Possible Causes

Stuck 3-way diverter valve, Limescale in rinse valve, Faulty diverter valve coil, Broken valve actuator

How to Fix / Troubleshooting

Safety first: Unplug the machine before accessing internal valves.

Descale and flush:

  • Run a full descaling cycle to dissolve limescale in the diverter valve and rinse circuit.
  • After descaling, run multiple rinse cycles to flush debris.

Valve inspection (advanced):

  • Remove the cover to locate the 3-way diverter valve that directs water between brew, rinse, and waste paths.
  • Check for kinks or blockages in the connected hoses.
  • With the machine powered (exercise extreme caution), listen for the valve clicking when a rinse or brew cycle starts. No click may indicate a failed coil.

If the valve is mechanically stuck or the coil is open, replace the diverter valve assembly. This repair is best performed by a technician due to the complexity of the hydraulic routing.
