If your dishwasher is clogged then other problems can arise. It can be hard to tell if your dishwasher is clogged but it can depend on how often you use the dishwasher.
Weird Gurgling: One clear sign that something is wrong with the dishwasher is if there is a sound coming from the drains attached the appliance. The clogs may not be with appliance itself but in secondary lines or the sewer lines. When you hear this sign, you need to contact a plumber because you may need water heater repair.
Drain Is Slow: This is another obvious sign that something is wrong. The sink and dishwasher could both take time to drain. If the drains are slow, this means that there is a clog beginning but it hasn’t fully matured yet. This isn’t something you want to ignore since it can eventually block both the sink and dishwasher. You could flood your kitchen by accident.
Water Backups: Backups can be annoying. If the dishwasher is running, you don’t want to let other plumbing systems run at the same time.
A water backup in the sink can be a sign of a bigger problem. If you notice this, turn off the dishwasher and then run the garbage disposal to make sure you clear out any debris that could be causing this issue. If this doesn’t work then you need a plumber.
Residual Water: Residual water can make you feel uneasy. If you open the dishwasher and there is a puddle at the bottom or your dishes are still wet then drains aren’t working properly.
Dirty Dishes: Once you finish a dishwasher cycle you would expect everything to be clean. When your dishes aren’t clean, it could mean that water didn’t enter the dishwasher due to a clog.
