High-Efficiency Dishwasher: Common Issues and Solutions

A high-efficiency dishwasher is a modern kitchen appliance that uses less water and energy while providing superior cleaning performance. These dishwashers have advanced features like multiple spray arms, sensor-based washing cycles, and energy-saving modes. However, like any appliance, they may encounter issues over time. This article explores how they work, common problems and their solutions, essential parts and their functions, and the costs of repairs, including labour and spare parts.

How High-Efficiency Dishwashers Work

A high-efficiency dishwasher cleans dishes in stages:

1. Water Intake: It draws water through a water inlet valve and heats it using a heating element.
2. Washing Cycle: Spray arms powered by a pump distribute water mixed with detergent to clean dishes.
3. Rinse Cycle: Dishes are rinsed with clean, hot water.
4. Drying Cycle: Heated air or condensation drying removes moisture from dishes.

The dishwasher’s sensors and microprocessors ensure water, detergent, and energy are used optimally.
