[J-mac]

I was hoping someone will be able to help me. We bought an indesit dishwasher at the weekend, we had to use a 'Y' connector for the washing machine & dishwasher waste. Now when the the dishwasher has been used. the washing machine needs to be drained of water, could some one please help me this wasn’t a problem with my washing machine previously.
thanking you for your assistance

you have to loop each waste pipe up, above the level of the join and above the level of the trap.
