If you’ve suddenly found yourself with no hot water, one of the first places to check is your meter box. Top tips include checking for a faulty relay, which is controlled by your power board. This relay sends power to your hot water cylinder, so if it fails, the water won’t heat.
In the video above, we walk you through what to look for from checking if the hot water circuit breaker is on to inspecting the relay for visible damage or signs of wear. Our top tips also cover how the controlled load system works, and why power companies sometimes manage hot water heating times remotely.
These checks are part of our regular electrical maintenance services across Hamilton and the Waikato. If you’re unsure or uncomfortable working around electrical components, always contact a licensed Hamilton electrician for help. Top tips for safety include never attempting repairs alone.
