Damage to the circulation pump

Excessive noise from the dishwasher is very often caused by a malfunction of the circulation pump. The reason for this is a small thrust bearing in the form of a ring. This element wears out rather quickly. Daily use of the device will require replacement of the graphite bearing after about 2 years.

To eliminate the noise resulting from improper functioning of the circulation pump, you must:

disconnect the device from the power supply

unscrew the pallet, if it is provided by the equipment set

after once access to the pump is open, we disconnect the wires and pipes, after loosening the clamps a little

remove the pump and detach it from the pair of wires that are attached to it from the back.

Then follows the careful disassembly of the pump, disconnecting the heating elements from an electric motor. Do not forget that such work requires special care and accuracy, so if you are not sure that you can do it, do not do it yourself.

Malfunction of the drain pump

The source of the hum is the drain in the event that the machine starts to publish uncharacteristic for her, the sounds during the discharge of waste water. You can remove this item from the dishwasher after removing the pallet, disconnecting the hoses and electrical wires, and unscrewing the screws holding this pump. Pay special attention to the impeller when disassembling the pump. If it is slightly damaged or deformed, then it must be replaced.
