Saeco 421941306721 Cpu Water Level Sensor Assembly V3

Product Description

The SAECO 421941306721 is a CPU and switch water level sensor assembly, version 3, designed for use in SAECO automatic espresso and coffee machines. This component monitors water reservoir levels and communicates that data to the machine control system, enabling proper operation and low-water alerts. Replacement of a failed water level sensor typically restores normal brewing cycles and prevents dry-pump conditions. Installation is performed by qualified appliance technicians or experienced service professionals familiar with SAECO machine disassembly procedures.

This water level sensor assembly is intended for use in SAECO automatic coffee and espresso machines requiring the V3 sensor configuration. It serves as a direct replacement for the original sensor unit in machines where water level detection has failed or become unreliable. The assembly integrates both the sensor switch and CPU interface components in a single unit, simplifying the replacement process compared to servicing individual subcomponents.

Key Features

• Combined CPU interface and switch sensor in a single assembly
• Version 3 design for compatibility with applicable SAECO machine generations
• OEM-style replacement restores accurate water level detection
• Designed to prevent dry-pump operation by signaling low-water conditions to the control board

Compatibility

Designed as an OEM-style replacement water level sensor assembly for applicable SAECO automatic espresso and coffee machines. Consult the machine service documentation or SAECO parts lookup to confirm fitment before installation.

Installation Notes

Installation should be performed by a qualified appliance technician with experience servicing automatic espresso machines. Always unplug the machine from its power source and allow all internal components to cool and depressurize before beginning disassembly. Handle the sensor assembly carefully to avoid damage to connector pins or the sensor housing. Refer to the machine service manual for disassembly sequence and connector routing specific to the model being serviced.
