Why has your hot water stopped after an electrical fault?
Immersion heaters and boilers sit on their own circuits, and both are common casualties when an RCD trips or a fuse blows. The heater element itself can also fail and take the circuit down with it, which is why the trip often returns when you reset it.
What is safe to check yourself?
Look at the fuse board for a breaker that is off, often labelled immersion, water heating or boiler, and reset it once. Then find the switched spur near the cylinder or boiler, a small wall switch usually with a neon light, and make sure it is on.
Gas boilers still need electricity. If the display is dead, the fault is electrical even though the boiler burns gas.
When should you call an electrician?
Call us if the circuit trips again after one reset, if the spur or its faceplate smells hot or is discoloured, or if the board shows nothing wrong but the appliance is still dead. A failed immersion element leaks current and will keep taking the RCD down until it is disconnected.
Do not keep resetting, and do not bypass anything to get the water hot. A cold shower is cheaper than a rewire.
What will we do when we arrive?
We test the circuit, isolate a failed element or repair the wiring fault, and get the rest of the house stable. If a new element or a heating engineer is the fix, you will know before you spend anything more. See our same-day urgent repairs.
