Preliminary Steps Before Troubleshooting

Here are some preliminary steps…

Disconnect the Power Source

Prior to carrying out any kind of troubleshooting on your dishwasher, it’s crucial to disconnect it from the power source. This will safeguard you from electric shocks and other potential hazards.

Typically, you can unplug the unit from the electrical outlet. If it’s hardwired, you may need to turn off the circuit breaker that supplies electricity to the dishwasher.

Safety Gear

Don’t underestimate the importance of wearing proper safety gear when working with appliances. Gloves will offer you protection against sharp edges and possibly corrosive cleaning agents, while goggles will protect your eyes from any splashback from cleaning products or debris.

Inspecting the Drain Hose

Here’s how to inspect the hose…

Locate the Drain Hose

The drain hose is generally attached to the drain pump, situated at the base of the dishwasher. In most models, you’ll need to remove the lower kickplate to access it. The kickplate is typically attached with screws and can be easily removed using a screwdriver.

Detach the Hose

Once you’ve located the drain hose, use pliers to detach it from its connector. This usually involves loosening a hose clamp that holds the hose in place. Make sure to have a bucket or towel ready to catch any residual water that may leak out.


Closely inspect the hose for any visible blockages like food particles, grease, or small objects. You may use a long flexible brush to clear out any obstructions. It’s advisable to also check the hose for any kinks that might be preventing the water from draining out.

Test for Blockages

If the hose looks clear but you suspect a deeper blockage, you can run water through it. If the water doesn’t flow freely, then it’s confirmed that there’s a blockage. In such cases, you may consider replacing the hose altogether.

Reattach the Hose

Once you’ve cleared any blockages or made necessary replacements, it’s time to reattach the hose. Use the pliers to tighten the hose clamp securely, ensuring a snug fit.

Run a Test Cycle

After you’ve reassembled everything, plug the dishwasher back into its power source or turn the circuit breaker back on. Run a short wash cycle to test whether the issue has been resolved. Monitor the dishwasher to ensure that it drains properly.

Examining the Drain Pump

Here’s how to examine the pump…

Open the Dishwasher and Remove the Bottom Rack

Before you start investigating the drain pump, ensure the dishwasher is disconnected from its power source. Open the door and slide out the bottom rack to give yourself ample space to work. Put the rack aside in a safe place.

Locate the Drain Pump

The drain pump is usually located at the back of the dishwasher’s bottom area. Access to the drain pump might require removal of additional components, like a cover plate or shielding. Refer to your owner’s manual for specific guidance on how to access the drain pump for your model.

Check for Obstructions

Using a flashlight for better visibility, look for any obstructions that may be blocking the pump. This could be food particles, broken glass, or other debris. Remove any obstructions carefully, using tweezers or needle-nose pliers if necessary.

Signs of Wear and Tear

Inspect the pump for visible signs of wear and tear, such as cracks, leaks, or unusual noises when running. Damaged impeller blades inside the pump could also prevent it from functioning properly.

Consider Replacement

If the pump shows visible signs of damage, it may need to be replaced. Drain pumps can often be ordered directly from the manufacturer or through appliance parts retailers.

Replacement is usually straightforward but can vary in complexity depending on your dishwasher model. Follow the instructions in your owner’s manual and use appropriate tools for the job.

When to Consult a Professional

If you’ve diligently followed all the steps mentioned above for troubleshooting your dishwasher and yet the issue persists, the underlying problem could be more complex and may require professional attention.

Qualified technicians have the experience and tools to diagnose and repair issues that may not be evident to the untrained eye. They can also run specialized diagnostic tests that can pinpoint the issue more accurately.
