The washing machine is not silent during operation, but makes sounds - during washing, rinsing, or during the spin program.
But sometimes the car starts to rattle, hum, whistle and make very loud noise, which does not have a positive effect on the human nervous system.
How can you tell which noise is normal and which is not?
It all depends on the drive.
Why does my washing machine hum or whistle when washing?
For a belt-driven washing machine, the normal noise level is between 60 and 72 dB, and for a direct drive, it's between 52 and 70 dB. Otherwise, the noise may indicate a malfunction.
This problem can occur when you first start the machine. In this case, you should check the shipping bolts; perhaps they were simply forgotten and not removed. Alternatively, the machine may have been installed incorrectly and need adjustment.
In other cases, there can be many reasons for the breakdown. Let's look at the main reasons why a car might make strange sounds.uki.
Wear of bearings, belt, counterweight and pulley
Pulley
A common problem with older automatic washing machines. If your washing machine starts humming or making clicking sounds, it's likely that the pulley has become loose.
Belt
To access the belt and pulley to check their functionality, you need to:
Remove the back cover, under which there is a large wheel - this is the pulley.- Inspect the pulley for defects. If there are none, we move on.
- The drive belt is placed on a pulley and requires careful examination for defects, because even a minor chip affects its operation.
Counterweight
If the belt is in good working order, then you need to get to the counterweight.
To do this, you first need to find the counterweight. It looks like a large stone bolted to the car. If the mounting holes are larger than the bolts, the counterweight needs to be replaced. To be 100% sure, try rocking the counterweight from side to side. If it wobbles, it definitely needs to be replaced.
Bearing
An unfortunate failure is a bearing failure. Why? Because replacing it yourself is very difficult, but not impossible.
- You will need to remove the heating element and pull out the engine, moving the belt aside.
- Next, take out the tank, which needs to be cut in half.
- All that remains is to knock out the bearings and replace them with new ones.
Typically, the seals that seal the tank are the first to wear out. This allows moisture to enter the bearing, causing it to rust and break.
Problem with the hatch cuff
The washing machine whistles or makes a loud humming noise during the spin cycle, and it’s unclear what the cuff has to do with it?
But in reality, if the cuff is installed poorly, it may not fit into the groove of the machine, which prevents the hatch from closing tightly.
Or the cuff may be hanging down or even installed haphazardly. If the cuff is catching on the edge, the following steps will help fix it:
- Inspect the cuff.
- Find the clinging edge.
- To correct a small edge up to 0.5 cm, you will need fine sandpaper (not a knife), which is inserted into the gap between this edge.
- The next step is to turn on the spin cycle. The idea is that the drum will spin, rubbing off the protruding part, and the machine will stop making noise. If the edge is larger, the best solution is to replace the seal.
Foreign objects
The moving parts of the machine are not always the culprit of the malfunction.
The washing machine sometimes whistles when the drum is spinning due to the presence of foreign objects.
These could be paper clips, pins, coins, nails, underwire, etc. These cute and small items are quite capable of sending the car to the landfill.
If there is a foreign object between the drum and the cuff, it can be removed.
If it is out of reach, you will have to disassemble the car.
- The back cover is removed,
- then the heating element is removed,
- after which the causes of the grinding noise are removed.
If the heating element option is not an option, you can access the inside of the machine through the outlet. To do this, lay the machine on its side and remove the bottom cover. The outlet is also removed, allowing you to access the items.
The brushes in the engine are worn out
Typically, this problem is accompanied by a loud humming and knocking noise from the washing machine. Replacing the part with a new one requires completely disassembling the washing machine.
It is wiser to entrust the task of replacing the brushes in the engine to a professional.
Problem with drain pump
A washing machine humming when draining is a typical sign of a malfunctioning drainage system. This problem is usually solvable and rarely requires replacement. To diagnose the problem, the pump is removed from the machine and cleaned.
If the filter is clogged
If the machine drains but makes a strange noise, the filter may be clogged. Cleaning it may help. The filter is located at the front bottom of the machine and should be unscrewed counterclockwise. When removing the filter, water may spill onto the floor; have a low container ready to catch it.
It's important to understand that any sound that's unusual for your assistant's operation is a reason to look for the cause of the malfunction and fix it!
If you can't do it yourself, don't torture yourself and your car; maybe it's better to trust a specialist?
