Few things compare to the dread of being greeted with a frigid shower.

If you’re having trouble getting hot water from your electric shower and asking yourself "why is my electric shower cold", don’t worry! You can take some simple steps to troubleshoot the issue and restore your hot water flow. 

Get your hot water running smoothly with these easy-to-follow tips.

Causes of a Cold Electric Shower

The most common cause of an electric shower running cold is an electrical supply fault or wiring problem. It’s important to check the wiring in your bathroom and ensure that all connections are secure. You should also inspect the shower unit itself for any signs of damage or wear and tear. If you notice anything suspicious, it’s best to call a qualified electrician for help.

Another possible issue could be a faulty thermostat. Your thermostat regulates the temperature of your hot and cold water, so if it isn't working properly, you won't get the right temperature from your shower. 

ProTip: To test if this is the cause, turn up the thermostat until it clicks off and then back on again – if nothing happens, then it’s likely that the thermostat is to blame.

Finally, if none of these issues seem to be the problem, it could be a simple case of low water pressure. Low water pressure can cause your hot water flow to become weak or non-existent. To check if this is the issue, you should inspect your shower head and make sure there are no blockages or obstructions. 

You might also want to try changing out the shower head for a new one – this could help increase the water pressure and restore your hot water flow.

Tips for Troubleshooting Your Electric Shower

If you're still having trouble getting hot water from your electric shower, here are some tips on how to troubleshoot the issue:

1. Check the Temperature Setting 

The first step in troubleshooting a cold electric shower is to check the temperature setting on the shower unit. Most electric showers have a temperature dial that allows you to adjust how hot or cold you want the water to be. It's possible that someone may have accidentally tampered with the settings, so make sure that it is set correctly before moving on. 

2. Clean or Replace Your Thermostat Sensor 

If the temperature setting appears to be correct, then the next step is to clean or replace your thermostat sensor. This component measures and monitors the temperature of your shower water and sends a signal to the heater when it needs to heat up more water. If this component is dirty or not functioning properly, it could be preventing your shower from producing hot water. Cleaning or replacing this component should solve this issue quickly and easily. 

3. Replace Your Heating Element 

If cleaning or replacing your thermostat sensor doesn't do the trick, then it's time to move on to replacing your heating element. This component heats up cold water as it enters your electric shower, so if it's malfunctioning then you won't be able to get hot water out of your shower head.

Fortunately, replacing a heating element isn't too difficult—it just takes a bit of technical know-how and patience! Just make sure that you turn off all power sources before attempting any repairs and if you are unsure at all then it is safest to contact a professional to do this.  

4. Check for Leaks  

Another common cause of cold electric showers is leaks in either the pipes or fixtures leading up to your shower head. If there are any leaks, they should be repaired immediately as they can cause serious damage if left unchecked. To check for leaks, turn off your main water supply and inspect all of the pipes leading up to your shower head - look for any signs of wear and tear such as cracks or corrosion which could be causing leaks in your system.

Additionally, inspect all of the fittings around joints and elbows where two pipes connect – any loose fittings should also be tightened up. Once you’ve checked everything over, turn on your main water supply again and test out your shower - chances are it should now be functioning correctly.  

5. Call an Experienced Plumber 

If all else fails, then it’s time to call an experienced plumber who will be able to identify and repair any issues with your plumbing system that might be causing your cold electric showers. An experienced plumber will be able to assess the situation quickly and accurately and provide you with an effective solution so that you can have hot water once again!

6. Consider Changing Shower Head

If you've troubleshooted the above options and still face problems it could be due to low water pressure. It is typically recommended by Plumbers to replace a shower head, here are some options to choose from:

Frequently Asked Questions

How often should I maintain my electric shower?

Your electric shower will require regular maintenance in order to keep it running efficiently. You should check all wiring connections periodically and inspect both water filters for any blockages. It is also important to descale your shower head and clean your shower hose regularly to prevent limescale build up that could lead to a blocked shower head or shower hose. Depending on the usage and water quality in your area, it is recommended to perform basic maintenance checks every 6-12 months.

What is better a thermostatic shower or an electric shower?

The choice between a thermostatic shower and an electric shower will depend on your individual needs and preferences.

Thermostatic showers offer greater control over temperature as they have built-in regulators that keep the water at a consistent temperature, even if there are sudden changes in pressure or flow.

On the other hand, electric showers have no regulation, so the temperature can fluctuate with changes in the water supply. Ultimately, it is up to you to decide which type of shower is best for you. Check out our helpful Shower Buying Guide for more information!
