Washing machine waste overflowing under sink.

NSG666

For now, nothing need connecting or disconnecting and the washing machine does not need to be removed.

To clarify terminology:

Inlet hose - connects the machine to a cold water supply (the hose with the blue ends)

Outlet hose - comes pre-fitted to the appliance to empty the machine (the hoses coming in at the top of the cupboard

Waste pipe - the pipe the outlet hose connects / is pushed in to (the pipe going down through the cupboard shelf)

Trap - the U bend (possibly under the shelf)

 

Photo of the waste pipe and trap under the shelf please.

Those are push-fit pipes so can be (with some effort) pulled apart and re-assembled.

But there must be a trap beneath the shelf (remove shelf to have easier access) to prevent drain smells backing up...  

Less than ideal to have two appliances into the one waste... the one on the right will flow slower due to the two right angle turns... if that's the washer, swap them over as it'll be pumping more water out than a dishwasher will.

After cleaning the trap etc.,. thoroughly, of course.

Afterthought: 
Neither of the two corrugated waste pipes look clean and brand new to me (but it's a poorly lit picture).
Where are the washer and dishwasher located relative to that cupboard? 
(I'm thinking a waste hose joined to extend the hose on the machine, and that may be an issue/leak point?  If, say the dishwasher is on the right, next to that cupboard and the washing machine is to the right of the dishwasher...?)

Thanks to all again, The washer is just to the right and the dishwasher is to the right of that about a metre away.

I think its pretty obvious I am not well up on washing machine terminology, i.e not knowing an inlet pipe from the waste, and thank you all again for coming back time again to advice me.

I have someone coming next few days to sort it out, hopefully they can (at the moment pulling or tugging at a washer if that was necessary I am not able to do due to medical circumstances)

Though I will try a few simple DIY when able I just feel I need to get someone in this time to sort it out. Will give an update when hopefully its sorted.

Thanks to everyone once again.

Here's my take on this. I'm betting that the outlet hose from the new machine is the one feeding into the right hand piece of vertical waste pipe in the photo. If so, perhaps the flow of waste water from the new machine is so fierce that it's hitting that right angle joint and the water is backing up rather than flowing away. An easy way to test this is to swop the outlet hoses over.  Just take each flexible hose out and insert each one in the other waste pipe. If that works, hopefully the flow of waste from the dishwasher is less fierce and will get past that right angle bend. Worth a try.

I think that right hand bit of waste pipe is far too short. It should be much longer before the angle joint and the joint should be of the 'swept' type  - a curved bend rather than a sharp right angle

You could well be right in that, but as I had the guy booked to come and was so fed up with the water spill I just let him come and have a look, anyway the young chap said that he has seen this before and says he fitted a new pump that has not a strong an action, so £40 in total, hopefully its all sorted now..

I would have tried the swap over earlier if I had coped on, but a little bit of an illusion seeing the water coming out of the pipe which I assumed was the pipe the washer was hooked into. its only when I put on the dishwasher and that pipe started to warm up that I realised the washer was probably on the other short side with the right angle.

Anyway I live and learn, has given me a whole new understanding of the horrible situation of what it must be like for someone to have their house flooded.

Thanks so much to everyone once again who have been so helpful in trying to advice me along the way .

Blimey! His solution was to fit a less-powerful pump! I guess that's 'clever' is a weird kind of way :-)

And this was only £40 all-in?! Good grief!

Yeah I know, that's what I thought too, not expensive, all I know is he has got almost 90 excellent Google reviews with countless people saying he is so easy to pay, unlike some other local tradesmen here where I live.
