Well, you’re probably wondering why the immersion heater is not working. The straight answer is that the culprit may be anything from a faulty thermostat to damaged elements, and even limescale buildup.
Secondly, how do I know if my immersion heater is broken?
Also know, how do I know if my water heater element is burnt out?
How do I reset my immersion heater?
Somewhere on your electric water heater, you’ll find a reset button. It’s usually red and often located near the thermostat. It may also be hidden behind a removable metal panel on the unit—and then behind some insulation. Once you find the button, push and release it.
Push down the red segments on the timer face corresponding to the operating time needed. One segment is equal to 15 minutes. Turn the central clock face so that it is the current time, or rotate the outer disk clockwise so that the solid black arrow points to the current time.
We recommend installing an immersion heater timer, which works just like a thermostat. This means that when the water reaches the desired temperature, the immersion tank will automatically turn off, so you aren’t wasting money.
An immersion heater may last for between two and three years before it burns out and needs to be changed.
Once you’ve reset the system, you have to wait for hot water (unless you have an on-demand water heater), but for how long? It depends on the size of the tank, but with any unit, you should be able to get in a hot shower with gas water heaters within 30-40 minutes and with electric tanks, about 60-90 minutes.
“The main problem with leaving an immersion on constantly is that the immersion thermostat will be constantly switching on and off. After so many hours the thermostat will give up, causing one of two problems.” “Problem one is that the immersion will not work.
A water heater that produces no hot water may not be getting power, may have a tripped limit switch, or may have one or more failed heating elements. First, check the water heater’s circuit breaker in the service panel to make sure it hasn’t tripped. If the breaker has tripped, switch it off, then switch it back on.
If your water heater loses power, your water heater’s reset button can be used to turn the appliance back on. However, your reset button serves as a safety device and turns the unit off when the water temperature gets too hot.
