The answer to 'why is my water softener no hot water' is that the water softener may be malfunctioning or not properly connected to the hot water supply. This can prevent hot water from reaching the taps and appliances in your home. Common causes include a clogged or faulty water softener, incorrect installation, or issues with the water heater.
To troubleshoot, first check the water softener to ensure it is powered on and cycling properly. If the softener is working but you still have no hot water, the issue may be with the water heater or the connections between the two systems. You may need to call a professional plumber to inspect the entire setup and make any necessary repairs or adjustments.
