Does your Hansa dishwasher show error code E1 on the display? This means that the self-diagnosis system has detected a problem in the process of collecting and draining water. To find out exactly where to look for a breakdown, you will need to decrypt the code. It is indicated in the instructions for your dishwasher model.
Why does the error appear, and how to get rid of it yourself?
The meaning of code E 1 and ways to eliminate it
The Hansa dishwasher can show the E1 icon on the display in case of problems with filling and draining water: it is not possible to draw enough, poor pressure. If you follow the decoding, then faults should be sought in the flow sensor, filler or drain path.
What to do in such a situation? Check everything one by one. The flow sensor is installed in some Hansa PMM models instead of the pressure switch and controls the amount of water in the hopper. If it reads incorrectly, the module does not send a signal to the systems for collecting or draining water.
First of all, the flow sensor is checked. If it is defective, the element is replaced.
After the diagnosis, the error appeared again? Try resetting it by restarting your machine. To do this, disconnect from the network for 10-15 minutes. After restarting, look at the screen. If the code disappeared, then the reason was a system failure. But if the icons are on again, check the drain and fill systems.
How to fix the problem:
- Close the stop valve.
- Disconnect the intake hose from the PMM inlet.
- Inspect the hose and the mesh filter behind it for blockage.
- Remove the blockage, rinse the parts under the pressure of water.
Next, check the drain:
- Open the hopper door.
- Remove the lower basket.
- Unscrew the drain filter. Rinse it under the tap with a brush.
- Loosen the screws around the filter seat.
- Pull the flap towards you and remove it.
- Check the impeller and remove debris that may be blocking its operation.
