Gurgling Sink with New Washing Machine

[EastMidsTiler]

Hi All,

Had to replace our integrated washing over the weekend, almost a straight swap except for hinge position on cupboard door (nightmare!).

Now when the washing machine is draining we are getting a gurgling sound from the sink. The washing machine is slightly bigger so maybe have a stronger drain pump on it but apart from that everything else is set-up exactly as before. This was never an issue in the past.

The gurgling noise is quite loud and annoying.

I've attached some photos of the current set-up. Anything obviously wrong with this?

I've already tried putting the plug in the sinks and that does seem to quieten the noise somewhat but certainly not stopping it.
The trap is clear. The sink drains fine as well. never been any indication of a blockage. Must be related to the washing machine swap.

Every household needs a sink plunger (or 2). There's a technique as well. Check YouTube. Go round all the sinks, baths, basins and showers and give them a little "love".

So update time...

This morning I ran a cycle and emptied into buckets just to check it wasn't the machine as advised in this thread. No noise and everything fine. However I can now appreciate the volume of water the machine uses. It filled a standard builders bucket 3 times over in a 45 min cycle. It filled the bucket each time within 20 secs so can appreciate that volume of water going through the trap etc etc.

I then switched the Dishwasher and WM hoses, and that actually caused more noise not just a gurgling but also you could hear the running water very clearly. The DW spigot is further away from the trap, closer to the sink.

So I've Amazon primed a plunger today and will be going around the house tomorrow plunging everything. Fingers crossed for that. I'm starting to think the only option is to have the WM on its own waste however in this new build house everything is hidden, there are no visible drain covers etc so I think we be a more difficult and expensive job.

Agree it’s water noise eg swirling around and gurgling around the trap tbh I don’t think you will totally get rid of the noise unless you put it on it’s own trap

Plunging everything has helped quiet the noise a little to a point where if the plug is in the sink the gurgling noise is barely audible. A partial success. Happy to leave it like this for now.

There was nothing visible coming up when plunging which was a little disappointing but it certainly has had some effect at least.
