Turn off the power

Before attempting to fix an electric shower pull cord, it is important to turn off the power supply to ensure safety and avoid any potential hazards. Here are some detailed instructions and considerations for turning off the power:

Identify the Power Source

Locate the power source for your electric shower. It could be connected directly to the mains supply or have a dedicated circuit breaker or fuse box. If you are unsure, consult an electrician or a professional.

Once you have located the power source, proceed to turn off the power. If it is connected to the mains supply, turn off the mains power at the main breaker box. Ensure that you only turn off the specific circuit breaker supplying power to the shower to maintain electricity supply to other areas of your home.

Check for Damage

After turning off the power, carefully inspect the shower's electrical components for any signs of damage. Look for visible issues such as loose wires, damaged cables, or burnt components. If you notice any damage, do not proceed with the repair and contact a qualified electrician.

Disconnect the Power

If your electric shower has a dedicated power connection, such as a plug connected to an outlet, ensure that it is properly unplugged before proceeding. This step may involve accessing the electrical panel or junction box behind the shower to disconnect the power supply.

Safety First

Always prioritize safety when working with electrical appliances. Ensure that the power is completely turned off before handling any components. Use appropriate safety gear, such as insulated gloves and eye protection, to safeguard against potential electrical hazards.

By following these steps, you can confidently turn off the power supply to your electric shower, ensuring a safe environment for troubleshooting and repairing the pull cord mechanism. Remember to exercise caution and seek professional assistance if you are uncomfortable or unfamiliar with electrical work.

Check for damage

Before attempting any repairs, it is important to check for damage to the electric shower pull cord and its components. Turn off the power to the shower at the mains to ensure safety.

Begin by examining the pull cord itself. Look for any signs of physical damage, such as fraying, exposed wires, or burn marks. A damaged cord will need to be replaced. If the cord appears intact, locate the plastic 'acorn' near the top of the cord and unscrew it. This will reveal the internal mechanism, allowing you to inspect for any damage or obstruction.

Next, inspect the switch or pull cord enclosure. Check for any visible damage, such as cracks, discolouration, or melting. These issues may indicate heat damage, which is a common problem with shower switches due to the high electrical resistance generated during use. Small cracks on the front of the switch, often mistaken for signs of impact damage, can indicate extreme heat and cable damage behind the switch.

Additionally, check the wiring inside the enclosure. Ensure that the wires are not damaged and are securely connected. Loose terminal connections can cause the pull cord mechanism to fail. Also, look for signs of corrosion, especially if the shower is older, as this can increase electrical resistance and lead to heat-related issues.

If you notice any damage or are unsure about any aspects of the repair, it is recommended to consult a qualified electrician. Electric showers draw a significant amount of current, so it is crucial to prioritise safety and ensure that any repairs are performed correctly.

Loosen screws

Before attempting any repairs, it is important to ensure your safety by turning off the power. Electric showers typically draw around 40 to 50 amps of electricity, so it is crucial to cut off the electricity supply to the shower before working on it.

Now, let's focus on the "Loosen Screws" aspect of fixing an electric shower pull cord. Here are some detailed instructions:

  • Identify the screws that need to be loosened. These could be the retaining screws holding the switch in place or the screws that secure the wires.
  • If you are dealing with a 45-amp shower switch, locate the two retaining screws. You may need to set up a ladder to reach the switch safely.
  • Before loosening the screws, ensure you have turned off the circuit you are working on. This can be done by turning off the MCB (Miniature Circuit Breaker) or pulling out the fuse in the consumer unit or fuse box.
  • Once the power is off, carefully loosen the retaining screws. You may need to use a screwdriver designed for electrical work, which has insulated handles and is marked for safe use around electricity.
  • After loosening the screws, gently pull the switch down a little to access the wires. Be cautious not to pull too forcefully, as this may damage the wiring.
  • Inspect the wiring to ensure there is no visible damage. If the wires appear intact, slightly loosening the screws may have solved the issue.
  • If the problem persists, you may need to loosen the spring mechanism inside the switch to make it work properly. First, try using a maintenance spray or WD-40 to lubricate the area.
  • If loosening the screws and the spring does not resolve the issue, you may need to consider a permanent fix or consult an electrician.

Remember, always prioritize your safety when working with electrical appliances. If you are unsure about any aspect of the repair, it is best to seek professional assistance to avoid any potential hazards.

Replace the cord

If your electric shower pull cord is faulty and needs to be replaced, you can do so by following these steps:

Firstly, it is important to turn off the power to the shower before attempting any repairs. This is a crucial safety measure. Check that there is no visible damage to the cables.

Next, locate the plastic acorn-shaped cover at the top of the cord. This should be about 5-10cm from the top of the cord. Use a ladder to reach it if necessary. Once located, unscrew the plastic acorn to reveal the inner mechanism.

At this point, you can remove the old cord by untying the knot that holds it in place. Take care to note how the cord is threaded so that you can replicate this when installing the new cord.

Now, take your new replacement cord and thread it through the same way as the old one was. Knot the new cord securely and trim any excess cord as needed.

Finally, screw the plastic acorn cover back into place, and restore power to the shower. Test the pull cord to ensure it is now functioning correctly.

Replacement shower cords can be purchased from most DIY stores, and it is a straightforward process to fit them. However, if you are uncomfortable with any aspect of the repair, it is recommended to consult a qualified electrician.

Call an electrician

If you are unsure about how to fix an electric shower pull cord, it is best to call an electrician. Electric showers can be 9 to 10 kW, and a lot of current is drawn by them. This means that any repair work must be done with care and attention to avoid electrical faults.

If the pull cord is not working, it could be due to a fault in the chord itself, or the power supply to the switch. A qualified electrician will be able to run a power test to determine the cause of the issue. They will also be able to replace the pull cord or switch if necessary, ensuring that the new part is correctly rated for the load it is supplying.

In some cases, the pull cord mechanism may fail due to loose terminal connections or wear and tear. Again, an electrician will be able to identify this and carry out the necessary repairs or replacements. It is important to note that shower pull cords are designed for occasional use, and continual use can cause them to wear out quickly.

If there is any indication of heat damage, melting, or cable damage, an electrician should be called to investigate and resolve the issue. This may involve replacing the shower isolator or the entire switch.

While some people may attempt to replace the pull cord themselves, it is important to have the necessary knowledge and understanding of electrical installations. If in doubt, calling an electrician is the safest option to ensure that the repair is done correctly and safely.
