One of the most frequently broken parts of a washing machine, but at the same time a very important one, is the drain pump.
What is a washing machine pump?
It is an asynchronous motor with a snail (housing), filter and suction device.
The pump motor is low-power, up to 130 W, with a magnetic rotor that rotates only in a certain order.
The pump is responsible for the flow of water into drum and for drain.
Service life of this part about 11 years with careful maintenance of the washing machine.
The washing process is impossible without this part functioning properly. In 90% of cases, the problem lies in the geometry of the worm housing through which water flows.
Causes of drain pump failure
Drainage is difficult. You need to inspect the drum and determine if there is water in the tank after the wash cycle. The solution is cleaning the pump.- Problem with the impeller. Manufacturers recommend replacing this part every 6 years, as it wears out and shifts during this time.
- The blades or housing are damagedIn most cases, a complete replacement of the part will be required.
- The pump is noisy.When the machine makes a noise while draining loud soundsThis indicates deformation of its components. There may be cracks, chips, or water ingress in the parts.
If the pump is faulty:
- the water drains from the machine with difficulty or does not drain at all;
- the equipment hums when filling or draining water;
- the amount of water decreases during collection;
- there are constant failures and cancellations of the specified program.
To begin repairing or replacing a part, you need to know where the pump is located in the washing machine and how to get to it.
Where is the pump located in a washing machine?
All control units in many models washing machines located at the bottom.
U Veko and Ardo in the same place where the pump is located in the washing machine Samsung - below with access through the bottom.
For example, to get to the pump in a washing machine Zanussi and Electrolux, it is enough to simply remove the back cover.
Cars Bosch, AEG, Siemens You'll have to disassemble the front. Accessing the pump in these models is a bit more difficult because you'll first have to remove the loading hatch and then the front panel. The first rule to follow when starting work is to disconnect the power to the appliance.
Before touching the washing machine pump, you need to look into filter.
If it's in good condition and there's no blockage, then you can inspect the terminals. Sometimes they come loose. Only then should the volute be separated from the pump and its blades inspected. Then you can begin repairing and replacing the faulty part.
The final stage will be assembly and installation of the pump in place, followed by a test check of the machine's functionality.
