Another factor that can trigger the descaling light is when refillable K-cups are used and packed too tightly, causing water flow restriction within the machine.

It is recommended that users descale their coffee machines regularly to remove any mineral buildup and use refillable K-cups with a moderate amount of coffee grounds to ensure proper water flow to prevent such occurrences. Neglecting these maintenance practices can result in the machine breaking down, leading to costly repairs or replacements.
