In cold water, things do not wash properly, so if you notice that the washing machine does not heat the heater, you need to urgently replace it. How to find a breakdown and return the correct temperature regime, we consider in the article. Washing in cold water can take place for several reasons - we list the signs that give out the defect of the heater.
Why TEN does not heat, but works
The reason that the heating of water does not work, can be not only the heater itself. There are quite simple problems:
- Invalid connection. Happens when the hoses are not positioned correctly - as a result, water is collected and then merged. Then the heater simply does not have time to heat it.
How to properly connect a washing machine, read in previous articles. - Check the selected mode. You may have installed a wash program in cold water. For example, "Delicate washing" and "Wool" pass at 30-40 degrees, therefore strongly does not warm.
You need to make sure that the stylalka does not really heat the water. Attach the palm to the hatch after 15 minutes from the beginning of the cycle - after washing do this late, since rinsing and so goes in cold water. If the glass is cold, there really is no heating.
This is the only external feature, which determines the lack of heating.
Why does not the heater work in the washing machine
Why did the heating element break down in the washing machine? The reasons can be several:
- The heater wiring is broken. It does not receive a signal from the module to start operation and heating.
- Burnt TEN itself, and it needs to be replaced urgently.
- The TEN thermostat broke, which measures the temperature of the water.
The main cause of combustion of the heating element is scale. It arises because of the impact of poor quality powder and raw water. The filter on the filling valve delays only large debris from the water pipe. And the heavy salts that form part of the water settle on the TEN.
Scale is dangerous because it accumulates, stains and does not allow TEN to give up heat normally - it does not heat through a thick crust. As a result, more electricity is used for heating - the heater burns out.
To prevent scale, it is recommended to carry out prophylaxis with special agents or citric acid.
Often the cause of the malfunction is a power surge. A sharp drop causes the combustion of the wiring or the heating element itself.
Dangerous situation when the heater starts punching on the body. You can understand this by the fact that it knocks out the RCD, in the running cases, the touch to the body of the machine can respond with a shock of current.
How to find a breakdown
If you do not know what to do, below we will look at the basic methods of self-diagnosis.
Get out and check the heater
To determine whether the heater is burnt and does not heat water, you need to get it out of the case. Depending on the model, the heater may be located in different parts of the AGR.
In washing machines "Bosch LG, "Siemens" TEN is located in front. To get it, act like this:
- Unplug the machine from the power and communications, remove the top cover from it.
- Go to the front panel and remove the dispensing tray by pressing the catch in the center.
- Unscrew the screws that hold the control panel.
- Squeeze its latches and unfasten the wiring.
- Remove the plinth panel.
- After opening the door of the hatch, remove the clamp from the sealing rubber. Put the rubber inside the tank.
- Remove the two bolts of the UBL lock.
- After unscrewing the screws around the perimeter, remove the front panel from the housing.
- Under the tank is a heating element.
In the stilalk stamps "Ariston "Indesite" the element is at the back, so you just need to remove the back panel.
Determine the closure or break
Examine the heater: if there is a lot of scale on it, then the cause of the malfunction is clear. To ensure that the part is blown, remove it from the case and take the multimeter.
- Take a picture and disconnect the wiring of the element.
- Loosen the central nut of the heater and put the bolt inside.
- Bring the edges of the flat screwdriver, remove the heater from the socket.
Set the multimeter to the resistance measurement mode. When applying the probes to the contacts of the element, watch the indicators.
TAN working if the screen shows up to 24 ohms. When it shows the number 1 or infinity, it means that a break occurred. The number 0 indicates the resulting fault.
Check for breakdown on the housing
To check the heater for a breakdown, switch the multimeter to buzzer mode. In this case, the device will beep.
- Attach one probe to the heater outlet.
- Attach another probe to the body.
- The multimeter issued a signal - there is a breakdown to the case, the heater needs to be replaced.
Buy a heater only for your brand and model of the machine.
The thermistor, which is located in the TEN housing, may also not work because of the scale. If the thermistor is working, simply move it to a new element and reinstall it.
Inspect and replace wiring
To the heater does not come voltage, if the wiring is not working. Examine all wires and contacts. If you notice burnt places, the wiring needs to be replaced.
Now you know that you can check and replace the heating element yourself. If it does not heat, start by eliminating random errors in connecting the machine or selecting programs.
