Dishwasher starts making a lots of noise

Issue description:

Is there a noise after turning on the device, or, on the contrary, is there complete silence? There may be reasons for this:

When switched on, the machine hums and does not draw water. Check for water in the tap. Turn the shut-off valve: it may have been accidentally blocked.

Press the hopper door closer. When the door is open, the cycle will not start and water will not flow into the chamber. This is done to protect against leakage. The equipment may make a hum, but not work, or beep during operation.

The inlet hose is pinched or clogged. Check that the hose is correctly connected: it must be level, without kinks. Detach it from the body and inspect for clogging.

If the equipment starts humming during operation, check the installation of the machine, as well as the location of the dishes in the baskets.

The causes of the most difficult breakdowns, when the machine hums, cracks, but does not work, are:

breakdown of the drain pump

wear of the pump bearing

breakdown of the circulation pump

malfunction of the intake valve.

Dishwasher starts making a lots of noise

Solution:

Checking and restoring the work of the dishwasher.

You need to start the inspection with the parts that could get clogged during the washing process. This leads to the fact that the dishwashers make noise and creak during start-up.

Sprayer and impeller

If you have built-in appliances, it is better to pull it out of the cabinet and disconnect all communications before starting work. Open the hopper door. Remove the baskets. Remove the nebulizers and rinse under running water. Clean the nozzles with a toothpick. Unscrew the drain filter and the mesh behind it. Clean out debris under the tap. By doing this after every wash, you can avoid blockages. If a crackling sound is heard during operation, this is a pump. It should normally work quietly. However, if solid objects or fragments of dishes fall into the impeller, operation may be blocked. How to check the pump impeller: scoop out water from the filter seat; pull the flap to the side and then towards you; check the impeller: wearing gloves, clean it of debris.

Intake valve

The machine makes a noise when taking in water, but the flow does not enter the hopper. What does it mean? Most likely, the filling valve is broken. When turned on, you can even hear clicks, as if the part is trying to fire. The element is located at the bottom of the case. Replacing the valve is easy: just unscrew the screw, disconnect the wiring. To check the mechanical part, the operating voltage is applied to the part to check whether the valve opens or not.

Drain pump

Having checked the circulation unit, you realize that something is humming in the machine again. If the noise starts when the water is drained, then the pump must be removed. You already know how to disassemble the dishwasher. Disconnect the drain pump from the unit and measure the resistance with a multimeter. If the resistance is ok, then disassemble the part and check each element. The pump is not expensive, so there is no difficulty in replacing it.
