What to Do If Your Ball Pump Displays 'Error Code 8' (E8)?
Applies to Models:
✅ P200
✅ P300
✅ P300 Plus
⚠️ What Does E8 Mean?
The E8 error code indicates a sensor error. This happens when the pump's internal pressure sensor is either damaged or temporarily affected by external interference.
When E8 appears:
-
The error code will display on the screen for 5 seconds
-
Then the device will automatically shut down for safety
🔍 Possible Causes
There are two main reasons for the E8 error:
1. Damaged Pressure Sensor
-
This type of damage is not recoverable
-
A replacement unit will be required
2. External Interference
-
Nearby electromagnetic sources or unusual environmental conditions may affect sensor performance
-
Removing the source of interference may allow the device to return to normal
✅ How to Resolve It
Step 1: Check for Interference
-
Move the device away from strong magnetic fields, electronics, or wireless transmitters
-
Ensure you're in a clean, stable environment
Step 2: Restart the Pump
-
Wait a few moments
-
Turn the device back on
-
If the E8 error disappears, you can continue using the pump normally
Step 3: Still Seeing E8?
If the error returns after restarting or appears repeatedly:
-
It’s likely a sensor hardware failure
