When the washing machine Ardo the water stops heating, the wash cycle is delayed, and the laundry remains cold and poorly washed. Most often, the culprit for this problem is a faulty heating element, also known as heating element. This is a consumable item that over time becomes covered with scale, oxidizes, or simply burns out due to power surges in the network.
Replacing this part yourself is quite possible if you have basic skills in working with tools and an understanding of how household appliances work. However, it is worth remembering that Ardo washing machines have their own design features that distinguish them from more modern analogues. In particular, access to the heater may be difficult due to the design of the tank or the location of the counterweights.
Before starting disassembly, you need to make sure that the problem lies in the heating element, and not in the control module or temperature sensor. Incorrect diagnosis will lead to the purchase of unnecessary parts and unnecessary work. In this article we will analyze in detail the process of diagnostics, selection of compatible parts and the technology for their installation.
Diagnosis of heating element malfunction
The first sign of a breakdown is the lack of water heating, which is often accompanied by an error code on the display or blinking indicators. However, the machine may continue to spin the drum, creating the illusion of normal operation. In order not to disassemble the unit in vain, carry out an initial check by measuring the washing time: if the “Cotton 60°C” program lasts as long as the no-heat mode, it means the heating element is not working.
For an accurate diagnosis you will need multimeter. After disconnecting the machine from the power supply and removing the back cover (or front, depending on the model), you need to get to the heater contacts. Visually inspect the part: swelling, cracks or black deposits indicate a breakdown. If there are no visual defects, proceed to resistance measurements.
Set the multimeter to resistance measurement mode (Ohms) and attach the probes to the terminals of the heating element. Normal serviceable resistance for machines Ardo usually ranges from 25 to 35 ohms. If the device shows one (open) or zero (short circuit), the part requires replacement. It is also important to check the breakdown on the case by switching the multimeter to the continuity mode.
Touch any terminal with one probe and the metal body of the heater with the other. The absence of an audible signal confirms the integrity of the insulation. The appearance of a squeak means that electricity is leaking to the body, which is life-threatening and requires immediate attention.
Often, along with the heating element, the thermostat built into its design or installed nearby also fails. Therefore, experts advise changing these elements comprehensively, even if the temperature sensor shows normal values. An old thermostat may have play or oxidized contacts, which will lead to repeated failure in a short time.
Necessary tools and spare parts selection
The success of the operation depends not only on your skills, but also on the quality of your preparation. To replace the heating element on a car Ardo you will need a standard set of locksmith tools. It is important that all tools are in good working order and the working surfaces are clean so as not to damage the plastic elements of the case.
Prepare the following arsenal: a set of screwdrivers (Phillips and flathead), pliers, a ratchet wrench with heads (usually 8, 10 mm), a knife for stripping contacts and, of course, a new heating element. A flashlight is also a good idea, since deep inside the car the lighting is often insufficient.
When choosing a new heating element, pay attention not only to the power, but also to the geometric dimensions. Heaters for Ardo can have different length of the curved part and diameter of the mounting flange plate. Using a part that is too long may damage the tub or drum when rotating.
- 🔍 Power: Typically, Ardo uses 1700-1900 W; installing a more powerful heating element can overload the wiring.
- 📏 Length: Measure the old part from the edge of the rubber gasket to the end of the tube, the tolerance is no more than 5-10 mm.
- 🔩 Mount: Check the location of the hole for the thermostat and the shape of the clamping bar.
Original spare parts are difficult to find, since the brand Ardo no longer actively produces equipment. However, the market offers many high-quality analogues from manufacturers like Thermowatt or Irca. The main thing is that the parameters match the original. Cheap Chinese analogues often do not last long and quickly become overgrown with scale.
Buy heating elements coated with stainless steel or Teflon coating - they are less susceptible to scale formation and last longer than conventional chrome-plated models.
Preparation for disassembly and safety precautions
Working with electrical appliances requires strict adherence to safety rules. Before starting any work, be sure to turn off the washing machine. Ardo from the electrical network by unplugging the plug from the socket. Don't rely solely on the power button on the control panel.
⚠️ Attention: Even after disconnecting from the mains, a residual charge may remain in the capacitors of the control module. Do not touch the electronic boards with bare hands immediately after removing the covers; let the machine stand for 10-15 minutes.
The next step is to shut off the water supply. Unscrew the inlet hose from the water supply and drain the remaining water from the machine. To do this, open the drain filter located at the bottom of the front panel by placing a flat container. Up to a liter of water may remain in the machine, which will leak out when the unit is tilted.
Free up space around the machine. You'll need to ensure access from all sides, as disassembly may require removing both the front and back panels. Cover the floor with cardboard or old cloth to avoid scratching the flooring or losing small parts that could roll out.
Take a few photos of the wire connections before disconnecting them. In older models Ardo The color markings of the wires can fade, and it is very easy to confuse the thermostat, ground and power contacts. The photographs will be your insurance for reassembly.
☑️ Ready for repair
The process of dismantling the old heating element
Most washing machine models Ardo the heating element is located at the bottom of the tank. It can be accessed through the back wall, but in some compact models you have to remove the front panel. Start by removing the top cover by removing the two screws on the back and sliding it back.
If accessed from the rear, simply unscrew the mounting bolts around the perimeter of the rear metal panel. If the heating element is hidden at the front, you will need to remove the control panel and the front part of the housing. Be careful with the plastic latches found on older cars. Ardo become fragile.
