Remove the showerhead and run cold water at max pressure for 10 minutes
Removing the showerhead and running cold water at maximum pressure for 10 minutes is a good way to flush out limescale from your electric shower. This method can help clear limescale blocking the showerhead or filter, and it may also help to descale the heating element.
Before you begin, ensure you have removed the showerhead and any filters at the shower exit. Then, turn on the shower and set it to the coldest temperature. It is important to run the water at maximum pressure, as this will help to dislodge and flush out any limescale build-up.
Let the shower run at full pressure and cold temperature for 10 minutes. This will help to remove any loose limescale and prevent future blockages. If you have particularly stubborn limescale, you may need to repeat this process several times.
After 10 minutes, turn off the shower and inspect the heating element and showerhead to see if any limescale remains. If there is still limescale present, you may need to try a different method, such as using a limescale remover or a mixture of bicarbonate of soda and vinegar. You can also try running very hot water through the shower for a minute, followed by very cold water, repeating this process several times to crack and remove limescale.

Remove any filters, then alternate between full hot and cold water
If you live in a hard water area, limescale can be a nuisance. It can leave a chalky white residue inside your appliances and its build-up can lead to reduced water flow in your pipes and taps. Limescale build-up can also affect the performance of your shower by clogging up the head and building up inside the unit, impacting water flow and pressure.
To descale the inside of an electric shower, you can try removing any filters and then alternating between full hot and cold water. Here's a step-by-step guide:
- Remove the showerhead: Take off the showerhead by unscrewing it or following the manufacturer's instructions.
- Remove any filters: Look for any filters at the exit of the shower, such as the showerhead filter, and remove them.
- Alternate between full hot and cold water: Set the shower to full hot water and let it run for about a minute. Then switch to full cold water for another minute. Repeat this process of alternating between hot and cold water for 4-5 cycles.
- Flush with cold water: After alternating temperatures, run the shower on full cold water for about 10 minutes to help flush out any loose limescale.
By varying the water temperature and removing any filters, you can crack and flush out the limescale buildup inside the heating element and shower unit. This method is particularly useful if you are unable to descale the heating element using a descaler or limescale remover.
Additionally, you can also try using citric acid or vinegar to clean the showerhead and remove calcium deposits. Soaking the showerhead in these solutions and then running the shower on hot water can help remove limescale and improve water flow.

Use a limescale remover
Limescale is a common problem for electric showers, especially in hard water areas. It can cause poor temperature control, reduced energy efficiency, and even heating element failure. To remove limescale, you can use a limescale remover solution, which can be purchased from any convenience store. Here is a step-by-step guide on how to use a limescale remover to descale your electric shower:
First, ensure the showerhead is dry. Then, apply the limescale remover solution to the showerhead, making sure to avoid getting it on your clothes or skin, as these solutions contain harsh acids. Leave the solution on for about 10 minutes, then use an abrasive sponge to scrub away the limescale. You can also use a toothbrush to scrub the exterior of the showerhead and the area around the nozzles to remove any remaining limescale deposits.
If there is substantial limescale buildup, you may need to leave the solution on for longer or repeat the process multiple times. Before using any limescale remover, always read the instructions on the product label and take the necessary precautions, such as wearing protective gloves and ensuring proper ventilation during use.
In addition to using a limescale remover, you can also take preventive measures to reduce limescale buildup in your electric shower. This includes regularly descaling your showerhead, purchasing a showerhead with anti-scale nozzles, or installing a water softener to remove minerals from your water supply. By combining regular descaling with preventive measures, you can effectively manage limescale buildup and maintain the performance of your electric shower.

Try citric acid or vinegar
Descaling your electric shower regularly is important to prevent limescale buildup, which can reduce the efficiency of your shower and cause damage. Limescale is a mineral deposit that forms when hard water evaporates, and it can block your shower's pipes or reduce the flow rate of hot water.
To descale your electric shower using vinegar, start by turning off the power supply to your shower at the mains switch for safety. Then, mix equal parts white vinegar with warm water in a spray bottle. Spray the solution directly onto any affected areas, including buttons and controls, and wipe them off with a damp cloth or sponge. You can also try filling a bucket with one part vinegar and three parts water, dipping a cloth into the solution, and wiping down all surfaces of the shower unit. Alternatively, place your shower head in a freezer bag and fill the bag with undiluted vinegar or a mixture of five parts water and one part vinegar. Leave the shower head to soak for 30 minutes to two hours, then remove it from the vinegar and rinse it thoroughly.
Citric acid is another effective option for descaling your electric shower. It is a natural cleaner that can remove soap scum, hard water stains, lime, and rust. Before using citric acid, perform a spot test on an inconspicuous area to ensure it does not damage the material. Always follow the dosage and safety instructions on the packaging, and protect your hands with gloves to prevent skin irritation. To use citric acid to descale your shower, dissolve a level teaspoon of citric acid in a bowl of cold water and swirl your shower head in the solution for 15 to 45 minutes. You can also try mixing one part citric acid with one part vinegar in a spray bottle and wiping down surfaces with a microfiber cloth. For particularly stubborn limescale, boil six to eight cups of water, pour it into a water tank, and add enough citric acid to cover the affected area. Let the solution sit for five minutes, then scrape away the deposits.

Install a water softener
If you live in a hard water area, you may experience limescale buildup in your electric shower. This can cause a reduction in water flow and even affect the performance of your shower. While there are some home remedies to descale your shower, such as flushing it with cold water or using a limescale remover, a more permanent solution is to install a water softener.
Water softeners work by converting hard, mineral-rich water back into soft water, thus reducing limescale buildup. There are two main types of water softeners: whole-house water softeners and point-of-use shower filters. Whole-house water softeners treat all the incoming water in your home, reducing its overall hardness and preventing limescale in pipes and appliances. These systems often use ion exchange, replacing calcium and magnesium ions with sodium or potassium ions, to soften the water. They range in price from $1500 to $3000, with installation included.
If you are unable or unwilling to install a whole-house system, you can opt for a point-of-use shower filter. These filters are installed at a single showerhead and can significantly reduce chlorine, heavy metals, and some portion of the minerals that contribute to limescale. While they do not remove minerals as effectively as a comprehensive water softener, they are a more affordable option and can still provide benefits to your hair and skin.
When choosing a water softener, it is important to consider your household size and water consumption rate. For example, the Water2Buy EASY W2B200 Water Softener is suitable for up to 6 people and can filter 1250 litres per day. On the other hand, the BWT WS755 can process a larger volume of water (4167 litres per day) but is also a larger unit, standing at 80cm tall.
If you are looking for a water softener that does not require a power source, the Monarch Water Ultra HE is a good option. It is powered by a single V9 lithium battery and uses a twin-tank meter system with increased surface area resin beads, providing greater capacity per regeneration.
By installing a water softener, you can effectively reduce limescale buildup in your electric shower and enjoy the benefits of softer water for your skin, hair, and appliances.
