There's nothing more annoying than an appliance that won't work properly – especially when you really need it to! If your dishwasher is not draining, it may be a case of a clogged sewer line. Dishwashers are connected to your kitchen sink's water supply line and drain system. If either of these becomes clogged, your dishwasher won't get all the water it needs to clean the dishes. Food or other debris could be the culprit, but whatever the case, it's important to recognize the signs of a clogged dishwasher so you can get it repaired immediately.
1. Gurgling. If you hear an unusual gurgling sound coming from your drains, this could be water attempting to break through a roadblock, so to speak. Clogs can occur in your main sewer line or secondary lines, so if you hear this noise, be sure to get a plumber out to diagnose the location of the clog.
2. Slow-flowing drain. If you can tell your dishwasher or kitchen sink is draining slowly, there might be a near-clog in your kitchen sewer line. You'll want to get help as soon as possible, because that near-clog could lead to a fully clogged dishwasher and kitchen sink.
3. Water backup. If your dishwasher is running and water is backing up out of the kitchen sink, there might be a problem. Shut off the dishwasher and run the garbage disposal to ensure there's no food stuck in the sink or causing a clog. If the water backup persists, call a plumber immediately.
4. Leftover water. If you open the dishwasher after its cycle is complete and discover water resting in the bottom, that means the appliance didn't drain properly – and you've got a problem on your hands! Troubleshoot to discover the cause of your clogged dishwasher or call in the experts.
5. Unclean dishes. Likewise, if you open the dishwasher after it has run and find your dishes are not clean, that could mean it didn't actually fill with water. This would indicate a clog in the main line or secondary kitchen line.
