FAQ

Those who are looking for an answer to the question «Why is my new electric shower going hot and cold?» often ask the following questions:

👉 Why is my electric shower going hot and cold?

It’s a result of the TCO sensing the water inside your heat exchanger becoming too hot. Ergo, the TCO cuts off the electric supply to all heating elements to prevent you from getting burnt or scalded. Usually, you’ll know this happens because your shower water becomes super hot and then powers off entirely.>.

👉 Why does my electric shower keep going hot and cold?

  • So, why is your shower going hot and cold? The most common reason for this often occurring issue is a blockage in the hot water heat exchanger located inside the boiler. Most probably because of sludge buildup in the heating system.

👉 Why does my electric shower keep going hot then cold?

This is one of the most common culprits of causing water temperature fluctuation. If you’re curious, the logic is that there’s not enough water entering your shower to cool it. So, this causes the safety device to turn off the power to your heat until the shower cools to a safe level (resulting in cold water for you).

There are three common reasons why electric showers go from hot to cold water in an instant. These reasons include a limescale build-up, there might be a problem with the water pressure or the shower might be experiencing electrical faults. Limescale can be removed with a descaling agent. A good cleaning routine will also prevent limescale.

Sometimes backpressure can cause a fault of the shower heating then going cold. Just unscrew the head making sure you don't lose the sealing washer, then using an old toothbrush for example, give the head a good clean. Make sure water is freely passing through the head, then put it back on.

A common complaint with electric showers is that the appliance has a tendency to run cold. Three common causes include a reduction in the pressure of water, there is too much limescale build-up due to hard water, and there is something blocking the gauze filter at the water inlet point.

Hi, I also have a Triton shower, which the last unit did a similar thing, ours is a t300si which means the heat pack is in the loft, so we didn't hear the "click" that you do, but the most likely cause for the problem is the heat can is grounding to earth (the same as an oven element packing up), you can go on line to get the replacement parts but expect to pay about £80-90 for a replacement heat can depending on your model.

A typical electric shower microswitch damaged by heat. Number 4: My shower is going hot & cold. If your shower is going hot and cold, it's usually caused by not enough water getting to the shower. So first of all check that the valve coming into your house is fully open and the valve on the line to the shower is fully open.

When the shower goes cold, and hot, and then cold again it’s natural to blame the combi boiler for the problem. However, if the flame is steady while someone else is showering and reports the water going hot and cold you may have a different problem. To explain this in detail we need to delve a little into combi boiler theory first.

your boiler is recommended to be at around 1.2-1.5bar when the system is COLD, when the heating is ON and up to temperature this will rise up to around 2 bar because of the heated water expanding, this is normal operation, rises of more than around 0.5 bar when the heating is on indicates that a service is required.
