannot manage to make it go away.
I tried with the plunger but nothing happened.
I had to stop the washing machine because was starting to overflow and removed the water by hand. I suspected that something is clogged or that something is not rightly connected. 
Could somebody have any advice here? Thanks in advance

I would say you have got a blockage - when the washing machine tried to drain - it couldn't so back-flowed into your sink.

You could put a bucket under the white connecting pipes and unscrew them and see if you can remove whatever debis is causing the block.

You need to take it apart and clean it all out.

Ideally you'd have a non-return valve on your washing machine pipe otherwise when you are trying to plunger it you'll be pushing crud back into your washing machine. 

Need a bucket under the u-bend and then unscrew and remove it. Hopefully the blockage is in there, if thats clear it's further along and will require rods/snake to try and clear it.

Thanks all for answering I will try now. I see that under the sink, where the washing machine drain is attached, there were two "parts" were it could be connected. Is it connected to the right one? Or should have been connected to the other one in picture (the one with the blue cap)? or it doesn't do any difference? Thanks again for your help to all

They both flow into the same place - I guess one might have been for a dish washer originally?

But, no it won't matter.

Try and remove most of the water from the sink before you start on the U bend. The less you have to catch below the less potential mess.

No difference, the second one is there in case you get a dishwasher or a tumble drier with a waste pipe etc

In terms of where the water is going, it makes no difference - all the waste water is going into the same drain.

But it looks like the washing machine waste is just poked into the drain hole?  Ideally it wants to be attached to the spigot on the right-hand-side.  Remove the blue blanking cap, push the washing machine hose onto the spigot and secure it with a Jubilee clip.  This will stop any water being able to flow back out of the open drain hole - once you've sorted out whatever is causing the existing blockage.

You then want to get a blanking plate to seal off the hole where the washing machine is currently draining into.  This type of plumbing is very standard, you should be able to find an appropriate-sized blanking plate just about anywhere for peanuts (any hardware shop, B&Q, Wickes, online, wherever).

Thank you all! this was so helpful! I did clean all the pipes (there was a big block of stuff in them that was surely blocking the pipe). and I am doing the changes you all suggested. thanks a million

It would be worth clearing filter on machine while you are at it,incase any debris has found it's way in there.
