How to Identify the Correct Dolphin Spare Part

Dolphin spare parts can look very similar across cleaner ranges and production generations, but small differences in dimensions, mounting points, seals, connectors and materials can determine whether a part fits and works correctly.

The safest way to identify the correct part is to combine several pieces of information: the exact cleaner model, serial number, any existing part number, clear photographs, measurements, mounting details and the symptom that led to the part being inspected.

This guide explains how to identify common Dolphin pool cleaner parts before ordering and when a repair diagnosis is more appropriate than replacing a visible component.

Before You Order a Dolphin Spare Part

Do not rely on colour, body shape or a single photograph. Confirm the part from several matching details and avoid ordering an electrical or internal component before the fault has been diagnosed.

• Record the exact model and serial number.
• Photograph the complete cleaner and the part location.
• Include any visible part number.
• Measure the component where size helps distinguish alternatives.
• Describe the symptom that led to the inspection.
• Ask for compatibility confirmation where the match is uncertain.

Dolphin Spare-Part Identification Checklist

Step 1: Record the Exact Dolphin Model

“Dolphin pool cleaner” is not specific enough to identify a part. Record the full model name exactly as shown on the cleaner, power supply, manual or purchase documentation.

• Include letters and numbers in the model name.
• Do not rely only on the colour or body shape.
• Check whether the cleaner belongs to the S Series, M Series, Liberty range or Wave commercial range.
• Be aware that the same family name can include different generations.

For example, filters, brushes and tracks from one S Series cleaner may not fit another S Series model even if the body design appears similar.

Step 2: Find and Photograph the Serial Number

The serial number can help distinguish production versions that use different components.

• Look for a label on the cleaner body, power supply or product documentation.
• Photograph the entire label in clear focus.
• Include surrounding details so the label location is visible.
• Do not remove a label that is still attached.
• Avoid relying on a handwritten transcription when a photograph is possible.

If the label is worn, take several photos under different lighting conditions.

Step 3: Look for an Existing Part Number

Some parts, packaging and service documents include a manufacturer part number. Record it exactly.

• Check both sides of the part.
• Look inside moulded plastic areas where numbers may be embossed.
• Check connectors, labels and original packaging.
• Include prefixes, suffixes, spaces and letters.

A visible number may be a mould or manufacturing code rather than the orderable part number, so it should still be checked against the model and photographs.

Step 4: Take Useful Photographs

Photographs are most useful when they show both the individual component and how it fits into the cleaner.

• Photograph the complete cleaner from above.
• Photograph the underside and drive system.
• Take a close-up of the damaged or worn part.
• Show the mounting area after the part is removed where safe and practical.
• Include connectors, clips, screws and cable ends.
• Place a ruler beside the part when size may help.
• Photograph any printed or embossed numbers.

A single close-up without context can make identification more difficult. Include at least one wider photograph showing where the part belongs.

Step 5: Describe the Fault or Reason for Replacement

The visible part may not always be the cause of the problem. Describe what the cleaner is doing.

• Does it move slowly or turn in circles?
• Does it leave debris behind?
• Will it not climb the walls?
• Does it start and then stop?
• Is there clicking, grinding or vibration?
• Is the issue limited to a broken clip, torn filter or worn track?

How to Identify Dolphin Filter Parts

Dolphin filtration components include baskets, filter panels, cartridges, bags, frames, lids and seals. They vary by model and generation.

• Photograph the complete filter assembly.
• Show the shape of the frame and locking points.
• Measure overall length and width.
• Record whether the cleaner uses a basket, panels, cartridges or a bag.
• Check whether the part is coarse, fine, ultra-fine or multi-layer filtration.

A filter that fits physically may still be incorrect if the seals, mesh grade or frame design differ.

How to Identify Dolphin Brushes

Brushes vary by material, width, diameter, mounting points and cleaner model.

• Photograph the complete brush and its mounting ends.
• Record the brush width and diameter.
• Show whether it is a combined brush, active brush or side brush.
• Note the material and visible pattern.
• Compare both sides of the cleaner where more than one brush is fitted.

Do not order by colour alone. Different brush materials can have similar colours while serving different models or surfaces.

How to Identify Dolphin Tracks

Tracks are model-specific and differ in length, width, tooth pattern and material.

