Dishwashers produce noise while they operate due to the internal pumps and moving components, however, if you feel the noises your dishwasher is making are unusual, this guide will provide some tips to help rectify the issue.
If you have just received your dishwasher it is likely that loud noises will disappear over time. Your dishwasher may have had a long journey which has caused the seal to dry out, after a couple of cycles will remoisten the seal and the noise will cease.
If the noise is not occurring often it is likely due to the dishes in that cycle and is nothing to worry about.
Some audible sounds are normal
- Sound from detergent cup opening
- Spinning of arms
- Splashing of water
- Sounds of different functions beginning and finishing
Knocking noises can be caused by loose items inside the dishwasher. There are many moving parts inside a dishwasher so it is important to ensure everything is secured.
A constant knocking noise will likely be caused by the spinning arm, when the dishwasher is not in operation inspect the spinning arm to see if there are any dishes hanging down causing an obstruction or dishes sticking up causing an obstruction and restack the dishes accordingly. You should be able to lightly spin the spray arm and it should be able to do a full revolution without binding.
Another cause of knocking is the drainage hose being loose and making contact with another surface. Check behind the dishwasher to ensure the hose is secured in place.
Motor Hums And Water Inlet / Outlet Noises
If the dishwasher has not been used regularly or for the first couple of uses there may be a humming noise from the motor. If you do not use it often, remember to set it to fill and pump out every week, which will help keep the seal moist. The sound will dissipate over a couple of uses.
A droning noise can indicate an obstruction in the draining pump, check the filters at the bottom of the dishwasher are free from debris. If the dishwasher is older than 1 year check the inlet valve for wear and tear.
If the drain pump does not turn off this could be due to an overflow. The system is designed to detect an overflow. When it does, it shuts off the circulation pump and turns on the drain pump. If the drain pump does not turn off there is too much water inside the unit. Please contact our Customer Care Team.
If the dishwasher isn't level this may generate a vibrating noise from the motor. Ensure the dishwasher is level by adjusting all of the feet as per the user manual.
If you are concerned about the noise you are hearing and this has not assisted in rectifying the issue please capture the sound in a video recording and contact our Customer Care Team.
