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

1 Answer

Loud continuous buzzing noise while dishwasher is running

My Whirlpool DU1055XTPS makes a horrible contiuous buzzing noise through most of the wash cycle. Although it does change in pitch and frequency during drain, wash and fill, it never really goes away. It sounds like it is coming either from the control panel or the left side, but I cannot be sure. It does not sound like an obstruction in the pump or motor, but rather more like an electrical resistance sound. It does not sound like a warning buzzer, but maybe it could be one that is vibratign at an unusual frequency. There are no error lights, and the washer goes through all of its cycles appropriately, but the noise is defening. Please tell me what to look for or how to diagnose this problem.
Thank you,

    Hi Paul,
    Thanks so much for your prompt response. This does not sound or feel like a vibration noise at all. I do not beleive that it is related to the position of the unit, or rubbing against sides or back, although I will check these clearances. It is definaely a loud electrical buzzing, which sounds like an electrical resistance, like when an electrical motor is stuck but current is still trying to turn it.
    Please advise furthur. Is it possible to observe the components while it is running to try to isolate the source of the noise?

  • schmitt Nov 28, 2007

    Clearance appears to be fine, although moving the unit did seem to lessen the noise a bit. Both spray arms (top & bottom) rotate freely. Unit does fill fine (and there is no noise during the fill process), and does drain when "cancel & drain" is selected, and sometimes drains in usual cycle. At other times, machine sticks in wash cycle and does not advance to drain.
    The noise seems to start during the spray cycle, and now gradually gets louder and louder, but seems to lessen in the middle of spray cycle. Maybe it is still a clearance vibration issue?

  • schmitt Nov 28, 2007

    I am running it while we chat, and it seemed to quiet down when I moved it around a bit, but then just when I thought that it might be solved, it started buzzing again during the soray cycle, and I cannot stop or alter the sound by shaking or moving the unit, although the pitch does change by itself louder and softer whenI don't touch or shake it Weird problem?

  • schmitt Nov 28, 2007

    The noise has now gotten so loud that I cannot stand it. Shaking, moving or lifting the unit does not seem to change the sound at all.
    It is still in the spray wash cycle, and I can't tell if it is stuck here, so I have pressed "Cancel & drain", and it is pumping water out of the unit, but the noise is still incredibly loud, same volume and pitch as when in spray wash cycle which is why I believe that it is not related to side contact vibration, or any specific motor. Do the control circuits or timers ever buzz loudly. It has just finished canceleing and draining, and shut off complete silence. What can this be?

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

    Hi if all the water pumps are working ie filling and draining and their is no water settling in the bottom inside yours does it have water jets top and bottom if so check that these are free and easy to turn.

    I have come across the problem where limescale has built up in the jets and causing the noise because the pumps are working harder to get the water through if the problem deffinately isnt clearence and after you have moved the dishwasher and give it a try if it is still making the noise then i could be lime scale build up.

    check all jets are not blocked.

    Do you have the chance to take the back off and be able to listen exactly where the sound is coming from if you can do this this might give you and me a better idea where the sound is coming from.

    Whilst waiting for your next post i will look for a user manuall and repair manuall for your dishwasher and see if this is a problem that has come up before ok, let me know how you get on?

    Does the sound start as soon as the dishwasher starts and is sound all the way through the cycle and when does the sound stop i will have a look whilst i wait for your message ok

  • paul proctor Nov 28, 2007

    Hi it could be a beraing on one of the spray arms are you able to take the back off at all and then try it so you can hear if the noise is coming from the top or bottom, front or back its difficult for me to figure out what it is without me actually being their but i will do my best for you.

    you say moving it did lesson the noise a bit it could be that the unit wasnt level when it was put in and the spray arm has got noisy because of it being un level.

    do the spray arms make any noise when you spin them yourself.

    If it is possible to operate with you taking the back off could you let me know where the noise is coming from also does it operare properly ie cleaning everything as it always has or is it operating poorly. I will post a message in expert forum and get advice from other experts for you i will let you know what i find out.

    let me know how you get on ok speak soon

    sorry you did tell me where the noise is coming from in that case it probably is coming from the timer part of the circuit board as the dishwasher somtimes get stuck in a certain cycle the problem is deffinately going to be your timer these are difficult to replace yourself and will require some soldering but doing it yourself without a circuit tester would be difficult as you could replace the part that has problem and then it could go noisy again.

    You will need to trace all the circuit back from the timer to eliminate it being a resistor that has gone witch would have caused this part to go.

    If the noise is coming from the front and not the back then it is going to be a circuit problem and not a mechanical one witch i sugested first if you are confident in stripping the dishwasher down and have relevent testing equipment then you will need to get technition spec sheet to get the part no.

    the other option is call somebody out and explain to them the problem they will order the part and replace for you and should offer some sort of warranty on the part at least this way they will check anything before the timer to make sure its not going to happen again.

    This will be the cheapest option if you have to buy equipment and soldering equipment yourself youll probably pay more than the price of a new one the part itself should be about 40 to 50 pound uk and to fit it about 40 pound so your looking at about 80 to 100 pound for someone to fit it and get a warranty.

    If the noise is coming from the front top it is deffinately circuit problem. if you have the equipment and think you can do it yourself i should be able to find you a tech sheet or find a site to send you two.

    Sorry but their is no easy fix to this but on the other hand it might just be a bad solder problem this will cost alot less for someone to repair this does happen quiet often that after time the solder gives up on maybe a resistor and all it takes is to re solder it.

    The timer is not something you can replace easily but let me know what you want to do ok

  • paul proctor Nov 28, 2007

    it probably wont be the controll circuit as it is sticking in a certain cycle it is more than likely the timer on the way out

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.

Extremely noisy Whilrpool, sounds like electrical resistance.

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.
