How to check the heater washing machine: multimeter , tester , without the device

When washing the car suddenly ceases to heat water, it becomes a real problem, since a significant impact on the quality of the wash.In cold water it is impossible to wash off stubborn stains, moreover, it is poorly soluble detergent and laundry after a wash sometimes gets an unpleasant, musty smell.

reasons for which the heating does not occur, there may be several.Most often the case in a crash program module or PETN - tubular heating element.As practice shows, the most common reason - it is the latter.TEN often becomes unusable due to plaque, which occurs under the influence of hard water or low-quality household products.

learn how to self-diagnose and PETN on prevention, we describe in detail in today's article.

In order to check the serviceability of PETN, you must first gain access to it - and it will require to disassemble washing machine.The majority of current models is PETN or in the front or the rear.

• compare the front and rear wall of the unit - which one is more under that usually hides heater;
• stiralku flipped on its side and find the heater by removing the lower part of her;
• unscrew the top cover, and turning down the machine to the side, to detect PETN.

Finding heater, you can immediately dismantle it, but experts advise not to rush into this until you make sure it is a fault.Therefore, to begin with, simply disconnect the wires going to the TENu.

most affordable way to diagnose problems PETN - is a measurement of its resistance.To define it, we need to find the value of all the elements of the formula:

R = U² / P, where the R - the resistance, the U - voltage, and P - power.

voltage which is supplied to the heater is equal to the mains voltage: it is, as a rule, is 220 volts.Power PETN you can find in the corresponding section on the operation of the washing machine manual.If there is this information could not be found - on the Internet there is information about all existing models.Most often it is 2000 watts.

Now substitute the values ​​found, expect, and obtain the required amount.According to our values ​​of R = 220² / 2000 = 24.2 ohms.

The resulting calculation of resistance - a measure in which the heater can function normally.In case of failure of the heating element resistance can be changed, whereby the interruptions take place with hot water.Check the resistance can be checked with a multimeter - a device that allows you to measure various indicators of electric current.

Then adjust the multimeter and start the resistance measurement mode, and set the value to 200 ohms.Attach the test leads to the terminals of the heating element.On the device screen should appear the result of measurement.

If the resulting number is equal to or came close to what we have found the formula, then with Tan's all right.The number "1" means that there was a break in PETN.The figure "0" is displayed in the event of a short circuit.And in fact, in both cases the heating element to be replaced.

Do not forget to check out another body PETN itself on integrity.How to do this, see the following video.

If the hand is not the meter, you can test the heating element of the washing machine in other ways.The first one does not require disassembly of the unit.To make sure that the heater is functioning properly, run the wash cycle to the maximum heat mode.Then watch the rotation of the wheel to the meter - if it has started to gain momentum, then the heater will most likely OK.

second method of diagnosis of PETN - a visual inspection.If the enclosure is used identifies cracks or black spots - heater needs to be replaced.

• During the installation of the new heating element, or return to the place of the old, thoroughly check the connection - they should be completely sealed, otherwise the century of life of the heater (and, perhaps, and all of the washing machine) would bevery short lived.
• extend the term of service may be PETN, arranging his periodic preventive maintenance.Most available means - is citric acid.Just run the washing with an empty tank and covered instead of the powder a couple of tablespoons of citric acid.But do so no more than once a year, or you may damage the metal parts of the washing machine.
