My Fisher & Paykel Dishwasher Is Not Draining

Updated February 21, 2017

Fisher & Paykel, headquartered in East Tamaki, New Zealand, manufactures and sells consumer appliances worldwide. The company specialises in drawer dishwashers, including single and double drawer models. A common problem with Fisher & Paykel dishwashers is that water can get caught in the tub and won't drain out. You can fix this problem on your own, saving you money on technician's fees.

Drainage Hose/Filters

If your Fisher & Paykel dishwasher is not draining, see if the drainage hose is kinked. The drainage hose is located on the rear of the dishwasher. Straighten the hose if it is kinked. Remove the hose to see if it's clogged. If it is, clean it out with a plastic utensil. Clean out the air gap if you have one installed. The air gap is located near the sink. If you don't have an air gap installed, install a high drain loop. Take the drainage hose and attach it to the underside of your counter top. This keeps water from the sink entering the dishwasher tub.

Non-return Valve

Fisher & Paykel dishwashers have non-return valves. This valve prevents water from re-entering the tub when it's draining out. If the valve isn't working properly, it can get stuck closed. See if the valve is clogged and clean it out with a plastic utensil. If the valve still won't operate properly, order a new one from an authorised Fisher & Paykel parts dealer since it's difficult to fix this component.


The pump is the component responsible for moving water into the drain. If it's not working properly, water won't drain from your dishwasher. Remove the spray arm, spray arm support and bottom rack from the dishwasher and examine the pump. It can get clogged with food and debris, including glass and plastic. Clean out the pump with a toothpick. See if any of the parts on the pump are broken, such as the pump impeller. Order a new pump since it's difficult to repair the pump.

Additional Problems

If you have a food waste disposer connected to your dishwasher, run it to clear any food caught in it. If you just installed the disposer, remove the knockout plug. Check the motor if you have not used the dishwasher in a long time. Disconnect the dishwasher from the power supply and try turning the motor by hand. If it doesn't turn freely after a few seconds, replace it since it's difficult to fix. Run your dishwasher at least once a week to prevent the motor from sticking.
