Question about Whirlpool 24 in. DU1055XTPS Stainless Steel Built-in Dishwasher

1 Answer

Extremely noisy Whilrpool, sounds like electrical resistance.

My one year old Whirlpool DU1055XTPS makes a horrible noise when it is running. It seems to fill okay, and seems to enter wash cycle, but sometimes gets stuick in wash cycle, and other times goes through drain and rinse fine. The noise often changes pitch or frequency, but never really goes away. There are no error lights or warnings, and this noise does not sound like a buzzer, unless it is a seriously out of adjustment buzzer. There does not appear to be any parts or debris visible in the bottom of the tub, but I have not yet removed any parts. Noise seems to come from upper or middle left side, but there is a heat vent in the control panel, and maybe the sound is just resonating on that side because of this vent area? Please tell me what to look for, and how to fix this.
Thank you,

Mine did that when the end of the impeller broke off- the sound is the grinding of the remaining end of the impeller against the gears on the engaging end of the chopper. You'll need to get out your screwdriver to dig in deeper and find out if this is the problem.

Why is my whirlpool dishwasher making a loud noise during drain, wash and rinse cycles?

They can be complicated to re-assemble. Best solution is to video the procedure (if you have a video camera) during disassembly and make notes and diagrams to orient things properly and make sure the correct screws go back where they shoud. Takes more time, but you'll be glad you did, it will save you a lot of aggrevation in the long run.

Loud continuous buzzing noise while dishwasher is running

Hi hope you are well have you checked that the dishwasher isnt touching your units either side their should be a slight gap either side you will get this noise if it is touching anything at the sides or pressed up against something at the back if this is not the problem.
If it is making the noise through most of the wash cycle the the chances are it isnt going to be a pump on the way out the only other thing it could be is the motor that turns the spray arms around and it could be either the top or bottom usually if you can get to the motors you can oil the moving parts as sometimes thse get dry over time.
Try the first sollution first try moving the dishwasher a bit and then try it again if still noisy then the chances are one of the motors has got noisy on the spray arms it wouldnt be the pumps as the noise continues through most of the wash.
Some times just moving the dishwasher will recitfy the problem as the same happens with fridges and freezers if it has been knocked and is not level or is touching a unit you will get a slight vibrating noise so try moving it a bit.
Let us know how you get on

My LG 1415T1 sound horrible when running

Normally when one hears a continuous noise throughout the cycle, it is caused by the pump motor bearing having become wet due to a leaking seal. The roller bearing closest to the seal becomes rusted and then creates this awful noise. The pump impeller is a sealed unit so you will have to replace the pump.

Quiet partner 1 top rack does not get clean at all


I would suspect you have debris in the pump that is causing a pressure drop so the water is not spraying well in the upper arm.

Try this procedure to clean out the sump. Let me know if it helps.

Loud buzzing noise throu8ghout cycle. Sometimes washer sticks in wash mode

It appears your timer/main controller/CCU has failed in this instance.

For replacement parts - head on over to or and enter in your full model number for a full parts listing.
I recommend both sites because ...

FixYa has no affiliation with either site - I have been using and recommending them for years - trouble free.

PartSelect has a great schematic database for locating the part on your unit and great "testimonials" for each part that often times includes HOW-TO information.
RepairClinic has pictures of each part they sell and also a great how-to and troubleshooting for basic repairs.

If your unit has never been serviced - there should still be an original service manual enclosed in plastic taped to the inside of the shell.
In the service manual are Error codes, maintenance procedures, and troubleshooting steps you can follow.

Anything too complicated or beyond your scope should be handled by a professional.

If you think you want to tackle the repair - and have gotten stuck on a step - reply to your question and I will be glad to help you out.

Thanks for using FixYa - a 4 THUMBS rating is appreciated for answering your FREE question
