Aqualisa Shower Problems? Here’s Why
Aqualisa showers are awesome – right up until they’re not. If you’re having Aqualisa shower problems, though, you’ve come to the right place. We’ve dealt with this a few times at DreamyHome, and that means we’ve got the clearest solutions possible to get your shower up and running again. While it may seem like a big task, the solution is actually pretty simple – it just takes time. So buckle in and keep reading to get this all sorted.
The most common cause for many Aqualisa shower problems is an air lock.
Let’s talk about how to resolve that now, shall we?
What is an Air Lock?
Believe it or not, your plumbing system actually has air inside of it. While this is entirely normal (air is literally everywhere, after all), it can pose a bit of a problem when it meets a sharp curve in the plumbing.
This, in turn, causes what’s called an air lock. In short, what this means is that air has locked your plumbing from functioning properly. This happens because your plumbing comes to specific high and low points. As air is less dense than liquid, it rises to the high points in your plumbing, creating an air bubble. This air bubble prevents water from going where it’s supposed to, and can make it impossible for a tap or shower to get water.
Luckily, the fix is pretty simple.
How to Fix an Air Lock
First things first – start by locating your shower’s control unit and resetting it. Switch the power off, then go back to your shower. Remove the showerhead from the hose and let the hose go to the ground. Turn your control unit back on in ~30 seconds.
This reduces the pressure needed to get the water flowing, and if it’s on your shower floor, will prevent a mess. Now:
- Turn the shower onto its coldest setting. Let it run – you may see water come out, you may not.
- Try again until some water comes out.
- Keep doing this in 3-5 second spurts, letting the water run a bit longer each time. You should hear less “sputtering” as you do this.
- Once you have a steady flow of water (even if it’s miniscule) it’s time for the hot.
- Run hot water and repeat the process until the issue resolves.
- Alternatively, you can start hot then go cold. It doesn’t really matter which goes first, just that it’s extremes of each.
Another potential fix would be to locate your control box and turn off the cold water supply entering the box. Unscrew the cold inlet and remove the gauze filter, cleaning any gross buildup. Reattach the cold supply and test your water.
An Alternative Approach (Or Three)
There are a few other ways to fix an air lock, so if the first one doesn’t work, move onto these ones. If you call a plumber, they’ll do one (or more) of these techniques, so you’ll be saving them time, worst case.
The simplest way to resolve an air lock is to simply open all of the taps in your home. Turn them all on full blast (watching to ensure there’s not an overflow situation, that would be bad). This includes your shower head – I recommend removing the shower head as in the first option to allow better water flow.
The next option is to bleed your radiators (if you have them).
The final possible solution involves your washing machine. Here’s what to do:
- Turn off the hot and cold water valves to your washing machine. Disconnect the hoses (located at the back).
- Connect a hosepipe to the valves, turning on the hot water valve once done.
- Turn on the cold water valve, and let them both go for 30 seconds.
- Once the air lock is resolved, close the cold then hot valves, reattaching the pipes.
While the most likely cause of a wide number of Aqualisa shower problems can be traced back to an air lock, there are a few other things to keep in mind. These include:
- A faulty coil – This often causes hot water to cut out, or water to stop completely. If this is the case, you’ll need a professional to find and install a replacement coil.
- Bad processor or microchip – Aqualisa showers are electric showers. This means that they have a few complicated bits of electronics inside. If a chip or processor fails, you’ll need to replace the shower itself. The cost of replacement parts and replacement labour is often more than a new shower.
- Faulty stabiliser or flow valve – This will cause hot water to cut out consistently. To fix this, you need to check the main (house and shower) valves are fully open. If they are, you need a professional.
If your Aqualisa shower has developed problems. the most likely cause (if you have no water at all, or a small drip) is an air lock. While this is a common and easily resolved issue, there are a few methods to handle it. The first is by using the valves on your shower to go either hot to cold, or vice versa, opening your water lines to the full capacity and letting your water run. Alternatively, bleeding your radiators, using the washing machine method, or simply opening all of your home’s taps can also resolve this.
While an air lock is the most likely culprit, there are a few other potential causes to shower issues. If your hot water cuts out regularly (or all water cuts out), it could be one of two things. The first is a faulty coil, while the latter is a bad stabiliser or flow valve. Both need to be replaced by a professional. Additionally, you could have bumped your water valves, or have a failed processor. The former can be resolved by just… opening the valves, while the latter needs a full replacement.
Hopefully, this resolved your Aqualisa shower problems quickly and efficiently – now for the toasty shower you deserve.
