Three-way solenoid dripping

A slow drip from the group head after the shot ends and the pump stops — water continues to weep from the shower screen for 30+ seconds.

Why it matters — Indicates the 3-way solenoid isn't sealing properly after the shot. The drip itself is harmless; it's a sign the valve is gumming and may fail completely if ignored.

Good to know

• A weekly detergent backflush usually clears the problem before it gets worse.
• If a backflush doesn't fix it, the valve seat or seal is worn — replacement parts are inexpensive and the swap is straightforward.
