Fisher And Paykel Dishwasher Not Draining

A dishwasher that won't drain can quickly turn into a kitchen nightmare. If your Fisher & Paykel dishwasher is holding water, don't panic. Often, the issue is something you can resolve yourself, saving you the cost of a service call. Here's a practical guide to troubleshooting and fixing common drainage problems.
Initial Assessment
Before diving into complex solutions, take a quick look at the obvious. Is the dishwasher making any noises? If it sounds like the pump is running but no water is moving, that indicates a different problem than if the dishwasher is completely silent.
Check the drain hose. Is it kinked or bent sharply? A kink can restrict water flow. Also, ensure the drain hose is properly connected to the garbage disposal or sink drain.

Clearing the Drain Filter
The drain filter catches food particles and debris, preventing them from clogging the drain pump. A clogged filter is the most common reason for a Fisher & Paykel dishwasher not draining.
Finding the Filter
The filter is usually located at the bottom of the dishwasher's interior. On most Fisher & Paykel models, it will be a cylindrical component that you can unscrew or lift out.

Cleaning the Filter
- Remove the lower dish rack to access the filter.
- Unscrew or lift out the filter assembly. Some models have multiple parts to the filter, so pay attention to how they fit together.
- Rinse the filter thoroughly under running water. Use a soft brush (like an old toothbrush) to scrub away any stubborn food particles.
- Inspect the filter for any damage, such as cracks or tears. Replace the filter if damaged.
- Reassemble the filter and place it back into the dishwasher. Make sure it's securely in place.
Checking the Drain Pump
If the filter is clean but the dishwasher still won't drain, the next step is to check the drain pump. The drain pump is responsible for pushing the water out of the dishwasher.
Locating the Drain Pump
The location of the drain pump varies depending on the model, but it's generally located at the bottom of the dishwasher, behind the kickplate at the front. You might need a screwdriver to remove the kickplate.

Inspecting the Drain Pump
- Disconnect the power to the dishwasher. Locate the circuit breaker for the dishwasher and turn it off. This is crucial for your safety.
- Remove the kickplate at the bottom front of the dishwasher.
- Locate the drain pump. It will have wires connected to it and a hose attached.
- Carefully disconnect the hose from the drain pump. Be prepared for some water to spill out.
- Check the drain pump impeller (the small blades inside the pump) for any obstructions. Small objects like glass shards, seeds, or bits of plastic can get lodged in the impeller and prevent it from spinning.
- Use needle-nose pliers or tweezers to carefully remove any debris from the impeller.
- Manually spin the impeller to ensure it rotates freely. If it's stiff or makes a grinding noise, the pump may be damaged and need replacement.
- Reconnect the hose to the drain pump.
- Replace the kickplate.
- Turn the power back on to the dishwasher.
If the pump is humming but not pumping, it's likely jammed. If it's completely silent, it could be faulty.
Addressing a Clogged Drain Hose or Air Gap
Sometimes, the problem isn't within the dishwasher itself, but in the drain hose or air gap. The air gap is a small device located on the sink that prevents dirty water from flowing back into the dishwasher.

Checking the Drain Hose
- Disconnect the drain hose from the garbage disposal or sink drain.
- Check the hose for kinks or obstructions. Straighten any kinks.
- Blow through the hose to see if air passes freely. If not, there's likely a clog.
- Use a long, flexible brush (like a plumbing snake) to clear any blockages in the hose.
- Reattach the drain hose.
Cleaning the Air Gap
- Remove the air gap cover.
- Use a small brush or pipe cleaner to clean out any debris inside the air gap.
- Flush the air gap with water to ensure it's clear.
- Reassemble the air gap.
Dealing with a Clogged Garbage Disposal
If your dishwasher drains into the garbage disposal, a clogged disposal can prevent the dishwasher from draining properly.
Clearing the Garbage Disposal
- Make sure the garbage disposal is turned off.
- Check the disposal for any large objects that may be causing the clog. Remove any visible obstructions.
- Run cold water into the disposal while turning it on briefly.
- If the disposal is still clogged, try using a garbage disposal wrench to manually turn the blades and dislodge any stubborn debris.
- As a last resort, you can try using a mixture of baking soda and vinegar followed by hot water to break down the clog.
When to Call a Professional
If you've tried all of the above steps and your Fisher & Paykel dishwasher still won't drain, it's time to call a qualified appliance repair technician. There may be a more serious problem, such as a faulty drain pump motor or a problem with the dishwasher's control board.

Attempting to repair complex electrical or mechanical components yourself can be dangerous and may void your warranty.
Preventive Maintenance
Regular maintenance can help prevent drainage problems in the first place. Here are a few tips:
- Scrape food off dishes before loading them into the dishwasher.
- Clean the drain filter regularly (at least once a month).
- Run the garbage disposal regularly to prevent clogs.
- Avoid putting large or hard objects (like bones or fruit pits) down the garbage disposal.
Troubleshooting Checklist: Fisher & Paykel Dishwasher Not Draining
- Initial Assessment: Check for obvious kinks in the drain hose and unusual noises.
