3-Way Solenoid Valve Assembly
The buzzing sound is a mechanical vibration of the internal plunger against the valve seat. This is caused by an incomplete magnetic seal, often resulting from scale accumulation or the degradation of the shading coil within the solenoid. Replacing the assembly restores the integrity of the magnetic circuit and stops the harmonic chatter.

Triac PCB Assembly
In this specific chassis, moisture ingress from the boilers frequently settles on the power board, causing the Triacs to 'leak' a low-level voltage to the solenoid. This insufficient current is enough to create a magnetic field that vibrates the plunger without fully retracting it, leading to a persistent electrical buzz.

Boiler Probe O-Ring Kit
Forensic data shows the root cause of electrical buzzing in the BES920XL is typically the failure of #007 silicone O-rings on the steam and brew boilers. When these seals fail, escaped steam condenses on sensitive electronics, including the solenoid coils and Triac boards, leading to the electrical malfunctions described by the user.