Locate the heating element leads in the center of the tank. The power, ground and thermostat wires are suitable for them. Carefully disconnect the connectors by pulling on the terminals, not the wires themselves. If the terminals are oxidized and cannot be removed, use pliers, but do not jerk so as not to break the wire inside the insulation.
The central nut holding the heating element is usually 10 mm in size. Unscrew it with the key. After this, the heating element pin can go inside the tank. Do not try to immediately pull out the heater; it is tightly pressed with a rubber cuff. Carefully pry the edges of the flange with a screwdriver, being careful not to damage the tank enamel.
Sometimes the heating element “sticks” so strongly that it is impossible to remove it without damage. In this case, you can carefully cut the old heater with a hacksaw without touching the walls of the tank. This is a barbaric method, but it is justified when the part is thrown away anyway. After removal, thoroughly clean the seat from scale and dirt.
Installing a new heating element
Before installing a new part, inspect the rubber seal. It should be elastic and smooth. If the rubber on the new part is dry, lubricate it with a small amount of water or soapy water to make it easier to fit. The use of oils or grease is prohibited, as they can destroy the rubber.
Insert the heating element into the hole in the tank. Make sure it goes in straight and all the way. When tightening the central nut, it is important not to overdo it. Excessive force may cause the rubber gasket to pull out or burst, while too little tightening will cause a leak.
⚠️ Attention: Check the position of the clamping bar. It should press the elastic evenly around the entire circumference. If one edge of the heating element goes deeper than the other, depressurization will occur when heated.
Connect the wires in reverse order. First the ground, then the power, and lastly the thermostat terminals. Make sure connections are tight. If the terminals are loose, you can carefully tighten them with pliers. Poor contact will lead to sparking and melting of the wiring.
Check that the wires do not touch the heating parts of the heating element or hot areas of the tank. If necessary, secure the wire harnesses with plastic ties or standard holders. Vibration during spinning should not displace communications.
The nuances of installing a heating element with a thermostat
If you are replacing the heating element with a model with a built-in thermostat, make sure that the capillary tube of the sensor is not kinked. On Ardo models, the thermostat is often inserted into a special socket on the flange. Before installation, apply a little thermal paste to the sensitive element of the thermostat for better heat transfer, although many craftsmen do without this.
Comparative table of heating elements characteristics
To avoid mistakes when purchasing, check the technical data. Below is a table with typical heater parameters for various machine series Ardo. Please remember that visual similarity does not guarantee identical electrical characteristics.
| Parameter | Standard heating element Ardo | Short version | Strengthened series |
|---|---|---|---|
| Power | 1700 W | 1700 W | 1900 W |
| Voltage | 230 V | 230 V | 230 V |
| Flange diameter | ~48 mm | ~48 mm | ~48 mm |
| Curved length | 260 mm | 190 mm | 260 mm |
| Tube material | Stainless steel steel | Chrome-nickel | Stainless steel steel |
Using a heating element with a lower power will increase the washing time and ineffectively dissolve the powder. Installing a more powerful element without appropriate modifications to the wiring and control module can cause a fire hazard.
Pay attention to the markings on the metal flange. The voltage, watts and often the manufacturer's code are indicated there. Matching the length of the curved part is a critical parameter for Ardo machines, since their tank is narrow, and a long heating element can rest against the drum.
Machine assembly and test run
After installing the heating element and checking all connections, you can begin assembly. Reinstall the removed panels and tighten all screws tightly. Return the machine to its original position, connect the drain hose and filler pipe.
Do not plug the machine into the network right away. Open the water tap and allow the tank to fill for 1-2 minutes. Carefully inspect the installation site of the new heating element and all hoses for leaks. If water drips, tighten the heater center nut.
Only after making sure of the tightness, plug the washing machine into the outlet. Run a wash cycle at 60°C or 90°C without laundry. After 10-15 minutes of operation, carefully touch the glass of the hatch: it should become warm. If the glass is cold and the program continues, the heating element may be faulty again or not connected.
- ✅ Check for any extraneous noise or vibrations.
- ✅ Make sure the machine draws and drains water correctly.
- ✅ Make sure that the machine knocks out (if it is weak) when you turn on the heating.
If the test run was successful, the repair can be considered complete. Regular use of descalers or magnetic filters will help extend the life of your new heating element.
A correctly selected and installed heating element lasts on average 3-5 years, after which the procedure will most likely have to be repeated due to natural wear and tear and water quality.
Frequently asked questions (FAQ)
Is it possible to run a wash without a heating element?
Technically, the machine will work, spin the drum and drain the water, but the wash will take place in cold water. This is acceptable as a temporary solution if you are washing delicate fabrics that do not require heat or using active cold wash chemicals. However, the control module may generate an error and block the process if the temperature sensor detects no heating for a certain time.
Why did the new heating element burn out after a month?
There may be several reasons: poor quality of the spare part itself, power surges in the network, a malfunction of the heating relay on the control board (which continues to heat even after reaching the desired temperature) or lack of water in the tank when turned on (dry start). Poor grounding or oxidation of contacts is also often to blame.
Is it necessary to lubricate the rubber element of the heating element with sealant?
The use of silicone sealant is not recommended by manufacturers. The rubber cuff of the heating element is designed for sealing due to its elasticity and tight fit when clamped. The sealant can make future replacement difficult and cause leaks if it dries. Enough clean water to facilitate installation.
How often do you need to change the heating element on an Ardo machine?
The service life of the heater depends on the hardness of the water and the frequency of washing. On average, when using water softeners and moderate load, the heating element lasts 3-5 years. If the water is very hard and you do not use descalers, replacement may be required after 1.5-2 years.
