Currently, the dishwasher is gaining more and more popularity among citizens. If earlier about 5% of respondents declared the availability of this item of household appliances, now the demand for dishwashers is growing steadily.
The dishwasher according to its structure has a number of similarities with the washing machine. At the same time, it is equipped much easier and includes a much smaller number of parts. The material below will address the problem of repairing parts, in particular, what to do if the heater for a dishwasher breaks down. Regardless of the manufacturer, the dishwasher can work flawlessly for several years, or maybe start to junk after a year. Anyway, dishwasher repair should not be put off in a long box and at the first sign of a malfunction, take appropriate measures.
Remember: in a dishwasher, all the details of the mechanism are interconnected, and in case of failure of one of them, the operation of the entire system is disrupted. In the future, this can lead to damage to the dishwasher itself. In this case, you will have to purchase a new one. Agree, not very nice. Therefore, we strongly advise you not to ignore the danger signals and take preventive and protective measures by periodically inspecting spare parts.
What is TEN and what are its functions
TEN is an important part of the unit for heating water. A tubular heater is responsible for selecting the optimum temperature for each cycle. For example, high temperature of water is suitable for ceramics and iron; for crystal and other fragile elements boiling water is dangerous.
When playing the dishwasher, the heating unit receives a signal about the selected program. Some dishwashers include more than ten different programs for washing all types of dishes. However, most often, owners of dishwashers use no more than four of them.
The cycle can be set manually, but most modern dishwashers are automatic and they themselves select the desired temperature and water flow limit.
Signs of damage to the heating element
Modern equipment is often equipped with signaling elements showing that there are problems. The same can be said about modern dishwashers. Most of them have an electronic diagnostic system, showing what is wrong with the equipment.
If a malfunction occurs, the display will show a combination of letters and numbers - an error code. In the instructions or on the manufacturer’s website, you can view the value of the ciphers.
However, in the event that the dishwasher has problems with heating the water, the system does not produce any errors. The best solution in this case is to conduct a routine inspection to avoid problems in the future. Prevention will help to know the condition of the equipment and take measures to prevent damage. The main signs of a violation of the water heating system can be found by the readings of the thermometer. If the thermometer does not change the initial indicator, or it does not reach the set temperature, then the heater is broken and needs repair.
Proceed as follows:
- Carefully turn the dishwasher upside down.
- The second action depends on the type of dishwasher. If you have a freestanding floor standing machine, remove the back wall, if the built-in floor side.
- Disconnect the drain pipe from the heating block and pull the entire panel towards you.
Remember! The dishwasher heater is located at the very top of the heating unit, so do not completely remove the panel. Do not unscrew the fasteners, because your task is to check the temperature sensor. By its state, you can determine the degree of malfunction.
Now you need a multimeter. Carefully inspect the wiring as well as the contacts. If you find traces of burning or soot, it is best to replace the unit. For models of the brand Bosch, Electrolux, Indesit, it is impossible to replace the heater in the dishwasher separately from the entire fuser.
What is needed to replace
The fuser is one of the most difficult to repair and vulnerable to mechanical damage parts. It is extremely difficult to repair a ten for a dishwasher yourself. To do this, you need to resort to the help of specialists, professional repairmen. It is often easier to replace a heating element with a new one. To do this, you only need a certain set of tools:
- Flat and Phillips screwdrivers
- Multimeter for measurement and troubleshooting
- Pliers
- Awl
Done! You can start disassembling. Experts advise starting repair work only if you are completely sure that the heater is malfunctioning. In this case, depending on the model, it is necessary to replace the heating element or the entire fuser. For example, for dishwashers from manufacturers of Bosch, Electrolux or Indesit, the entire fuser will have to be changed.
The fuser consists of sockets and connectors for the sensor. The case of the spare part is made of plastic. If fasteners are available, you can unscrew these parts and remove the defective heater. If there are none, then you have to replace the entire fuser. The price of the heating unit depends on the model and series of the dishwasher. Usually it varies in the region of 1000-4000 rubles.
Important! Perform a routine inspection approximately once a year. This will help to identify problems at an early stage and fix them before the entire system is destroyed.
We also advise you not to limit yourself to inspecting and repairing the fuser. When examining the "inside" of the dishwasher, you can find particles of mineral salts deposited on pipes and spare parts, or dirt that clogs the filters. In the future, this will save you considerable time and money in the event of a malfunction, such as problems with the discharge of used water.
Step-by-step instructions for replacing a heating unit
All dishwashers have a significant drawback - new models are more vulnerable and prone to breakage than old ones. However, if a ten heater is found to be damaged, repair work should be started immediately. You can buy original parts at any suitable store in your city, or order online. As soon as you have the necessary accessories, proceed.

- Done! Pump removed. Now disconnect the sensor. If your dishwasher belongs to the three previously mentioned models, where the heater and the sensor are replaced with the fuser, then remove the entire fuser in which the flowing ten is mounted for your dishwasher.
- Bottom of the spare part is fixed with a rubber bolt. You will have to search for it blindly, however, disconnecting it is very easy.
