Gaggenau dishwashers errors, decoding

Error code Description Causes and solution
E1 Heating fault.1. Non-working heating element. 2. Breakdown of the protective thermostat. 3. The pressure switch is faulty. 4. Non-working flow sensor. 5. There is no connection between the heater and the board.
E2 Failure of the temperature meter.The sensor needs to be checked with a multimeter - the resistance of the element should be within 55 kOhm at a temperature of 21 ° C.
E3 Faulty filling system.1. The drain pump is not working. 2. The inlet valve is out of order. 3. The filter is clogged. 4. The pressure switch is defective. 5. Incorrect operation of the "Acqua Stop" hose.
E4 The flow switch is defective.1. Switch clogged. 2. Faulty motor acting on the flow switch, which should set it to the desired position.
E5 Level issue.1. Faulty water level meter (pressure switch). 2. The inlet valve is out of order. 3. Foreign objects entering the pressure switch tube.
E6 Aquasensor problem.The element is located near a tubular heater that monitors water quality (including pollution), which saves water and electricity.
E8 Low fluid level.The heater does not turn on. The pump reports the low water level to the control board. It is necessary to check the pressure of the water supply and the absence of self-draining.
E9 The electric heater has failed.To eliminate the cause of the malfunction, it is necessary to check: - the connection of the electric heater with the control board; - the health of the heater.
E11 There is no water heating.It is recommended to check: 1. The efficiency of the heating sensor. 2. Communication of the measuring sensor with the control board. 3. Control board.
E14 The flow sensor is defective.The main board does not receive data from the flow sensor, but the circulation pump continues its normal operation, receiving certain signals.
E15 Aquastop work.Water leak detected. There is moisture in the pan. The causes of leakage can occur both in the tubes themselves and in the tightness of their connection.
E16 Uncontrolled intake of water.Need to check: - inlet valve (flow sensor); - water level meter; - Causes of increased foaming.
E17 Water filling problem.It is necessary to check the correct operation of the flow sensor. Also, the cause may be the high pressure of the main water supply.
E18 Warning.The control board informs that there is no need to turn off the power - the system will automatically shut down when the water is drained.
E21 Pump failure.The pump impeller has become blocked due to foreign objects, which makes it impossible to perform work. In another case, the motor is worn out, a replacement is necessary.
E24 Waste water is not drained.It is impossible or difficult to drain the liquid from the hopper. It is recommended to check the absence of creases (or bends) in the pipes of the contaminated liquid drain system.
E27 Reduced voltage.The malfunction occurs due to the low voltage of the electrical network. For stable operation, use a voltage stabilizer.
