Let’s look at each of these in more detail;
Fisher & Paykel Dishwasher Fails To Start
The first thing to check here is whether the dishwasher is receiving power. Check the plug is fully inserted into the socket, the socket works and is switched on, the circuit breaker is switched on and the power cord is not frayed or loose.
If all of the above are OK check;
- The Door & Drawer Are Latched Correctly
If both the door and the drawer are not latched correctly, the dishwasher will not start.
- The Key Lock/Child Lock Are Deactivated
The key lock and the child lock both disable the control panel which will stop the dishwasher from starting. Deactivate both of these before attempting to start the appliance.
- The Water Supply
If the water supply has been cut to the dishwasher for any reason, it will not start. Check that your home has water, and that the tap and inlet hose are able to allow water to flow freely.
- The Strainer Is Clogged
If the strainer is clogged due to excess dirt, this can block the inlet hose and prevent the dishwasher from starting.
- The Start Button Has Been Firmly Pressed
The dishwasher will not start unless the “start/pause” button is pressed firmly. Ensure you give it a firm press.
Dishwasher Beeps But Won’t Start
If your Fisher & Paykel dishwasher beeps and won’t start it is usually caused by one of the following;
- Key Lock/Child Lock Activated
One of the ways the dishwasher notifies you that the key lock or child lock is activated is by beeping. The appliance will not start when either of these has been activated. To deactivate, simply press and hold the key lock or child lock switch.
- Door Not closed Properly
If the door is not closed properly, maybe because of an obstruction, the dishwasher will beep but won’t start.
- Door Unaligned
The dishwasher will beep and fail to start if the door or the pyrex glass is unaligned. You will need to adjust it and press start again.
Fisher & Paykel Dishwasher Beeps & Flashes
If your Fisher & Paykel dishwasher beeps and flashes it typically indicates a fault and is often accompanied with an error code.
See below for more information on Fisher & Paykel dishwasher error codes.
Dishdrawer Controls Not Responding
If the dishdrawer buttons on your Fisher & Paykel dishwasher fail to respond it will most likely be caused by;
- Key Lock/Child Lock Activated
Both the key lock and the child lock render the control panel unresponsive. You will need to deactivate either, or both of these before the dishdrawer controls will work again.
- Control Panel Wet
Just like your smartphone or tablet, if the control panel is wet or you try to use it with wet hands, it will not work. To solve this, dry your hands and the control panel.
- Drawer Not Fully Latched
If the door is not fully latched, the buttons will not respond. Ensure the door is closed and latched correctly then try again.
- No Power
If there is no power, none of the buttons or controls will respond. Ensure the power supply is working and that the plug, socket, circuit breaker etc are all switched on and working correctly.
Fisher & Paykel Dishwasher Fails To Drain
If your dishwasher fails to drain all of the water away it can be disastrous and lead to flooding in your kitchen. This could be caused by:
- Clogged Filter
The filter traps all of the food and dirt particles and prevents them from getting back onto the now clean dishes. If the filter becomes clogged, the wastewater can become trapped also and not flow away as it should. You will need to clean the filter and then make cleaning the filter a regular part of your cleaning schedule to prevent this from happening again.
- Blocked Drain Hose
In some cases, the drain hose can become twisted or kinked which can lead to a blockage which will prevent the wastewater from leaving the appliance. Straighten the hose and remove any blockages to solve this issue.
- Twisted Or Incorrectly Fitted Inlet Hose
If the inlet hose is twisted or fitted incorrectly or if it is loose, it can prevent the appliance from draining properly.
- Blocked Rotor
In some cases, food and dirt can accumulate around the rotor which can prevent drainage. You will need to clean the rotor to solve this issue.
- Jammed Pump
If the pump has become jammed with food and dirt it will prevent the dishwasher from draining. The pump will need to be cleaned and as this part is hard to access, we recommend contacting a technician to solve this.
Dishes Don’t Clean
If your dishes are still dirty after the dishwasher has completed the wash cycle, it is usually caused by;
- Wrong Cycle Selected
Your Fisher & Paykel dishwasher has many different wash programmes and cycles to suit various dishes. If you select the wrong cycle, your dishes might not clean properly.
