What to check first

Brewer type and filter type

Your Ratio 6 is a pour-over style brewer. It uses specific paper filters designed for its basket. Make sure you’re using the right ones. Using the wrong filter can mess with water flow and extraction.

Water quality and temperature

Good coffee starts with good water. If your tap water is hard, it’ll leave mineral deposits faster. Consider a water filter for your tap or reservoir. The machine heats the water, but starting with good water helps.

Grind size and coffee freshness

The Ratio 6 is designed for a medium grind. Too fine, and it might clog. Too coarse, and your coffee will be weak. Always use freshly roasted, freshly ground beans. Old coffee just tastes stale, no matter how clean your machine is.

Coffee-to-water ratio

This machine is built for precision. Follow the recommended ratios for the best results. Too much coffee can lead to over-extraction and bitterness. Not enough, and it’ll be watery. Check the manual for their sweet spot.

Cleanliness/descale status

This is the big one. Mineral buildup is the enemy of any coffee maker. If you’re tasting off-flavors or seeing slow brew times, it’s probably time to descale. Regular cleaning prevents bigger problems.

Step-by-step (brew workflow)

Here’s how to get your Ratio 6 sparkling:

1. Empty the grounds and filter: After each brew, toss the used grounds and filter.

• Good looks like: A clean brew basket, no stray grounds.
• Common mistake: Leaving grounds in the basket. This can lead to mold and affect the next brew. Just scoop ’em out.

2. Rinse the brew basket and carafe: Use warm water and a little dish soap.

• Good looks like: A shiny, residue-free basket and carafe.
• Common mistake: Not rinsing thoroughly. Soap residue can make your coffee taste weird.

3. Wipe down the showerhead: Use a damp cloth to gently wipe the showerhead area.

• Good looks like: No visible coffee grounds or mineral deposits.
• Common mistake: Letting coffee oils build up here. It can drip into your cup.

4. Clean the exterior: A quick wipe with a damp cloth keeps it looking sharp.

• Good looks like: A smudge-free, clean machine exterior.
• Common mistake: Using harsh chemicals. Stick to a damp cloth to avoid damaging the finish.

5. Run a water-only cycle: Fill the reservoir and run a brew cycle with just water.

• Good looks like: Clear water flowing through the machine.
• Common mistake: Skipping this after washing. It ensures no soap or cleaning solution residue remains.

6. Prepare for descaling: Empty the reservoir and remove any grounds or filters.

• Good looks like: A clean slate, ready for the descaling solution.
• Common mistake: Forgetting to remove the filter. It’ll just get soaked.

7. Add descaling solution: Follow the instructions on your descaling product or use white vinegar. Ratio recommends specific solutions, but vinegar is a common alternative. Dilute as instructed.

• Good looks like: The correct amount of solution mixed with water in the reservoir.
• Common mistake: Using too much or too little solution. Too much can be harsh; too little won’t clean effectively.

8. Run a descaling cycle: Start the descaling cycle as per your Ratio 6 manual. This usually involves running the full brew cycle with the solution.

• Good looks like: The machine runs through its brewing process, flushing the internal components.
• Common mistake: Interrupting the cycle. Let it complete fully to ensure all parts are flushed.

9. Discard the solution: Once the cycle is done, discard the descaling liquid.

• Good looks like: The reservoir is empty and the machine is ready for rinsing.
• Common mistake: Leaving the descaling solution in the machine.

10. Run multiple rinse cycles: Fill the reservoir with fresh, clean water and run at least two full brew cycles.

• Good looks like: Only clear water comes out. No soapy or vinegary smell or taste.
• Common mistake: Not rinsing enough. This is crucial to remove any lingering descaling taste.

11. Clean the water reservoir: If you see any film or buildup, remove the reservoir and wash it with soap and water.

• Good looks like: A clear, clean reservoir.
• Common mistake: Neglecting the reservoir itself. It’s where your water sits.

