| E3 | Not getting enough liquid. | Check: 1. Clogged filter. 2. Operation of the fill valve. 3. Status of the water level detector. 4. Operation of the drain pump. |
| F3 | Insufficient amount of water. | It is recommended to check: the correctness of the water level detector; no blockage in the water filter; water inlet valve; drainage pump. |
| E5 | Excessive water level. | Needs checking: contacts and wiring of the water level sensor, control system (diagnostics in the service), correct operation of the filling valve. |
| F5 | Too high water level. | It is recommended to check the serviceability of the filling valve, the connection of the water level sensor with the control board, the control unit (diagnostics will be required). |
| E8 | Low fluid level. | The water does not heat up due to the low level. Must check: liquid level meter; the correct operation of the valve; Doesn't the water run off by itself? |
| F8 | Insufficient liquid. | No water heating due to low level. You need to see if the water is draining by gravity. It is necessary to check the level sensor and the operation of the drain valve. |
| E16 | Uncontrolled level of the aquatic environment. | 1. It is necessary to check the valve, clean it from blockage. 2. The level detector is checked. Failure may be repeated due to excessive foam. |
| F16 | The flow of liquid is not controlled. | Valve clogged or malfunctioning. The level meter is out of order. The recurrence of the problem is the formation of a large amount of foam. |
| E17 | Gulf problem. | The fault is related to the closing of the valve. 1. Increased water pressure. 2. Water hammer - solved by restarting the system. 3. The level sensor is out of order. |
| F17 | Water is pouring with a problem. | Associated with incorrect operation of the valve due to: 1. Increased water pressure. 2. Water hammer (requires restart). 3. Breakdown of the level detector. |
| E21 | Drain pump defective. | If there is no open circuit and the pump is working, then the reasons are: 1. The impeller of the pump is clogged. 2. Pump wear. Requires replacement. 3. The walls of the hub are stuck to the rotor. |
| F21 | Drain pump problem. | In the absence of an open circuit and a working pump: 1. The impeller is jammed due to blockage. 2. The pump is defective and needs to be replaced. 3. The rotor has stuck to the wall of the hub. |
| E07 | Blockage in the drain system. | Causes: 1. The dishes are placed in such a way that they close the drain passage. 2. The drain system is clogged with debris. Recommendation: clean the drain hole. |
| F07 | Drain clogged. | Several reasons for the occurrence: 1. Pawning dishes close the water drain hole. 2. Clogged drain hole with debris or foreign objects. |
| E22 | Filter dirty. | 1. The filter is dirty. 2. The operation of the drain pump is difficult, which is expressed in the difficult rotation of the impeller blade. Blades need to be checked. |
| F22 | The filter is dirty. | 2. The filter is dirty. Needs cleaning. 2. Difficult rotation of the impeller blades during operation of the drain pump. Inspection required. |
| E24 | Drain hose problem. | 1. Perhaps there was a crease or bend in the drain hose. 2. The sewer was blocked. 3. The drain outlet of the siphon was blocked. |
| F24 | Drain problems. | 1. Siphon outlet clogged. Needs to be cleaned. 2. For some reason, there was a bend / crease in the drain hose. 3. Possibly blocking the sewers. |
| E25 | Clogged drain pump nozzle. | To eliminate: 1. Clean the pipe from dirt. 2. Clean the drain hose. 3. Check the integrity of the impeller. |
| F25 | Clogged pump nozzle. | The problem is eliminated: 1. Cleaning the drain hose. 2. Cleaning the pipe from foreign objects. 3. Checking the health of the impeller. |
| E4 | Flow sensor defective. | Possible cause: due to hard water, the sprinkler nozzles are clogged. As a result, difficult water supply to the drum. |
| F4 | Problem with flow sensor. | The reason arises from a hard water environment that has clogged the sprinkler nozzles. Thus, water does not enter the drum well. |
| E6 | Faulty purity sensor. | The element is next to the electric heater. If the sensor is defective, it must be replaced. Otherwise, check the electrical. |
| F6 | The problem with the purity sensor. | This item is located next to the electric heater. It is necessary to check the serviceability of the sensor, replace if necessary. Also, check the electrical. |
| E14 | Problem with water meter. | The sensor needs to be checked to see if it works. If the element is defective, it must be replaced with a new element. |
| F14 | Volume detector defective. | It is recommended to check the performance of the water volume meter. If the sensor is defective, it must be replaced with a new one. |
| E15 | A leak has occurred. | Check for moisture in the pan. Inspect the integrity of the system hoses and troubleshoot. If no leak is found, inspect other system components. |
| F15 | A leak. | If there is moisture in the pan, then it is necessary to inspect the system hoses for penetration. If no leak is found, inspect the remaining elements in the system. |
| E27 | Voltage drop. | Occurs when the voltage in the electrical network is unstable. The problem is fixed by using a third-party voltage regulator. |
| F27 | Unstable voltage. | There is a voltage drop in the mains. To fix the problem, you must install a voltage stabilization device. |
