Possible Causes

Corrupted firmware in control PCB, Power surge damage, Failed microcontroller, EEPROM error

How to Fix / Troubleshooting

Safety first: Unplug the pump before any disassembly.

Steps:

  • 1. Power cycle: Disconnect power for at least 10 minutes, then reconnect and attempt to start the pump.
  • 2. Factory reset: If the Flowclear model supports it, perform a factory reset according to the user manual (often a combination of buttons held for several seconds).
  • 3. Surge protection: Use a surge protector to prevent future firmware corruption.
  • 4. Replace PCB: If E13 persists and the pump remains inoperable, the control PCB must be replaced, as firmware is typically not field-flashable on Flowclear units.
