A mid-to-high-end Bosch, Siemens, or Electrolux dishwasher costs between 18-50 million VND. This is a significant investment, so proper dishwasher maintenance is crucial for it to operate smoothly for 10-15 years instead of breaking down after 3-4 years.
1. Golden rule: a complete set of 3 standard EU accessories
For all dishwasher models imported from Germany, Turkey, or China (Bosch SMS6, Siemens iQ500, Electrolux ESF, Hafele HDW…), manufacturers recommend using all three types of products:
- Dishwasher tablets
- Specialized salt
- Rinse aid
In reality, most issues like "noisy machine," "dishes not clean," or "dishes not dry" stem from not using the complete set or using low-quality products. These are not technical machine faults.

2. Regular maintenance schedule
2.1. Weekly
- Remove the bottom filter, rinse under warm water – remove food debris.
- Wipe the door gasket and cavity edges with a damp cloth – prevent mold.
- Check both spray arms, clean the spray holes.
2.2. Monthly
- Check the salt compartment lid – ensure it's tightly closed to prevent saltwater overflow.
- Check the rinse aid level, adjust the dispensing amount if dishes are still wet.
- Wipe the control panel with a soft cloth, do not use alcohol.
2.3. Every 3-6 months
- Run the self-clean / machine care program – remove grease and lime scale buildup in the cavity.
- Check the water inlet hose – ensure it's not kinked or leaking.
- Clean the salt compartment with clean water, prevent salt from clumping at the bottom.
3. Mistakes to avoid
| Mistake | Consequence |
|---|---|
| Using hand dishwashing liquid | Foam overflow, pump damage, poor washing performance |
| Not using specialized salt | Lime scale on heating element, sensor damage |
| Using table salt instead of dishwasher salt | Impurities damage resin beads |
| Not cleaning the bottom filter | Bad odor, clogged drain |
| Using low-quality dishwasher tablets | Chemical residue accumulates in the detergent compartment |
4. Standard accessories for Bosch / Siemens / Electrolux dishwashers
Bosch Series 4/6/8 and Siemens iQ500/iQ700 models perform best with EU-standard dishwasher tablets – popular choices include Largo products directly imported from Germany:
- Largo Classic Dishwasher Tablets 60 tablets – powerful formula, suitable for machines already using the complete set of 3.
- Largo All In One Dishwasher Tablets 40 tablets – convenient, 7-in-1.
- Largo Salt 2kg – compatible with all standard EU salt compartments.
- Largo Rinse Aid 1L – designed for standard EU machines.
5. Tips to extend machine lifespan
- Always leave the door ajar for 10-15 minutes after washing to release moisture and prevent mold.
- Avoid washing when room temperature is too low (<10°C) → tablets may not dissolve completely.
- Prioritize using Eco/Auto mode – saves electricity + protects the machine.
- Once a year: call a technician for deep cleaning of the machine cavity and inspection of pump bearings.
6. Conclusion
Dishwasher maintenance is not difficult – the key is to understand the principles and use the correct standard accessories. If you've invested tens of millions in a Bosch / Siemens / Electrolux machine, further invest a few hundred thousand VND/month in a set of standard German accessories – this is the cheapest "insurance" for your asset.
