Gaggenau Dishwasher Error Codes Few people know that it is not always necessary to call a specialist, because malfunctions can be of a different nature and sometimes even suitable for self-repair. We are not talking about serious malfunctions, but anyone can offset the consequences of a blockage or replace a hose without outside help. The problem lies in the diagnostic capabilities of the average person who cannot determine the type of malfunction, so the manufacturer has added such a useful feature as the printout of error codes. Equipped with a special table and receiving information from the display of the Gaggenau dishwasher, you can easily understand what kind of problem is with the unit.
Gaggenau Dishwasher Error Code Solutions
| error code | reasons | Checking and Troubleshooting |
| E1 | Heating error | 1. Most often, this is a heating element malfunction – there is no resistance or leakage in the case. 2. The element in the electronic module responsible for the operation of the heating element is faulty. 3. Check the safety thermostat. 4. Check the flow sensor. 5. Check the pressure switch (water level sensor). |
| E2 | NTC sensor error (temperature sensor) | 1. The NTC sensor providing information to the PM control unit is faulty. As a rule, it is located in a block with a heating element, has a certain resistance (˜55kΩ at 21°C). |
| E3 | Water filling problems | If the desired water level has not been reached within a certain time. Depending on the model of the dishwasher (PM), the sequence of actions will be different. Either the PM will wait until the filling is complete (earlier models) or the water will drain for one minute (later models). 1. Defective Aquastop hose. 2. Defective water discharge pump. 3. Check the inlet valve. 4. Clogged inlet filter. 5. The pressure switch is faulty. |
| and 4 | Issues with the flow switch | Water flow switch is not in position. It is responsible for distributing water to the sprinklers and is mounted under the heating element. 1. Plugged switch. 2. Malfunction of the motor acting on the flow switch and adjusting it to one position or another. |
| E5 | Exceeding the fill level | 1. Pressure switch tube clogged. 2. Defective pressure switch (water level switch). 3. Defective inlet valve. |
| E6 | Aquasensor error | Aquasensor is an element that controls turbidity, hardness and water pollution at the first stage during rinsing. If the dishes are not very dirty, it eliminates rinsing and saves water and energy. It is located next to TEN. |
| E8 | Low water level in sump | Heating element does not turn on. There is not enough water pressure in the circulation pump and a pulse is sent to the module. Check the water pressure. Suspension is also possible. |
| E9 | Heating element error | Most often it happens in dishwashers with a flow heater built into the circulation pump, when the heating element breaks. Check the heating element for a break. |
| E11 | PMM works without heater | Check NTC sensor, electronics module, power cables. |
| E14 | Flow sensor error | The flow sensor does not detect control pulses as they are sent to the circulation pump. |
| E15 | Aquastop worked | A water leak has occurred. Check the water in the pot. The reasons for the leak can vary. |
| E16 | Unauthorized collection of water | Check inlet valve (flow sensor). Check the pressure switch (level sensor). One option is increased foaming. |
| E17 | Water filling error | Check flow sensor. It is also possible that the inlet pressure is too high. |
| E18 | Do not turn off the power. The program will end after the water is drained. | |
| E21 | Drain pump problems | Drain pump is clogged. Check the pump impeller for foreign body. If there is no clogging, the pump is probably worn and can sometimes jam during rotation – it needs to be replaced. |
| E24 | Water drain error | Dirty water drain hose is stuck or broken. |
| E27 | Low voltage in the network | Check the voltage at the socket. The error is more common during peak hours on city power grids, for example in the evening. Alternatively, install a voltage stabilizer. |