- Dishes Not Scraped Before Loading
If you fail to clear excessive amounts of food or dried on foods, your dishwasher might not be able to clean them sufficiently.
- Dishes Incorrectly Loaded
The dishes will not clean if they are loaded incorrectly. Ensure none of the dishes overlap and block each other or are unevenly loaded.
- Wrong Detergent Used
Using too much detergent or an inferior quality detergent can lead to the production of excessive amounts of foam or soap suds. This can prevent the dishes from cleaning properly. There could also be an issue if the detergent was placed in the wrong compartment, ensure you use the correct compartment for your detergent.
- Clogged Filter
If the filter is clogged, it will prevent the dishes from cleaning properly. Ensure the filter is cleaned regularly to prevent this from being a problem.
- Spray Arm Blocked
If the spray arm has become clogged either with food or limescale buildup, it will prevent the dishes from getting clean. Ensure there is nothing clogging the spray arms at all. You can use a toothbrush to clean the spray arm nozzles or a toothpick if calcium buildup is the problem.
- Insufficient Rinse Aid
If there is insufficient rinse aid, the dishwasher will be unable to clean dishes properly. Ensure the rinse aid dispenser is topped up before each use.
Fisher & Paykel Dishwasher Not Filling With Water
Your dishwasher needs enough water to soak all of the dishes to get them clean. If it isn’t getting water, it will usually be because;
- The Water Supply Has Failed
If the water supply to your home has been stopped due to a leak or some other emergency, you will need to get it running properly before you can use your dishwasher.
- The Inlet Hose Is Faulty
Sometimes, the inlet hose can become twisted or kinked, this can prevent enough water entering your appliance. This will prevent it from filling with water. You will need to straighten the hose and ensure the tap is fully open to allow enough water into your dishwasher to clean your dishes.
- The Spray Arms Are Blocked Or Misaligned
If there is a blockage in the spray arm, it can prevent enough water from entering your dishwasher. Check the nozzles on the spray arms for blockages from food or calcium buildup and clean as necessary. Also, if the spray arm has become misaligned this can also prevent enough water from entering the appliance.
Water Not Heating
There are several reasons why your dishwasher fails to heat the water which include;
- Wrong Programme Selected
Some wash programmes like Eco or Gentle/Delicate save energy and take extra time to heat up.
- Dirty Filter
In some cases, a blocked or dirty filter can prevent the appliance from heating up. Clean the filter and prevent this from happening again by making the filter a regular part of your cleaning schedule.
- Power Supply Fault
If the appliance doesn’t receive any power, the water cannot heat up. Ensure the power supply is working correctly.
- Poor Quality Detergent
Using inferior detergent can cause excess foaming and soap suds which can prevent the water from heating sufficiently. You should always use the best quality detergent that you can.
- Faulty Heating Element
If the heating element develops a fault, your appliance will fail to heat up. You can test the heating element using a multimeter and if it fails a continuity test, you will need to replace it.
Fisher & Paykel Dishwasher Not Drying Dishes
Dishes often come out of a dishwasher slightly damp, but if they are excessively wet it could be because;
- A Lack Of Rinse Aid
Rinse aid ensures that dishes dry and are streak free. If there is insufficient rinse aid the opposite could be the case. Always ensure that the rinse aid dispenser is topped up.
- The Wrong Cycle Selected
If you select the wrong cycle, like the Gentle/Delicate cycle for instance, this can prevent the dishes from drying properly.
- Eco Mode Activated
The Eco wash mode has a shorter drying cycle which can mean the dishes don’t have time to dry properly.
- Incorrectly Loaded Dishes
Overloading the dishwasher with too many dishes or overcrowding dishes can also prevent them from drying properly.
- Dishes Removed Too Soon
Unloading dishes too early from the appliance can result in them still being wet. This can also happen if you leave them in the dishwasher for too long. The dishes should be removed around 2 hours after the programme has finished.
