What does error E07 mean in a Candy washing machine, how can I fix it?

Candy washing machines are distinguished by affordable prices and good assembly reliability.

To identify any malfunctions, these units are equipped with a self-diagnosis system that signals breakdowns.

For example, if there are problems with the movement of the drum, the Candy washing machine displays error code E07.

To clarify the cause of the malfunction, you need to pay attention to the accompanying symptoms and carry out a simple check.

Decoding the code that the Kandy washing machine produces, how is it indicated?

The error, which is indicated by code E07, occurs after attempts to start the electric motor or start a washing cycle.

Depending on the model of the washing machine, with this error The following code may appear on the display:

• "E07"
• "Err 07"
• "Err7"
• "Error 7"
• "E7".

On SMA without a screen

Candy washing machines without a display indicate a malfunction by flashing LED indicators. When error E07 occurs, a series of 7 flashes occurs, then a pause for 5-13 seconds and the code is repeated.

Depending on the SMA model, the following LEDs light up:

• “Intensive wash” and “90”;
• “Intensive wash” and the top indicator (“Start” or “90”);
• "Wash in cold water."

Causes and Troubleshooting

The cause of the E07 error can be determined by the accompanying signs: the moment of its appearance, the presence of extraneous noise during operation, the nature of the drum rotation, etc. For a more accurate diagnosis, you will need to disassemble the SMA and check the main elements with a multimeter.

Broken hatch locking device

If the appearance of error E07 is associated with a malfunction of the UBL, then the problem is most often detected after washing. A locked door makes it impossible to remove laundry, even if there is no water in the tank and the cycle is completely completed.

The cause of the breakdown may be:

1. Impaired function of the device itself (electronic or thermal).
2. Damage to the wiring between the control unit and the UBL.
3. Failure of the part of the board that is responsible for controlling the hatch.

Problems with the locking device can be detected at the very beginning of the wash. Without receiving a signal to close the hatch, the electronic module cannot start the program and the movement of the drum.

How to check and replace the device:

1. Disconnect the unit from the power supply. If necessary, drain the remaining water through the filter at the bottom of the washing machine.
2. Prepare a thin and strong rope. Use a flat-head screwdriver, file or knife to press it into the gap between the hatch and the body opposite the lock.
3. Gently pull the ends of the rope until the tongue clicks.
4. If it was not possible to open the SMA using a rope, it is necessary to remove the top panel and tilt the unit back so that a large opening is formed between the drum and the hatch. After this, the UBL holder can be felt and snapped off manually.
5. After removing the laundry, bend the hatch cuff, loosen the clamp and seal.
6. Inspect the lock, remove the fasteners and bend the latches holding the UBL.
7. To check the functionality of the device, it is necessary to measure the resistance on the neutral and phase contacts, as well as on the neutral and common. In the first case, a three-digit number, which depends on the lock model, is considered the norm, and in the second case, values ​​greater than 1 are considered.
8. You can also apply mains voltage to contacts L and N, and then press the moving part with a screwdriver until it clicks. If the UBL is working properly, the lock is locked with a latch.
9. If there is a problem with the hatch locking device, you must replace it with a similar one and install a new part in the socket.

You can carry out diagnostics yourself only for thermal UBLs; in case of breakdowns of electromagnetic devices, it is recommended to contact an AMS repair specialist.

Tachometer malfunctions

The tachometer transmits information about the speed of rotation to the control unit. This allows you to control the intensity of the engine and change the mode depending on the program.

Malfunction of the tachometer or wiring between it and the board may appear as follows:

• when you turn on any program, the drum does not rotate;
• after starting or in the middle of the cycle, the SMA suddenly switches to high speed;
• The spin speed is too low.

There are two ways to carry out diagnostics with a multimeter:

1. Connect the probes to the main contacts and determine the resistance (nominal level - 60-70 Ohms).
2. Switch the device to voltage test mode and crank the engine, observing whether the multimeter readings change.

If the part is in working condition, you need to look for an open circuit or a fault in the control board.

Failure of the electronic unit

Error E07 due to malfunctions of the control unit may be accompanied by the following symptoms:

• the drum does not spin from the very beginning of the cycle or program;
• The SMA hatch does not open;
• The engine of the unit does not work;
• The drum only rotates in one direction.

To check the module, you need to unplug the machine for 10-15 minutes, and then restart any washing program. If the part malfunctions briefly, rebooting may solve the problem, but if the problem occurs regularly, you need to check the condition of the board.

If restarting the SMA does not help, you must again disconnect it from the power supply, remove the top cover and inspect the conductive tracks and contacts. The performance of radioelements is checked using a multimeter.

Depending on the cause of the breakdown, repairs may include:

• cleaning the board, removing oxides;
• checking, reconnecting, restoring wiring;
• replacement of individual elements or the entire module.

Bearing failure

Bearings ensure rotation of the drum during washing and spinning. As the seals wear out, water begins to get inside the parts, which leads to corrosion and their gradual destruction.Frequent use, drum overload and laundry imbalance lead to accelerated wear of the bearings.

The problem manifests itself as noise, vibration and displacement of the MCA at high speeds. Over time, the SMA completely stops rotating the drum. The problem can only be resolved by replacement.

To install a new spare part, you need to disassemble the tank, remove the pulley, knock out the bearings from their seats and install new ones. If the tank has a non-separable design, it is replaced entirely or cut and then welded. Due to the complexity of the work, replacement is most often carried out in a service center.

Features and cost of calling a professional technician

The cost of repairs at a service center starts from 1500-2000 rubles. in case of malfunctions of the UBL and tachometer and 3000-4000 rubles. in case of failure of the electronic module and bearings. The price of new parts is included in the estimate separately.

To avoid becoming a victim of scammers and unscrupulous craftsmen, necessary:

• study reviews about a company or specialist on city forums;
• check the actual legal address of the service and the date of registration of the legal entity;
• clarify the conditions for diagnostics and repair in advance;
• observe the work of the master (for example, it is impossible to draw a conclusion about the breakdown of the electronic unit without disassembling and checking with a tester).

Prevention

To reduce the risk of this error occurring, recommended:

1. Do not try to open the MMA door until operation stops completely and there is a characteristic click.
2. To protect the electronic control unit, install a relay or stabilizer in your home network, which will prevent voltage surges.
3. Check and replace bearing seals regularly.
4. When washing large items, place several towels to balance the drum.
5. 1-2 times a year inspect the wires and electronic board for contamination, clean oxidized tracks and contacts.
6. Do not lean on the open hatch or hang wet laundry on it.
7. Install the unit only on a flat surface without slope.

If extraneous noise, sparking or other signs of malfunction appear, you must immediately turn off the ACS and carry out diagnostics.

Conclusion

Error E07 can indicate either serious malfunctions (for example, damage to the control board or bearings), or an accidental failure or damage to the contacts, which you can fix yourself. To diagnose the most common breakdowns of a Candy machine, a home set of tools and a multimeter are enough.
