Top drawer of dishwasher has a loud pump noise while running

Pulled everything out of drawer thinking something was blocking flow to the pump but did not find anything. It started making excessive noise about 6 months ago and is getting louder. Unit is 8 years old.

Look for burrs on the botom impeller of the rotor. it requires no tools to check this. Take the wash arm and filter plate off, now rotate the motor rotor's base counter-clockwise and pull it out. Inspect the greay impeller closely for any nicks or burrs. If any are present, the impeller will make a LOT of noise. If it needs to be replaced, you can find them at fisher paykel parts, here is a link to the part you will need:

Very Loud Noise when dishwasher starts


It is likely the sound is coming from the rinse aid dispenser solenoid. (I am assuming you do not have a water softener unit on your dishwasher). Try to run the drawer on a Rinse cycle and see if the noise is still coming.

The top drawer started getting very loud - maybe the water pump? Now it looks as if no water is getting into the drawer so dishes remain dirty. The bottom works fine, and is not loud when running.


Yes it is likely the pump rotor is seized. I am assuming the water goes in to the drawer but does not get moved around by the washer arm. This is the function of the rotor. This rotor also acts as a drain pump in the drain cycle.

Have a rental property with F&P two draw dishwasher aprox five years old. Apparently bottom draw is holding water - what do you think?


Could be many reasons for the bottom drawer to hold water.

It could be leaky top drawer causing water to collect in the bottom drawer. Check if water collects when top drawer is running.

It could be blockage in the bottom drawer drainage which can be fixed by cleaning the filter plate and the drain sump. If the drain pump is not running during drain cycle then you will have to replace the drain pump motor.

I have a Fisher/Paykel dual drawer dishwasher and the top drawer now makes a loud grinding noise - appears to be coming from the front of the unit. Any thoughts? Any home-based solutions?


Remove dish rack, spray arm, remove filters, remove the rotor (under the spray arm) Check if the rotor itself is making any sound or not rotating freely when you turn the impeller on the top. Replace if needed, otherwise - carefully check for debris.

Middle and top spinners do not spin The pump is pushing water up the back delivery tube. There are no dishes in the unit and I was able to trick the door into thinking it was closed so I could watch what...


Hi,
Remove each spray arm and check it is clear of food particlesat the jets. The next problem may occour at the rotating joint . If the seal is not good, you can loose a lot of water out of this point.. If both of these seem reasonable, then yes the circulation pump may need checking. First check for any debris in the impeller, and that it is not worn or damaged, and that it is attached to the motor or the coupling is still good. If these are ok, then the motors='s capacitor may be faulty - causing it to buzz more than normal usually, and it looses efficiency, getting hot in the process.

One of these should solve the problem !

Loud Humming noise every time we run the dishwasher


Hi, I had this exact same problem. In my situation it turned out to be the pump that pumps out all of the used water. It was rubbing up against the floor so that every time it turned on it made a loud vibrating sound. I just reached under the washer and put a piece of rubber between it and the floor and it solved the problem.

good luck!

I saw this post because I am considering buying the same model you have. Other than the noise problem you have, what do you think of it?

Loud noise


My Dishwasher had the same loud Grinding Noise.
It was a piece of a plastic fork lodged behind the macerator blade.
This is at the suction to the pump just under the strainer. check this out first before you pull everything apart. You should be able to get to it by taking the lower arm off and pulling the strainer out. Hope this helps.

Dishwasher Dilema


You need to remove the bottom drawer and dry out the water with towels and a hair dryer when this is done it should operate normally. most likely when you pulled out the drawer the water sloshed back and out of the drawer making the dishdrawer think it was flodding turning on all drain pumps. If you look at the back of the drawer about two inches from the floor you will see an oval hole off center to the right. That is where the water got out.

Dishwasher Making Loud High Pitched Noise.


A loud high pitch whine while running the dishwasher means that there is something caught in the chopper assembly. To get to the chopper assembly you need to take the racks out and take the pump apart from the inside of the dishwasher. The chopper assembly looks like a metal grate with holes in it. And it might not even be stuck in the grate but somewhere in the pump area due to the water being pumped out, so the best idea is to take the whole thing apart and clean everywhere. However I do not recommend doing this unless you are completely certain you will remember where the screws and gaskets go, otherwise you risk damaging your pump or house from a leak or improper installation. You have been warned.
