- Dishwasher Making Noise Repair in London
If your dishwasher is making clicking, buzzing, grinding, rattling, knocking or unusual noises during washing or draining, it is best to have the fault checked before it causes further damage.
At London Appliance Repair, dishwasher noise faults are checked by looking at when the noise happens, what type of sound it is and which part of the appliance may be involved, including the drain pump, circulation pump, spray arm, motor, filter, trapped objects and installation.
Clicking: spray arm or dishes may be touching
Rumbling: pump issue or trapped object
Buzzing: pump jam or motor strain
Grinding: moving parts may be rubbing
Knocking: poor loading or appliance vibration
- UNUSUAL DISHWASHER NOISE
Not every dishwasher noise is normal
A dishwasher will always make some sound during normal use. Water spraying, spray arms moving and water draining can all be part of a normal cycle. However, if the noise has suddenly become louder or sounds like rattling, knocking, grinding, buzzing or scraping, it should not be ignored.
An unusual dishwasher noise can start from something simple, such as a piece of food or glass caught in the filter, but it can also be linked to the drain pump, circulation pump, motor, spray arm, internal wear, hose movement, poor levelling or incorrect installation.
For a Dishwasher Making Noise fault, it is important to know when the noise happens: at the start of the cycle, during washing, while draining or near the end of the programme. This timing helps narrow down the likely cause.
Clicking or knocking noise
The spray arm may be hitting dishes, or items may not be positioned correctly inside the baskets.
Rumbling noise
This can be linked to the drain pump, circulation pump, blocked filter or small objects caught inside the appliance.
Buzzing noise
If the pump is jammed or the motor is under strain when trying to start, a buzzing sound may be heard.
Grinding noise
A grinding sound should be taken seriously, as it may mean a part is rubbing against a moving component.
NOISE CAN COME FROM INSIDE THE APPLIANCE
Sometimes a dishwasher noise starts from one small part
Small pieces of glass, bone, food seeds, labels or metal fragments can enter the filter or pump area and create noise while the dishwasher is running. If this continues, it can put extra strain on the pump or internal parts.
Some noises are not caused by trapped objects and may come from gradual wear in the pump, motor, spray arm or internal connections. That is why hearing the noise alone is not enough; the location and timing of the sound also need to be checked.
Proper diagnosis helps identify the real cause before the problem becomes more serious.
At the start of the cycle
The noise may be linked to filling, door locking, the initial pump action or a part being stuck.
During washing
Clicking or knocking during washing is often linked to the spray arm, dish loading or circulation pump.
While draining
Rumbling, buzzing or scraping sounds during draining can point to the drain pump, drain hose or outlet route.
At the end of the programme
Noise near the end may be linked to drying, the fan, final draining or appliance vibration.

Common causes of unusual dishwasher noise
When should you stop using the dishwasher?
If the noise is very loud, you notice a burning smell, the appliance is vibrating heavily, water is not draining or you hear strong grinding or rumbling, it is better to switch the dishwasher off and avoid using it until it has been checked.
Continued use in some cases may cause more damage to the pump, motor, spray arm or drainage system.
