Dishwasher not draining? No need to panic! Below, we’re sharing the most common causes of dishwasher clogs, how to fix them – and how to prevent them from happening in the first place!
How to Fix Your Dishwasher Clog
How to fix a dishwasher clog will depend on the root cause of the issue.
How to Diagnose the Issue
- Inspect the drain for visible signs of food, debris, or soap scum.
- Check for visible signs of grease or other residue on glassware and dishes after being washed.
- Consider any foul odors coming from the dishwasher.
Common Causes of Dishwasher Clogs
Food Particles and Debris
Food particles and debris can easily accumulate in the dishwasher drain or filter, leading to clogs if left unchecked over time.
How to Fix
Remove the lower rack of the dishwasher and clear out any visible food particles or debris from the drain and filter. You can also use a toothbrush to scrub off any stubborn residue.
Hard Water Deposits
Hard water can leave mineral deposits in the dishwasher’s spray arms, filter, and drain, leading to clogs. Your first clue this could be the issue? Glassware washed in the dishwasher often appears cloudy or spotted.
How to Fix
Use a dishwasher cleaner designed to remove hard water deposits. You’ll want to regularly clean the spray arms, filter, and drain to prevent buildup.
Grease and Soap Scum Buildup
Grease and soap scum can accumulate in the dishwasher’s drain line. If you can see a buildup of grease and soap scum anywhere near the drain area or filter, it’s the likely culprit of your clog.
How to Fix
Run a cycle with a dishwasher cleaner or a mixture of even parts vinegar and baking soda to break down grease and soap scum. You can also remove and clean the drain line if it’s accessible.
Faulty Drain Pump
If there are no visible signs within the dishwasher drain itself, you are potentially dealing with a malfunctioning drain pump. This pump, located at the bottom of the dishwasher near the back, is what prevents water from draining properly at the end of each cycle.
How to Fix
If accessible, inspect the drain pump for any obstructions or damage. If the pump is faulty, it will likely need to be replaced by a professional plumber.
How to Prevent Dishwasher Clogs
Regular maintenance and mindful usage are key to ensuring your dishwasher provides years of reliable service. With a little effort, you can prevent clogs and keep your dishwasher in top condition, making your life easier and your dishes cleaner.
There are several measures you can take to ensure your dishwasher stays clog-free and functioning efficiently, including:
Rinse Dishes Before Loading
Do your best to remove large food particles and debris from your dishes before placing them in the dishwasher.
Clean the Filter Regularly
Most dishwashers have a filter that catches food particles. Check and clean this filter regularly to prevent build-up that can lead to clogs.
Run Hot Water in the Sink Before Starting the Dishwasher
This ensures that hot water enters the dishwasher immediately, helping to break down food particles more quickly.
Avoid Overloading the Dishwasher
Overloading can prevent water and detergent from circulating properly, leading to residue build-up.
Use the Right Detergent
Use a high-quality dishwasher detergent — and not too much, as that can cause residue build-up over time.
Check the Garbage Disposal
If your dishwasher is connected to a garbage disposal, periodically check that it’s clear of debris.
Clean the Spray Arms
Occasionally remove and clean the spray arms to ensure that water can flow freely through the nozzles.
Regular Maintenance
Schedule regular maintenance checks to catch potential issues before they become bigger problems.
