Why Is My Dishwasher Only Cleaning The Bottom? Here’s The Answer!

Dishwashers are a modern convenience that can save time and energy. However, when your dishwasher isn’t cleaning the bottom of your dishes, it can be a frustrating problem. In this blog post, we’ll explore the reasons why your dishwasher may only be cleaning the bottom and provide step-by-step instructions on how to troubleshoot and fix the issue.

Clogged Spray Arm Holes

One of the most common reasons why a dishwasher only cleans the bottom is because the spray arm holes are clogged. Over time, food particles, grease, and mineral deposits can accumulate in these holes, blocking the water flow and preventing the spray arms from rotating properly.

Solution:

1. Remove the spray arms from the dishwasher.
2. Use a toothpick or a small brush to clean out any visible clogs from the holes.
3. Soak the spray arms in a mixture of hot water and white vinegar for 30 minutes to dissolve any remaining clogs.
4. Rinse the spray arms thoroughly and reinstall them.

Blocked Drain Filter

The drain filter is another potential source of clogs that can prevent your dishwasher from cleaning the bottom. The filter traps food particles and other debris to prevent them from clogging the drain hose. However, if the filter becomes clogged, it can restrict the flow of water and prevent the dishwasher from properly cleaning the dishes.

Solution:

1. Locate the drain filter at the bottom of the dishwasher.
2. Remove the filter and clean it with hot water and a sponge.
3. Check the drain hose for any kinks or blockages.
4. Reinstall the drain filter.

Faulty Water Pump

The water pump is responsible for circulating water throughout the dishwasher. If the water pump fails, it can prevent the dishwasher from cleaning the bottom of the dishes.

Solution:

1. Check if the water pump is running by listening for a humming sound when the dishwasher is operating.
2. If you don’t hear a humming sound, the water pump may be faulty.
3. Call a qualified appliance repair technician to replace the water pump.

Low Water Pressure

Low water pressure can also cause a dishwasher to only clean the bottom of the dishes. If the water pressure is too low, the spray arms may not be able to rotate properly and the water may not reach the top of the dishwasher.

Solution:

1. Check the water pressure at your kitchen sink. If the water pressure is low, you may need to call a plumber to adjust the water pressure.
2. Ensure that the water supply line to the dishwasher is not kinked or blocked.

Dirty or Clogged Dishwasher Filter

The dishwasher filter is responsible for removing food particles and other debris from the water. If the filter becomes dirty or clogged, it can restrict the flow of water and prevent the dishwasher from cleaning the bottom of the dishes.

Solution:

1. Locate the dishwasher filter at the bottom of the dishwasher.
2. Remove the filter and clean it with hot water and a sponge.
3. Reinstall the filter.

Faulty Timer or Control Board

The timer or control board is responsible for controlling the dishwasher’s cycle. If the timer or control board fails, it can disrupt the dishwasher’s cycle and prevent it from cleaning the bottom of the dishes.

Solution:

1. Check if the dishwasher is running through a complete cycle. If the dishwasher stops prematurely, the timer or control board may be faulty.
2. Call a qualified appliance repair technician to diagnose and replace the faulty timer or control board.
