How do dishwasher dispenser doors and timed release mechanisms work? Detailed guide

What is a dishwasher dispenser door and why is it important?

When using the dishwasher we often find that the detergent or rinse aid capsules open automatically at certain times. This automatic process is controlled by a detergent dispenser door and a timed release mechanism.

This system performs three main functions:

• Timely release of detergent: Ensures that the detergent is fully effective as soon as the dishwasher’s wash cycle begins.
• Slow release of rinse aid: Releases the rinse aid slowly before the end of washing so that the dishes are sparkling.
• Saving water and energy: Controls wastage by using unnecessary detergent or rinse aid.

Dispenser Door Structure and Main Parts

A typical dishwasher dispenser door usually consists of the following parts:

1. Detergent dispenser

It is generally of two types:

• Powder/Gel Dispenser: Found on most older models. Detergent powder or gel is kept here.
• Tab/capsule dispenser: Used in modern dishwashers. Pre-measured detergent tabs or capsules are kept here.

2. Rinse aid dispenser

It is usually located at the top of the dishwasher. Rinse aid is released slowly to keep dishes clean and sparkling.

3. Timed Release Mechanism

This mechanism is basically controlled by a timer-controlled latch system or a magnetic release system. This determines when the door will open and the detergent or rinse aid will be released.

4. Water inlet valve

This valve controls when water enters the dishwasher and rinses the detergent.

How does the timed release mechanism work?

The timed release mechanism works in three steps:

Step 1: Before the wash cycle starts

When the dishwasher is turned on, the timer system starts. Most dishwashers have this timer:

• Electronic Timer: Controlled by digital control panel.
• Mechanical timer: Seen in older models, which rotates like a clock.

As soon as the timer starts, the latch system locks the door to prevent the detergent from being released.

Step 2: During the wash cycle

The timer opens the door at specific times during the dishwasher’s wash cycle. Usually:

• Initial wash cycle: Detergent is released after the first 10-15 minutes of opening the door.
• Main wash cycle: After another 20-30 minutes the rinse aid is released.

This time is determined according to the program setting of the dishwasher.

Step 3: Before the wash cycle ends

In the final step, the timer slowly releases the rinse aid to keep dishes clean and sparkling. The dishwasher then turns off automatically.

Types of Timed Release Mechanisms

A variety of timed release mechanisms are available in the market. Some of the main ones are:

1. Magnetic Release System

This system uses an electromagnet which opens the door at a certain time. It is reliable and works quickly.

Example: This technology is used in Bosch 800 Series dishwashers.

2. Timer-controlled latch system

This system uses a mechanical timer which opens the latch at specific times. This is more common in older models.

Example: This technology is used in the Whirlpool WDT710PAHZ model.

3. Sensor-Based Release System

Modern dishwashers use sensors which determine the detergent release time according to the amount of dirt on the dishes.

Example: The Samsung DW80R9950US model uses this technology.
