Sink drain water feeding back into dishwasher through side vent
crwdns2934249:0crwdne2934249:0:
When I run water down the sink drain (dishwasher is not on), it trickles into the dishwasher through the side vent. I raised the drain hose and the water coming through the vent increased. I pulled the dw drain hose off the sink drain and water came out as if it were under pressure but it did not drain the dishwasher. Any idea what is causing this problem ?
