- Motor Top Cover, Servo and PCB for Dolphin M600 Motor Top Cover, Servo and PCB for Dolphin M600
- Description
- Reviews
Genuine Dolphin motor top cover, servo and PCB assembly for compatible robotic pool cleaners, including the Dolphin M600 and M700. This replacement assembly combines the servo mechanism and printed circuit board to restore directional drive control.
Compatible Models
Designed to fit the following robotic pool cleaners:
- Dolphin M600 / M700
- Dolphin Active X6
- Dolphin Ultimate
- Aquawize AW6
- Dolphin Wave 90i
Important Installation Note
Replacing individual internal electrical components of a sealed robotic motor block carries technical risks (such as compromising the watertight seal). If you are not comfortable performing this component-level repair, pool service professionals generally recommend replacing the entire sealed motor unit instead.
Main Reasons for Replacement
The symptoms below can have several causes. A technician should diagnose the fault before replacing the assembly.
| Fault | Symptoms | Possible cause |
|---|---|---|
| 1. Water ingress | Robot stops working, intermittent operation or complete failure | Moisture enters the motor block and corrodes the PCB |
| 2. PCB electronic failure | Robot powers up but fails to operate correctly | Damaged electronic components or motor-control circuitry |
| 3. Servo mechanism failure | Poor steering, unusual movement or failure to change direction | Fault in the servo or its control circuitry |
| 4. Electrical damage | Robot stops unexpectedly or fails to restart | Electrical short, damaged circuitry or power-related fault |
| 5. Intermittent operation | Robot starts, stops or behaves unpredictably | Failing PCB components or internal electrical connections |
| 6. Corrosion | Increasingly unreliable operation, eventually complete failure | Corrosion on PCB tracks, connectors or electronic components |
How to Confirm the PCB Needs Replacing
Before ordering the assembly, a technician should:
- Test the power supply and floating cable.
- Check that the tracks, brushes and impeller rotate freely.
- Inspect the motor block for moisture or corrosion.
- Test the drive and impeller motors for faults.
- Check the servo operation and electrical connections.
- Confirm the motor block can be resealed correctly.
Frequently Asked Questions
Is this a complete sealed motor unit?
No. This listing is for the motor top cover, servo and PCB assembly, not the entire sealed motor unit.
Does this assembly fit the Dolphin M700?
Yes. Dolphin M700 is included in the compatible-model list, alongside M600, Active X6, Ultimate, Aquawize AW6 and Wave 90i.
Does intermittent operation mean the PCB must be replaced?
Not necessarily. Before ordering, a technician should check the power supply, floating cable, moving parts, motors, servo, internal connections and motor-block sealing as outlined above.
