Question about Jenn-Air Dishwashers

Open Question

The unit (Jenn Air E39927 Type 776-0) is making a loud vibrating noise during 2-3 cycles. It sounds like there could be some debris causing this and I'm wondering if there some simple inspections I could do myself. The machine is cleaning and operating fine otherwise.

SOURCE: Diswasher motor making noise during wash cycle

It could be the impeller on the motor. The impeller fits over the shaft of the motor and might have split/broken up. That funny noise is probably the shaft spinning inside the damage impeller. Fortunately the impeler is fairly inexpensive and easy to replace. I believe there are one or two parts/covers to remove that are held in by a roughly half dozen torx screws.

SOURCE: 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.

When brewing it makes a loud noise


I have 2 Cuisinart Coffee makers. Both make loud humming noises during the pump cycle. In my units, the water reservoir vibrates when the pump is active. Test by hand pressure on the water reservoir when brewing.
I experimented with adhesive foam pads and they worked well but...they eventually fell off. I often just push the unit against the wall behind it.

Sudden loud vibration from the door of my Whirlpool dishwasher. Replacing the part didn't help.


see this causes and fix it. God bless you
Drain Pump If the dishwasher is loud during operation, the drain pump might be defective or might have some debris in it. This is a common problem.
Circulation Pump If the dishwasher is loud during operation, and the noise is a continuous drone similar in speed to the circulation pump sound, it's likely that the circulation pump motor bearings have failed. Once this happens the circulation pump will have to be replaced, the bearings are not repairable.

Drain Impeller If the dishwasher is loud during operation, the drain impeller might be broken, or there might be debris in the pump. Generally, to gain access to the pump the top of the pump housing will have to be removed.

Pump and Motor Assembly If the dishwasher is loud the motor bearings, drain impeller or wash impeller might have worn out. All three of these components are part of the pump and motor assembly. It may be possible to replace one of the impellers, but the motor bearings cannot be repaired. In that case the pump and motor assembly will need to be replaced.

Wash Impeller The wash impeller is a small, plastic blade. The motor spins the impeller forcing water through the spray arms to clean the dishes. If one or more blades has broken off of the impeller the dishwasher is loud. The impeller can also scrape against the pump housing if it is damaged, warped or bent.

Circulation and Drain Pump Motor If the dishwasher is loud during operation, and the noise is a continuous drone similar in speed to the motor sound, it's likely that the circulation and drain pump motor bearings have failed. Once this happens the motor will have to be replaced, the bearings are not repairable.

Water Inlet Valve The water inlet valve is an electrically controlled water valve. When it is new, the water inlet valve is very quiet. Over time, the diaphragm inside the valve deteriorates and deforms. This deformation interacts with the water rushing in and can cause a loud vibration, buzzing, squealing or other noises. If the dishwasher is loud during the filling cycle, replacing the water inlet valve may solve the problem.

Whynter Portable Air Conditioner Model: ARC-14S. Problem: It sounded as if something fell inside the unit while it was operating (cooling) then it started to vibrate horribly. The vibration is only...


Hi,Whynter Portable Air Conditioner has many moving parts, and they all make noise and cause vibrations. Some of these parts are more likely to causing shaking and loud noises, and sometimes this signals a larger problem, something to watch and scrutinize. If serious enough, it calls for a repair.

Loose Parts

Loose parts cause the majority of shaking and vibration noises in your air conditioner. A few of the most common loose parts include the air compressor, the piston rods and even the fan or blower unit itself. These noises are clunking, clanking sounds that occur along with a vibrating action. The only method of repair is a complete compressor replacement, which is a repair only a certified air conditioner technician is qualified to make. The compressor is a fully sealed component, so individual parts in the compressor cannot be repaired.

Fan Blades

Fan blades cause noise, shaking and vibrations even when properly secured. If fan blades contact the exterior structure of the air conditioner due to a bent fan blade or broken and misaligned grate, a constant, repetitive noise and vibration results, which sounds like a ticking or banging from the interior of the air conditioner. Vibration in this case is limited but still present.

Mounting Brackets

When an air conditioner shakes, there is a problem with the mounting brackets. These brackets hold the air conditioner compressor steady as it operates. Normal vibrations and shaking would otherwise occur without these brackets. A loose mounting bracket causes the air conditioner to rock back and forth and creates a clanking sound. As the compressor starts up, this rocking and clanking sound begins, resulting in a very loud and fast vibration and noise. It also occurs when the unit shuts down.

Other Sounds and Vibrations

Sometimes air conditioners squeal, hiss, hum or screech. Each noise is often accompanied by a vibration. Humming sounds along with a vibration may indicate a bad capacitor, the electrical part responsible for starting the machine. Hissing sounds tend to indicate a pressure problem while screeching and squealing sounds are fairly common in window air conditioners and in central air conditioners. This sound is also a result of the compressor motor. It usually starts when the unit turns on and continues through its normal operating cycle. Vibrations always occur in the air conditioner due to moving parts and the compressor motor's operation.


Hope it helped..

Haier ESA 3185 AC won't cool; makes escalating loud vibrating noise near front panel/ filter


Have someone check the run capacitor of this unit. If the run capacitor is bad over shorted it can cause the unit to run and short cycle on a current overdraw. This makes for an electrical imbalance in the compressor motor. Next step is the compressor is faulty.

Loud vibrating/humming noise


Okay...based on the model number, this is a Frigidaire manufactured dishwasher. If you go to searspartsdirect.com and type in the your model number in the Search menu, you will find a useful illustration under the "Motor and Pump" heading. The drain pump is listed as item #60 in the drawing. Before you go through any major dis-assembly, check to make sure the pump is securely in place and not loose. Sometimes the pump comes loose from the mounting bracket and vibrates. Also, sure nothing is laying against it causing vibration noises (I've seen this before). If the solution is not that simple, remove the spray arm assembly inside the dishwasher and inspect all the debris traps under the spray arm assembly. The wash pump and drain pump sumps are located here. Check to make sure there's nothing obstructing the input to the drain pump. Lastly, if all else fails, remove the drain pump and inspect the impeller. If the you've inspected everything and still have the noise problem, replace the drain pump. The motor could possible be failing. The part number on the Sears website is 154580301 and costs about $40. Repairclinic.com has the same part listed as item #1257094 for $37.50 if you wish to do some comparable pricing.

I hope this helps you. If you need further assistance, please post back and let me know.

PS Even the quietest of all dishwashers will make some noise. However, if it has gotten to the point where you can hear it in the next room, you probably need to inspect to find the source of the problem. This is not true with all dishwasher manufacturers, but in many cases, the only difference between your "Quiet-Pack" line and regular low-end models is added insulation behind the door and lower panel to help quieten noise.
