Kitchen sink waste going into washing machine!

[Yorkieman]

Thanks for all your suggestions rpm. As I mentioned I think wee will have to have a major reworking done of the whole system. It seems we have inherited a bit of a bodge job to be honest.

Thanks once again

Have you tried or could you try putting a drain auger (coil of wire) down the waste pipe after the trap to clean that out, could be part of the cause of the slow flow.

It doesnt need any special connections or fittings.
On the back of your washing machine there will/should be a plastic drain hose clip near the top of the machine. This should be well above the height of the sink connection.

I suspect your washer drain hose is just dangling at the back. It needs fixing securely at correct height.

If the clip is snapped then use a cable tie.

It is simply siphoning back in.
When the hose is fitted according to the manufacturer instructions this does not happen

Hi newcastle phill. Thanks for your reply. I haven't had time yet to check behind the washing machine but I'll certainly have a look ASAP. Very simple if this is the problem. Thanks :smug2:
