In many homes, kitchen appliances and the washer drain through the same pipe. Grease and food often build up in that pipe, slowing the water flow. If it gets bad enough, it might stop altogether. This not only backs up kitchen appliances but can also back up your washing machine as well.

Visible build-up of food in the filter. Water not draining properly. Nasty and unpleasant odours.
Most dishwashers feature a long drain hose that connects the appliance to either an air gap or disposal hookup for drainage. And over time, these hoses can easily become kinked, twisted, detached, or blocked – all of which prevent proper discharge and lead to water backups.

Drain Clogs
As the dishwasher pumps out water, the clog can cause a backup, resulting in water filling the sink. Solution: Start by using a plunger to attempt to dislodge the clog. If that doesn't work, try a drain snake or a mixture of baking soda and vinegar to break down the blockage.
Kitchen Sink Clogged Drain
When there is a clog in the line, and it's not draining properly, water pressure in the pipes can increase and force sink water up into the dishwasher drain line. One way to relieve the pressure is to disconnect the sink trap (P trap) underneath the sink and remove the blockage.
Clean the drain
Since it is common for debris to get stuck in the dishwasher drain, try cleaning it with a solution of equal parts baking soda and vinegar. Pour the baking soda and vinegar into the bottom of the dishwasher and let it sit for 15 minutes. Then run a rinse cycle at the highest heat setting.
