Opening your dishwasher after a completed cycle only to find dishwasher not draining and standing water at the bottom can be frustrating. A dishwasher that won't drain properly may leave dishes dirty, create unpleasant odors, and eventually lead to water leaks if the issue isn't resolved.
Whether you own a Bosch, Miele, Thermador, Viking, KitchenAid, LG, Samsung, Whirlpool, or another premium dishwasher, drainage problems are among the most common repairs homeowners experience.
At Meraki Appliance Repair, we provide professional dishwasher repair throughout Los Angeles, including Beverly Hills, Pasadena, Santa Monica, South Bay, and surrounding communities.
Signs Your Dishwasher Not Draining
Your dishwasher may have a drainage problem if you notice:
Standing water after the cycle
Dishes remain dirty
Bad odors inside the dishwasher
Dishwasher stops mid-cycle
Error codes appear
Slow draining
Gurgling noises
Water leaking onto the floor
1. Clogged Dishwasher Filter
The dishwasher filter collects food particles before they reach the drain pump.
Over time, it can become clogged with:
Food debris
Grease
Paper labels
Broken glass
Small objects
Cleaning the filter regularly helps maintain proper drainage.
2. Blocked Drain Hose
A blocked or kinked drain hose can prevent wastewater from leaving the dishwasher.
Possible symptoms include:
Standing water
Slow draining
Gurgling sounds
Incomplete wash cycles
3. Faulty Drain Pump
The drain pump removes water from the dishwasher at the end of each cycle.
Common signs include:
Humming noise
Dishwasher won't drain
Water remains in the tub
Dishwasher stops before completing the cycle
A failed drain pump typically requires replacement.
4. Garbage Disposal or Air Gap Blockage
Many homes connect the dishwasher drain to the garbage disposal or an air gap.
Common problems include:
Food buildup
Clogged air gap
Disposal blockage
Knockout plug not removed after installing a new disposal
5. Drain Pump Obstruction
Small objects can block the drain pump impeller.
Examples include:
Glass fragments
Toothpicks
Fruit pits
Bones
Plastic pieces
Removing foreign objects often restores proper drainage.
6. Electronic Control Board Issues
Although less common, the control board may fail to activate the drain pump.
Possible symptoms:
Dishwasher freezes mid-cycle
Multiple functions stop working
Error codes
Intermittent drainage problems
Professional testing helps identify electronic failures before replacing expensive parts.

Frequently Asked Questions
Why is there standing water in my dishwasher?
The most common causes are a clogged filter, blocked drain hose, faulty drain pump, or a drain system obstruction.
Can I use my dishwasher if it isn't draining?
It's best not to. Running additional cycles may leave more standing water inside the dishwasher and could worsen the problem.
How often should I clean my dishwasher filter?
Most manufacturers recommend cleaning the filter about once a month, or more often if the dishwasher is used frequently.
Is it expensive to repair a dishwasher that won't drain?
The cost depends on the cause. Simple clogs are often inexpensive to fix, while replacing a drain pump or electronic component is generally more involved.
