Connecting washing machine waste under sink

Hi everyone,
I've just started renting a new flat. It's a new-build and the owner had never installed a washing machine so I've just bought one. I'm going to connect it myself but have realised that the drain hose is going to have to connect to the waste trap underneath the kitchen sink, as there isn't a standing pipe for it to go into.

The washing machine has arrived today and I can see that the end of the hose will fit tightly over the inlet (see images - haven't connected everything up yet, just wanted to check the hose would fit), however I'm going to also add a jubilee clip to make sure it's extra secure. Is there anything else I should do? I've read a few things about this kind of connection causing water from the sink to end up in the washing machine, which I obviously don't want!

As above and make sure hose from the washing machine loops up before going back to the machine. Appliance will pump the water out quite happily, whereas gravity flow from the sink wont go back uphill.

Also ... buy a jubilee clip or a large thick tie wrap just to secure the rubber end onto the spigot properly, don't want that popping off under full flow drain cycle.

Apologies for being thick, but what do you mean by "make sure hose from the washing machine loops up before going back to the machine"? Thanks.
 
Looks to me like you'll have done that already - ie don't turn that spigot downwards. There is normally a blank under the ~3cm nut where the spigot swivels.

Hose needs to go up to around the height of the machine, before dropping down to the drain point, where it connects onto the sink. Frank has given a perfect illustration in the photo above of how it should be done. This is done to prevent any discharge from the sink finding its way into the washing machine.
 
Hi, I paid delivery mens£50 to install my new washing machine they haven’t levelled it properly but do you think the connections are ok? I had to get them back the first time it was leaking everywhere and they blamed the spigot thing under the sink but it was brand new so they fitted the old one full of sludge , do you think I will get any back flow into the machine? The sing gurgles when draining and a bit of water comes up through plug hole

Do you think the spigot thing needs to be more up right like the person’s who started this thread?
 
Its better to start a new thread rather than resurrecting an old one, but,
Your problem is that horrible flexible concertina type waste pipe from the trap outlet. Get that changed for 40mm pipe, all the seals checked and make sure you clear any blockages.
 
Pritchy, Looks like the pipe from your sink overflow is missing, it's the white stub of rectangular pipe (side of sink) in your first photo.
 
Yes I know it’s been like that since so moved here I don’t know how to fix it or what part I need, but do you think my washing machine is ok for now or will the water back flow into the machine?
