Dishwasher Not Doing Rinse Cycle: A Guide to Troubleshooting

If you’ve noticed your dishwasher not doing rinse cycles, you’re probably frustrated and confused. But don’t worry, this issue is common and solvable. In this guide, we’ll walk you through every step to identify the problem and fix it.

Identifying the Issue

Before diving into solutions, it’s crucial to determine why your dishwasher isn’t completing its rinse cycle. It could be a range of issues, from blockages to faulty parts.

Check for Blockages

One common reason for a dishwasher not doing rinse cycles is a blockage in the spray arm or filter. A blockage can hinder the water flow needed to rinse your dishes, leading to incomplete or ineffective cleaning.

Here are the detailed steps to check for any blockages:

Turn Off and Unplug

Before you begin, it’s imperative to ensure your safety. Turn off your dishwasher using the power button or control knob.

Next, unplug it from the electrical outlet. This step is crucial to avoid any electric shocks or accidental activation of the machine while you’re working on it.

Open the Dishwasher

After unplugging the dishwasher, open its door fully. You’ll usually find two racks: an upper rack for glasses and smaller items, and a lower rack for larger items like pots and pans.

For this task, you’ll need to focus on the lower rack. Pull it out completely and set it aside. This gives you full access to the spray arm and the filter.

Inspect the Spray Arm

The spray arm is a critical component for rinsing your dishes. It’s usually a flat, spinning blade located below the lower rack. Clogs in the spray arm holes can prevent water from spraying out, disrupting the rinse cycle.

Locate the Spray Arm: It’s typically at the bottom of the dishwasher, a spinning arm with multiple holes.

Remove the Spray Arm: Some models allow for easy removal by unscrewing a nut or simply lifting it off. Refer to your dishwasher’s manual for specific instructions.

Check for Obstructions: Look through each hole in the spray arm for visible food particles or other debris. Sometimes, you may need a flashlight for a better view.

Clean the Spray Arm: If you find any clogs, use a toothpick or a piece of thin wire to carefully remove the debris. After that, run the spray arm under tap water to clear out any remaining particles.

Reinstall the Spray Arm: Place the cleaned spray arm back into its position and secure it as per your model’s guidelines.

Check the Filter

The filter is another common area for blockages. It’s usually located at the bottom center of the dishwasher, underneath the spray arm.

Locate the Filter: Look for a cylindrical or round component, often made of plastic with a metal mesh.

Remove the Filter: Typically, you can twist it counter-clockwise or unlock some clips to remove it. Again, consult your manual for specific steps.

Inspect the Filter: Check for food particles, pieces of broken glass, or any other debris.

Clean the Filter: Hold the filter under running tap water and use a soft brush to scrub off any debris.

Reinstall the Filter: Once cleaned, place the filter back into its housing. Secure it as per your dishwasher’s instructions.

Examine the Water Inlet Valve

If you’ve ruled out blockages as the reason for your dishwasher not doing rinse cycles, the next step is to examine the water inlet valve.

This valve controls the flow of water into your dishwasher and a defective one could prevent the rinse cycle from occurring. Here’s a detailed walkthrough on how to check this crucial component:

Locate the Valve

The water inlet valve is typically located at the back of the dishwasher, obscured by a panel. It’s the point where the water supply hose connects to your dishwasher, often made of plastic or metal.

Unplug the Dishwasher: Just like before, ensure the dishwasher is both turned off and unplugged for safety.

Access the Rear Panel: Most dishwashers have a rear or bottom panel that you’ll need to remove. This usually involves unscrewing a few screws, so you might need a screwdriver.

Identify the Valve: Look for a part where the water hose from your wall connects to the dishwasher. This is your water inlet valve.

Test the Valve

Now that you’ve located the water inlet valve, the next step is to test its functionality. For this, you’ll need a multimeter.

Turn Off Water Supply: Locate the water supply knob on your wall (usually near the dishwasher or under the sink) and turn it off to stop water flow to the appliance.

Disconnect the Hose: Carefully unscrew the water supply hose from the valve. Have a towel ready, as some residual water may spill out.

Unplug the electrical connectors: Unplug the electrical connectors from the inlet valve assembly (make sure to note where each one goes).

Set Your Multimeter: Ensure your multimeter is set to test resistance (measured in ohms). If you’re unfamiliar with using a multimeter, consult its manual for specifics.

Test for Continuity: Place the multimeter probes on the terminals of the valve. A reading that hovers around infinity signifies that there’s no continuity, and thus the valve is faulty.

Interpret the Results: If the multimeter confirms the absence of continuity, the valve is defective and needs to be replaced. If it shows continuity, then the issue likely lies elsewhere.

Please note that specific steps to access the inlet valve and specific inlet valve readings will vary widely depending on the model of your appliance. Check your manual for more information.


If you discover that the water inlet valve is indeed defective, you’ll need to replace it.

While this can be a DIY project if you’re comfortable with appliances, it’s often best to hire a qualified technician for such tasks, especially if you’re not experienced in handling electrical or plumbing components.

Inspect the Timer and Control Panel

If you’ve examined the water inlet valve and found it to be in good condition, yet your dishwasher is still not doing the rinse cycle, then it’s worth taking a look at the timer and control panel.

These components dictate the cycle times and functionalities of your dishwasher, and any defects could interrupt the rinse cycle. Here’s how to inspect them:

Access the Control Panel

The control panel is often located on the door or the upper part of the dishwasher’s front side. Gaining access to it usually requires removing the front panel of the dishwasher.

Turn Off and Unplug the Dishwasher: As always, safety first. Make sure your dishwasher is both off and unplugged from the electrical outlet.

Find the Screws: The front panel is typically secured with screws around the edges or underneath. Some models may have screws inside the door. Locate these screws.

Unscrew the Panel: Using a screwdriver, carefully unscrew and keep track of all the screws. You’ll need to put them back later.

Remove the Front Panel: Gently lift or slide off the front panel to reveal the control panel.

Inspect the Timer

The timer is an integral part of the control panel and usually resembles a round dial or a digital component, depending on your dishwasher’s model.

Locate the Timer: It’s often near the cycle selector or digital display.

Physical Inspection: Look for any burnt areas, corroded terminals, or other signs of damage on or around the timer. Sometimes, damages are not visible, so be thorough in your inspection.

Smell Test: Occasionally, electrical components give off a burnt smell when they fail. Sniff around the timer for any such odors.

Multimeter Test: If your model has a mechanical timer, you can use a multimeter to check for electrical continuity, similar to the water inlet valve. Check your manual for the appropriate readings.

If there’s no continuity or the resistance is inconsistent with what’s expected, the timer is likely defective.
