If you have a dishwasher at home and instead of the usual symbols on its display you see strange numbers, then perhaps this is a signal of a malfunction. Home appliance repair specialists also face similar problems. To figure out what's wrong, you need to know the equipment manufacturer and the error coding system they use. The operating instructions most often describe how to decipher a particular numerical value that appears on the screen. Error e1 in Hansa dishwasher means that there is a problem with the intake and drainage of water.
Reasons for the error
There may be several reasons, but they are all related to the circulation of liquid in the working area of the device, or to a malfunction of the electrical components of the passage control system:
- Insufficient or excessive pressure.
- Clogged inlet filter in front of the inlet valve.
- Problems with drainage.
- Failure of the intake valve itself.
- Flow sensor failure.
Troubleshooting methods
Change in line pressure
The manufacturer has designed it in such a way that the flow sensor in dishwasher Hansa is set to a specific pressure range of 2.5 to 6 atmospheres, which is most often provided in the highways of residential complexes.Error code e1 is diagnosed when there is a deviation both upward and downward.
When there are surges in water pressure, if you are not going to just wait for everything to stabilize by itself, experts recommend installing an adjustable pressure relief valve that compensates for the change in pressure and your dishwasher will work with the parameters set by the manufacturer.
Problems with filter and inlet valve
These two parts are next to each other, so it makes sense to clean and check them as a pair. Before doing this, do not forget to turn off the power to the machine and turn off the water supply. First of all, it is necessary to dismantle the intake mechanism along with the hose. To do this you need to unscrew one end intake hose from the body, and the other from the water main fitting.
The filter is located near the intake site and has the appearance of a thin fine-mesh mesh. We thoroughly clean the mesh and hose from any deposits that may have been caused by water. If the filter is damaged, it is better to replace it, as it prevents clogging of internal elements, which are much more expensive and vulnerable to contamination.
The valve itself is checked for the integrity of the electrical circuit using a conventional tester. If the test gives a positive result, then we assemble the assembly in the reverse order - first we insert the flow element, then we connect the assembly to the hose and connect the body and the water main tee. It's worse if the valve fails.
Checking the drain
The next step is to check the functioning of the drain in the Hansa dishwasher.Violation of the normal draining mode will result in error e1 constantly appearing on the screen and the dishwasher will be unusable. To do this you need to do the following:
- unlock the hopper lid;
- pull out the lower basket;
- unscrew the drain element and clean it from the applied dirt;
- Unscrew the screws holding the seat;
- pull out the flap;
- check the possibility of free rotation of the impeller and the presence of debris in the rotation zone, clean the blades from possible plaque and dirt.
If after all these manipulations the machine does not display error e1, then the reason was the poor functioning of the drain system.
Checking the flow sensor
Another option that can be identified as the cause of error e1 is a malfunction of the flow sensor. On the Hansa dishwasher it is located behind the side wall on the left edge.
If this does not help, then most likely the sensor is faulty and needs to be replaced. Electronic spare parts of this kind cannot be repaired due to their design. Just don’t forget to take a photo of the connection diagram, otherwise you’ll spend more time installing the new element than necessary.
If, after all your attempts, error e1 continues to appear in your Hansa dishwasher, then it would be a wise decision to consult a specialist who will tell you what to do.
Modern household appliances designed so that minor repairs or replacement of consumables can be performed by almost anyone. As a rule, such cases are described in detail in the operating instructions.Complex repairs are carried out in specially equipped workshops and are done by professionals with extensive experience.
