How to repair a faulty pool robot

Your pool cleaner won't start? There are a number of things that can affect its operation. The first step is to check that the information sent by the control box reaches the robot correctly. A few simple steps can help you restart your robot without needing to call in a repair technician.

1. Check the control box: unplug the power cable from the socket, wait 10 seconds, then plug the power cable back in.
   

2. Inspect the robot’s cable: Unroll the entire length of the cable along the length of the pool, in the sun, so that it returns to its original shape. Knots can cause damage. Look carefully at both ends of the cable. If you notice any cuts or damage, it may need to be replaced.

3. Clean the robot's propeller: Hair or other debris can build up around the propeller and block it. Disconnect your robot from the electrical supply and wear gloves before handling it. You can find the procedure for your robot in the manual available online here. 

4. Check the state of the tracks on your robot: if a track is loose or if any notches are missing, replace both tracks to maintain the robot's balance.

It is normal that, during a complete cycle ( floor, walls, water line), the robot does not systematically climb the walls to concentrate on the debris at the bottom of the pool. To identify abnormal behavior, observe your robot during the first 20 minutes of its cycle. If you notice that it never climbs the walls or seems to be having difficulty, here are a few things to check:

1. Check the water balance: even crystal-clear water can contain micro-algae that make the walls slippery. Make sure the pH of the water is between 7.0 and 7.6 and that the level of disinfectant is sufficient.

2. Check the state of the filter: a filter that is clogged or full of debris can prevent the robot from climbing up the sides, especially if it has no by-pass. Empty and rinse the filter with clean water. If necessary, clean it with white vinegar.

3. Inspect the condition of the tracks: Worn tracks can also affect the robot's ability to climb walls. Replace them if necessary.

To optimize your robot's movements, place it halfway along the length of the pool at the start of the cycle, which generally gives a minimum of 95% pool coverage. 

Depending on the model of robot you have, it may not be able to climb certain steps on the staircase, even in floor/wall/waterline mode, due to its size in relation to the depth of the steps. If any debris remains after the cleaning cycle in this area of the pool, we recommend that you use a brush to push it towards the bottom of the pool, making it easier for the robot to vacuum it up.

It's also important to know that to work properly, the robots need a water depth of at least 30 to 40 cm, depending on the model. This means that shallow areas of your pool may not be cleaned by the robot. If other areas remain dirty after the cleaning cycle, check the following:

1. Check the state of the filter: If it is full or clogged, clean it with clear water or white vinegar. Make sure there are no holes through which debris can escape.
2. Test different immersion locations: If the robot's cleaning pattern is not optimal for your pool, change the immersion starting point and start a new cycle. After several tries, you'll be able to determine the ideal location for your pool.

If, despite these checks, the robot's behavior does not improve, it is recommended that you call in a professional for more advanced checks and possible repairs.

Over time, some parts of your pool cleaner may wear out, but you can easily replace them by yourself. This is the case with the front brushes (and rear brushes for some models). To check their condition, look at the wear indicator. We recommend changing your robot's tracks every two years to preserve their integrity and ensure optimum cleaning performance.

It is essential to check the condition of the filters regularly. If they are too worn or show tears, replace them. It is generally recommended to change the filter every two years. Your retailer will be able to advise you on the right filter for your robot.

Pay particular attention to the motor propeller. A jammed propeller can cause malfunctions and strain the motor, reducing the life of your robot.

For all other maintenance operations, we recommend that you call in a professional who specializes in repairing swimming pool cleaners.

Although some repairs can be carried out by yourself, others require in-depth knowledge of the electric robot and how to handle it. If your robot does not start after following the recommended actions above, you will need to contact a professional robot repairer.

When it becomes necessary to call in a professional to repair your pool cleaner, it is important to follow certain steps to guarantee a quality service:

1. Contact your retailer: If your robot is still under guarantee, your first reflex should be to contact the retailer from whom you purchased your appliance. They will be able to provide you with the information you need to arrange warranty repairs. You can also find a list of Zodiac dealers near you directly on our website, under the tab Where to buy.

2. Consult your trusted swimming pool specialist:  Outside of the warranty period, it's always a good idea to turn to your trusted retailer or swimming pool specialist. These professionals generally have a network of specialist technicians and can carry out repairs or refer you to an approved, competent repairer.

3. Read reviews and check references for robot repair centers: Before entrusting your robot to a repairer, take the time to read online reviews and check references. Testimonials from other customers can give you a good indication of the quality of service and professionalism of the repairer.

4. Ask for a detailed quotation: Before any work is carried out, ask for a detailed quotation that includes the cost of the diagnosis, even if you decide not to carry out the repairs, as well as the cost of parts and labor. This will enable you to compare prices and avoid unpleasant surprises.

To prolong the life of your electric robot, it is essential to regularly check wear parts such as filters and brushes, as well as the motor propeller. A clogged propeller can force the motor, reducing the life of your robot.

In addition, pay attention to the condition of your pool water before using your robot. For example, avoid running your robot during a shock treatment, as this could damage the body of your robot and lead to premature wear of certain components.

Finally, check the pH of your water once a week. This not only improves your bathing comfort, but also ensures that your robot operates at optimum efficiency.

By regularly tending to your pool cleaner and carrying out a few simple repairs yourself, you can extend its life and keep it running smoothly. For more complex issues, don't hesitate to contact an approved repairer, starting with your trusted retailer or pool specialist. By carrying out regular checks on wearing parts and the balance of your pool water, you can prevent future breakdowns and maintain your robot's optimum performance.
