Pool robot repair: 3 common solutions

• Pool robot does not start or turn on
• Pool robot stops
• Pool robot stops after a few seconds
• Pool robot stops after a few minutes
• Pool robot does not complete the cleaning cycle

These are the most common problems when it comes to pool robot repair. Today we will discover together the best solutions to solve every issue.

This guide is valid for any robot: Dolphin, Zodiac, Aquabot, BWT, Hayward.

Repairing a pool robot is a process divided into three fundamental phases:

1. Diagnosis
2. Power supply unit
3. Power cable
4. Traction and pressure
5. Motor unit
6. Repair
7. Pool testing

The power cable supplies the current required from the power supply unit to the pool robot. If it is damaged, it may cause the robot to shut down unexpectedly or prevent it from starting.

To verify proper operation, if a swivel is present, it is first necessary to carefully open it and check that there are no water infiltrations inside.

Then, with the same care, unscrew the connector connected to the motor unit and remove it, in order to inspect the cable entering the motor unit.

Using the same tester set to direct current, turn on the power supply unit with the cable connected and check that the same output voltage from the power supply is present on the white and black pins.

If the voltage matches the expected value, it means that both the cable and the power supply unit are functioning correctly. Otherwise, the robot’s problem lies in this stage.

Traction refers to the gears, bearings, pulleys, and brushes, meaning all the components that allow the robot to move inside the pool. At this stage, it is necessary to manually check that everything rotates freely.

Next, the side covers must be opened to verify that every component is in good condition and does not require replacement.

Regarding pressure, the most common issue concerns the propeller, impeller, or filter. Check that the impeller does not contain debris, threads, or damage. Also verify that the filter is intact, not clogged, and does not need replacement.

Once it has been verified that the correct voltage reaches the motor, thus excluding the power supply unit and cable as possible causes of the malfunction, it is necessary to intervene on the motor unit.

At this point, two solutions are available:

• Replacement of the motor unit, if it is certain that the issue originates from it. In this case, installation must be carried out exclusively by specialized service centers to avoid voiding the manufacturer’s legal warranty.
• Attempting to repair the motor unit by replacing the damaged internal component.
  

The second option is a very delicate operation and is not recommended for those without the necessary experience, as it can easily cause further damage up to complete failure of the unit. The most common causes involve water infiltrations due to improper sealing.

Internal repair is a process that must be performed by experienced technicians equipped with all the necessary tools and spare parts to ensure a safe and permanent restoration of the motor unit.

Once the components responsible for the malfunction, and therefore for the premature shutdown or failure to start, have been identified, the pool robot repair phase begins, meaning the inspection and replacement of all defective parts.

As already mentioned, this step is very delicate: if the parts supplied by the manufacturer are not installed correctly and by specialized personnel, the legal warranty may be voided.

It is essential to thoroughly verify that every element is in optimal condition, because worn or unchecked components could damage the new ones.

For example, if the traction components are compromised, they could place excessive stress on the newly installed motor and damage it, thus voiding its warranty.

For these reasons, it is important to rely on a trusted, serious, and reliable service center with positive and verified reviews. At MetodoBlu.com, we are committed to offering an excellent, affordable, and fast service.

If you would like to entrust us with the repair of your pool robot, you can request a 100% free quote, choosing whether to ship the robot directly to us or use our home pickup courier service.

Pool testing is a fundamental step after replacing the faulty parts and verifying that the other robot components are intact and will not compromise the new ones.

At MetodoBlu.com, we always perform three complete test cycles to ensure that the pool robot operates correctly and without issues.

At the end of the tests, the robot is ready for delivery.

The duration of the entire repair process varies depending on the type and complexity of the malfunction, but in general we are able to provide a quote within 1 or 2 days from receiving the robot, guaranteeing fast and professional service.
