Many users tend to complain about having this issue where Mira advanced ATL thermostatic shower keeps cutting out.

If you are going through the same problem, I am here to help you with the solutions. Here, I will go through why this happens and how to fix the problem completely. Let’s get started.

Why Is Your Mira Advance ATL Shower Keeps Cutting Out?

There are several reasons for your shower to keep cutting out while you are trying to use them. Some of the reasons can be only limited to your case. 

However, here, I will be going through the common reasons for the problem and giving you solutions according to that. Let’s check out the causes of the problems –

  • Low Water Pressure

Now, the most common cause for having your shower cut off in the middle of usage is the low water pressure from your water supply. 

Because of that, your shower doesn’t get the required water supply; this results in the shower cutting out while you are using it already.

This can happen from the particular plumbing line that goes to the shower. Or the lack of pressure can be for your whole house. 

So, you should check up on that situation first; then you should go for the solution.

  • Limescale Buildup 

This is specific to those who live in a hard water area. Limescale buildup is a common issue that people are living around hard water face all the time with any kind of plumbing.

When you have water residing in your shower for a long duration, it is much more vulnerable to get limescale buildup. If this happens regularly, then you may start noticing that your shower is cutting off quite a lot. 

And the clog from the limescale buildup in your plumbing or shower components is responsible for that.

  • Problems With The Power Supply

Another possible cause of making your shower cut out is problems with the power supply.

Whenever you have issues with the power supply, it can impact the shower’s performance. 

One of the major issues is any kind of thermal cutout trigger.

Usually, this kind of thermal cutout can cause by faulty or damaged wiring. It can also cause by a power surge in the power housing system for your shower. 

Either way, this will result in a lack of power in the shower, making the shower cut out while in use.

Typically, these are the reasons that cause the problem of shower cutting out while in usage. You can try out yourself and some solutions you may need to rely on professionals. 

Let’s check out the different solutions to try out for the problem.

Solving The Problem Of Shower Cutting Out

Now, before you go ahead with the solutions, make sure to determine the proper cause first. If you can’t find out the cause, then I recommend calling a professional right away. 

Don’t try to opt for whatever solution just after coming across the problem.

Having said that, let’s look at some of the fixes that you can try out for this problem with your Mira Advanced shower system.

  • Fixing The Water Pressure Problem

Like I discussed above, first, find out whether you are having an issue all over your house or just the shower system.

If it’s just the shower system, then you will need to opt for a shower pump installation.

Installing a shower pump will give you excellent results with the proper water pressure required to run your electric shower.

There are plenty of options that you can find out there. 

You can choose anyone based on the user experiences and reviews. Or you can simply leave all that stuff to the professionals.

Since this is a pretty technical process, I recommend opting for a professional plumber for the installation. If you have prior experience with plumbing, you can install it yourself. 

Other than that, don’t try to do it if you don’t know what you are doing.

  • Fixing The Limescale Buildup Problem 

There are typically two solutions that you can use for this cause of the problem. You can either use products and chemicals to clean up the lime scale buildup or get rid of the clog. 

Or you can use a permanent solution like using a water softener for your shower system source.

With the chemical solution, you just need to use the descaling agent and clean up the showerhead properly with it. While this fixes the problem for a certain time, you may come across this problem once again after a while.

So, I recommend trying out the water softener to fix this issue for a permanent solution. You won’t have to worry about limescale buildup once you get this solution.

  • Fixing The Power Supply Issues 

If you are dealing with a power supply issue due to a power surge, then just flipping the switch should fix the problem. Sometimes, you may even need to replace the fuse as well.

But if you are dealing with power issues due to faulty wiring, then you simply have to replace or repair the wiring. If you have enough electrical wiring work expertise, you can do it yourself. 

Otherwise, you will need to get a professional to take a look at the wiring and fix it for you.

So, these are the solutions that you can try out for the problem. They aren’t too complicated at all.

Lastly, I think this troubleshooting guide will help you a lot!
