Why is My Electric Shower Going Hot and Cold?

Electric Shower Going Hot and Cold? Resolved!

Oh, the joy of a hot shower turning suddenly cold! If you’ve ever experienced this, you know it’s anything but pleasant.

When electrical showers run hot and then cold, it is usually caused by: limescale, water pressure, or electrical faults.

But don’t worry, I’m here to help you understand why this happens and how to fix it.

So grab a towel, and let’s dive in!

Why Is My Electric Shower Going Hot Then Cold?

1. Limescale Build-Up

You know that annoying white stuff that forms on your shower head? That’s limescale, and it’s a common culprit behind the hot-to-cold shower problem.

How to Fix It?

  • Spotting Limescale: Look for grey or green deposits. If you find them, you’ve got a limescale problem.
  • Descaling: Use a descaling cleaner to get rid of it. Regular descaling can prevent this issue altogether.
  • Prevention: Consider installing a magnetic softener in the inlet pipe or adding a water softener to your home’s main water supply.

2. Water Pressure Problems

If your shower’s acting like a moody teenager, switching between hot and cold, it might be a water pressure issue.

How to Fix It?

  • Check the Pressure: You’ll need about 1.5 bar static and 1.0 bar running pressure. A hand-held pressure device can help you test it.
  • Listen for Clicking Noises: If you hear clicking inside the unit, low water pressure might be the cause.
  • Clean or Replace the Mesh and Valve: Sometimes, clogged mesh or a malfunctioning valve can mess with the pressure. Cleaning or replacing these parts can solve the problem.

3. Electrical Faults

This one’s a bit tricky. Electrical faults can cause your shower to go from hot to cold (or even not work altogether), and it’s not something you should mess with unless you’re an electrician.

How to Fix It?

  • Call an Electrician: If you’re not sure what’s wrong, it’s best to call a professional. Electrical work can be dangerous, and it’s not worth risking your safety.
