Dishwasher Maintenance: Prevention and Care Guide

Dishwasher maintenance helps extend the life of the machine, improves washing quality, and prevents malfunctions. This article outlines the key preventive measures.

1. Filter Cleaning

Frequency: every 1–2 months. Remove and rinse under running water. A clogged filter worsens drainage and can overload the pump.

2. Spray Arm Cleaning

Frequency: once a month. Remove spray arms, clean holes with a toothpick or needle to remove limescale and food particles. Blocked holes reduce pressure and washing performance.

3. Use of Salt and Rinse Aid

Do not use table salt—it may contain impurities harmful to internal parts. Always use special dishwasher salt, which dissolves well and won't cause limescale.

4. Degreasing and Descaling

Use special cleaners every 1–2 months. Run an empty cycle with the cleaner. Alternatives include 1 cup of 9% vinegar or 2–3 tablespoons of citric acid, but limit to once every 2 months as acids may damage seals.

5. Cleaning Seals and Door Frame

Every 2 weeks, wipe seals and door joints with a cloth soaked in vinegar or mild detergent. Grease and mold can accumulate in hidden crevices.

6. General Operating Tips

• Don't overload the machine
• Arrange dishes properly; don't block spray arms
• Remove large food scraps before loading
• Don't run the machine without water
