Rancilio water switch s 10705366

What is the on/off switch

The switch is used to start and stop the power supply of the coffee machine. Pressing it closes or opens the electrical circuit that supplies current to the heater, pump and control electronics. Without a functional switch, the appliance will not turn on at all or cannot be safely switched off.

When the part stops doing its job

• The coffee machine does not turn on even after pressing the button
• Switching on only works in a certain position or with firmer pressure
• The appliance switches itself off or the indicator lights flash without responding to controls
• The switch feels loose, stuck, or lacks the mechanical resistance it used to have

Why replace this part in time

A damaged switch can cause intermittent power supply, which strains the electronics and increases the risk of a complete failure of the coffee machine. Timely replacement prevents bigger faults and ensures reliable and safe operation of the appliance.

How to choose the right part
