A dishwasher can be rendered almost useless if not heating up correctly. If you notice that after the washing process is complete and your dishes are still wet, cold, and have stains, then this means that the hot water system for your device is faulty. Siemens dishwasher does not heat water.
How to realize an indication of malfunctioning in a dishwasher
First, you should pay close attention to the temperature and the condition of the dishes. If you notice that the plates are not clean and cold, then it shows that there are faulty parts. It also indicates that the water temperatures are below the expected heat amount.
There are three significant causes of why the water is not heated up correctly:
- Faulty heating equipment
- Malfunctioning temperature sensors
- Defective control unit
To diagnose which among this equipment is at fault, you need to detach the dishwasher. Through the use of a multimeter determine the continuity across the NTC and the heating component. Since there is no quick fix to this issue, such a problem requires that you first troubleshoot the specific issue and later can call out an engineer to help you in fixing the dishwasher.
