FAQ
Common questions
How often should I descale my coffee maker?
In hard water areas (water with high mineral content), descale every 1-3 months. In soft water areas, every 3-6 months is adequate. Most modern coffee makers have a descale indicator light that triggers based on brew cycle count, use it as a minimum, not a maximum. If your coffee takes longer to brew or the machine makes unusual sounds during brewing, descale regardless of the indicator.
Can I use vinegar instead of descaling solution?
White vinegar works as a descaling agent and is less expensive than branded solutions. The tradeoff is that vinegar requires more rinse cycles to fully clear the taste and smell. Use a 1:1 ratio of white vinegar to water, run the full brew cycle, then run two to three full cycles with pla in water. Some manufacturers void warranties if vinegar is used, check your manual.
Why does my coffee maker brew slowly after descaling?
Slow brewing after descaling usually means scale was not fully removed, or the descaling solution was not adequately rinsed out. Run additional pla in water cycles. If slow brewing persists, the scale may require a second descaling treatment with a stronger solution or longer soak time.
