How to Keep Your Fisher & Paykel Dishwasher Clean and Running Well

What Fisher & Paykel Dishwashers Need to Stay Fresh

Fisher & Paykel dishwashers are built to handle heavy use, but they collect food particles, mineral deposits, and grease just like any other model. A clean dishwasher runs more efficiently, dries dishes better, and lasts longer. The good news is that Fisher & Paykel machines are straightforward to maintain—most of the work involves a monthly deep clean and a few quick weekly checks.

Your dishwasher has three main areas that need attention: the filter basket (which traps food), the spray arms (which distribute water), and the interior walls and door seals (which trap moisture and odors). Neglecting any of these leads to poor drying, spots on dishes, and musty smells that spread to your kitchen.

Key Takeaways

• Empty and rinse the filter basket weekly, and soak it monthly in hot water with white vinegar to dissolve mineral buildup.
• Check spray arm holes monthly and clear any blockages with a toothpick or small wire to restore water pressure.
• Wipe the door gasket and interior walls with a damp cloth every two weeks to prevent mold and odors.
• Run a cleaning cycle with white vinegar or a commercial dishwasher cleaner once a month to dissolve grease and mineral deposits throughout the machine.
• Leave the door slightly open after each cycle to allow moisture to escape and prevent mildew growth.

Cleaning the Filter Basket and Drain Area

The filter basket sits at the bottom of your Fisher & Paykel dishwasher and catches food scraps before they clog the drain. After every load, pull out the basket and rinse it under running water. Use your fingers or a soft brush to dislodge stuck particles. This takes less than a minute and prevents buildup that hardens over time.

Once a month, soak the filter basket in a sink filled with hot water and one cup of white vinegar for 15 to 20 minutes. Vinegar dissolves the mineral scale that accumulates from hard water and soap residue. After soaking, scrub gently with an old toothbrush and rinse thoroughly before replacing it. If your water is very hard, repeat this monthly soak every two weeks instead.

While the basket is out, look down into the drain opening. If you see standing water or smell sourness, the drain line may be partially blocked. Pour one cup of white vinegar followed by one cup of hot water down the drain opening and let it sit for 30 minutes. This dissolves grease and biofilm without damaging the machine. Never use a wire or tool to poke the drain—you risk puncturing internal lines.

Clearing Spray Arm Blockages

Fisher & Paykel dishwashers have one or two spray arms that rotate and spray water across the dishes. If water cannot flow through the small holes in these arms, dishes come out dirty and wet. Check the spray arms once a month by removing them (most models twist counterclockwise) and holding them up to the light. You should see clear holes all the way through.

If holes are blocked by mineral deposits or food particles, soak the arm in hot vinegar for 15 minutes, then use a toothpick or straightened paperclip to gently clear each hole. Push from the inside outward so you dislodge the blockage rather than driving it deeper. Rinse under running water and reinstall. Do not use a wire that is thicker than a toothpick—you can enlarge the holes and change the spray pattern.

Wiping Down the Door Gasket and Interior Walls

The rubber gasket that seals the door is a magnet for mold and mildew because it stays damp between cycles. Every two weeks, wipe it with a damp cloth and a small amount of white vinegar. Pay special attention to the folds and crevices where moisture hides. If you see black spots or smell mustiness, the gasket needs cleaning more often—switch to weekly wipes.

The interior walls and corners of your Fisher & Paykel also collect grease and soap scum. After you empty the dishwasher, take a damp cloth and wipe the top edges, the sides, and the bottom corners. This takes two minutes and removes the film that traps odors. If the interior smells sour or musty despite regular wiping, run a cleaning cycle (see next section) to reach areas the cloth cannot access.

Running a Monthly Cleaning Cycle

Once a month, run your Fisher & Paykel through a cleaning cycle with no dishes inside. You have two options: white vinegar or a commercial dishwasher cleaner. White vinegar is cheaper and works well for most households. Pour two cups of white vinegar into a bowl and place it on the top rack, then run a normal or hot cycle. The vinegar circulates through the spray arms, filter, and drain, dissolving grease and mineral deposits.

If your water is very hard or your dishwasher has stubborn stains, use a commercial cleaner like Finish Dishwasher Cleaner or Affresh. Follow the product instructions—most require you to place the bottle or packet in the bottom of the empty tub and run a full cycle. These products are stronger than vinegar and break down heavy mineral buildup faster. Use them every two months if your water hardness is high, or every three months for soft water.

Never mix vinegar and commercial cleaners in the same cycle. Run one, wait until the cycle finishes, then run the other if needed. Mixing can create fumes and reduce the effectiveness of both products.

Preventing Odors and Moisture Buildup

The most common complaint about dishwashers is a musty or sour smell that develops even after cleaning. This happens because moisture gets trapped inside after each cycle. The simplest fix is to leave the door slightly ajar (about two inches) after the cycle ends and the dishes are cool. This allows air to circulate and moisture to evaporate. If you have young children or pets, prop the door open with a wooden spoon so it cannot swing shut unexpectedly.

If you prefer to close the door, run a short heat-dry cycle at the end of your wash. This evaporates most of the standing water. Check your Fisher & Paykel manual for the exact button or setting—some models call it "Heat Dry," others "Extra Dry," and some have a separate drying option. Heat-dry uses more energy but keeps the interior completely dry between uses.

Store an open box of baking soda on the bottom rack when the dishwasher is not in use. Baking soda absorbs odors and moisture. Replace the box every three months or whenever it becomes damp. This is especially helpful if your dishwasher sits unused for more than a few days.

Organizing Your Dishwasher to Reduce Cleaning Work

How you load your Fisher & Paykel affects how clean it stays. Rinse large food scraps off dishes before loading—you do not need to wash them, just remove chunks of food. This reduces the amount of debris that reaches the filter basket and drain. Avoid loading greasy pans directly on top of the filter basket; instead, place them on the sides or top rack so grease drains away from the filter area.

Do not overload the dishwasher. Cramming too many dishes blocks the spray arms and prevents water from reaching all surfaces. Dishes also trap moisture against the interior walls. A moderately loaded machine cleans better, dries faster, and stays fresher between cycles. If you run the dishwasher twice a week instead of once, you will notice fewer odors and less buildup.

Frequently Asked Questions

Why does my Fisher & Paykel smell like rotten eggs?

That smell comes from bacteria and biofilm in the drain or filter basket. Empty and rinse the filter basket, then pour one cup of white vinegar down the drain and let it sit for 30 minutes. Run a hot cycle with the vinegar bowl on the top rack. If the smell returns within a week, the drain line may need professional cleaning—contact a Fisher & Paykel service center.

Can I use bleach to clean the inside of my dishwasher?

No. Bleach damages the rubber gasket and internal seals, and it can corrode stainless steel. Use white vinegar or a commercial dishwasher cleaner instead. Both are safe for all Fisher & Paykel materials and work just as well.

How often should I replace the filter basket?

The filter basket lasts many years if you rinse it weekly and soak it monthly. Replace it only if it cracks, warps, or the mesh tears. You can order a replacement from Fisher & Paykel or a parts supplier using your model number, which is on a sticker inside the door frame.

What should I do if water is not spraying from the arms?

First, check that the spray arms are installed correctly and rotate freely by hand. Then remove them and soak in hot vinegar for 15 minutes to clear mineral blockages. If water still does not spray after reinstalling, the pump may be failing—contact a service technician.

Is it safe to leave the dishwasher door open overnight?

Yes. Leaving the door open for a few hours after each cycle is one of the best ways to prevent odors and mold. If you leave it open overnight, make sure children and pets cannot trip on it or reach inside.