• Photograph the full track laid flat.
• Show the inner engagement pattern.
• Measure width and approximate circumference where practical.
• Photograph the drive pulley and roller arrangement.
• Record whether one or both tracks are worn.

A stretched track can look similar to the correct replacement but may no longer provide a reliable size reference. The model and serial number remain important.

How to Identify Rollers, Wheels and Drive Components

Rollers and wheels may vary in diameter, axle design, bushings and mounting method.

• Photograph the part installed and removed where practical.
• Show the axle or retaining clip.
• Measure diameter and width.
• Record whether the part spins freely or is seized.
• Describe whether the cleaner is moving unevenly.

Internal drive gears and motor components should not be replaced solely from a visual guess. A diagnosis may be required.

How to Identify an Impeller or Impeller Cover

Impellers and covers differ by motor unit and cleaner design.

• Photograph the cover from above and underneath.
• Show the screw or clip positions.
• Record any printed number.
• Do not force the impeller if it is jammed.
• Describe whether the cleaner has weak water flow or unusual noise.

If the impeller remains restricted after visible debris is removed, the motor unit may require professional assessment.

How to Identify a Floating Cable

Floating cables vary in length, connector type, swivel design and internal compatibility.

• Record the exact cleaner model and serial number.
• Photograph both cable connectors.
• Photograph any swivel section.
• Measure the approximate cable length.
• Show the damaged area clearly.
• Record whether the fault is intermittent or complete.

Do not repair a damaged floating cable with tape and return it to the pool. Cable replacement may require internal connection work.

How to Identify the Correct Power Supply

Dolphin power supplies can look similar while differing in voltage, connector, controls, app compatibility and cleaner support.

• Photograph the front, back and all labels.
• Record the cleaner model and serial number.
• Show the cable connector clearly.
• Record any power-supply model or part number.
• Note whether it has a timer, Bluetooth, Wi-Fi or app control.
• Describe the fault, including lights and button behaviour.

Never select a power supply only because the connector appears to fit.

How to Identify a Motor Unit

Motor units are internal assemblies and should not be ordered from external appearance alone.

• Use the exact cleaner model and serial number.
• Record the fault symptoms.
• Provide the existing motor-unit part number where available.
• Do not open sealed motor assemblies.
• Arrange professional diagnosis before replacing an internal motor unit.

Symptoms such as no movement, no suction or repeated stopping can have more than one cause.

How to Identify Caddy and Storage Parts

Caddy components include wheels, handles, cable hooks, power-supply holders and frames.

• Photograph the complete caddy.
• Show the broken part and mounting point.
• Record the cleaner model supplied with the caddy.
• Measure wheel diameter or handle dimensions where relevant.

Common Spare-Part Identification Mistakes

• Ordering by colour alone.
• Using only the brand name rather than the exact model.
• Ignoring the serial number.
• Assuming all S Series, M Series or Liberty parts are interchangeable.
• Using a worn or stretched component as the only size reference.
• Sending only one close-up photograph.
• Confusing a moulded manufacturing code with the orderable part number.
• Replacing a visible part before the underlying fault is diagnosed.
• Ordering an electrical component because the connector looks similar.

Avoid Replacing the Wrong Part

A visible worn component may not be the only cause of the symptom. For example, slow movement can involve tracks, rollers, brushes, debris or a drive fault, while poor cleaning can involve filters, seals, water flow or fine debris.

• Replace only confirmed wear items.
• Do not assume an electrical fault is caused by the power supply alone.
• Do not replace a motor unit without diagnosis.
• Record what changed after a part was replaced.
• Arrange professional assessment when the same fault returns.

When a Wear Part Can Be Replaced Directly

Some clearly identified service items can be replaced once compatibility is confirmed.

• Torn or damaged filters.
• Worn brushes.
• Stretched or cracked tracks.
• Broken clips or lids.
• Damaged caddy wheels or hooks.

Use genuine components where available. See Why Genuine Dolphin Spare Parts Matter.

When Professional Diagnosis Is Better

• The cleaner has no power.
• The power supply operates but the cleaner does not move.
• The cleaner repeatedly starts and stops.
• There is grinding, internal noise or vibration.
• The floating cable or connector is damaged.
• There are signs of water ingress.
• The same fault returns after a wear part is replaced.
