Does the Hansa dishwasher display an error code E1 on the display? This means that the self-diagnosis system has detected a malfunction during the collection and discharge of 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 model of dishwasher.
Why does the error appear, and how to get rid of it yourself?
The value of the code E 1 and ways to resolve it
The dishwasher “Hansa” can show the E1 badge on the board in case of problems with filling and draining water: it is not possible to dial enough, a bad pressure. If you follow the decoding, then you need to look for malfunctions in the flow sensor, filling or drain path.
What to do in such a situation? Check one by one. A flow sensor is installed in some Hansa PMM models instead of a pressure switch and controls the amount of water in the hopper. If it is incorrectly read, the module does not send a signal to the systems for collecting or draining water.
The flow sensor is checked first. If it is faulty, the element is replaced.
After the diagnosis, an error appeared again? Try to reset it by rebooting the machine. To do this, disconnect from the network for 10-15 minutes. After restarting, look at the screen. If the code disappeared, then the cause was a system failure. But if the icons light up again, check the drain and filler systems.
How to fix the problem:
- Close the shut-off valve.
- Disconnect the intake hose from the inlet of the PMM.
- Inspect the hose and strainer behind it: if there is any blockage.
- Remove the blockage, wash 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.
- Remove the screws around the filter seat.
- Pull the shutter toward you and remove it.
- Check the impeller and remove debris that may block its operation.
Your manipulations did not help to eliminate the error code E1? So, it is better to contact the master. There are many reasons for the failure, you may need to repair or replace parts, check the drain pump.
