Keurig Coffee Maker Problems

Coffee not brewing

Troubleshooting Steps for When the Machine Won’t Brew

  • Check Water Reservoir: Ensure that the water tank is filled with enough water for brewing. If the water level is low, the machine may not initiate the brewing process.
  • Examine Power Connection: Verify that the coffee maker is properly plugged in and the power button is switched on. A loose power connection can prevent the machine from starting.
  • Clean the Needle: A clogged needle can obstruct the flow of water through the K-Cup. Carefully remove the K-Cup holder and clean the needle to ensure it’s free from any coffee grounds or debris.
  • Descale the Machine: Mineral build-up in the water lines can hinder the brewing process. Run a descaling cycle using a descaling solution or vinegar to remove any scale deposits.
