Why Is Your Fisher and Paykel Dishwasher Not Draining?

There could be several reasons why your Fisher and Paykel dishwasher is not draining properly.

Let’s explore some of the most common causes, providing you with information to help you identify and address the issue.

1. Clogged Dishwasher Filter

A clogged dishwasher filter can lead to your appliance not draining correctly.

The filter is located at the bottom of your dishwasher and is responsible for trapping food particles and debris.

Over time, debris may accumulate and prevent water from properly draining.

Ensure that you check and clean the dishwasher filter regularly to prevent blockages.

2. Obstructed Drain Pump

If your Fisher and Paykel dishwasher’s drain pump is blocked, it can also cause drainage issues.

The pump is responsible for pushing the dirty water out of the dishwasher.

Inspect the drain pump for debris, such as food particles or foreign objects, that may obstruct its operation.

If you discover any obstructions, remove them carefully to restore proper function.

3. Kinked Drainage Hose

A kinked or damaged drainage hose can prevent water from flowing out of the dishwasher.

Inspect the drainage hose for bends, kinks, or damage, and ensure that it is properly connected to the sink drain.

If you find a kink in the hose, straighten it out to improve

Replace the hose if it is damaged.

4. Blocked Spray Arm Holes

The spray arm, responsible for distributing water during rinse cycles, can become clogged with food particles and residue.

This can cause insufficient water pressure and affect the dishwasher’s ability to drain.

Remove the spray arm and clean it thoroughly with hot water and a soft brush to clean the spray arm holes.

5. Improper Dish Loading

Loading your dishwasher improperly can also lead to incomplete drainage.

If dishes are tightly packed or stacked incorrectly, they may restrict water flow and prevent the dishwasher from draining effectively.

Load your dishes according to the manufacturer’s instructions to avoid overcrowding the dish drawer to avoid this issue.

6. Malfunctioning Pump Impeller

A broken or damaged pump impeller can prevent your Fisher and Paykel dishwasher from properly draining.

The impeller, located inside the drain pump, helps propel water through the drainage hose.

If the impeller is broken, you may need to have it replaced by a professional technician.

By addressing these potential causes, you can ensure your Fisher and Paykel dishwasher functions properly and drains effectively, providing you with clean and spotless dishes every time.

How to Fix a Fisher and Paykel Dishwasher Not Draining

If your Fisher and Paykel dishwasher is not draining properly, there could be a few potential causes.

The following troubleshooting steps can help you determine the issue and find a solution:

1. Check the Drain Hose

Ensure that the drain hose is not kinked, crushed, or blocked, as this can obstruct water flow and prevent proper draining.

Make sure the hose is correctly connected to the household drainage system or the sink drain.

2. Clean the Dish Drawer and Spray Arm

Remove any food particles or debris from the dish drawer and clean the spray arm to ensure water can flow freely through all drain holes.

This will help prevent blockages and improve the dishwasher’s overall performance.

3. Inspect and Clean the Dishwasher Filter

Dirty filters can reduce water flow and contribute to poor draining.

Remove the dishwasher filter and clean it thoroughly.

Ensure that no food particles or debris are blocking the filter or drain screens.

4. Examine the Drain Pump and Pump Impeller

The drain pump and its impeller are crucial in removing water from the dish drawer.

Check if the pump is functioning correctly and if the impeller is not blocked or damaged.

If the pump or impeller is faulty, you may need to replace them.

5. Look for Foreign Objects

Sometimes, a small object or item can become lodged in the dishwasher’s drain system, preventing water from draining properly.

Check the dishwasher for any foreign objects, such as small utensils or broken glass that may be blocking the drain.

6. Examine the Drain Loop Height

The drain loop height is crucial for enabling proper water flow during the rinse cycle.

Ensure the drain loop is positioned at the specified height according to the manufacturer’s instructions.

How to Prevent the Problem

To prevent your Fisher & Paykel dishwasher from not draining, follow these steps:

1. Check Drain Hose

Ensure the drain hose is not kinked, clogged, or damaged.

A blocked drain hose will prevent water from draining and lead to standing dirty water.

To clear a clogged drain hose, remove any visible debris and run hot water through it.

2. Clean the Drain Filter

Keep the dishwasher’s drain filter clean by regularly removing debris and food particles.

This will help maintain efficient water flow and prevent the accumulation of standing water in the dishwasher during the wash cycle.

3. Use the Correct Amount of Detergent

Avoid using excessive quantities of detergent.

Too much detergent will create excess foam, which can block the drain and cause issues with draining.

Refer to your Fisher & Paykel DishDrawer user manual for recommended amounts, and always follow the instructions on the detergent packaging.

4. Remove Excess Food

Before starting a wash cycle, scrape and rinse excess food off your dishes.

This will minimize the amount of food that can potentially block the drain system, improving the efficiency of your dishwasher.

5. Maintain Water Supply Pressure

Insufficient water supply pressure can affect the dishwasher’s draining abilities.

Ensure the household water supply is within the acceptable range for your Fisher & Paykel DishDrawer.

This typically means maintaining a water pressure of 0.3–1kPa (0.3-1 bar).

Additionally, check that your home’s water flow control devices, such as water softener filters, are working correctly.

6. Check for Foreign Objects

Inspect your dishwasher regularly for any foreign objects, such as utensils or food particles, that may have fallen into the drain area.

Remove any such obstructions to keep your drain system functioning properly.

7. Clean Dirty Filters

Filters are essential in preventing debris from entering the dishwasher’s drain system.

Regularly inspect and clean the filter system to maintain optimal performance.

8. Drain Hoses Loop Height

Make sure the drain hose loop height is at least 32 inches (80 cm) from the floor.

This configuration helps prevent backflow of water from the sink drain into the dishwasher.

By following these preventive measures, you can help keep your Fisher & Paykel dishwasher draining efficiently and avoid potential issues.
