coffee machine not dispensing coffee

  • Why is my coffee machine not dispensing coffee or water?

    If your coffee machine is not dispensing, the most common causes are a blocked brew unit, limescale restricting water flow, a failed pump, a jammed grinder, an airlock in the system, or a solenoid valve fault. Many machines will also display a fault code when flow is restricted.

    Check Water Tank

    • Remove and reseat
    • Ensure valve opens
    • Confirm tank is full

    Run a Hot Water Cycle

    If water dispenses from steam wand but not coffee spouts, issue may be brew unit related.

    Clean the Brew Unit

    • Remove (if removable)
    • Rinse under warm water
    • Allow to dry completely

    Descale the Machine

    Limescale is one of the most common causes of flow restriction.

    Check Bean Hopper

    Stir beans

    Remove oily beans

    Clean grinder chute (if accessible)

  • Most Common Causes

    Blocked Brew Unit

    • Coffee oils build up
    • Grounds compact inside chamber
    • Machine sounds normal but no coffee exits

    Limescale Restricting Water Flow

    • Scale blocks thermoblock or boiler
    • Flow meter cannot detect movement
    • Often causes intermittent dispensing

    Failed or Weak Pump

    • Loud buzzing noise
    • No water movement
    • Machine may time out

    Grinder Jam or No Beans Detected

    • Beans not feeding
    • Grinder spinning but not grinding
    • “Fill beans” message may appear

    Solenoid Valve Fault

    • Water not directed correctly
    • Internal blockage
    • Can cause water to divert to drip tray

    Airlock in System

    • Common after descaling
    • Occurs when water tank runs empty
    • Pump runs but nothing flows
