It's not working properly
It still works a bit, but not the way it should. Safe for a landlord, a shop or IT.
Examples
Since the update, my laptop's not working properly.
The shower's not working properly. The water never gets hot.
In a conversation
A: IT helpdesk, how can I help?
B: Hi, my laptop's not working properly since this morning's update.
Common mistake
Not: My phone is error.
Say: My phone's not working properly.
"Error" is a noun, not a description. Say it isn't working, or "It's showing an error" if there's a message on the screen.
