Frequently Asked Questions - 10304 KORONA

How do I descale my Korona 10304 coffee maker?

Mix equal parts white vinegar and water and fill the tank. Run a brew cycle without coffee grounds, then run two cycles with fresh water to rinse.

What type of filter does this coffee maker use?

It uses a permanent filter (included) or standard paper filter No. 4.

Why is my coffee weak?

Possible reasons: too little ground coffee, too coarse grind, or machine needs descaling. Use about 1 tablespoon per cup and a medium grind.

How do I clean the carafe?

Wash the glass carafe with warm soapy water and a soft sponge. Avoid abrasive pads to prevent scratches.

Can I brew tea in this machine?

Technically yes, but it's not recommended as coffee oils may affect taste. Use a paper filter and choose an appropriate tea.

Why does my coffee maker leak?

Check if the carafe is properly positioned, the filter basket is correctly inserted, or the anti-drip valve is stuck. Clean and reposition.

How long does a brew cycle take?

A full carafe (1 liter) takes approximately 10 to 12 minutes.

Does the keep-warm plate stay on permanently?

No, it has an automatic shut-off after 2 hours for safety.

Can I use pre-ground coffee?

Yes, any medium-ground drip coffee works. Avoid very fine or coarse grinds.

Where can I buy spare parts?

Check the Korona website or authorized service centers. Common parts like carafe and filter basket are available online.
