How to Use and Adjust a Home Coffee Machine

If you’ve just bought a coffee machine, you’re probably wondering how to actually use it — how to fill it with water, change the taste, set the price, or even what to do when the lights blink at you. This guide explains everything you need to know, from first use to fine-tuning, with exact steps and controls.

To start using your coffee machine, plug it in, turn it on, and wait for the green ‘ready’ light. Fill the water tank without tilting it, ensure the paper cup supply is full, and wait until the heating cycle finishes. Only then can you insert coins and select a drink. That’s the basic workflow.

1. Filling Water and Adding Supplies

Before using the machine, make sure the water bucket isn’t tilted. Plug the power cord into the socket and turn the machine on. Then check the status lights:

• Please add cup (red light): means paper cups are empty. Refill with new cups, ensuring they are not deformed.
• Please add water (red light): indicates low water level. Refill with fresh water.
• Please heat (red light): shows the water is not hot enough. Wait while it heats — the machine won’t accept coins during this.

Once the ‘please use’ (green) light turns on, the machine is ready. Insert coins, choose your coffee type, press the button, and wait for the automated process: the machine will drop a cup, release the coffee, and signal readiness with a beep or when the yellow light above the coin slot goes off.

2. Using the Counter

The built-in counter tracks usage. To check it:

• On startup, the current count is shown on the digital display as it scrolls.
• You can also open the machine door while powered on, press the counter button, and view the rolling value on the digital panel.

3. Setting the Drink Price

To adjust pricing:

• Open the machine door and set the mode switch to ‘on’.
• Press the price button to adjust the cost of drinks as desired.
• When finished, turn the mode switch back to ‘off’ to save the settings.

4. Adjusting Coffee Taste

Taste adjustments are made inside the machine too:

• Open the door, turn the mode switch to ‘on’, and press the button for the drink you want to modify.
• Use the flavor concentration adjustment buttons (for powder) on the right side to increase or decrease intensity.
• Once you're satisfied, switch the mode back to ‘off’ to lock in the new taste profile.

What to Watch When Filling

Always keep the water tank level and avoid tilting it. Also, ensure that the paper cups are not damaged before reloading. Using distorted cups could affect dispensing or lead to jams.

Why the Lights Matter

The red and green status lights are not just decorations — they tell you exactly when the machine is ready to use. Never insert coins when a red light is on, or your money will be ejected. Wait for the green ‘use’ light before making a selection.

How the Coin and Selection System Works

Coin insertion only works when the machine is fully ready (green light). Once accepted, you choose your drink via buttons, and the machine automates the rest — from cup drop to serving. Timing is key: wait for either the ‘drop’ sound or the yellow light to go off before taking your drink.

Frequently Asked Questions

What should I do if the coffee machine doesn't accept my coins?

If the coin is rejected, check the status lights. A red light means the machine is not ready — it may need water, cups, or more heating time. Only insert coins when the green 'please use' light is on, indicating normal operation.

How do I know when the machine is ready to make coffee?

Wait for the green ‘please use’ light to illuminate. This means the machine has water, cups, and is heated. Only then can you insert coins, choose a drink, and begin the automated process.

Can I adjust how strong the coffee tastes?

Yes. Open the machine door, switch the mode to ‘on’, press the button for the drink you want, and use the right-side concentration adjustment buttons to change the strength. Lock in your preferred taste by switching the mode back to ‘off’.

How do I check how many drinks the machine has served?

The internal counter displays the number on the digital screen. You can view it upon startup or by opening the door while powered and pressing the counter button.

How do I change the price of drinks on the machine?

Open the machine door, turn the mode switch to ‘on’, and press the price button to adjust up or down. Confirm your price, then turn the mode switch back to ‘off’ to save.

What happens if I add water or cups while the machine is on?

You can refill both water and cups at any time, but only when the respective red warning light is off and the machine is in standby or ready mode. Avoid refilling during heating or when the ‘no cup’ or ‘no water’ red indicators are lit.