12. Reassemble and wipe down: Put everything back together and give the machine a final exterior wipe.

• Good looks like: A clean, fully functional coffee maker.
• Common mistake: Rushing the reassembly. Make sure all parts are dry and in place.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Not descaling regularly	Slow brew times, weak coffee, machine eventually clogs and fails	Run a descaling cycle with a proper solution every 1-3 months, depending on water hardness.
Using tap water without filtering	Rapid mineral buildup, affecting taste and machine performance	Use filtered or bottled water; consider a water filter for your tap.
Leaving wet grounds in the brew basket	Mold growth, unpleasant odors, potential contamination of future brews	Empty and rinse the basket immediately after each brew.
Using incorrect or old coffee filters	Poor water flow, under or over-extraction, grounds in your coffee	Use only Ratio-approved filters; check they are seated correctly.
Using pre-ground coffee that’s too fine	Clogging of the filter, channeling, bitter and over-extracted coffee	Use a medium grind; grind beans right before brewing for best results.
Not rinsing after using cleaning solutions	Lingering chemical or vinegar taste in your coffee	Always run at least two full water-only cycles after descaling or cleaning.
Ignoring strange noises or slow drips	Potential internal clogs or failing components, leading to bigger repairs	Address any unusual behavior promptly; check for blockages or leaks.
Using harsh cleaning chemicals	Damage to machine parts, plastic, or finishes; potential for toxic residue	Stick to approved descaling solutions, white vinegar, mild soap, and water.
Not cleaning the showerhead	Clogged spray holes, uneven water distribution, coffee oil buildup	Wipe the showerhead area regularly and descale to ensure clear flow.
Overfilling the water reservoir	Potential for overflow or inconsistent brewing temperature	Fill to the indicated max line only.

Decision rules (simple if/then)

• If your coffee tastes bitter, then check your grind size and coffee-to-water ratio because these directly impact extraction.
• If your brew time is significantly longer than usual, then it’s time to descale because mineral buildup is likely slowing water flow.
• If you see white, chalky deposits in the water reservoir or on the showerhead, then you need to descale immediately because this is hard water buildup.
• If your coffee tastes “off” or stale, then check your coffee freshness and grind size because these are the most common culprits.
• If you’re unsure about the descaling solution, then check the Ratio 6 manual or contact their support because they have specific recommendations.
• If you notice any drips or leaks from the machine, then stop using it and check for obvious blockages or loose parts because water damage can be serious.
• If the brewed coffee has grounds in it, then check your filter type and ensure it’s seated properly because this indicates a breach in the filtration.
• If the machine is making unusual grinding or straining noises, then it might be a sign of a clogged pump or heating element and you should consider descaling or professional service.
• If you’ve recently descaled and the coffee still tastes off, then run more rinse cycles because residual cleaning solution can affect taste.
• If your water is particularly hard, then plan to descale more frequently than the general recommendation because hard water causes faster buildup.
• If you’re using a new coffee bean, then adjust your grind size and ratio because different beans require different parameters.

FAQ

How often should I descale my Ratio 6?

It depends on your water hardness and how often you use the machine. A good rule of thumb is every 1-3 months. If you notice slower brew times or a change in taste, it’s probably time.

Can I use regular white vinegar to descale?

Yes, white vinegar is a common alternative if you don’t have a dedicated descaling solution. Use a 1:1 ratio of white vinegar to water. However, always run several water-only cycles afterward to remove any lingering vinegar smell or taste.

What kind of filters does the Ratio 6 use?

It uses specific paper filters designed for its brew basket. Always check your manual or the Ratio website for the exact filter type to ensure optimal performance.

Is it okay to leave the brew basket in the machine when not in use?

No, it’s best to remove and rinse the brew basket after each use. Leaving wet grounds can lead to mold and unpleasant odors.

How do I know if my coffee is being extracted properly?

Proper extraction usually results in a balanced flavor – not too bitter (over-extracted) and not too sour or weak (under-extracted). The aroma should also be rich.

What if my coffee tastes burnt?

A burnt taste often means over-extraction. This can be caused by too fine a grind, too hot water (though the Ratio 6 controls this well), or too long of a brew time. Check your grind size first.

Can I use soap to clean the carafe and brew basket?

Yes, mild dish soap and warm water are fine for cleaning the carafe and brew basket. Just be sure to rinse them thoroughly to remove all soap residue.

How do I clean the water reservoir?

The water reservoir can usually be removed. Wash it with warm, soapy water and rinse well. If you see any mineral buildup, a gentle scrub with a soft brush can help.
