Why is Your Roper Dishwasher Not Draining?

1. The drain pump

One possible reason for your Roper dishwasher not draining could be an issue with the drain pump.

The drain pump uses an impeller to force water through the drain hose.

If the drain pump motor is not working, your dishwasher won’t drain.

You can determine if the drain pump is defective by checking the pump motor for continuity with a multimeter.

2. Clogged filter

Another reason for a malfunctioning Roper dishwasher is a clogged filter.

A dirty filter can prevent the water from draining and result in dirty dishes.

To resolve this issue, remove the filter according to the owner’s manual and thoroughly rinse it under hot water.

Replace the filter if it is damaged or cannot be effectively cleaned.

3. Dead control panel or user interface control

A dead control panel or user interface control could also lead to a dishwasher not draining.

Suppose the control panel or user interface control is not functioning correctly.

In that case, your dishwasher might stop mid-cycle and fail to continue the wash and drain cycle, leaving your dishes dirty.

4. Damaged door latch

Your dishwasher might not be draining due to a damaged door latch.

A broken door latch is an essential safety feature that will prevent your dishwasher from running the wash and drain cycles.

If the door latch is malfunctioning, the dishwasher may not detect the door is closed; thus, draining is hindered.

5. Tripped thermal fuse

While it’s less common, a tripped thermal fuse can cause the dishwasher to stop functioning altogether, causing the dishwasher to terminate mid-cycle and not drain.

Test the thermal fuse for continuity to see if it requires replacement.

6. Food particles and debris

Finally, the dishwasher might not drain due to food particles and debris blocking the exit at the drain hose.

Regularly clean the drain hose to prevent build-up and ensure smooth water flow during the wash and drain cycles.

Following these tips will help you identify and fix the issue causing your Roper dishwasher not to drain properly and improve the overall performance of your appliance.

How to Fix a Roper Dishwasher Not Draining

Here are the best ways to fix a Roper dishwasher not draining.

1. Check the Drain Hose

First, ensure that the drain hose is not clogged or kinked.

To do this, disconnect the hose from the dishwasher and sink, then use a long brush or a straightened coat hanger to remove any debris.

If the drain hose is damaged or cannot be cleared, it may need to be replaced.

2. Inspect the Dishwasher Drain Pump

The dishwasher drain pump uses an impeller to force water through the drain hose.

If the drain pump motor is not working, the dishwasher won’t drain.

Check the motor for continuity using a multimeter to determine if the drain pump is defective.

If the pump motor is indeed faulty, you may need a Dishwasher Drain Pump Compatible replacement, which can be found at Appliance Parts Pros or other appliance repair service providers.

3. Clean the Filters

Your dishwasher has coarse and fine filters that can get clogged, leading to poor water flow and washability.

Remove the filters and wash them with soap, warm water, and a brush.

If the filters cannot be cleaned effectively or if they are damaged, they will need to be replaced.

4. Examine the Check Valve

A broken check valve can cause dishwasher leaks and prevent proper draining.

You can find replacement check valves from John Home Appliance or Advance Appliance.

Consult your dishwasher’s repair guides for instructions on how to replace the check valve, or consider hiring an appliance technician to handle the task.

How to Prevent the Problem

To prevent a Roper dishwasher from not draining, it’s essential to maintain and care for it properly.

By keeping an eye on several key elements, you can ensure your dishwasher continues to work efficiently and effectively.

1. Maintain the Dishwasher Filters

Regularly cleaning and maintaining the dishwasher filters will help to prevent clogging and build-up that can hinder the draining process.

Remove the filters, rinse them under running water, and scrub gently with a soft brush to remove any debris.

Reinstall them correctly to maintain optimal performance.

2. Check the Dishwasher Motor

Be aware of the dishwasher motor’s condition, as a worn or faulty motor can stop the dishwasher from draining properly.

If you notice any strange noises or a decline in performance, it’s best to have the motor inspected by a professional to avoid further complications.

3. Inspect the Hose Connections

It’s crucial to inspect the hose connections of your dishwasher periodically.

Ensure that the drain hose is securely connected to the sink or garbage disposal and that there are no kinks or obstructions in the hose.

Replace any damaged or worn hoses to prevent leaks and ensure proper draining.

4. Clean the Dishwasher Door Gasket

The dishwasher door gasket helps maintain a watertight seal during operation.

Regularly inspect and clean the gasket to ensure its longevity and prevent water leaks.

If you notice any cracks or damage, replace the gasket as needed.

5. Use High-Quality Dishwasher Detergent and Cleaner

Using a high-quality dishwasher detergent and regular dishwasher cleaner can help to prevent build-up and residue, which can cause the dishwasher not to drain.

Follow the manufacturer’s instructions on dosage and frequency for the best results.

5. Avoid Overloading the Dishwasher

Overloading the dishwasher with too many dishes or improperly arranging them may result in poor drainage.

Allow enough space between each item to ensure thorough cleaning and proper water flow.

Utilize the dishwasher racks and holders, such as the dishwasher detergent holder, to maximize efficiency.

6. Check the Dishwasher Breaker

Monitor the dishwasher breaker to avoid power interruptions that may result in incomplete draining.

Ensure the breaker is functioning correctly and not tripping during the dishwasher’s operation.

By following these suggestions and keeping your dishwasher well-maintained, you can prevent drainage issues and enjoy clean, dry dishes every time you run your appliance.
