The typical lifespan of a Samsung EHS compressor is between 10-15 years, provided it's regularly serviced and operated within the manufacturer's specifications.
Ensure proper drainage around the unit, optimise defrost cycle settings, and consider installing a base heater to prevent ice accumulation.
F-Gas regulations prohibit unqualified individuals from handling refrigerants. Any work on the refrigerant circuit must be performed by a certified F-Gas engineer to prevent environmental damage and legal penalties.
The Samsung EHS heat pump is emitting a distinct clicking sound every 10 seconds. This occurs predominantly during heat demand cycles. No visible error codes displayed on the unit's controller. Sound appears to originate from the outdoor unit, potentially near the compressor. No app-side telemetry drops or connectivity issues detected.
Access the Samsung EHS diagnostic mode (refer to the service manual for the button sequence) to view real-time system parameters, error history, and component status. This can provide valuable insights into the cause of the clicking sound.
The Samsung EHS ASHP uses a vapor-compression refrigeration cycle with R32 refrigerant. Flow rate is controlled by a modulating circulation pump. Weather compensation logic adjusts flow temperature based on external temperature sensors. The clicking sound may indicate a mechanical issue within the compressor, reversing valve or associated components. Defrost cycles are triggered based on coil temperature and humidity levels, especially prevalent during UK winter conditions.
Working with heat pump systems involves potential electrical hazards (230V/400V AC). Ensure the system is isolated before any electrical work. Refrigerant handling requires F-Gas certification; do not attempt DIY repairs on the refrigerant circuit. Improper handling can result in environmental damage and legal penalties. Be aware of G3 unvented hot water safety (Tundish) regulations.
