Hitachi Global Life Solutions, Ltd. (hereinafter, Hitachi GLS) has launched a downloadable updated version of its home support app 'Happiness Up,' which makes Hitachi-branded home appliances more convenient and reliable to use. The update introduces new diagnostic features and changes the name of the existing '[Diagnose Symptoms via Smartphone]' function to 'My Appliance Diagnosis' (*3). This upgrade aims to further enhance after-sales services, ensuring customers can continue using their Hitachi appliances with confidence and peace of mind.
'My Appliance Diagnosis' is a service for customers using Hitachi's connected refrigerator and washing machine models (*4). Based on operational data (*5) from the user's appliance, it enables easy and free diagnosis of potential issues.
As a new feature, certain refrigerator models now analyze past operational data to determine the status as 'Normal,' 'Caution,' or 'Malfunction,' displaying diagnostic results and advice (*6). If necessary, users can directly apply for repair services from the diagnosis result screen (*7). By expanding diagnosable symptoms and incorporating historical data analysis, the service supports identifying root causes of malfunctions, reducing customer anxiety, and enabling smooth responses.
(*1) 'Connected Appliances' is a registered trademark of Hitachi, referring to smart home appliances connected to the internet.
(*2) Use of 'Happiness Up' requires registration with the Hitachi Home Appliance Members Club.
(*3) The feature name has changed from '[Diagnose Symptoms via Smartphone]' to 'My Appliance Diagnosis' (as of June 2026).
(*4) Eligible models include Hitachi connected refrigerators (excluding R-KC11R and R-KX57K) and connected washing machines (excluding BD-NX120C).
(*5) Operational data used for diagnosis does not include recent data (e.g., from the same day), so results may differ from the appliance's current condition.
(*6) 'My Appliance Diagnosis' is available when a connected refrigerator is paired, but diagnosable items vary by model. 'Normal/Caution/Malfunction' judgments are only available on supported models. For unsupported models, advice is provided based on operational data. Diagnosis may not be immediately available if insufficient data exists, such as shortly after pairing.
(*7) If the app displays a 'Home Appliance Emergency Alert' or if physical damage is present, inspection or repair should be considered regardless of diagnosis results.
