Bosch EasyControl powers on but frequently reboots or restarts by itself, sometimes losing connection to the boiler or Wi‑Fi.

Safety first: Isolate mains power before handling wiring.

• 1. Check mounting: Ensure the EasyControl is mounted on a flat wall with adequate ventilation and not enclosed in a small cabinet.
• 2. Inspect connections: Remove the EasyControl from the wall plate and check that all screw terminals are tight and that no bare wires are touching.
• 3. Stabilize supply: Avoid powering the EasyControl from circuits shared with heavy inductive loads (e.g., large motors) that may cause voltage dips. If necessary, have an electrician move it to a more stable circuit.
• 4. Monitor temperature: Feel the wall around the EasyControl during operation; if it is very warm, consider relocating away from heat sources.

Professional help: Persistent random reboots with good wiring and ventilation indicate an internal hardware fault; the unit should be replaced.
