A clogged air gap can cause a dishwasher not to drain. There are, however, other potential issues that can lead to improper drainage. For example, if you have attached the air gap to a garbage disposal and forgotten to remove the knockout plug, wastewater may backflow into the dishwasher. Check that the air gap is installed properly, and then look for clogs in the air gap and dishwasher filters. 

The cost to repair a dishwasher is $200 on average, with the typical price ranging from $160 to $300. However, if you need a more specialized repair, that total could reach $600. The main cost factor is the price of the replacement part, but the dishwasher’s make, model, and year can also impact the price. 

For a simple repair, such as a filter replacement, you can comfortably budget to spend between $50 to $100. But for something more complex like a repair on the dishwasher’s motor, you might see a bill totaling $400 to $600.

It might be time to buy a new dishwasher for your kitchen if you consistently notice a significant amount of water left over after a cycle, indicating potential drainage issues that are becoming persistent or costly to fix. Visible rust, especially on the interior tub or racks, suggests internal corrosion that will likely worsen over time and can compromise cleaning performance. Additionally, if your dishes are coming out excessively hot after the drying cycle, it could point to a malfunctioning heating element or thermostat, which can be an energy inefficiency and a potential safety concern, making replacement a feasible choice.

Some signs that your dishwasher is going out include:

• The door no longer latches 

• Dishes are still dirty after a cycle 

• Dishes are cold after a cycle 

• Rust inside or outside the unit 

• Cracks inside the dishwasher tub

• Water collecting at the bottom or outside the unit

If your dishwasher is not energy-efficient or is older than 10 years, you should also consider replacing it. Repairing an older model may be more expensive than replacing it with something newer and more energy- or water-efficient.
